This is NOT A POLITICAL VIDEO!!! I'm a simple man...
Also regarding Halogen light bulbs, it seems in countries with 240VAC they are designed such that their life is same or better than incandescent. In 120V of north America almost all I can see for halogen is half the life of incandescent for same power rating (make sure lamps run on same voltage and light output when comparing). In any case, I filled my table per my local values for my lamps, and some per my taste. you can always adjust the table values to your local numbers and taste and recalculate. LED still will get top point. and who cares if halogen scores a bit higher WHEN LED IS WAY HIGHER ANYWAY! and remember... THIS IS NOT A POLITICAL VIDEO!

The glass you broke on halogen is not for aesthetics only. Halogen bulbs have a tiny possibility of violently exploding. That's why every halogen lightbulb has double glass. In case of floodlights and car lamps, the second glass is part of the lamp. Spotlights, 'power saving' lightbulbs, etc. are double glassed for more than aesthetics.
You’ve a point; that halogen bulb should have gone off like a hand grenade when he shattered it!
@@chrismayer3919it doesn't work like that. I've broken loads of them in different ways, including shooting at them with pellets
I've been using LEDs for the last 14 years (the first were ceiling lights) and what I find incredible is that those 14-year-old bulbs are still going!
I didn’t know the LED bulbs existed 14 years ago. Also the 14 year old LEDs are probably dimmer than the new ones.
they will stay strong for a decade more if you are careful with thrm
And you can easily repair LED lights if you know about electronics. You have to just replace an led in some cases which only costs like 1 cent.

LED lights vary in lifespan too. Most LED "bulbs" overdrive the LEDs, making them heat up, reducing efficiency and lifespan. Underdriven LEDs, say doubling the number of LEDs for the same output, will use less electricity and last longer
Thanks for the normalized table which confirms my growing esteem for LED bulbs. Memo: In a microwave oven, only incandescent should be used for the CAVITY lightbulb (an LED will quickly fry). For an over-the-range nuke, LED bulbs work great on the underside for range/countertop illumination.
I've been lucky with all the microwaves I've put LEDs in. From my observation most bulbs are installed outside of the active area of the megnetron, separated by a mesh then encapsulated with sheet metal to manage RF emissions. Though I imagine some microwaves will have the bulb inside the active area to save on manufacturing costs (I imagine putting the bulb inside the wave guide behind the plastic sheet)
6:40 it's always a surprise when the stuff doesn't explode when he plucks it in

Yanko024 who asked 🗿
I always brace for it lol.
18 years ago I replaced all the incandescent bulbs in the house I had just moved into with CFLs. After *nearly two decades* they're finally starting to wear out. Safe to say I got my money's worth out of them, and saved a boatload on my power bill. They served their purpose, but about 1/3 of my house now uses LEDs and that number will grow as the CFLs gradually fail. I swapped my truck's headlights for LEDs too and love them.
I will say that I haven't found a "warm" LED that comes anywhere close to the color temperature of an incandescent or CFL. Admittedly I haven't bought a bunch of them to compare, but both brands I have tried skewed more brown than orange/yellow.
you just explained to me exactly why I hated fluorescent lights, the light always looked wrong and hollow to me... for years I stuck with incandescent because it just looked real. I swapped to LED, and found that some LED lights irritated me due to the pulsing nature of their light, I used a 1k fps camera to catch it, but the light wasn't steady on but rather ran at around 60hz (coincidence maybe?) My favorites are the ones I constructed myself on DC circuits to avoid the flicker factor that some LED bulbs once had
"If everyone looks different then no one looks different."
-Mehdi Sadaghdar, 2020.
What even suppose to mean
@@abbaseldor6532 I seriously can't believe I have to explain this to you. If everyone looks different from one another, everyone becomes equal again, because there are no groups of people that look the same. If every human was a different color, there wouldn't be color based discrimination, because everyone is a different color to begin with.
If everyone is a super, nobody is a super.
@@Da-Creams now i got it.. Thanks
@@Da-Creams True it logicly valid
Two annoying qualities of CFL you forgot:
* Heat up time to reach full power is now better than years ago but still there
* CFL lights will decrease in life span tremendously when switched on and off frequently.
And something else that was mentioned but glossed over is the cost to dispose.
And for LED: the low cost driver circuit limits the LED lifespan significantly.
fyi cfl light's lifespan will increase dramatically if you use a ballast and a starter rather than an automatic one.
And something else I wanted to mention: you can dimm the Halogen lamps but it shortens it's life significantly (and also if you start to run then at low voltage [at least lower than what they intended to] they could have dark spots on them so I wouldn't say they are dimmable.)
I have several CFL lights that come on at full brightness. Only when I got some more did I discover what everyone was talking about with the warm up time. They must be using something that costs more than mercury. Otherwise why would any maker still make ones that are slow.
9:58 - Thank you for including my national anthem. Warms the heart on this cold autumn day
I'm surprised you didn't mention the CRI scale, or color rendering index. It's super important when buying LEDs. I'd love to see the difference your spectrometer shows between an 80 CRI LED and a 97.

