I very much like the usual “One moment please” The only one who has to “wait” is the good man himself. For us viewers there’s no wait at all. For Clive there’s no ‘wait’ either as I suspect the photos and reverse engineering don’t just magically appear. Your effort and excellent production quality is very much appreciated!
I used 15 of these in a small raised bed garden that was heavily shaded. The lens fell out of some of them but they still work. 2 years outdoors and quite surprisingly they’re still doing well.
The science behind grow light spectrum selection is a very interesting rabbit hole to fall down. more recent studies I peeked at out of morbid curiosity suggest that broad spectrum is better than 'Burple' because while plants may not use all wavelengths for photosynthesis, they do use other spectra to trigger certain growth factors that indicates things like competition (Shadowing), dawn/dusk (blues/reds) and of course season (UV concentration) There's also the human factor... It's difficult to see issues in the plant such as fungus or damage under Burple!
How serendipitous, I have literally been looking at grow lights today. Not for anything nefarious, I'm getting some seedlings going to give my veg plot a head start in the spring, you've got good timing!
aliexpress (other cheap Chinese outlets exist) round or square 36w led lights that slide on to a contactor as shown here recently are great. MUCH cheaper than grow light when not on offer they are about £10 but on offer can be as low as £5 each with free P&P
I built my own linear grow lights using luxeon star clones thermal-pasted to some leftover aluminimum extrusions and some cheap led drivers. Initially I just did burple ones, but I discovered they kinda hurt my eyes when I'm trying to work on the plants under them, so I added one row of 'broad spectrum' leds just for me. Broad spectrum isn't really for the plants, but a little bit of white or green light mixed in helps the humans.
I'm glad you posted this, I'm going to plant some tomato and chilli seeds soon and you reminded me that I needed to buy a couple of these lamps. I've chosen the burple ones as those colours seem to be best for photosynthesis.
I'm glad you posted this comment 3 weeks ago, despite the video only being out 25 minutes, meaning us regular users don't have a cat in hells chance of buying this at the same price as Clive did, assuming this is even in stock. Which is a shame given that the color looked OK and this also looks like the style of a UFO Frisbee object!
Just a minor correctioni: 5000K isn't cold white. It's about as close to neutral white as an LED can get as it's approximately the standard photographic white point. Cold white tends to be more up around the 6000 to 6500K range and has a distinct bluish hue to it.
5000K can come off as extremely cold if they skimped on the phosphors in the red to yellow part of the spectrum, which a lot of low CRI lights do. Part of the problem with fluorescent tubes was that they had similarly rubbish CRI, which is why paint swath desks used to have buttons for incandescent, fluorescent, and "daylight" (the last one was just both lights), and a lot of the early "daylight" LED bulbs had the same problem. Fortunately, high CRI phosphor blends are more common now, but I wouldn't be surprised if LEDs with the more rubbish blends are being liquidated in fittings such as this, because the warm white phosphors help fill in the gaps. Also, I promised myself that I wouldn't get into the pedantics of higher color temperatures being "colder," but I guess I just broke that promise, so in a nutshell, the hotter a star's photosphere, the bluer its light.
@@thomasneal9291 No, not all 5K are created equal. I remember having one of the earlier "daylight" bulbs in my bathroom that made my pale-ruddy skin (typical for a ginger) look ashen because of gaps in its emission spectrum.
That's a very aesthetically - nice light! It would be pretty good for even general lighting purposes, however it's probably great for getting seedlings going in the winter and early spring months. This sort of thing would have been a godsend back in the day when I lived in the UK, with my 10' x 8' greenhouse and "significant" gardening hobby
Super interesting Big Clive. Thanks. Not bad for less than six bucks. I like the color. I've got a High Bay light for my ficus in the living room. It has a dimmer that I can dim down - currently at 40 watts / 117 volts. I could put four of these up for greater coverage and maybe spectrum.
2:54 thanks clive for the fuzz test. i've gotten that from a LOT of electronics over the years and others have said they feel nothing, lately from a set of large grow lights and my bro feels nothing. i'm not insane yay (at least for that)
I only buy 4000K cool white and 6500K daylight bulbs. IMO 2700K and 3000K is too yellow for my liking, so I for one agree with the Chinese way of marking warm white as yellow.
