4:30, it's amazing you mention this. When I was a kid my parents switched to Flourescent Lighting over Incandescent, when we tried to eat dinner I had to excuse myself because the food looked so unappetizing after the hue change. Everyone made a big deal out of me excusing myself and was talking about me like it was weird and I was being rediculous, good to see I had a legitimate point.
I have never liked fluorescent lights since I was a little kid but I have to tell you I also hate the LEDs they make me feel sick and they make everything look flat and weird almost like a Twilight Zone when I'm outside and they're coming off of buildings and street lights..... I am proud to say I only have incandescent in my home .
The early flourescent lights were limited in their watts and their color index. In the newer ones you can get much higher light output and much better color. You can even get daylight bulbs now.
True, except that electric heat is more expensive than natural gas. If you heat your house with electricity, than it makes no difference which type of bulbs you use in the winter.
louis tournas They are helpful more than 2 months. It's not just when the air conditioner is on that they help. They will reduce your power bill in all months where the furnace isn't being used. Unless you live on Elsmere Island :-)
My3dviews Furnace? Not many people have one of those diesel burning furnaces. We use electric heaters. Big businesses and shopping locations probably use natural gas. Hydroelectric power!
I've worked in the sustainability & energy efficiency sector. I get many questions from clients & people asking if they should swap their halogen or filament bulbs for LEDs or CFLs. The answer is... it depends on how often & how long you use the light. If its a light that you use often, say >3 hours a day, then the cost-benefit justifies it. It will pay off in a less than a year or two. But if it's a light in the laundry room, storage room, or a vacant room that you only use once or twice a week for less than 15 minutes... then it's better to leave it be & only replace it when it goes. I have an old filament bulb in my laundry room that's been there before the phaseout (filament bulbs were replaced with halogen technology) in 2008.
we went LED through out, in the low uses rooms more cause daylight leds are so bright and pure a white and we can use higher output bubs than was safe when they were incandescent
I changed my CFLs just beacause of the annoying warming up time, specially if you are just going to be there for 5 minutes but I still have an incandescent one in the staircase that the previous owner left and I wonder how many 100 year old bulbs are we going to have in the future.
When I built The House of Steel almost 20 years ago, I installed mostly halogens in the high use areas and incandescents in the low use areas. LEDs were far too expensive at that time. The high voltage halogens aren't particularly long-lived, though the low voltage/low wattage ones are still going strong. I replaced three of the 50W sealed downlights with the highest output LEDs available about three years ago. The LEDs were quite dim (and therefore dangerous; they light my kitchen bench) and the first failed after three months so I returned to using sealed halogens. The incandescents lasted longer than 10 years and were definitely the cheapest option. The short lifespan of the LEDs makes them the most expensive by far. Also the highest energy consumption when you realise that their cost is a function of how much embodied energy they represent. The high voltage 200W linear halogens have a lifespan of ~3-12 months. The sealed dichroics about 12 months. All of the supposedly energy-saving bulbs cost me more than the old incandescent bulbs did. CFLs are lasting quite well in the low use areas, but the ones in my home office only last about the same as halogens, 6-12 months. Also the 12 volt devices consume transformers. They rarely last longer than 2 years.
2 years later: I would advise traditional incandescent bulbs for your nightstand or reading light, also for kitchen. LED lighting is not good for your eyes.
The incandescent bulb may not be dead yet as MIT found a way to greatly improve their efficiency with nanophotonics. These also may be more environmentally friendly to manufacture than CFLs and LEDs.
Ah, the internet. I know it was posted a year ago. But if you'd asked nicely if this person could provide a link, that would have been a decent way to go about it. Just saying "citation or its a lie" makes you look like a royal asshole and nobody will want to provide anything for you. Seeing this comment is like the internet version of stepping in dog shit.
Well all I use is incandescent because I never liked fluorescent , I never liked the compact ones either and I absolutely abhor the LED which make me feel ill .
Thank you for posting an accurate and informative video that covers so many aspects..LED lamps are fast becoming available in a variety of colour temperatures, but a full SED curve will always make them slightly different from conventional lamps. You may not have fully realized that prepared food is dyed to look appetizing. No doubt as LEDs become more common place the food manufacturers will start to use different dyes.
Something else to consider is that medications have dyes in them that look a different color under fluorescent, incandescent, and LED bulbs and it has caused me a little confusion thinking I was given the wrong prescription when I got home looking at my prescription under my new LED bulbs. I was expecting a yellow coloration to the tablets and when I got home they were all white so I thought they had given me the wrong dosage but then at the drugstore it was all back to the right color.
It depends on what wavelengths you're sensitive to. I have no problem with cool white LEDs or CLFs, but I've got family members for whom cool white is a migraine trigger, so I try to make sure all the lights are warm white. A particular pet peeve of mine is when I see LED lights (especially Christmas lights) that are only half-wave rectified (by nature of being a diode), which subsequently give off a 60Hz flicker. You can stick a bunch of LEDs in series and use the collective resistance in place of a dropper, but you're only using half the wave while blocking reverse current on the other half (they burn out quicker that way too). That's another migraine trigger for some people. Full wave rectified, with a smoothing capacitor, is far easier on the eyes.
@thegrandfinale2 Bright visible light doesn't make you go blind. High intensify UV light does. Such as, staring at the sun, or a welding arc without a visor. But staring at a tablet isn't going to do anything to your eyes.
@thegrandfinale2 No, but they did have considerable eye strain. It's no different than sitting in a dark room with a desk lamp. You're not getting any more luminous by using a tablet instead of a desk lamp.
Although the LEDs are very efficient and I use them to light the house, I have to say that I like the incandescent lights better. Interesting thing is that most black fabrics have a slight red tint to them, but under incandescent lighting they look dark red rather than black. Under LED lighting the red color is almost not there, and normal reds look faded. Under incandescent lighting I can easily tell certain black fabrics apart by how red they are. Black plastics just stay black though without any care what lighting they are under. I've got some form of light over-sensitivity. I just thought it is weird and wanted to know if anyone else noticed any of this.
I appreciate the explanation when it comes to the "flickering" of cheaper LEDs... I had bought some night-lights at the Dollar Store that have each have a Blue LED in them. They look fine to the naked eye, but when I look at them through the view-finder of the camera on my phone, they flicker like a strobe light. _Always_ wondered why until now!
A factor a lot of people miss is that in cold climates, the "wasted" heat energy isn't really waste. In fact, if you heat via resistive electric (which a TON of people do) virtually ALL the "wasted" energy is put to use exactly as efficiently as the furnace or baseboards. The mitigating factors are when it's warm enough that you don't need heat, in fact you pay double the penalty if it's hot enough and you have AC running (lightbulb uses 100W to make light +99 watts of heat, ac probably uses 60+ watt's to remove that heat from the house) overall though, in many climate's LED's aren't that much better in the long run (we heat 8-9 month's of the year where i live). not to mention how much more waste goes into the landfill (sure led's say they'll last 25 years....which mean's noone you've heard of has ever had to replace a led bulb yea?) Glass and metal are recyclable, or at least they are inert and won't harm the environment. I'm not so sure the same could be said of the plastics and electrical components that go into led's. Sometime's I feel we've forgotten many aspects of pollution with all talk being focused on AGW
Was about to write something similar. Here in the northern Europe winters are long and dark, time you need to use lights the most. Any savings from lighting during those times is directly moved to heating cost. Only savings you get are during the summers which are very short and bright so you barely use any lights anyway but still the same laws hit us and banned incandescent bulbs. Even if you were living in optimal conditions and got proper savings from leds it's still a piss in a ocean when compared to other polluting things. If you want to save the earth then there are loads of better things to do than go after incandescent bulbs.
interesting comment, a brief look into it though. It seems that the mercury incandescent bulbs contribute is based solely on the fact they use more energy, and fossil fuel powered electrical plants emit mercury. so..not really. We were talking of incandescent bulb use in climate's where it's cold more of the year then it's warm. Since cfl\led isn't really much more efficient when your heating you home via electricity 3\4 of the year, the "extra" mercury put out by powerplants is a moot point.
Halogens became popular in the US in the late 1990s, about when my husband and I got our first apartment. We got a halogen lamp for very cheap, and we were excited to see what energy savings we would get since we were paying for our own electricity. One thing we noticed is that the halogen bulb got very very hot! So hot that it was burning the floating dust in the air and we could see smoke coming off of it, sometimes. One day it knocked over and caught fire! It was a good thing that we were home when it happened. Ever since then I won't use halogen. I am all about saving money but the incandescents will always be my favorite :). Thank you for this amazing video!
Yeah, the person the remodeled my house put in halogen under cabinet lights. OUCH OUCH OUCH, you burn your hand trying to turn them off. I replace them with some 96+ CRI LED light that use less then 1/10th the energy and I can leave them on all day and night, which I did one to test, and it never got hot. They have a LOT more lumens too. It the expensive GE lights. I got some Hyperkions for the spot lights over the cooking area / island since I want high CRI and safe for over a cooking area.
The reason I think incandescent doesn't need to be banned it that it is not inherently dangerous and there are some niche aplications for them (heating with a small amount of light, old appliances etc). LEDs are just becoming so cheap no one in their right mind would buy a worse more expensive bulb.
Ironically, one type of bulb that managed to skirt around these issues so far is "Rough Surface", basically a more sturdier version of incandescent bulbs as they are mostly used in places that may be prone to shock or other rough situations. I picked up some from Dollar Tree a while back (under the Sunbeam name), yet they don't last as long as I hoped, a few burned out within a few days.
Incandescent is still available as heat lamps and automotive use. Halogen bulbs are incandescent with a sensitivity to oils touching the bulb. Still used in some construction lights, but slowly changing to LED. Kitchen circle lights are better as a plug & play LED version. Those are hard to bypass the ballast.
I was working on a house recently that was completely outfitted by LED bulbs that were on sale in town. I was feeling nauseous and I couldn't figure it out, I had to walk outside to overcome it, it was painful being inside with the lights on! This completely explains why! My eyes were straining terribly under the cheap LED light, now I know what to look for and recommend if anyone is considering replacing their incandescent or fluorescent bulbs with LED.
Very interesting video about light bulbs! I have moved into my own apartment a year ago and needed to replace a bunch of lights and I got LED's with the most "daylight" feel. I also bought a "Bug repelling" light bulb and it says the exact same thing on the back. lol
Hey Brainiac75 - We are not seeing voltage and I suspect that your source was not a perfect 230V - This may be the reason why all incandescent lights were showing less power than advertised and under higher drain (400W) difference was even bigger due to higher voltage drop. LED lights with built-in power supplies (not a capacitor dropper ones that flicker) are voltage independent, they will often run from 100V or below up to their "popping" voltage drawing exactly the same power :) They even run on DC. To show how important is voltage drop lets take my 3 kW kettle that I use: It only draws around 2 kW as I'm on the very end of power line and I receive around 220V which drops to 190-195V measured on a socket in the kitchen when I turn on my kettle. That's 2/3 of rated power :)
Thanks for the input. That actually could be the case in my house too. The wattmeter probably isn't extremely accurate either - but the readings for the bulbs should still be relative comparable.
If the voltage is 220VAC the the frequency is 50Hz and that doesn't help with flicker. 117VAC and 60Hz is better because the peak voltage is lower and frequency 17% higher.
That's just how everything goes. We're shutting down coal power plants, because they aren't environmental friendly enough, but we ship all the machinery to third world countries so they can run a coal power plant for many years. A recent one that shut down near me had all the machinery shipped to Nigeria.