As an electrician who specializes in lighting controls, I am in love with the Ikea spectrum!
You into DALI lightning controll? Thats a really good interface over BUS-communication. So you want light switches near the sinc? no problemo just run like a 12V powersupply and no fancy isolated switch is needed. Need 30 swithes with dimming for one light? comming right up sir. DALI has so much feutures and is so intuitive to use.
Led is best
@@rub3n0st DALI vs KNX, go go go
@@ishzarkklyon9590 seems like KNX is more advanced as in you can do more with it? It has som really cool features that i don't think DALI has. But for lighting controll, and not a smart home the DALI-Cockpit seems like a better solution for me.
I have been watching his wonderful videos for a long time, and I think this is the first I have seen where nothing blew up.
incandescent or halogen have their uses still for some applications , in some cases necessary such as oven lights, also very useful as current limiters in resurrecting old radios, tvs, etc.
I have bought a halogen lamp especially for testing astronomical filters. Together with a very inexpensive (7.90 €) hand spectroscope, the spectral transmission ranges can be easily estimated. Halogen is hotter than other incandescent lighting, giving more intensity at shorter wavelengths.
"So because he's orange, he looks orange."
"It's not about if I dislike the president or not like him."
"Enough talking. Let's talk some more..."
This video is fantastic. Today I am happy to be a patron.
remember when the guy at msnbc got fired because he used an orange filter over a broadcast, and they compared the actual image of trump verses the orange filter trump side by side?
The ironic thing to me is that the old, incandescent lighting would make everyone look more orange.
TheDamped like really
@@commentfreely5443 Nope.
... continued:
It seems the screen sent this message before it was completed (I ave a physical coordination difficulty that likely was the cause oif this).
2) CFL and fluorescent: I don't like there either. they were an improvement over incandescent and quartz halogen, but they have had theor time. LED lighting has come down to a reasonable price so I am phasing out the others, although I might use the occasional incandescent light as a dummy load in electronic experiments, but that is out if the real scope here.
Also, LED's can be used without the need of class 1 wiring, i/.e. the basic electronic component with an appropriate ballasting which can operate easily with as little as 5 volts D.C. which at times can serve to avoid dangerous voltage in some places whewre that is particularly important and/or convenient.
(But perhaps Mr Trump likes to 'trumpet") so let him trumpet but the value of said "trumpeting" in in the ears of the audience, so let the audoence wrorry aout "keeping politics politik" rat er than seeking to "out trumpet Mr. Trump"
Americans elected him, let Americans deal with the consequences, as time will tell. But also let us all respect that The president, the person, is very distinct from POTUS .(American acronym for "the President of the United States)
End of "comment of politik"!
Now let's thinlk some more everywhere about "let there be light", and those led's which are encased in plastic. They won't give you mercury poisoning and you can have them in many colours, but wen used, do recycle as the electronice in the light bulbs made of them do contain elements that should not go to landfill, so leaving those who don't "green" with envy at our improvements.

The thing about the blue light is so true! I HATE modern car headlamps with that excessively bright blue light. Paired with the painfully slow auto dim of many reputable brands it makes it almost impossible to see after some of these pass in the opposite direction.

I would love to know your opinion on how much color temperature of light affects your mood and energy levels. I found these awesome color and temperature adjustable smart bulbs at a liquidation store I have been using for many years now, and I have Google home routines set up so that in the morning the lights turn on with an even WHITE color (Red+Blue) to help you feel energized and refreshed, and more like natural light outside, and then in the evening at sunset, the lights will dim to 30% and move to a much warmer tone to help you feel relaxed and give you that nice warm light. I think it's a killer setup, and I have noticed in myself that with the white light during the day I feel more awake and alert vs when I used to just have normal warm light inside all the time.
Love your videos man, been watching for years and years, keep up the fantastic work and fighting the good fight to keep people well informed on important information like this. Cheers mate!