@@Nono-hk3is wait until you see first Gen external phosfor 2700k Phillips bulbs, if i had the money i would buy one for Clive to tear down, it has an egg yolk inside a translucent white diffuser dome over Royal Blue LEDs, i should buy some while they still exist lol
I grow 'herbs' inside. I prefer to use the normal LED bulbs you can get at any hardware store in the daylight and warm spectrums. Then, when they get bigger, I prefer to use a 600w high-pressure sodium lamp and ballast. Works great ;)
Merry Christmas Clive. Hope all your packages arrive on time and in good condition. This light would make a nice "outside" temperate zone area light for a small location, say a corner or alcove. Not sure of its abilities to actually grow anything but the color is nice. Thanks for the tear down and explanation.
It was certainly how I got my start! Not sure my brother appreciated me stripping his bike down to the individual ball bearings at the time, mind you...
I found out myself a long time ago that fondling the metal casing of an electrical device with the back side of the fingers very often gives this slight tingly sensation if it is "grounded" by the tiny HV capacitors... if it is floating, usually not so much. It even seems to impart a slight friction.
Apropos lamps: It might be interesting if you took a look at those newfangled LED lamps that have the (new) EU energy rating "A" (or better). Supposedly they last a lot longer and are more efficient. But are they really? Is it an alternative to the Dubai lamps? Or are they still grilling the LEDs, just more efficiently? Just a random thought.
The capacitive coupling is crazy with these cheap led drivers, one particular brand of cabinets likes to glue the metal cased 80w led drivers to a metal backplate, of course they dont come with an earth wire. When you touch a screwdriver to short it makes almost a continuous spark
A test in 2016 which I cannot find any longer showed what happened at different wavelwngts. Red having less energetic photons made the plants larger, while blue kept them compact. I suspect most will be best served with normal white light with some separate blue and red COBs. You can go into absorption equations the different chlorophyle types but the sun does not care.
I still run a 1000w metal halide and a 1000w hps. I have friends that get good grows out of leds but I say there’s no replacement for displacement lol 😊
My friend managed to get his hands on a bunch of tobacco rustica seeds and will be starting them in March they are in the refrigerator right now .He picked up an LED light and starting tray at Costco .Wonder if setting one of these up on cord tails would work at a fraction of the price just over a 24 inch diameter pot .Wonder what the height would be over the soil for best results
Pretty good broad spectrum mix for a cheapo shock hazard light. That said if one really wants to grow anything with screw in lights I'd recommend whatever the cheapest 1500 lumen general purpose bulbs you can find in whatever quantity is necessary.
I got about 300 watts of t5 aquarium lights in a clearance sale, for 20% of the original price. Im going to get some seedlings going on a couple of garden centre style trolleys with adjustable shelves.
7:43"Let's open this little Christmas package"....it's been far too long since I got a nice package (big or little) for Christmas. 😮😅 This was another great teardown of terrifying tat, thanks for doing it. Merry Christmas to our favorite Manx bear!❤😊
Love that you clarified the earth symbols, ground as a convention in electronics is confusing, it being named 0 potential is more intuitive, personally i blame the yanks they love a good ground.
I have a couple of older, professional LED grow lights that I would love for you to dig in to. Trouble is, I am in the US and they weigh a couple kilos together. They're all metal construction with screw assembly. One is a blue light for vegetative growth and the other is a darker fall color for flowering. I've grown a fair number of products with them. I fed a couple of rabbits lettuce and other veg for a couple of years - all grown in a tent.
Made my own grow lights for my winter garden plants (Citrus × limon and Nerium oleander) with those pinky cheap DIY 3W star shaped chips "380nm-840nm". They work fine and my plants seem to like them (last winter no problems). Put a bunch of them on alu heatsink-leftovers from no-idea-what combined with an older MeanWell power supply.