But the strange thing is that LED-bulbs are almost as cheap as incandescent bulbs on eBay nowadays, and you'll save a lot of money on power by using LED over incandescent.
+PROTOCOL Some of those cheap ebay LED bulbs don't last long enough for the cost. Cheap junk isn't always low cost. I had a couple LED bulbs that didn't make it to their first hour.
+My3dviews Most of our house is using cheap frosted/matte warm white LEDs from eBay, and they've lasted for about 4 years now. Tried several types until I found one that has a incandescent-like color that doesn't flicker. Can't remember the price on them, but I believe I paid $2 each.
Great video! As a typical mono-linguistic American, the quick lesson in proper pronunciation of Rullepølse was my favorite part. I needed that, thank you.
Maybe I am imagining this, but I literally cannot see well with LED or Flourescent lights. It's bright, but I can't see. It's the strangest experience. I so miss incandescent lightbulbs.
What is the lumen rating of the LED/flouro lights you're using? That's actually what's important. I notice many websites & videos that explain about switching to LED/flouro fail to mention this. The result is many folks end up getting LED/flouro lights that produce a lower light intensity than the filament bulbs they want to replace. For instance, if you want to swap a 60W incandescent, get an LED or CFL that produces 800-1000 lumens.
LED AND FLUORESCENT lights do strobe. Most people don’t notice it but some do. I have read that they can cause seizures in epileptics! If they can do that they could affect some people’s vision.
Eclectic Monstrosity It is not your imagination, I can't see with them either and I refuse to buy them . I am considering getting kerosene lamps . I know the lighting from it won't be as good as I am used to but at least I won't be paying for absolute crap and it will be one less thing using electricity.
@@royrice8597 That exact reason is why I am an EDC flashlight snob. The cheap torches at the chain store may seem bright, but between the blue/purple/green hue, low CRI, and pulsing light you might as well be colorblind when using them.
Funny thing is you can sell indescant bulps if you sell them as heating unit, not light source ;) Funny how EU regulation goes sometimes... Theres engineer in Germany that does this...
I'm a Washington State licensed Union Electrician and I have always had a hard time explaining simple electrical questions like "How does a transformer work?" or "Why can birds sit on power lines without being electrocuted"? without reverting back to theory and how electricity operates at an atomic level because that's how I learned it. When I see their eyes glaze over it's time to try to simplify or create an analogy they can understand. You gave the simplest, most easily understood by the layman, easily cross-referenced examples that I have ever seen.
Viewers- if you're ever buying LED bulbs for in your home, be sure to buy "warm" white and not "cold" white. Cold gives that fake looking effect like Brainiac showed with the meat. I enjoy mine.
Cold white looks terrible in most applications, short of headlights, and interior cabinet or case lighting. It strains the eyes and makes you look like a vampire.
***** 'White light', that is either on the side of cool, or on the side of warm. Natural white is actually very slightly on the side of warm, like sunlight. I am not talking about that yellow orange light like old incandescent bulbs :) Although, that lighting will compliment your complexion.
I slightly disagree :) I'm sitting in a room lit with 4200k CFL's and I really enjoy it: They seem "cold" compared to incandescent or even regular CFL's and slightly warm but close to sunlight with a small shift towards pink during daylight. I have 5500k "photo" type 85W CFL's in my garage and I also like the color there.
8:25 It was just the opposite. Tinted glass was banned immediately while clear glass was allowed for a while. The reason was that the tinting reduce the light though I think it was just to make incandescent less attractive. Incandescent bulbs are still available under name rough service bulbs. They may not be on every store and are not intended for home use.
04:30 Which one looks the most delicious? The word "delicious" has no place in a sentence describing that sliced culinary atrocity, regardless of the lighting.
It's hard to find LED's in the 7000k - 8000k range, except for some auto interiour bulb replacements on ebay. I like that color rendition best. It's white to slightly blue. And looks really good for my Aquariums.
I'll go with those any day instead of LEDs which I hate and I can't stand the compact discs either.... in my home I only use incanndescent.... I don't care if it cost me more . My incandescent amber light bulbs that are low wattage and my hot pink low-wattage light bulbs or what I have on in my home in the evening and it has a nice soft glow.... I bought hot pink LED and also Amber LED and they were horrible flat cold weird electronic light that does not have any warmth or beauty
@@gardensofthegods There are a lot of really good LEDs outside, but they are not cheap at all. But there is nothing wrong with halogen either. Nice that everyone can choose what he wants. At least until the lower wattage are also gone
@@PM-wt3ye some of us can tell the difference between the LEDs they... are electronic.... some people those of us who have had brain damage in the past and other neurological problems can't seem to be able to deal with them . Wow I thought I was fine and then the onslaught from the LEDs out there has created a lot of problems.... as I said I am not the only one complaining about it . A couple months ago I found a website where people in Europe are trying to get them banned .
I know this is an old video of yours, but you mentioned the wattage of your CFL video light being a lot lower than advertised and I felt the need to explain why. There's two reasons for that: Fluorescent lights require a high voltage to create a path for the electrons through the gas inside the tube. However, once this path is created, it can be sustained with less power. Like a TL, a CFL has a little starter built in, which regulates the initial burst of energy needed to create the electron path. CFLs (And TLs) are rated for this start-up power to prevent accidental breaker tripping. The second reason is, to get this high voltage, a transformer is needed. This can offset most conventional power meters because the working current is out of phase (Roughly 90 degrees) with the voltage. This is a side-effect of electromagnetism, and the same principle as to why a magnet falls slower when passing through a roll of tinfoil (aluminum foil)
Here in Germany, halogen bulbs habe been banned from production a few days ago. This means that only the leftover bulbs are allowed to be sold, and if they are sold out, halogen bulbs are gone.
always wondered what ''CRI'' meant, tk u for clearing that up. it is to my belief that the reason the incandescent bulb is still around is because of its high output to keeping the food more stable and fresh . awsome vlog !!
1:41 Actually, I was told it was a mix of Tungsten and Osmium - which is how the OSRAM company (a product of which is seen at 9:20) got its name - OSmium and WolfRAM. They had a factory in my hometown until a few years ago, really liked them, even named a bridge of our inner-city railroad after them.
I could see osmium being useful. It's melting point might be a bit lower (3400K instead of 3695K) but it's also a worse conductor (by about 42%), meaning it should help getting the resistance of the wire up, making heating it up easier.
I think you should still allow people to use their bulb of choice, some things can't beat the look of a incandescent bulb. Also LEDs sometimes suffer in colder climates along with CFL in that they take longer to get to full brightness.
@@Ignisan_66 "Yeah man, governments and their laws, they limit our freedom for no reason! I want my own ambulance strobe lights for example, but they dont let me for some reason. And what if I want a different color for traffic lights? I think they all should be green, it is a beautiful color. Also I hate cops, we should remove them entirely. They are the embodiment of the oppression after all!"
Excellent information! Useful stuff to show my family... I was an Electronics Engineer repairing PC, Laptops, etc., and trying to explain to my family what the differing bulb lights actually used was a nightmare for them, but not this clip! Great.
Nigel Russell Compared to what exactly? A 40W incandescent vs a 40W LED is still 40W of power... The only reason I wanted the 40W LED specifically is for large room/outdoor lighting.
Great video! FYI though, the CRI video test with the meat was likely confounded by white balance differences - to be a fair test, the three would need to be white balanced to their respective sources individually, ideally using a quality white balance reference card (that’s the problem with low CRI lights, even when properly white balances, differences in colt reproduction exist because of holes in the emitted spectrum)
I decided to upgrade my whole house to LED lighting like 2 years ago, and not a single bulb has broken yet. Compare that to the incandescent bulbs I had before that needed to be changed like once every half year if I was lucky. The lighting in my house is so much better now, much brighter. I bought warm LED bulbs because the bluer ones gives me eyestrains, but these work very well.
Certain LED’s also cause wireless interference. I was unable to listen to the FM radio with the lights on (4 LED lights made by FEIT electric) as soon as the lights were turned off, radio signal was great. I didn’t test further, but I highly doubt they only cause interference on the 87.9-107.9 MHZ range, which in itself isn’t good, for electronics or your health. Also the bulbs ran really hot (about 70° C / 160° F), although they are rated for only 21.5 watts.
It's non ionizing radiation, so it really can't damage your cells at a molecular level. The 4G data being transmitted is more potent than any LED circuit driver. Plus the driver only consists of a full bridge rectifier, transformer, capacitor, and voltage regulator
@@danieldyman7196 That doesn't mean it's ok to transmit a lot of noise at those frequencies. Though a bulbs conforming to all the specifications really shouldn't do that and I think most of them don't. Also a 100MHz is a very high frequency that I don't think any switching converter uses.
Yes, and that interference also makes them unsuitable for many garage door openers. I had to tell several neighbours about this, when their openers suddenly started acting in seemingly unpredictable fashion.
I know this video is old, but I think the reason the incandescent bulbs consumed less than they’re rated for and the LEDs not, is that the mains voltage was a bit low, and the incandescent don’t have electronics to adjust for that.
@@danieldyman7196 Lots of them still do have flicker. I had to buy LEDs specifically sold with a flicker-free design when taking product images. The other LED bulbs sold all had flicker and cause banding in images or videos.
Not surprisingly, Europe seems to be ahead of the U.S. in informing the public about LED technology. I love good LEDs but I'm a bit torn since my great uncle developed the technology to produce industrially useful lengths of tungsten wire and the coiled coil filament common in incandescent bulbs.
I found a website last year and you're up where they are trying to outlaw those horrible LED lights because of how bad they are for people and personally I absolutely hate them and only have and canndescent in my home
@@valerierodger7700 Well, it really depends on which LED light you buy. Incandescent lights usually have a color temperature of 2700K, which doesn't excite your sleep hormones too much. Most LED lights are way above 3000K, but lower options are avaiable.
LED actually has one major disadvantage and that is the reactive power they produce. This is caused by the phase shift because of changing the AC to DC. We even tested this years ago in the lab when I was studing and teacher wanted to show us that these "energy saving" bulbs actually used up more electricity than conventional incandescent bulbs. The amount of power they draw from a socket is lower, yes. BUT they also work against the change of the AC current which is harder to measure and can't be seen with the traditional wattage meters which are directly plugged into a socket and that work against the current plus their spent power from the socket was greater than on older incandescent bulbs of same wattage. Plus LEDs are really complicated things to manufacture which create a lot more pollution than just simple incandescent bulbs. Incandescent bulb is just glass, inert gas, tungsten wire, metallic socket head, metals to hold the tungsten wire and some glue between the glass and the socket. LED bulbs in the other hand have circuitboards, some electric components, wires and what not. Incandescent light bulbs could also be easily made to last a lot longer than they used to last. The double helix structure of the wire was the main reason for the wire to snap after certain amount of time. There's one of the very first light bulbs ever produced in the US in one fire department building which has been burning non-stop for tens of years if not over hunderd years. What's so special about it? At least it doesn't have that double helix structure on its wire like modern incandescent light bulbs used to have. Based on these facts in my opinion these "energy saving" light bulbs are one of the biggest scams of all time to actually lure people to waste more energy when they are using them and also when they are produced.
MrBrander I have a 700 square foot room with high ceilings, how should I light the room. We’re using cfl tubes. I want to switch to a healthier light. What should I do. I would very much appreciate your help.