It's ridiculous how difficult it is to break some of the LED bulbs. I was hitting one much harder than that, it still didn't break.
@@PistonAvatarGuy also breaking that doesn't mean light stops working like other bulbs.
@@JJayzX Correct and they're usually repairable when they've stopped working. I was able to repair that light and I still use it (without the cover).
“Go warm or go home” - Mehdi 2020
O hate warm light. lol
Great video, thank you for this comparison. LED is indeed the lamp of the future. However... power supplies in LEDs differ a lot. That's why some of them are dimmable and others not. What you forgot in my opinion is the power-factor. Especially in LED-land there are a lot with a very bad PF, even way below 0.5. The simple capacitive droppers are the worst. This becomes a waste in countries where people and especially factories are starting to pay for VA instead of Watts (thanks to smart meters).
capacitive droppers are better in a way as less to go wrong in them ,
He also forgot about Color Rendering Index. It is very important!
for a normal person or hobbyist like me with no electronic background iv been able to find ways to diagnose and fix most of the household electronics or electrical problems but its quite a necessity for a person to be able to understand a little beyond the basics fix to things around the house or ger things done creatively your way and thats when you realise the broad complexity represented and the frustration that arises while learning,i personally seriously cant keep up for long with serious,boring lectures about values and numbers or equations and formulas when your end goal is fixed on household,to make matters worst the amount of misleading or inaccurate content vs legit ones are overwhelming..

@ElectroBoom Hi, the spectrums you showed between 5:50 and 9:40 are the raw sensor outputs.

I guess you would be glad to know, when I moved into my current home, I replaced all CFLS, tube fluorescents and incandescent lights, with LEDs.
I also replaced all lamps, outdoor lights, my fridge light, stove light and so on, with LEDs.
The only lights I didn't switch to LED, were my oven and my microwave.
I don't know what my modern microwave uses, but I'm pretty sure I can't use an LED in my oven.
However, I would love for them to come out with a better option that makes LED look at bad as incandescent light.
The only thing I like about CFLs, is being able to salvage the toroid magnet.
The only thing I like about incandescent, is using them as a cheap heater that puts out light (but I have no need for heaters).
7:01 And that's another disadvantage of incandescent lights. They get dangerously hot.
ElectroBOOM really seems to like LEDs and hate Incandescent bulbs.
GOOD.
damn canada is flooded with led lights
*G O O D*
There is no reason to dislike Incandescent bulbs in Canada. The color looks good. It is energy efficient in winter which basically lasts 8 months. Most of the power is consumed by the water heater and refrigerator and the heating elements of the house. In comparison to heating a house, the power consumption of a Incandescent bulb is nothing.
@@louistournas120 But if you were running off a battery pack, you would want efficiency, and incandescent is the least efficient you can get. You can get an LED bulb that creates the equivalent light for 1/6 the energy cost. If you are generating your own energy, this is significant.

honestly, you're doing an amazing job at telling people how they are wrong. honestly, the required spectrum (and frequency) of a light source _will_ determine the type of source being used. you just need a desktop lamp to read some papers? use LED. need to do stuff in a workshop with rotating machinery (more or less in sync with the network frequency)? use incandescent or LED or a combination of all these ; even FLs on all three phases will be confusing. Need to do some painting or work with tiny electronic components? Then you need a smooth, well-distributed spectrum. Need some lighting in a bathroom, that also needs some IR so it feels warm? Then you can either chose LEDs and add some IR heating to complement them, or instead just use standard filament or halogen bulbs, as these might just radiate the right amount of heat and light to suit your use.
There is no "right light source" for any use, it really depends on the use and in what conditions things are being used. Making things such as incandescent lights unlawful will not save the world ; people need to be taught to use the correct device for the intended purpose.

In both situations, the established/existing light companies fought tooth and nail to hold back the new technology. And people are impressionable/bribable.

They had valid reason to at the time, this isn't an argument, when technology is premature it is premature.