Little gadget that you might appreciate - OPPLE Light Master It measures the light Illuminance,Color temperature(CCT), CRI, CS, EML, R1- R14, DUV via bluetooth on your phone - ive been using mine for about a year and has been accurate - plus its about $30-40 from the usual sources
Interesting video, (I thought it was a shower head for a moment!) But what happens to all the bits at the end. Do you re-wire it all back together? (Someone would buy it, especially if its been on Clive's bench.) Or does it go into the skip...? 🤔
I got a set of lights on Amazon a few months ago that looks identical to those lights with string plugs. The listing was called: "Yidasyn Outdoor Grow Lights for Outdoor Plants Waterproof, Full Spectrum, 22FT Adjustable Cord, Daisy-Chain String Grow Lights for Seedling,Veg,Flower in Greenhouse Garden Backyard Farm(6 Lights) "
Looks like Clive is buying lighting in order to grow his Herb of choice.🌿🤔Nice move.👍🏼 Not sure if a Chinese light is going to last long enough to complete the process.😱
3:01 Is that what that is? I’ve been wondering for ages why I get a slight tingle that makes the hairs on my hand stand up when I touch the metal case of the (unearthed) DVD player!
It's very common and quite an annoying feature of the modern high frequency power supplies. Not just capacitive coupling between the winding layers, but also via the capacitor that is supposed to provide a route back for that coupling to reduce the radiated electrical noise.
Thinking how much money I spent and effort to control heat in the old days of using ballast driven halide and sodium lamps to do closet grows. When LED lamps came out, so many problems with heat disappeared but it meant buying all new equipment and it wasn't cheap like now. Of course, it's not illegal to buy swhank now, so there's little profit in closet grows. But I'd have given a nut to have a lamp like the one you're showing.
Standard switch mode type power supply, they can usually handle 85-270V. The simple version: first they convert to DC, then switch the DC on and off at high frequency (for efficiency). The ratio of "on time" to "off time" determines the output so if the input voltage is halved the on-off ratio needs to be doubled to achieve the same output (approximately).
2:44 my phone is giving me tingles when I slide my fingers over it and when the phone is connected to a charger. *Well not exactly tingles* but I feel a slight fuzz similar to when you touch a CRT but weaker. I can even light up my test screwdriver a bit when I touch the metal body of the phone. But I guess that is fine.
Anything better for starting chili plants from seed during the winter months? I have some demon red seeds that grow a lot of sub 1" chillies on a compact plant. Sadly I left them on the window sill not realising how cold it was behind the curtains at night. Looking for something safe to leave on for extended periods, ideally DC not AC. Only small plants so no need for a grow farm worth of lights.
I'm commenting early, but wondering. Plants only need the red and blue parts of the spectrum to grow, which is why LED grow lights are now purplish in color. So why the full-spectrum "grow" light? Just curious. I shall continue watching.
The little blurple B&Q propegator USB LEDs are cool Only £2.99 They look like little space ships And make a great 3D effect with Shadows being outlined 3 times Black outline, red & blue outline... Never tried viewing thru 3D glasses tho
Nice video, Clive, and an interesting lamp. I wonder how safe the light output would be for humans, although with no UV LEDs it would likely be safe for humans. I'm not into growing things and don't know what kind of light spectrum is good for what. Maybe a grow light comparison would be interesting? I did note that when looking at the physical circuit board you described an inrush limiter being present, yet on the circuit diagram you drew out there was a surge suppressor across the mains input rather than an inrush limiter in series with it. Which is correct? Is it an inrush limiter or a surge suppressor?
Same to British customers. It might be some sort of new customer incentive: existing customers pay more. You see something you like, log in and find the price has substantially increased. :-(
Don't plants pretty much just respond to the sort of rwd and blue combination though, the warm white one might be ok for cress... Or mould 😂 but beyond that, it's a light populated by the wrong colour leds for my liking
I build my lights with only warm white LED COBs. Seems to work just fine, my cannabis plants grow big and strong. The 100w COBs and drivers are very cheap to buy compared to any legitimate grow light with comparable output.
Mixing 3000 K and 5000 K white light doesn't give you better color or a more even spectrum. It just gives you a shade of white in between, which is 3750 K, assuming equal luminosities. It would also have a slight magenta tint, being off the black body locus, so it's not even pure white. There's no particular benefit to mixing whites like this in a fixed ratio. You'd be better off using emitters of the desired color temperature. Now if the ratio could be adjusted, then it would be a tunable color temperature, which is quite useful.