I recently bought a house, and through upgrading the light fittings, I needed some new bulbs. The options I had for LEDs to choose from was incredible. I have the equivalent of 4x 60W bulbs in my living room. They're about 8W each, iirc. Over time, you do get used to the lack of colour though, as I've noted from having a red bulb in my bedroom some years ago. It's just about reprogramming your brain
I've been using LED lights in my house for almost 2 years, all I can say my eyes are tired... headaches.... Yup...i'm switching back to Neons, im not going to sacrifice my health for cheaper electric bills......
Eko Heriyanto you mean those little compact flouresent lights full of Mercury, that if it gets broke inside you should call hazmat to come clean house because the Mercury vapor spreads throughout the house.
@Blind Freddy Leds are flickering, and also blue spectrum light, almost no red light, it doesnt matter what color light you have, warm or cold. I was pioneer in led lights, now Im using classic bulb in my bedroom and workrooms, its a lot healthier, its alot more easy to concentrate and do tiny works under classic bulb
The reason incandescent never reaches it's wattage rating is because the rating is measured at 240v and mains in europe are 230v and during peak hours can dip to 220ish. As a type of resistor, incandescent bulbs would only resist a predefined amount of ampers so unless the voltage is exactly 240v, the bulb will always draw less watts than it's power rating.
If something is more efficient, it means you don't pay to much and there is no need for ban on the other things. We know LED or fluorescent lights are not always better, so there is a ban. We didn't need a ban on CRT TV's, VHS tapes, steam engine trains, open wood or coal fire stoves... Because there was no real benefit to them. If there is a ban, it means only one thing - someone is trying to push their agenda on you. In this case, there is a lot of money to be mage in patents for fluorescent or LED lights, they cost a lot of money so people would not buy them. It is better to have one 40W tungsten bulb on your toilet or pantry for 10 years, rather than paying 15 times more money for LED, which will go bad in few years due to problems with one of the thousands of electronic parts. Or 10 times the money for fluorescent, which will burst every few years, releasing mercury fumes into your home.
It's because incandescents are not very profitable and are also beneficial to your health with the "inefficient" portion of energy they put out. Yes the large amount of beneficial infrared that incandescents give out is good for you. These poison energy saving lights have virtually no infrared in them and also lack real red in their spectrum. Frankenstein lights these are. Sunlight, candles and other controlled fires are the light sources humans have been exposed to throughout their existence on Earth. All of these rich in "wasteful" infrared. The best part of all these light sources is the infrared, especially the near infrared.
"one of the thousands of electronic parts" depending on the lamp, the amount of parts can be less than a couple dozen, on large lamps it can probably be well over 200 at most (most of them being LEDs). Also, in theory LED lamps should be able to outlast incandescent bulbs. Yeah in theory. Despite exaggeration your point stands, an LED lamp is supposed to outlast a regular light bulb but that only happens under lab conditions where they are tested in a nice 23°c constant temperature indoors room being powered by high quality power supplies. In the real world you have 10-12°c temperature changes between day and night, more if you use heating or air conditioning, people turn the lights on and off on irregular intervals, the power lines feed crappy quality power to the bulbs and there are tension/voltage spikes and drops. The last ones absolutely kill LED light bulbs, it really deteriorates them a lot, changes in temperature will also stress the internal components into self destruction (specially capacitors, they dont take high temperatures nicely and die off in a couple years at most). A regular lightbulb wins in my opinion, only because its simplicity makes it quite rugged and not only cheaper to make and manufacture, but also cleaner and more ecological since its literally a bit of glass and metal.
+Mylity 66 Is that theory or experience? I've used leds for years now and have never needed to replace any of them, unlike the incandescents I used before. Never did I buy expensive leds, I bought them cheap from discount sales and found that if I pay attention to color temperature and CRI, I'll have cheap leds that are just as fine. I have no doubt I would've paid the same amount for replacing the incandescents by now; these leds are definitely saving me money. Especially the ones I use most, they save enough money on electricity to make it worthwhile within a few months.
Mexico! That's awesome - welcome aboard and greetings back from Denmark :) Are incandescents banned in Mexico or do you still have the freedom of choosing yourself?
Hi there! Well, here in Mexico most incandescent has been removed from the metropolis, you may still find them in province but never in a supermarket, legally they are yet to be banned. Interestingly enough, you can still find a lot of incandescent with opaque|frosted bulbs, but people dont really buy them anymore and usually prefer halogen ones since LEDs here are about 20x as expensive as a regular and they save important amounts of energy. The industry is slow to change, mostly due cost of products.
Richard Frank Interesting. I wouldn't buy LEDs either if they were 20x as expensive as halogens... In Denmark there's no real difference between the price of incandescent decoration bulbs and similar LEDs. But I am aware that we overpay heavily for the incandescent decoration bulbs :)
I actually went to the local market to take a few pictures on the lightbulbs commonly found here for you to see, probably as common as it gets on any shelf in the world: img.photobucket.com/albums/v237/Fenrir100/IMG_20160911_104749328_zpslt56tc0w.jpg img.photobucket.com/albums/v237/Fenrir100/IMG_20160911_104646205_zpsptxnxaha.jpg img.photobucket.com/albums/v237/Fenrir100/IMG_20160911_104638079_zps26xmjad2.jpg img.photobucket.com/albums/v237/Fenrir100/IMG_20160911_104723620_zpscova66jv.jpg The incandescent decoration bulbs can only be purchased on stores focused only in lightning/decór, and yes, in here they cost as much as a LED indeed, so people either buy halogen or the spiral saving ones, unfortunately, the market of spiral energy-saver bulbs was overflooded with really bad quality products from china, some give as low as 500 hours before failing, in fact the government had to exert temporary bans on these until G&E and Osram (along third parties) could switch production lines locally or import, its kind of easy to tell which one is a knock off or a good one, starting with price, we REALLY dislike chinese produce since for years they have been sending really really REALLY bad products here, some have even been found to contain lead or foreign objects or having its circuits (LEDs) melt and cause a fire. (this is not even only related to tis industry, foods and many other items have been found with issues, specially batteries and ballasts bursting into flames suddenly (explody mcexplodface), when the Safety commission found out they blew a gasket and shut down any lightbulbs's import of any kind from china for almost 2 years (this was 3 years ago). As a result, the prices skyrocketed which delayed the transition greatly, as of now its been normalized but the issue still persist. Fortunately, national production quality have been improving to international levels since the turn of the millennium and nationals are found to be competitive with US brands, but people are waiting for prices to drop, specially in the automotive industry which im quite interested, as Halogen's are being displaced by Xenon and LEDs in a massive take over.
Richard Frank Thanks for sharing. Now I know a little more about the daily life in Mexico :) Not surprised that you also have trouble with very cheap Chinese import... The bulbs look very common. Only thing I noticed as special is the 127 volts. That's not common.
Hahaha when I was a kid, I thought it would be cool to make my room all crazy looking by putting bits of coloured cellophane around my light fixture. It looked really awesome. For a couple of minutes. Then yeah... The melting thing happened.
They were super cheap here as well, so I bought literally hundreds for very cheap. I decided to upgrade to LED anyway (which I think was worth it) and sold off the incandescent ones for over market price because at that point they weren't in store anymore lol
I am very happy now. Thank you all :) Lots of comments and likes already even though this video is about something as trivial as light bulbs. But interesting science is hiding in just about everything... I will read all of your comments now and try to answer questions. - Brian
Sure, but I prefer the cosiness of warm white when I'm eating :) High kelvin seems too clinical and cold for my taste and home. Like visting the dentist... Thanks for the input.
But it's also worth mentioning, that the light emitters have different spectroscopy image: www.popularmechanics.com/technology/gadgets/reviews/g164/incandescent-vs-compact-fluorescent-vs-led-ultimate-light-bulb-test/? Could you publish your comparison chart?
Thank you so much. I've been looking for a vid such as this for quite some time now. As it's now evident, if you want true colors, you'll have to buy a LED that has a much lower lifetime expectancy than the ~80 lamps. From 15.000 down to 2000, just as long as regular oldschool bulbs.
Fumas12 Thanks for watching! Let's see how the market develops in the coming years. At the moment it's difficult/impossible to find LEDs for household lighting with very high CRI...
Here in Brazil those frosted matte inside bulbs were banned still in the 70's, but they glows so nice. I'm looking forward to see them again by these new "filament led" bulbs, for now there is only the clear models. It's kinda ironic that after so much different shapes for the CFL and led bulbs ended up in the very retro model as the led evolves. But lights fixtures with built in leds are increasing, and the flexibility of led application let the using of old interfaces sort of nonsenses, it's like build a robot to do the housework instead of automatic and remote controlled home appliances. So let's enjoy while the led bulbs are still retro!
Fully agree with video. personally I moved to LEDs about a year ago. I change more than 100 incandescent bulbs for Bfranklin's LED. According to my calculation I saved near 200$ for the past year. This is very good result
There's no replacement for incandescent bulbs. I love incandescent, in my apartament all bulbs are incandescent and my electricity bill isn't expensive.
Because it is a tiny apartment, besides 90% of you energy is probably for heating then cooling and lights are way down the list. Your PC alone can use more energy the all the lights in a room on full blast all day. When you get over 2000 SF you will see the bill shoot up even with all the lights out.
Toriless Maybe, but we should be free to use incandescent bulbs and bear the higher cost if it arises. I can't understand the argument for banning the sale of incandescents.
Because the companies the manufacture them weren't getting any sells on their expensive LED bulbs nobody wanted over the old incandescent that costs 10 times less and has less tendency of early failures. Don't let anyone make you believe its to "save the planet" that is bullshit, nowhere in the world households are #1 power consumers (its the industry, but that's normal really) not to mention LED lamps are far dirtier to manufacture AND dispose of/recycle than the simple glass+metal light bulbs. The way to "save the planet" is not punishing the user for using electricity the way they want despite paying for it, but to start phasing out dirty ways to produce it. I'm not against LED lamps, they are extremely efficient and actually a good way to save money on power(so long the damn things last at least half what they state), i'm against forcing people to buy a product even if they don't want it because it might be too pricey for them.
I have no cooling/heating system. The most of energy comes from the electric shower (5500w). I have a 28w incandescent in my room (pretty dimy, great at night), a 70w incandescent on my bathroom and a 105w incandescent at my kitchen. My electricity bill is so low that nobody can understand. Beside giving a bad light, LED messes up with circadian cicle
+Matheus Bitencourt: I live in Canada so I use incandescent most of the year since about 7 months in a year, it is rather cold. In fact, my PC is on all day Saturday and Sunday and it raises the room temp by 3 °C. There is no such thing as saving energy. The heating is electric and sucks a lot of juice. The water heater sucks a lot of juice when the water that comes in is 2 °C in winter time.
I recently bought some oil lamps. 100 CRI flame. THey are gorgeous to look at. It's just different from any LED lighting. Colors pop with warmth. Nicer light than high end Nichia's too (CRI >90).
The power consumption of LED's is a big positive but the negative is the wave lengths of light they emit more of which are harmful to our eyes even metabolism! Lots of new research about this is coming forth so its really interesting.
"English is not my first language but ..." I love it! Well said Sir! "Repel" and "Attract" do, in fact, mean different things, yes. Your statement was completely condescending, yet it comes across as you asking for confirmation of something that you're pretty certain is correct.
Let the consumer decide.. Most will choose LED's. But for some applications incandescent is better spectrum of light. I don't like government taking away options.