While 60 watt equivalents are decent now with LED, 100 watts are still fast burn out junk, and neither have economical 100 cri equivalents yet in fact no where near 100 for the sale priced junk. The people who complain about people not using leds are the same ones who go on plane trips to prove how worldly they are, a single trip is likely dwarfs the ecological costs of not replacing every bulb with led, and that's without looking at the hidden ecological costs enabled by these things being made in china..

I can sense the fear in your eyes as you almost dropped that bulb.
I have two situations where I use cold lights: in my bathroom mirror and as optional lighting of my workbench. Both of them have same reason, in more cold light it is easier to see details
Never really stopped to consider how spikes in the visible spectrum blend to us, but don't reflect the same way as a more evenly distributed mix of wavelengths. The differences in how we perceive light and sound waves is so damn interesting, the way our brain fools us into looping the color spectrum with purple, the way most of us are so much more particular when it comes to detecting simple ratios between sound wavelengths vs. light wavelengths etc.
2:03 i am dying of laughter
I laughed hard at 1:53
😂😂Did you spasm like though??
i am gonna make a 10 hour version of it
I laugh the hell out of it and spasmed the like while laughing. I think Mehdi did it on pourpose.

ENOUGH TALKING!!!
Let's talk some more.....
Me: Fell of my chair
Lol I'm now dying
Hi
The only down side with LED is that they are damaged easily by fluctuating voltage
I am disappointed that it took me so long to discover your channel, but I'm so happy I did. Better late than never.
4:16 The person sleeping is himself...🤣🤣🤣(top left)
I can’t stop laughing every time he says “good!”
He sounds a bit like former governor of California (the that used to be an actor or something) when he says that :)
Hi Mahdi, about the light temperature there is more to it that what you said, the warm color(2700K) won't interfere with your sleeping cycle much, but the daylight color(6500K) temperature makes you awake and increases your focus, so if you read before bed, you should use warm but for example in a library you should use daylight for better focus, but warm is not good for designers and artists who need to see the right colors, the daylight temp would show the more accurate colors.
Thanks, really made my day, I'm enjoying the science to humor ratio. I also dig the project comp!etion music. Quite entertaining, cool videos.
"Enough talking. Let's talk some more..."

My family keeps looking at me strangly because I've been unscrewing lightbulbs and looking at them for the past 50 minutes.
This is me
There are still LED bulbs sold out there that flicker horribly. It is especially visible when recording video. It should have been considered in the comparison.
So THAT’S why I needed to wear sunglasses inside my school. Damn fluorescent UV rays…
That or it's to normalize vampirism.
"If someone talks about electrify I have to 'rectify' it"
hahaha.
Mehdi is the type of guy who talks about all of the light bulbs quirks and features and then gives them a Doug Score.

Aaah glad to see a car enthusiasts here . You've got good taste in science and car videos 👌😂🤷🏼♂️
I wish I could like this video 100 times over and then come back a few years later and do it again
Great video as always, but: since when are halogens inert gasses?
Spoiler alert: not one thing blows up in this video.
Oh ok lol
but you can grow weed with incandescent
2:01 "Involuntary muscle twitch"
Wtf why am i here for then
ok but we can make the video blow up by sharing it

Add a row on your table : easy to recycle ... the recycling process in factories
This needs to be adjusted by expected lifetime. A properly designed LED light lasts 30 years.
You could probably reduce the amount of plastic on LED "globes", or heck even use paper to spread the light. I would say that glass could still a lot worse if its in terms of the overall environmental impact. But truth to be told, both are just as bad if you don't take into account the environmental/repurposing factors in production.
EDIT: Though I'm sure that LED bulb waste would drop super significantly we standardised to a simpler way of replacing just the LED part, reusing the housing...
@@UltimatePwnageNL That's theoretical. Actual lifetimes vary wildly. Also there should be a row for brightness and color change over lifetime.
That's not consumer experience.
I hope that led modules become repairable and that we start using recyclable/replaceable cardboard or paper diffusers, if all that needed to be recycled was a small led module instead of a module, driver circuit and diffuser it would be a lot better!
This video definitely saved me when I was doing my T-level engineering exam.
Right in the middle of the paper, we were asked to write an entire page on lightbulbs and their socioeconomic impact on Britain through the 1900s or something like that (which doesn't really belong in an engineering paper), and this video was playing over and over in my head the whole time
I teach middle school science and I used this video in my 7th grade class today.