I dont care how many lights you buy, you are not going to grow any taller 🤣 Interesting light be even more interesting with the housing referenced to ground. 2x👍
Thanks. I’d think that would also make a great video, explaining how to mix the various different LED types. Especially since this would also include the wavelengths not visible to the human eye, most (all?) “daylight lamps” ignore those.
heh my stepfather accidentally ordered a burple lamp when just browsing amazon, it has a bracket/cord instead of edison base but looks nearly identical to the reflector, never seen a grow light with UV and IR before!!
The main features are: poor current balancing, poor heat sinking, token numbers of UV and infrared LEDs and of course, a power supply flailing on wires. It's essentially a reading light with a few oddball emissions. Don"t buy one but if you were forced to use one, it would be good to attach an earth ground lead to the aluminum housing to provide a modicum of fire and shock prevention.
Patreon is the best, since it does allow me to share videos before release. I don't use TH-cam's membership system as it risks that if they pull the plug on my channel for being "dangerous" I lose everything.
I use YT's "Super Thanks" to send him some elusive spondulix around Xmas/New Year's but they take out 10% GST. Not sure if that entirely legal for a donation. One day I'll ring the ATO (Aust. Tax Office) and ask about it.

A mix of warm white and cold white fluorescent tubes work very well for your needs. LED grow lights alone are a bit narrow band for seedlings.
What would a nefarious use for a grow light be? 🤣

@@TheSpotify95
Just out of curiosity: Do you use 6500k lights for example in your living room in the evening?
It's due to 100,000+ years of being around camp fires in the dark. We like warm white because it's safety.

Haha "store room" - if Clive is anything like me, the store room is a giant, unstable mountain of tat just out of shot on every available surface :D
Got the same lamp but without the glass. Seems like they’ve stepped up their game.
That's probably because the LEDs on the front of yours may be live with respect to ground.

Very interesting, particularly for the price, even though it was a Black Friday price and should be now doubled.
Just checked and still around the same price.
Then it gets mildly moist and goes bang, cos I remember a similar light you took to bits some years ago having had a case of death by wetness... :P
whats the point in have IR in a grow light? or anything with longer wavelength than green, the colour of leaves, for that matter?

If it's a good quality charger from a reputable source, then it should be OK.
Nice.
Love to see you do a guitar looper pedal.
UV LED and IR Led does not effect photosynthesis. Both wavelenghts are trigger anthocyanin bio synthesis.
Anything better for starting chili plants from seed during the winter months? I have some demon red seeds that grow a lot of sub 1" chillies on a compact plant. Sadly I left them on the window sill not realising how cold it was behind the curtains at night. Looking for something safe to leave on for extended periods, ideally DC not AC. Only small plants so no need for a grow farm worth of lights.
I'm not sure what level of light chillies need.
Non isolating PSU + metal housing = "should be grounded" IMHO. Thanks for the heads up!
Not so easy with a bulb/lamp.
Did I miss something? What happened to the proper HOPI?
It's fine. This one has a better resolution for lower loads and ultra bad power factors.
The bezel might be wide enough for a ceiling can to look okay.
I'm commenting early, but wondering. Plants only need the red and blue parts of the spectrum to grow, which is why LED grow lights are now purplish in color. So why the full-spectrum "grow" light? Just curious. I shall continue watching.
The little blurple B&Q propegator USB LEDs are cool
Only £2.99
They look like little space ships
And make a great 3D effect with Shadows being outlined 3 times
Black outline, red & blue outline...
Never tried viewing thru 3D glasses tho
Nice video, Clive, and an interesting lamp. I wonder how safe the light output would be for humans, although with no UV LEDs it would likely be safe for humans. I'm not into growing things and don't know what kind of light spectrum is good for what. Maybe a grow light comparison would be interesting?
I did note that when looking at the physical circuit board you described an inrush limiter being present, yet on the circuit diagram you drew out there was a surge suppressor across the mains input rather than an inrush limiter in series with it. Which is correct? Is it an inrush limiter or a surge suppressor?
It's a MOV surge arrester.
the light output is safe for humans, but not the housing.
AliX Australia: Before logging in: $1.68 free freight. After logging in: $9.89 plus $15 freight!
That's excessive. Probably caused by local politics.