Jeg er enig med Jensen. Videoens emne er efter min mening vigtigt og relevant, og noget de fleste vil have stor gavn af at lære mere om. Alt for mange køber desværre bare de samme pærer de altid har købt, uden at tænke over energiforbrug eller levetid. Levetiden har jeg oplevet som et godt argument, når jeg har forsøgt at overbevise folk om at købe mere energieffektiv belysning. "Jamen de pærer er jo fem gange dyrere", har jeg mange gange hørt. Men når jeg så forklarer at de holder 10-30 gange længere og derfor i længden er meget billigere, bliver dem jeg taler med ofte overbevist, og begynder alvorligt at kigge på mere energieffektive pærer. For hvis en pære koster 5 gange så meget men holder 30 gange længere, er dens pris - uanset energiforbrug - kun 1/6 i forhold til levetiden. Det sidste kom du desværre ikke så meget ind på i videoen her. Men det var måske værd at tage op i en fremtidig video? Folk elsker jo, hvis de kan spare penge.
I have checked out 2 of these in the pass and both of them also had a bad LED on the circuit board. The old incandescent light bulbs seem to out last all of these " energy saver lights" I say the incandescent lamps are better in the winter since they also produce heat which actually contributes to the heat in the house. This would make them 100% efficient. There is no energy lost with the incandescent bulbs in the winter as both the light and the heat are used. So which light do you think is the best light to use in the winter?
Cost, starting from scratch, to build incandescent bulbs: A few thousand dollars to make prototypes. A small production line can be started for a few hundred thousand dollars. Technological level: Low. It's possible to make light bulbs in your own garage workshop. Cost, starting from scratch: A 5 million dollar investment, maybe more. Technological level: Very high. Requires full semiconductor fabrication facilities. We are being sold a bill of goods on LED lighting, It is not yet actually living up to its lifespan promise and the cost of the bulb is often greater than the cost of the electricity it is supposed to save over its designed lifetime.
I guess it's not the $ thing that is targeted, but the fact to use less electricity as a lot of it is produced by burning oil or even worse, coal. So there is an "green" thinking in the logic.
I've had the same LED bulbs in my computer room for going on five years now, and instead of needing 120w to light it, I only use 16. Since I'm in here about 35 hours/week, that's 3.64 kwh that I'm not using each week. Even if I stay at tier 1 for my electricity ($.16/kwh), that's about $30/year just for this one room. Over the 5 years I've had them in, it's $150. I guarantee you I didn't pay $75/bulb so, yeah-I'm money ahead. But then, I did the math ahead of time rather than just saying "It won't save money".
Incandescent bulbs require special equipment to evacuate the glass bulbs of air, fill them with special gas, and seal them. Not to mention the specialized equipment to make the filaments. And you'll need to get glass-blowing equipment to make the glass for the bulbs. Get the quality control wrong, and you'll have bulbs that are too dim, too bright, burn out quickly, or explode. It's actually far easier to make LED bulbs. You can just buy the light-producing semiconductors from a supplier, and wire them onto a breadboard with a heat sink, & components from Radio Shack.
I swapped my whole house as soon as i bought it, it's full of old wiring so lowering the loads on circuits is good altogether since the whole upstairs is one circuit which is also part of the basement circuit.
Incadescent halogen 24V DC works for me! Bulbs are like 0,25€. The most pricey is the PSU - roughly ~10€ for a 100W/24V LED PSU. The upside is you can convert any regular AC lamp to DC - just replace the bulb and place the PSU in the circuit between the mains and the lamp. Thanks to DC and lower voltage, not only is the setup more long lasting, the light doesn't present microflicker so many people have eye irritation from. Plus, the scope of the light resembles most that of the sun, which often times cannot be decivesly said about LEDs. It's not that they just produce bad light altogether - it's that there's currently no easy way to test for sure which spectrum of light the commercially available ones produce. And so until there is, and they clearly are marked on the shelves, I rather steer clear of them and keep all their eventual blue light effects away. For those who still do not know about adverse effects of blue spectrum light in 2020, I recommend just a quick Google search - messed up melanoma / sleep cycle production / hastened aging of human body cells etc being the issues mainly discovered and discussed so far, as effects of said blue light exposure. So, DC 24v incadescent halogen.
LED's are blue light. Blue light in excess and beyond the usage at noon, will through off circadian rythym in the masses, and reduce the efficiency of the mitochondria in cells provided enough exposure.
apparently this is strictly limited to the blue spectrum? So, ridding blue and using violet wavelengths looks like it fixes the issue while attaining high CRI? I haven't seen independent 3rd party analysis on this other than from what the Japanese companies themselves push, but I haven't tried to look very hard, either.
I would like it if the places replacing all of the yellow incandescent street lights with LEDs would add a yellow tint, dim them, or do something like that to them because: 1. It hurts my eyes 2. The American Medical Association has warned of issues with the amount of blue light coming from them being bad for our eyes 3. The LED street lights are creating much more light pollution which is bad if you want to see stars and it hurts marine life.
The filament style LED eliminate that problem. I have them on my house for a nice soft glow outside. Turtles actually go towards light, I do not know why.
Very good video getting to see the differences with a watt meter is helpful. I guess I am still old school about energy use. Living in a rural area like I do I know of one example that incandescent's rule. When you have your well house outside you always hang a 100 watt bulb inside to keep the pipes from freezing. Also in the winter when your house is lit up with incandesent's you do get the heat escaping from the bulb into your living space. I would think changing the bulbs in the house to led in the spring / summer months would be ok and changing them back in the fall/winter months to incandescent. The problem I see in banning or not making incandescent is you end up having to come up with some other idea to get the heat/energy you need for whatever purpose rendering less energy use pointless. i am not against the newer technology but you should have a choice in lighting instead of no choice.
@@HappyBeezerStudios A well house is a structure. Usually built with concrete blocks. It houses the spring tank and if you have a water softener that too. Also the line coming in from the well is there also. They are usually 4 to 5 feet deep and have a tilt lid or side access door for service. You normally have to hang a light or heat bulb in there when the winter gets harsh. Usually when you get a constant wind. I usually hang a bulb once the temp gets around 10 deg.
@@checkpointcovid8021 I went to Habitat for Humanity and bought a lot a lot a lot in all my favorite colors and sizes especially the Amber and the hot pink and also some of the red as well as soft pink and the kind that claims to be full spectrum but is not the same as the chromaluxe.... I don't care what anybody says I have the right to have incandescent in my home..... more and more people are complaining to me how much they hate the street lights and how much they hate the lights that are in front of and on the side of the buildings and when they go into the stores . Those shitty LED lights are making a lot of people feel weird and sick
I'm pretty sure that incandescent lights can still be bought normally, as long as they aren't advertised as lights, but heat sources. They still work great in stuff like lava lamps.
You can still buy tungsten filament bulbs from specialist retailers. I bought a pack of 3 100W in London recently, they were old stock. The new ones are more expensive and marked 'industrial use'. They were made in Turkey.
LED lights are more efficient in terms of thermal energy inefficiencies but to entice the public the electronics necessary to convert AC line voltages to power the LEDs are very poorly designed as high frequency inverters used create huge amounts of wide band radio noise pollution. Turn on and AM or FM radio and then turn on and LED "replacement" bulb for an incandescent light....it is terrible!! Cheap electronic designs are causing huge problems and need to be addressed. Then the spectrum of light frequencies for our eyes and those effects - more studies. More needs to be done to abate these issues but very solvable!!
I agree... there should be a nationwide standard for electromagnetic emissions, while there are not long range, it can ruin a Hi-Fi stereo experience while close by.
another match in this world we live, as no wonder as for sATAN himself disguises himself as an angel of light, new bulbs burn so bright but burn out so fast and make more waste where old bulbs like the cinula bulb and my bathroom bulb burn dim but last for years upon years.
The problem with electricity-related issues, such as 'dirty electricity' etc., will be extremely hard to bring attention to and get addressed because as the saying goes, 'out of sight, out of mind', and electricity is invisible, so...

4:30, it's amazing you mention this. When I was a kid my parents switched to Flourescent Lighting over Incandescent, when we tried to eat dinner I had to excuse myself because the food looked so unappetizing after the hue change. Everyone made a big deal out of me excusing myself and was talking about me like it was weird and I was being rediculous, good to see I had a legitimate point.
I have never liked fluorescent lights since I was a little kid but I have to tell you I also hate the LEDs they make me feel sick and they make everything look flat and weird almost like a Twilight Zone when I'm outside and they're coming off of buildings and street lights..... I am proud to say I only have incandescent in my home .
@@gardensofthegods your power bill must be insane
Incandescent light is better than led and florescent lights health-wise.
The early flourescent lights were limited in their watts and their color index. In the newer ones you can get much higher light output and much better color. You can even get daylight bulbs now.
The Sun is the best lamp.
In winter the incandescent bulbs have an efficiency of 100%. The heat is more than welcome then.
True, except that electric heat is more expensive than natural gas. If you heat your house with electricity, than it makes no difference which type of bulbs you use in the winter.
That's why CFL and LED lights don't make sense in Canada. They are only helpful for 2 months or 1 week when room temperature hits 30 °C.
louis tournas They are helpful more than 2 months. It's not just when the air conditioner is on that they help. They will reduce your power bill in all months where the furnace isn't being used. Unless you live on Elsmere Island :-)
My3dviews Furnace? Not many people have one of those diesel burning furnaces. We use electric heaters. Big businesses and shopping locations probably use natural gas.

I love those antique LED bulbs so much, that aesthetic.
I've worked in the sustainability & energy efficiency sector. I get many questions from clients & people asking if they should swap their halogen or filament bulbs for LEDs or CFLs. The answer is... it depends on how often & how long you use the light.
If its a light that you use often, say >3 hours a day, then the cost-benefit justifies it. It will pay off in a less than a year or two. But if it's a light in the laundry room, storage room, or a vacant room that you only use once or twice a week for less than 15 minutes... then it's better to leave it be & only replace it when it goes. I have an old filament bulb in my laundry room that's been there before the phaseout (filament bulbs were replaced with halogen technology) in 2008.
we went LED through out, in the low uses rooms more cause daylight leds are so bright and pure a white and we can use higher output bubs than was safe when they were incandescent
I changed my CFLs just beacause of the annoying warming up time, specially if you are just going to be there for 5 minutes but I still have an incandescent one in the staircase that the previous owner left and I wonder how many 100 year old bulbs are we going to have in the future.
I just found out how bad LEDs are for our health. The ban was a terrible idea.
When I built The House of Steel almost 20 years ago, I installed mostly halogens in the high use areas and incandescents in the low use areas. LEDs were far too expensive at that time. The high voltage halogens aren't particularly long-lived, though the low voltage/low wattage ones are still going strong. I replaced three of the 50W sealed downlights with the highest output LEDs available about three years ago. The LEDs were quite dim (and therefore dangerous; they light my kitchen bench) and the first failed after three months so I returned to using sealed halogens. The incandescents lasted longer than 10 years and were definitely the cheapest option.
The short lifespan of the LEDs makes them the most expensive by far. Also the highest energy consumption when you realise that their cost is a function of how much embodied energy they represent. The high voltage 200W linear halogens have a lifespan of ~3-12 months. The sealed dichroics about 12 months. All of the supposedly energy-saving bulbs cost me more than the old incandescent bulbs did. CFLs are lasting quite well in the low use areas, but the ones in my home office only last about the same as halogens, 6-12 months. Also the 12 volt devices consume transformers. They rarely last longer than 2 years.
2 years later: I would advise traditional incandescent bulbs for your nightstand or reading light, also for kitchen. LED lighting is not good for your eyes.
My incandescent bulbs cost me nothing to operate. I ran an extension cord from my neighbors house.
You can only run 22 60-watt bulbs before you begin to fry the extention cord though, keep that in mind 😂
The incandescent bulb may not be dead yet as MIT found a way to greatly improve their efficiency with nanophotonics.
These also may be more environmentally friendly to manufacture than CFLs and LEDs.
For christ sake just google it. You can't expect citation for all comments.
Yep I heard the same thing and I just googled it is true.
Ah, the internet. I know it was posted a year ago. But if you'd asked nicely if this person could provide a link, that would have been a decent way to go about it. Just saying "citation or its a lie" makes you look like a royal asshole and nobody will want to provide anything for you. Seeing this comment is like the internet version of stepping in dog shit.
I'm still waiting for this :( @ge @phillips??
Well all I use is incandescent because I never liked fluorescent , I never liked the compact ones either and I absolutely abhor the LED which make me feel ill .
Thank you for posting an accurate and informative video that covers so many aspects..LED lamps are fast becoming available in a variety of colour temperatures, but a full SED curve will always make them slightly different from conventional lamps. You may not have fully realized that prepared food is dyed to look appetizing. No doubt as LEDs become more common place the food manufacturers will start to use different dyes.
Something else to consider is that medications have dyes in them that look a different color under fluorescent, incandescent, and LED bulbs and it has caused me a little confusion thinking I was given the wrong prescription when I got home looking at my prescription under my new LED bulbs. I was expecting a yellow coloration to the tablets and when I got home they were all white so I thought they had given me the wrong dosage but then at the drugstore it was all back to the right color.
🤪
Great you have mentioned issues with LEDs! The interesting aspect would be to analyze LED impact on human eyesight...
It depends on what wavelengths you're sensitive to. I have no problem with cool white LEDs or CLFs, but I've got family members for whom cool white is a migraine trigger, so I try to make sure all the lights are warm white. A particular pet peeve of mine is when I see LED lights (especially Christmas lights) that are only half-wave rectified (by nature of being a diode), which subsequently give off a 60Hz flicker. You can stick a bunch of LEDs in series and use the collective resistance in place of a dropper, but you're only using half the wave while blocking reverse current on the other half (they burn out quicker that way too). That's another migraine trigger for some people. Full wave rectified, with a smoothing capacitor, is far easier on the eyes.
I thought you were in a biohazard ppe lmao not a clean suit at the first glance
@thegrandfinale2 Bright visible light doesn't make you go blind. High intensify UV light does. Such as, staring at the sun, or a welding arc without a visor. But staring at a tablet isn't going to do anything to your eyes.
@thegrandfinale2 The old computer nerds who were looking at all those green and amber CRTs 30+ years ago haven't gone blind yet.
@thegrandfinale2 No, but they did have considerable eye strain. It's no different than sitting in a dark room with a desk lamp. You're not getting any more luminous by using a tablet instead of a desk lamp.
thank you. I was totally ignorant about CRI. this gave me good idea about purchasing LED lights
Although the LEDs are very efficient and I use them to light the house, I have to say that I like the incandescent lights better. Interesting thing is that most black fabrics have a slight red tint to them, but under incandescent lighting they look dark red rather than black. Under LED lighting the red color is almost not there, and normal reds look faded. Under incandescent lighting I can easily tell certain black fabrics apart by how red they are. Black plastics just stay black though without any care what lighting they are under. I've got some form of light over-sensitivity. I just thought it is weird and wanted to know if anyone else noticed any of this.
I appreciate the explanation when it comes to the "flickering" of cheaper LEDs...
I had bought some night-lights at the Dollar Store that have each have a Blue LED in them.
They look fine to the naked eye, but when I look at them through the view-finder of the camera on my phone,
they flicker like a strobe light.
_Always_ wondered why until now!
A factor a lot of people miss is that in cold climates, the "wasted" heat energy isn't really waste. In fact, if you heat via resistive electric (which a TON of people do) virtually ALL the "wasted" energy is put to use exactly as efficiently as the furnace or baseboards.
The mitigating factors are when it's warm enough that you don't need heat, in fact you pay double the penalty if it's hot enough and you have AC running (lightbulb uses 100W to make light +99 watts of heat, ac probably uses 60+ watt's to remove that heat from the house)
overall though, in many climate's LED's aren't that much better in the long run (we heat 8-9 month's of the year where i live). not to mention how much more waste goes into the landfill (sure led's say they'll last 25 years....which mean's noone you've heard of has ever had to replace a led bulb yea?) Glass and metal are recyclable, or at least they are inert and won't harm the environment. I'm not so sure the same could be said of the plastics and electrical components that go into led's. Sometime's I feel we've forgotten many aspects of pollution with all talk being focused on AGW
Was about to write something similar. Here in the northern Europe winters are long and dark, time you need to use lights the most. Any savings from lighting during those times is directly moved to heating cost. Only savings you get are during the summers which are very short and bright so you barely use any lights anyway but still the same laws hit us and banned incandescent bulbs.
Even if you were living in optimal conditions and got proper savings from leds it's still a piss in a ocean when compared to other polluting things. If you want to save the earth then there are loads of better things to do than go after incandescent bulbs.
And Denmark itself is in a cold region... Their summers average 60 outside. So yeah.
You forgot to mention the cumulative of mercury vapor to produce these incandescent bulbs in the factories and landfills.
interesting comment, a brief look into it though. It seems that the mercury incandescent bulbs contribute is based solely on the fact they use more energy, and fossil fuel powered electrical plants emit mercury.
so..not really. We were talking of incandescent bulb use in climate's where it's cold more of the year then it's warm. Since cfl\led isn't really much more efficient when your heating you home via electricity 3\4 of the year, the "extra" mercury put out by powerplants is a moot point.
Ben Le
Also, what's the deal about mercury vapor? Another greenhouse gas?
Halogens became popular in the US in the late 1990s, about when my husband and I got our first apartment. We got a halogen lamp for very cheap, and we were excited to see what energy savings we would get since we were paying for our own electricity. One thing we noticed is that the halogen bulb got very very hot! So hot that it was burning the floating dust in the air and we could see smoke coming off of it, sometimes. One day it knocked over and caught fire! It was a good thing that we were home when it happened. Ever since then I won't use halogen. I am all about saving money but the incandescents will always be my favorite :). Thank you for this amazing video!
Yeah, the person the remodeled my house put in halogen under cabinet lights. OUCH OUCH OUCH, you burn your hand trying to turn them off. I replace them with some 96+ CRI LED light that use less then 1/10th the energy and I can leave them on all day and night, which I did one to test, and it never got hot. They have a LOT more lumens too. It the expensive GE lights. I got some Hyperkions for the spot lights over the cooking area / island since I want high CRI and safe for over a cooking area.
The reason I think incandescent doesn't need to be banned it that it is not inherently dangerous and there are some niche aplications for them (heating with a small amount of light, old appliances etc). LEDs are just becoming so cheap no one in their right mind would buy a worse more expensive bulb.
Ironically, one type of bulb that managed to skirt around these issues so far is "Rough Surface", basically a more sturdier version of incandescent bulbs as they are mostly used in places that may be prone to shock or other rough situations. I picked up some from Dollar Tree a while back (under the Sunbeam name), yet they don't last as long as I hoped, a few burned out within a few days.
6 year so far on my LEDs.
Incandescent is still available as heat lamps and automotive use. Halogen bulbs are incandescent with a sensitivity to oils touching the bulb. Still used in some construction lights, but slowly changing to LED. Kitchen circle lights are better as a plug & play LED version. Those are hard to bypass the ballast.
Yeah, only issue is that everywhere is getting rid of fluorescent lights which is dumb. Our house is still full of incandescent bulbs lol
Why are they sensitive to oils?
I was working on a house recently that was completely outfitted by LED bulbs that were on sale in town. I was feeling nauseous and I couldn't figure it out, I had to walk outside to overcome it, it was painful being inside with the lights on! This completely explains why! My eyes were straining terribly under the cheap LED light, now I know what to look for and recommend if anyone is considering replacing their incandescent or fluorescent bulbs with LED.
Actually we switched over the LEDs and hated it, so our house is full of incandescent and fluorescent bulbs again

El esta bien, en el video le preguntaron estas ¿Estas bien? Y el se movió.
i learn more from this man in 11 minutes than a whole year of my schools science curriculum
Very interesting video about light bulbs! I have moved into my own apartment a year ago and needed to replace a bunch of lights and I got LED's with the most "daylight" feel. I also bought a "Bug repelling" light bulb and it says the exact same thing on the back. lol
Hey Brainiac75 - We are not seeing voltage and I suspect that your source was not a perfect 230V - This may be the reason why all incandescent lights were showing less power than advertised and under higher drain (400W) difference was even bigger due to higher voltage drop. LED lights with built-in power supplies (not a capacitor dropper ones that flicker) are voltage independent, they will often run from 100V or below up to their "popping" voltage drawing exactly the same power :) They even run on DC.
To show how important is voltage drop lets take my 3 kW kettle that I use: It only draws around 2 kW as I'm on the very end of power line and I receive around 220V which drops to 190-195V measured on a socket in the kitchen when I turn on my kettle. That's 2/3 of rated power :)
Was about to say the same thing :)
Thanks for the input. That actually could be the case in my house too. The wattmeter probably isn't extremely accurate either - but the readings for the bulbs should still be relative comparable.
If the voltage is 220VAC the the frequency is 50Hz and that doesn't help with flicker. 117VAC and 60Hz is better because the peak voltage is lower and frequency 17% higher.
Voltage drop, BS!
I have no problem saying Rullepølse :D
Ponk 80 me too, it's funny
Yeah I just pronounce it Rullepølse
Raffepaffe. Nope, just can't do it.
just say pastrami
LOL, No shit 😆 🇩🇰
dont worry, those outdated bulbs will survive production a long time here in the third world!
thats what i was going to say about, second and third world countries are still using and will be using them for a long long time.
That's just how everything goes. We're shutting down coal power plants, because they aren't environmental friendly enough, but we ship all the machinery to third world countries so they can run a coal power plant for many years. A recent one that shut down near me had all the machinery shipped to Nigeria.
But the strange thing is that LED-bulbs are almost as cheap as incandescent bulbs on eBay nowadays, and you'll save a lot of money on power by using LED over incandescent.
+PROTOCOL Some of those cheap ebay LED bulbs don't last long enough for the cost. Cheap junk isn't always low cost. I had a couple LED bulbs that didn't make it to their first hour.
+My3dviews Most of our house is using cheap frosted/matte warm white LEDs from eBay, and they've lasted for about 4 years now. Tried several types until I found one that has a incandescent-like color that doesn't flicker. Can't remember the price on them, but I believe I paid $2 each.
Very, very informative, thank you
+Sword depends on the source , if you use a cheap led it will look like crap , but if you buy a good high quality one you will take your words back .

Thank you for this video. It was interesting to learn about the different bulb type, ratings and especially the color output.
Maybe I am imagining this, but I literally cannot see well with LED or Flourescent lights. It's bright, but I can't see. It's the strangest experience. I so miss incandescent lightbulbs.
What is the lumen rating of the LED/flouro lights you're using? That's actually what's important. I notice many websites & videos that explain about switching to LED/flouro fail to mention this. The result is many folks end up getting LED/flouro lights that produce a lower light intensity than the filament bulbs they want to replace.
For instance, if you want to swap a 60W incandescent, get an LED or CFL that produces 800-1000 lumens.
It could also be the color temp.
LED AND FLUORESCENT lights do strobe. Most people don’t notice it but some do. I have read that they can cause seizures in epileptics! If they can do that they could affect some people’s vision.