Same to British customers. It might be some sort of new customer incentive: existing customers pay more. You see something you like, log in and find the price has substantially increased. :-(
Don't plants pretty much just respond to the sort of rwd and blue combination though, the warm white one might be ok for cress... Or mould 😂 but beyond that, it's a light populated by the wrong colour leds for my liking
I build my lights with only warm white LED COBs. Seems to work just fine, my cannabis plants grow big and strong. The 100w COBs and drivers are very cheap to buy compared to any legitimate grow light with comparable output.
Mixing 3000 K and 5000 K white light doesn't give you better color or a more even spectrum. It just gives you a shade of white in between, which is 3750 K, assuming equal luminosities. It would also have a slight magenta tint, being off the black body locus, so it's not even pure white. There's no particular benefit to mixing whites like this in a fixed ratio. You'd be better off using emitters of the desired color temperature. Now if the ratio could be adjusted, then it would be a tunable color temperature, which is quite useful.
Orange capacitors! Well, that's exciting.
Even my high end Belkin charger still has a noticeable tingle on the back of my iPad
"Many people call burple" The way you said burple in your scottish accent made me laugh. hahaha!
I feel like this could be useful for more than just growing jazz cabbage, nice colour
LOL "Jazz cabbage" Is that related to 'Devil's Lettuce'?? 😉
Keep this up and you will 'need' a spectrometer (Cheap USB one will do ) because you can't be sure the wavelength details are correct.
I dont care how many lights you buy, you are not going to grow any taller 🤣
Interesting light be even more interesting with the housing referenced to ground. 2x👍
What’s the most energy-efficient way to create a lamp that really has the entire spectrum of ground-level sunlight, from UV to IR?
That could be a mixture of lamps.
Thanks. I’d think that would also make a great video, explaining how to mix the various different LED types. Especially since this would also include the wavelengths not visible to the human eye, most (all?) “daylight lamps” ignore those.
I have an amazon one. On the thermal camera it hits over one hundred degrees centigrade!!!!
Could you please leave a link to this product? Would be nice to use these for indoor lighting
Here's a link. vi.aliexpress.com/item/1005006931284494.html
No guarantee of safety or lifespan.
Measured lumen output? Spectral analysis? How do we know this lamp is doing what it says on the box, given the source?
That would need specialist test equipment.
Clive, do you think this would be "skin/eye safe" as a SAD (seasonal affective disorder) light?
It could help, but could be ordinary lights.
We need a new let's build video. My ghost detector is getting lonely on the windowsill above the work bench.
The UV/IR are just there to bring up the µmol/W for marketing purposes. They don't really do much for plants.
YOU LEGEND!
heh my stepfather accidentally ordered a burple lamp when just browsing amazon, it has a bracket/cord instead of edison base but looks nearly identical to the reflector, never seen a grow light with UV and IR before!!
I think you miss Hopi a lot, because you used Antai and said "Let me grab Hopi"😃
The main features are: poor current balancing, poor heat sinking, token numbers of UV and infrared LEDs and of course, a power supply flailing on wires. It's essentially a reading light with a few oddball emissions.
Don"t buy one but if you were forced to use one, it would be good to attach an earth ground lead to the aluminum housing to provide a modicum of fire and shock prevention.
Do you think the insulation around the PSU is sufficient, given there is a metal shade?
I don't trust the insulation of any of these metal cased lamps. I recommend not touching them while powered.
Clive, do you offer ways different from Patreon to become a supporter of your channel?
Patreon is the best, since it does allow me to share videos before release. I don't use TH-cam's membership system as it risks that if they pull the plug on my channel for being "dangerous" I lose everything.
Thanks for answering, Clive. If I am leaving your supporter crew it is never about you and your videos, but the way Patreon is acting. Sorry ...
@@peter.stimpel Patreon is definitely capable of improvement.
I use YT's "Super Thanks" to send him some elusive spondulix around Xmas/New Year's but they take out 10% GST. Not sure if that entirely legal for a donation. One day I'll ring the ATO (Aust. Tax Office) and ask about it.
Hm, OK. I was looking for something more regular, repeating, automatic.
grow lights heck yeah
Can this be used as a daylight lamp? I spend 12 hours a day on the computer...
It might be useful for that.
Thanks :)