Eclectic Monstrosity It is not your imagination, I can't see with them either and I refuse to buy them . I am considering getting kerosene lamps . I know the lighting from it won't be as good as I am used to but at least I won't be paying for absolute crap and it will be one less thing using electricity.
@@royrice8597 That exact reason is why I am an EDC flashlight snob. The cheap torches at the chain store may seem bright, but between the blue/purple/green hue, low CRI, and pulsing light you might as well be colorblind when using them.
Funny thing is you can sell indescant bulps if you sell them as heating unit, not light source ;) Funny how EU regulation goes sometimes... Theres engineer in Germany that does this...
Hehe, yes. Predicting the imagination and creativity of millions of people is tricky ;)
As a heater they are decently efficient.
I'm a Washington State licensed Union Electrician and I have always had a hard time explaining simple electrical questions like "How does a transformer work?" or "Why can birds sit on power lines without being electrocuted"? without reverting back to theory and how electricity operates at an atomic level because that's how I learned it. When I see their eyes glaze over it's time to try to simplify or create an analogy they can understand. You gave the simplest, most easily understood by the layman, easily cross-referenced examples that I have ever seen.
Viewers- if you're ever buying LED bulbs for in your home, be sure to buy "warm" white and not "cold" white. Cold gives that fake looking effect like Brainiac showed with the meat. I enjoy mine.
Ikeas ones are also quite warm, but may cost a bit more
Cold white looks terrible in most applications, short of headlights, and interior cabinet or case lighting. It strains the eyes and makes you look like a vampire.
***** 'White light', that is either on the side of cool, or on the side of warm. Natural white is actually very slightly on the side of warm, like sunlight. I am not talking about that yellow orange light like old incandescent bulbs :) Although, that lighting will compliment your complexion.
Philips Hue LED bulbs costs a lot, but they're the best I've seen with a high CRI index and adjustable color temperature.
I slightly disagree :) I'm sitting in a room lit with 4200k CFL's and I really enjoy it: They seem "cold" compared to incandescent or even regular CFL's and slightly warm but close to sunlight with a small shift towards pink during daylight. I have 5500k "photo" type 85W CFL's in my garage and I also like the color there.
Another interesting point to mention, LED lights come with some negative health effects as compared to the older alternatives. Look it up!
8:25 It was just the opposite. Tinted glass was banned immediately while clear glass was allowed for a while. The reason was that the tinting reduce the light though I think it was just to make incandescent less attractive.
Incandescent bulbs are still available under name rough service bulbs. They may not be on every store and are not intended for home use.
04:30 Which one looks the most delicious? The word "delicious" has no place in a sentence describing that sliced culinary atrocity, regardless of the lighting.
I personally like halogen bulbs for my workshop. They produce a nice white color and are very bright.
They are NOT white, they are very warm "yelloish". But if you like those best, its up to you.
It's hard to find LED's in the 7000k - 8000k range, except for some auto interiour bulb replacements on ebay. I like that color rendition best. It's white to slightly blue. And looks really good for my Aquariums.
I'll go with those any day instead of LEDs which I hate and I can't stand the compact discs either.... in my home I only use
incanndescent.... I don't care if it cost me more .
My incandescent amber light bulbs that are low wattage and my hot pink low-wattage light bulbs or what I have on in my home in the evening and it has a nice soft glow.... I bought hot pink LED and also Amber LED and they were horrible flat cold weird electronic light that does not have any warmth or beauty
@@gardensofthegods There are a lot of really good LEDs outside, but they are not cheap at all.
But there is nothing wrong with halogen either. Nice that everyone can choose what he wants. At least until the lower wattage are also gone
@@PM-wt3ye some of us can tell the difference between the LEDs they... are electronic.... some people those of us who have had brain damage in the past and other neurological problems can't seem to be able to deal with them . Wow I thought I was fine and then the onslaught from the LEDs out there has created a lot of problems.... as I said I am not the only one complaining about it . A couple months ago I found a website where people in Europe are trying to get them banned .
I know this is an old video of yours, but you mentioned the wattage of your CFL video light being a lot lower than advertised and I felt the need to explain why. There's two reasons for that:
Fluorescent lights require a high voltage to create a path for the electrons through the gas inside the tube. However, once this path is created, it can be sustained with less power. Like a TL, a CFL has a little starter built in, which regulates the initial burst of energy needed to create the electron path. CFLs (And TLs) are rated for this start-up power to prevent accidental breaker tripping.
The second reason is, to get this high voltage, a transformer is needed. This can offset most conventional power meters because the working current is out of phase (Roughly 90 degrees) with the voltage. This is a side-effect of electromagnetism, and the same principle as to why a magnet falls slower when passing through a roll of tinfoil (aluminum foil)
Here in Germany, halogen bulbs habe been banned from production a few days ago. This means that only the leftover bulbs are allowed to be sold, and if they are sold out, halogen bulbs are gone.
What you said about sodium vapour lamps take that back!! They look brilliant!
always wondered what ''CRI'' meant, tk u for clearing that up.
it is to my belief that the reason the incandescent bulb is still around is because of its high output to keeping the food more stable and fresh .
awsome vlog !!
1:41 Actually, I was told it was a mix of Tungsten and Osmium - which is how the OSRAM company (a product of which is seen at 9:20) got its name - OSmium and WolfRAM. They had a factory in my hometown until a few years ago, really liked them, even named a bridge of our inner-city railroad after them.
I could see osmium being useful. It's melting point might be a bit lower (3400K instead of 3695K) but it's also a worse conductor (by about 42%), meaning it should help getting the resistance of the wire up, making heating it up easier.
I think you should still allow people to use their bulb of choice, some things can't beat the look of a incandescent bulb. Also LEDs sometimes suffer in colder climates along with CFL in that they take longer to get to full brightness.
Exactly. I hate when stupid governments dictate what lightbulbs folks should use.
@@Ignisan_66 "Yeah man, governments and their laws, they limit our freedom for no reason! I want my own ambulance strobe lights for example, but they dont let me for some reason. And what if I want a different color for traffic lights? I think they all should be green, it is a beautiful color. Also I hate cops, we should remove them entirely. They are the embodiment of the oppression after all!"
Excellent information! Useful stuff to show my family... I was an Electronics Engineer repairing PC, Laptops, etc., and trying to explain to my family what the differing bulb lights actually used was a nightmare for them, but not this clip! Great.
I remember when my house has a heat bulb in the bathroom for when you got out of the shower, it was so nice as warm😊

@@kiyang9186 thank you..
just idly looking for the difference between the two bulbs and I did not expect to get this extreme explanation.
I really want one of those 40W LEDs now... I don't care how impractical it is, I want one.
Hehe, I also just had to buy it when I found it. Big size still counts :D
Brainiac75 I know right :)
get some youll save a lot of power in the long run.
Nigel Russell Compared to what exactly?
A 40W incandescent vs a 40W LED is still 40W of power...
The only reason I wanted the 40W LED specifically is for large room/outdoor lighting.
a 40watt incadecent bulb will not out put as much light as a 40w led bulb. as much of the power is converted to heat.
Great video! FYI though, the CRI video test with the meat was likely confounded by white balance differences - to be a fair test, the three would need to be white balanced to their respective sources individually, ideally using a quality white balance reference card (that’s the problem with low CRI lights, even when properly white balances, differences in colt reproduction exist because of holes in the emitted spectrum)
I decided to upgrade my whole house to LED lighting like 2 years ago, and not a single bulb has broken yet. Compare that to the incandescent bulbs I had before that needed to be changed like once every half year if I was lucky. The lighting in my house is so much better now, much brighter. I bought warm LED bulbs because the bluer ones gives me eyestrains, but these work very well.
Certain LED’s also cause wireless interference. I was unable to listen to the FM radio with the lights on (4 LED lights made by FEIT electric) as soon as the lights were turned off, radio signal was great. I didn’t test further, but I highly doubt they only cause interference on the 87.9-107.9 MHZ range, which in itself isn’t good, for electronics or your health.
Also the bulbs ran really hot (about 70° C / 160° F), although they are rated for only 21.5 watts.
It's non ionizing radiation, so it really can't damage your cells at a molecular level. The 4G data being transmitted is more potent than any LED circuit driver. Plus the driver only consists of a full bridge rectifier, transformer, capacitor, and voltage regulator
@@danieldyman7196 That doesn't mean it's ok to transmit a lot of noise at those frequencies. Though a
bulbs conforming to all the specifications really shouldn't do that and I think most of them don't. Also a 100MHz is a very high frequency that I don't think any switching converter uses.
Yes, and that interference also makes them unsuitable for many garage door openers. I had to tell several neighbours about this, when their openers suddenly started acting in seemingly unpredictable fashion.
I really like your style of commenting the video(s).
Greetings from Germany :D
Thanks. I spend a lot of time on the voice-overs - nice to hear it isn't a waste of time. Greetings back from Denmark!
+Brainiac75 You can definitely tell the amount of time you spend. It's definitely appreciated. Your voiceovers and videos are great!
Thank you for your support :)
I know this video is old, but I think the reason the incandescent bulbs consumed less than they’re rated for and the LEDs not, is that the mains voltage was a bit low, and the incandescent don’t have electronics to adjust for that.
for filming to flicker on the led you could have recorded slomo.I recorded a led bulb in slomo at 240fps with a iphone6+ and it shows the flicker.
Those old bulbs didn't use a capacitor or a full bridge rectifier. Modern LED's don't have flicker
@@danieldyman7196 Lots of them still do have flicker. I had to buy LEDs specifically sold with a flicker-free design when taking product images. The other LED bulbs sold all had flicker and cause banding in images or videos.
wow with this video i've learned more than in my chemistry class
Not surprisingly, Europe seems to be ahead of the U.S. in informing the public about LED technology. I love good LEDs but I'm a bit torn since my great uncle developed the technology to produce industrially useful lengths of tungsten wire and the coiled coil filament common in incandescent bulbs.
I changed most of the bulb in my house to LED, and ever since I started to feel more tired.
Probably more work than you have done in a while.
I found a website last year and you're up where they are trying to outlaw those horrible LED lights because of how bad they are for people and personally I absolutely hate them and only have and canndescent in my home
@@valerierodger7700 Well, it really depends on which LED light you buy. Incandescent lights usually have a color temperature of 2700K, which doesn't excite your sleep hormones too much. Most LED lights are way above 3000K, but lower options are avaiable.
@@Minecraftminer3000 Yea better off getting warmer colors
LED actually has one major disadvantage and that is the reactive power they produce. This is caused by the phase shift because of changing the AC to DC. We even tested this years ago in the lab when I was studing and teacher wanted to show us that these "energy saving" bulbs actually used up more electricity than conventional incandescent bulbs. The amount of power they draw from a socket is lower, yes. BUT they also work against the change of the AC current which is harder to measure and can't be seen with the traditional wattage meters which are directly plugged into a socket and that work against the current plus their spent power from the socket was greater than on older incandescent bulbs of same wattage.
Plus LEDs are really complicated things to manufacture which create a lot more pollution than just simple incandescent bulbs. Incandescent bulb is just glass, inert gas, tungsten wire, metallic socket head, metals to hold the tungsten wire and some glue between the glass and the socket.
LED bulbs in the other hand have circuitboards, some electric components, wires and what not.
Incandescent light bulbs could also be easily made to last a lot longer than they used to last. The double helix structure of the wire was the main reason for the wire to snap after certain amount of time. There's one of the very first light bulbs ever produced in the US in one fire department building which has been burning non-stop for tens of years if not over hunderd years. What's so special about it? At least it doesn't have that double helix structure on its wire like modern incandescent light bulbs used to have.
Based on these facts in my opinion these "energy saving" light bulbs are one of the biggest scams of all time to actually lure people to waste more energy when they are using them and also when they are produced.
Here in my house, I have two G.E's incandescent bulbs in two different lamps working for more than 15 years!
MrBrander I have a 700 square foot room with high ceilings, how should I light the room. We’re using cfl tubes. I want to switch to a healthier light. What should I do. I would very much appreciate your help.
@@mangomadness8635 get warmer white flourecent tubes
@@mangomadness8635 If you can find them, get regular incandescent bulbs..!
I recently bought a house, and through upgrading the light fittings, I needed some new bulbs. The options I had for LEDs to choose from was incredible. I have the equivalent of 4x 60W bulbs in my living room. They're about 8W each, iirc. Over time, you do get used to the lack of colour though, as I've noted from having a red bulb in my bedroom some years ago. It's just about reprogramming your brain
6:55 the NorthStar Antique Clear bulb has a very nice Lumen/Watt rating
I've been using LED lights in my house for almost 2 years, all I can say my eyes are tired... headaches....
Yup...i'm switching back to Neons, im not going to sacrifice my health for cheaper electric bills......
Eko Heriyanto you mean those little compact flouresent lights full of Mercury, that if it gets broke inside you should call hazmat to come clean house because the Mercury vapor spreads throughout the house.
are you using cool LED lights? if so you might want to consider getting the warm vareity
Get the LED Warm white ones... they look Cozy
What about Greta Thunberg's needs? Fuck your eyes, those babies belong to her
@Blind Freddy Leds are flickering, and also blue spectrum light, almost no red light, it doesnt matter what color light you have, warm or cold. I was pioneer in led lights, now Im using classic bulb in my bedroom and workrooms, its a lot healthier, its alot more easy to concentrate and do tiny works under classic bulb
The reason incandescent never reaches it's wattage rating is because the rating is measured at 240v and mains in europe are 230v and during peak hours can dip to 220ish. As a type of resistor, incandescent bulbs would only resist a predefined amount of ampers so unless the voltage is exactly 240v, the bulb will always draw less watts than it's power rating.
If something is more efficient, it means you don't pay to much and there is no need for ban on the other things. We know LED or fluorescent lights are not always better, so there is a ban. We didn't need a ban on CRT TV's, VHS tapes, steam engine trains, open wood or coal fire stoves... Because there was no real benefit to them. If there is a ban, it means only one thing - someone is trying to push their agenda on you. In this case, there is a lot of money to be mage in patents for fluorescent or LED lights, they cost a lot of money so people would not buy them. It is better to have one 40W tungsten bulb on your toilet or pantry for 10 years, rather than paying 15 times more money for LED, which will go bad in few years due to problems with one of the thousands of electronic parts. Or 10 times the money for fluorescent, which will burst every few years, releasing mercury fumes into your home.
yes!!! Always ask "Cui bono?" - "for whose benefit?". If there is a ban, it's never because something is better.
Actually... There is a need to ban the coal fire stoves - They are much cheaper to operate but pollute like crazy!
It's because incandescents are not very profitable and are also beneficial to your health with the "inefficient" portion of energy they put out. Yes the large amount of beneficial infrared that incandescents give out is good for you. These poison energy saving lights have virtually no infrared in them and also lack real red in their spectrum. Frankenstein lights these are. Sunlight, candles and other controlled fires are the light sources humans have been exposed to throughout their existence on Earth. All of these rich in "wasteful" infrared. The best part of all these light sources is the infrared, especially the near infrared.
"one of the thousands of electronic parts" depending on the lamp, the amount of parts can be less than a couple dozen, on large lamps it can probably be well over 200 at most (most of them being LEDs). Also, in theory LED lamps should be able to outlast incandescent bulbs. Yeah in theory.
Despite exaggeration your point stands, an LED lamp is supposed to outlast a regular light bulb but that only happens under lab conditions where they are tested in a nice 23°c constant temperature indoors room being powered by high quality power supplies. In the real world you have 10-12°c temperature changes between day and night, more if you use heating or air conditioning, people turn the lights on and off on irregular intervals, the power lines feed crappy quality power to the bulbs and there are tension/voltage spikes and drops. The last ones absolutely kill LED light bulbs, it really deteriorates them a lot, changes in temperature will also stress the internal components into self destruction (specially capacitors, they dont take high temperatures nicely and die off in a couple years at most).
A regular lightbulb wins in my opinion, only because its simplicity makes it quite rugged and not only cheaper to make and manufacture, but also cleaner and more ecological since its literally a bit of glass and metal.
+Mylity 66 Is that theory or experience? I've used leds for years now and have never needed to replace any of them, unlike the incandescents I used before. Never did I buy expensive leds, I bought them cheap from discount sales and found that if I pay attention to color temperature and CRI, I'll have cheap leds that are just as fine. I have no doubt I would've paid the same amount for replacing the incandescents by now; these leds are definitely saving me money. Especially the ones I use most, they save enough money on electricity to make it worthwhile within a few months.
What a fantastic video, you have gained a subscriber, thank you and greetings from Mexico!
Mexico! That's awesome - welcome aboard and greetings back from Denmark :) Are incandescents banned in Mexico or do you still have the freedom of choosing yourself?
Hi there! Well, here in Mexico most incandescent has been removed from the metropolis, you may still find them in province but never in a supermarket, legally they are yet to be banned. Interestingly enough, you can still find a lot of incandescent with opaque|frosted bulbs, but people dont really buy them anymore and usually prefer halogen ones since LEDs here are about 20x as expensive as a regular and they save important amounts of energy. The industry is slow to change, mostly due cost of products.
Richard Frank Interesting. I wouldn't buy LEDs either if they were 20x as expensive as halogens... In Denmark there's no real difference between the price of incandescent decoration bulbs and similar LEDs. But I am aware that we overpay heavily for the incandescent decoration bulbs :)
I actually went to the local market to take a few pictures on the lightbulbs commonly found here for you to see, probably as common as it gets on any shelf in the world:

The incandescent decoration bulbs can only be purchased on stores focused only in lightning/decór, and yes, in here they cost as much as a LED indeed, so people either buy halogen or the spiral saving ones, unfortunately, the market of spiral energy-saver bulbs was overflooded with really bad quality products from china, some give as low as 500 hours before failing, in fact the government had to exert temporary bans on these until G&E and Osram (along third parties) could switch production lines locally or import, its kind of easy to tell which one is a knock off or a good one, starting with price, we REALLY dislike chinese produce since for years they have been sending really really REALLY bad products here, some have even been found to contain lead or foreign objects or having its circuits (LEDs) melt and cause a fire. (this is not even only related to tis industry, foods and many other items have been found with issues, specially batteries and ballasts bursting into flames suddenly (explody mcexplodface), when the Safety commission found out they blew a gasket and shut down any lightbulbs's import of any kind from china for almost 2 years (this was 3 years ago). As a result, the prices skyrocketed which delayed the transition greatly, as of now its been normalized but the issue still persist.
Fortunately, national production quality have been improving to international levels since the turn of the millennium and nationals are found to be competitive with US brands, but people are waiting for prices to drop, specially in the automotive industry which im quite interested, as Halogen's are being displaced by Xenon and LEDs in a massive take over.
Richard Frank Thanks for sharing. Now I know a little more about the daily life in Mexico :)
Not surprised that you also have trouble with very cheap Chinese import... The bulbs look very common. Only thing I noticed as special is the 127 volts. That's not common.
There! So now I know a little more about lightbulbs than I did before. It was a pleasure to watch and to listen to this video.
Anyone else remember back in the day melting stuff on lightbulbs?
Think I'm a little blind now lol
Hahaha when I was a kid, I thought it would be cool to make my room all crazy looking by putting bits of coloured cellophane around my light fixture. It looked really awesome. For a couple of minutes. Then yeah... The melting thing happened.
Yes. When I was a kid, I put Crayons on the bulbs.
@@gordselectronicshobby3853 me too!
I remember stocking up on incandescents when they banned them.cause they were cheap. bought out a stores supply. still using em today
John Johnson as did I 😁💡
They were super cheap here as well, so I bought literally hundreds for very cheap. I decided to upgrade to LED anyway (which I think was worth it) and sold off the incandescent ones for over market price because at that point they weren't in store anymore lol
I still use them and you can still buy them but those of us who bought them early saved money

Could you publish your comparison chart?
Thank you so much. I've been looking for a vid such as this for quite some time now. As it's now evident, if you want true colors, you'll have to buy a LED that has a much lower lifetime expectancy than the ~80 lamps. From 15.000 down to 2000, just as long as regular oldschool bulbs.
Fumas12 Thanks for watching! Let's see how the market develops in the coming years. At the moment it's difficult/impossible to find LEDs for household lighting with very high CRI...

did you ever think about making a comparision of differenta type of LEDs?
Here in Brazil those frosted matte inside bulbs were banned still in the 70's, but they glows so nice. I'm looking forward to see them again by these new "filament led" bulbs, for now there is only the clear models. It's kinda ironic that after so much different shapes for the CFL and led bulbs ended up in the very retro model as the led evolves. But lights fixtures with built in leds are increasing, and the flexibility of led application let the using of old interfaces sort of nonsenses, it's like build a robot to do the housework instead of automatic and remote controlled home appliances. So let's enjoy while the led bulbs are still retro!
3:51 love this tiny bit of humor! Kudos mate, thx! Ofc I did thumbs up it :)
I have cases of incandescent bulbs stored for a lifetime of use. Sometimes only an incandescent bulb will do.
That's all I have in my home and I stocked up on a lot of them that I bought dirt cheap at Habitat for Humanity
Fully agree with video. personally I moved to LEDs about a year ago. I change more than 100 incandescent bulbs for Bfranklin's LED. According to my calculation I saved near 200$ for the past year. This is very good result
A very good-very informative video that I watched 3 times... thanks... one thing though, use a human narrator instead of a computer next time.
Aw! That's not nice! :P
Id rather sound like this guy then be so stupid, that I have to watch the video 3 times...
...and you do.
+David Grohl LMAO
There's no replacement for incandescent bulbs. I love incandescent, in my apartament all bulbs are incandescent and my electricity bill isn't expensive.
Because it is a tiny apartment, besides 90% of you energy is probably for heating then cooling and lights are way down the list. Your PC alone can use more energy the all the lights in a room on full blast all day. When you get over 2000 SF you will see the bill shoot up even with all the lights out.
Toriless Maybe, but we should be free to use incandescent bulbs and bear the higher cost if it arises. I can't understand the argument for banning the sale of incandescents.
Because the companies the manufacture them weren't getting any sells on their expensive LED bulbs nobody wanted over the old incandescent that costs 10 times less and has less tendency of early failures.
Don't let anyone make you believe its to "save the planet" that is bullshit, nowhere in the world households are #1 power consumers (its the industry, but that's normal really) not to mention LED lamps are far dirtier to manufacture AND dispose of/recycle than the simple glass+metal light bulbs.
The way to "save the planet" is not punishing the user for using electricity the way they want despite paying for it, but to start phasing out dirty ways to produce it. I'm not against LED lamps, they are extremely efficient and actually a good way to save money on power(so long the damn things last at least half what they state), i'm against forcing people to buy a product even if they don't want it because it might be too pricey for them.
I have no cooling/heating system. The most of energy comes from the electric shower (5500w).
I have a 28w incandescent in my room (pretty dimy, great at night), a 70w incandescent on my bathroom and a 105w incandescent at my kitchen. My electricity bill is so low that nobody can understand.
Beside giving a bad light, LED messes up with circadian cicle
+Matheus Bitencourt:
I live in Canada so I use incandescent most of the year since about 7 months in a year, it is rather cold.
In fact, my PC is on all day Saturday and Sunday and it raises the room temp by 3 °C.
There is no such thing as saving energy. The heating is electric and sucks a lot of juice.
The water heater sucks a lot of juice when the water that comes in is 2 °C in winter time.
I recently bought some oil lamps. 100 CRI flame. THey are gorgeous to look at. It's just different from any LED lighting. Colors pop with warmth. Nicer light than high end Nichia's too (CRI >90).
Rullepölse.. sounds funnny :D

The power consumption of LED's is a big positive but the negative is the wave lengths of light they emit more of which are harmful to our eyes even metabolism! Lots of new research about this is coming forth so its really interesting.
"English is not my first language but ..."
I love it! Well said Sir!
"Repel" and "Attract" do, in fact, mean different things, yes.
Your statement was completely condescending, yet it comes across as you asking for confirmation of something that you're pretty certain is correct.
Let the consumer decide.. Most will choose LED's. But for some applications incandescent is better spectrum of light. I don't like government taking away options.
Super fedt indhold Braniac! Keep it up :)
Tak - much more to come :D
Jeg er enig med Jensen. Videoens emne er efter min mening vigtigt og relevant, og noget de fleste vil have stor gavn af at lære mere om.
Alt for mange køber desværre bare de samme pærer de altid har købt, uden at tænke over energiforbrug eller levetid.
Levetiden har jeg oplevet som et godt argument, når jeg har forsøgt at overbevise folk om at købe mere energieffektiv belysning. "Jamen de pærer er jo fem gange dyrere", har jeg mange gange hørt. Men når jeg så forklarer at de holder 10-30 gange længere og derfor i længden er meget billigere, bliver dem jeg taler med ofte overbevist, og begynder alvorligt at kigge på mere energieffektive pærer. For hvis en pære koster 5 gange så meget men holder 30 gange længere, er dens pris - uanset energiforbrug - kun 1/6 i forhold til levetiden.
Det sidste kom du desværre ikke så meget ind på i videoen her. Men det var måske værd at tage op i en fremtidig video? Folk elsker jo, hvis de kan spare penge.
love this. especially love when you try to teach us to pronounce whatever that food is
I am against bans as well, however, the state should not have the power to dictate to you, a free person, what kind of bulb to use.
It's not illegal to use them, just to sell them
It's like using a fork to eat soup because you don't know spoons yet.
Yeah, put mercury in your hot dogs!
I agree, repeal the ban on murder. The state should not have the power to dictate to you, a free person, what kind of interactions to have.
@@gooscarguitar that's just a roundabout way to ban you from having them. If nobody can sell, that means you can't have
I forgot what food looks like under anything but the dim light of my monitor.
I have checked out 2 of these in the pass and both of them also had a bad LED on the circuit board. The old incandescent light bulbs seem to out last all of these " energy saver lights" I say the incandescent lamps are better in the winter since they also produce heat which actually contributes to the heat in the house. This would make them 100% efficient. There is no energy lost with the incandescent bulbs in the winter as both the light and the heat are used. So which light do you think is the best light to use in the winter?
Cost, starting from scratch, to build incandescent bulbs: A few thousand dollars to make prototypes. A small production line can be started for a few hundred thousand dollars.
Technological level: Low. It's possible to make light bulbs in your own garage workshop.
Cost, starting from scratch: A 5 million dollar investment, maybe more. Technological level: Very high. Requires full semiconductor fabrication facilities.
We are being sold a bill of goods on LED lighting, It is not yet actually living up to its lifespan promise and the cost of the bulb is often greater than the cost of the electricity it is supposed to save over its designed lifetime.
I guess it's not the $ thing that is targeted, but the fact to use less electricity as a lot of it is produced by burning oil or even worse, coal. So there is an "green" thinking in the logic.
I've had the same LED bulbs in my computer room for going on five years now, and instead of needing 120w to light it, I only use 16. Since I'm in here about 35 hours/week, that's 3.64 kwh that I'm not using each week. Even if I stay at tier 1 for my electricity ($.16/kwh), that's about $30/year just for this one room. Over the 5 years I've had them in, it's $150. I guarantee you I didn't pay $75/bulb so, yeah-I'm money ahead. But then, I did the math ahead of time rather than just saying "It won't save money".
Incandescent bulbs require special equipment to evacuate the glass bulbs of air, fill them with special gas, and seal them. Not to mention the specialized equipment to make the filaments. And you'll need to get glass-blowing equipment to make the glass for the bulbs. Get the quality control wrong, and you'll have bulbs that are too dim, too bright, burn out quickly, or explode.
It's actually far easier to make LED bulbs. You can just buy the light-producing semiconductors from a supplier, and wire them onto a breadboard with a heat sink, & components from Radio Shack.
I swapped my whole house as soon as i bought it, it's full of old wiring so lowering the loads on circuits is good altogether since the whole upstairs is one circuit which is also part of the basement circuit.
I hate that ban! What did the poor incandescent and halogen and fluorescent bulbs do?
Incadescent halogen 24V DC works for me! Bulbs are like 0,25€. The most pricey is the PSU - roughly ~10€ for a 100W/24V LED PSU. The upside is you can convert any regular AC lamp to DC - just replace the bulb and place the PSU in the circuit between the mains and the lamp. Thanks to DC and lower voltage, not only is the setup more long lasting, the light doesn't present microflicker so many people have eye irritation from. Plus, the scope of the light resembles most that of the sun, which often times cannot be decivesly said about LEDs. It's not that they just produce bad light altogether - it's that there's currently no easy way to test for sure which spectrum of light the commercially available ones produce. And so until there is, and they clearly are marked on the shelves, I rather steer clear of them and keep all their eventual blue light effects away. For those who still do not know about adverse effects of blue spectrum light in 2020, I recommend just a quick Google search - messed up melanoma / sleep cycle production / hastened aging of human body cells etc being the issues mainly discovered and discussed so far, as effects of said blue light exposure. So, DC 24v incadescent halogen.
Melatonin not melanoma, a skin cancer.
LED's are blue light. Blue light in excess and beyond the usage at noon, will through off circadian rythym in the masses, and reduce the efficiency of the mitochondria in cells provided enough exposure.
apparently this is strictly limited to the blue spectrum? So, ridding blue and using violet wavelengths looks like it fixes the issue while attaining high CRI? I haven't seen independent 3rd party analysis on this other than from what the Japanese companies themselves push, but I haven't tried to look very hard, either.
@@androidkenobi I read that masking the bulbs doesn't help much.
I would like it if the places replacing all of the yellow incandescent street lights with LEDs would add a yellow tint, dim them, or do something like that to them because: 1. It hurts my eyes 2. The American Medical Association has warned of issues with the amount of blue light coming from them being bad for our eyes 3. The LED street lights are creating much more light pollution which is bad if you want to see stars and it hurts marine life.
The filament style LED eliminate that problem. I have them on my house for a nice soft glow outside. Turtles actually go towards light, I do not know why.
Those aren't incandescent. Those are high pressure sodium. Without the reflectors and lenses they are more efficient than LEDs.
Very good video getting to see the differences with a watt meter is helpful. I guess I am still old school about energy use. Living in a rural area like I do I know of one example that incandescent's rule. When you have your well house outside you always hang a 100 watt bulb inside to keep the pipes from freezing. Also in the winter when your house is lit up with incandesent's you do get the heat escaping from the bulb into your living space. I would think changing the bulbs in the house to led in the spring / summer months would be ok and changing them back in the fall/winter months to incandescent. The problem I see in banning or not making incandescent is you end up having to come up with some other idea to get the heat/energy you need for whatever purpose rendering less energy use pointless. i am not against the newer technology but you should have a choice in lighting instead of no choice.
But incandecent bulbs are less efficient at heating than just using the heater in the room.
And what is a well house?
@@HappyBeezerStudios A well house is a structure. Usually built with concrete blocks. It houses the spring tank and if you have a water softener that too. Also the line coming in from the well is there also. They are usually 4 to 5 feet deep and have a tilt lid or side access door for service. You normally have to hang a light or heat bulb in there when the winter gets harsh. Usually when you get a constant wind. I usually hang a bulb once the temp gets around 10 deg.
Back when I knew the ban was coming I stocked up on the good lightbulbs. I have enough to last the rest of my life.
O.o
with how long they last i suspect you have a giant room filled to the roof with light bulbs just to last 1 year
@@jimbobbyrnes Not quite that many but more like one shelf of a kitchen cupboard full. Enough to last.
@@checkpointcovid8021 I went to Habitat for Humanity and bought a lot a lot a lot in all my favorite colors and sizes especially the Amber and the hot pink and also some of the red as well as soft pink and the kind that claims to be full spectrum but is not the same as the chromaluxe.... I don't care what anybody says I have the right to have incandescent in my home..... more and more people are complaining to me how much they hate the street lights and how much they hate the lights that are in front of and on the side of the buildings and when they go into the stores . Those shitty LED lights are making a lot of people feel weird and sick
I'm pretty sure that incandescent lights can still be bought normally, as long as they aren't advertised as lights, but heat sources. They still work great in stuff like lava lamps.
If the heat is used in place of a heater then we are not inefficient.
That's true in the winter, but in the summer if you have air conditioning, it will cost you even more to cool your house.
Air conditioning drains power in a way that dwarfs light bulbs.
+Alan Crook because people still build above ground, which is not efficient.
No, because the cost of building anything under ground is 10 times as much as building it above ground
yeah the thought crossed my mind to flip out the CFLs with incandescent every winter however I'm too lazy
You can still buy tungsten filament bulbs from specialist retailers. I bought a pack of 3 100W in London recently, they were old stock. The new ones are more expensive and marked 'industrial use'. They were made in Turkey.
Not banned anymore! 👍🏻
Thank you President Trump!!!!
Biden just banned them again.
@@jfrphoto01 Sadly Biden just banned them again.
LED lights are more efficient in terms of thermal energy inefficiencies but to entice the public the electronics necessary to convert AC line voltages to power the LEDs are very poorly designed as high frequency inverters used create huge amounts of wide band radio noise pollution. Turn on and AM or FM radio and then turn on and LED "replacement" bulb for an incandescent light....it is terrible!!
Cheap electronic designs are causing huge problems and need to be addressed. Then the spectrum of light frequencies for our eyes and those effects - more studies.
More needs to be done to abate these issues but very solvable!!
I agree... there should be a nationwide standard for electromagnetic emissions, while there are not long range, it can ruin a Hi-Fi stereo experience while close by.
another match in this world we live, as no wonder as for sATAN himself disguises himself as an angel of light, new bulbs burn so bright but burn out so fast and make more waste where old bulbs like the cinula bulb and my bathroom bulb burn dim but last for years upon years.
The problem with electricity-related issues, such as 'dirty electricity' etc., will be extremely hard to bring attention to and get addressed because as the saying goes, 'out of sight, out of mind', and electricity is invisible, so...
Wow, first video I saw on your channel and I already subbed! Very informative and thorough. I can say that while this video was educational, it was also not a yawn-fest and was very much a joy to watch. Thank you for your content, you're an excellent cameraman and commentator, I look forward to seeing more of your channel.
Banned incandescents you say?
