126 LED hydroponic death lamp.

- This fairly common red/blue grow lamp has a rather pleasing array of 126 LEDs arranged as 90 red with a star of 36 blue.
Hyped power is 15W. Measured power is 5.5W. Actual power dissipated in LED panel is 5W.
Lamp uses a switching buck regulator that puts out 50V at 100mA and does NOT have an isolated output.
All solder joints on the front of the PCB should be treated as being at full mains voltage. This doesn't seem like a very good idea for a grow light, as the plants will naturally grow towards the lamp and if a juicy shoot or stem touches any metal, then the whole plant will become live.
Chinese safety certification - it doesn't explode after plugging in = PASS
+Adam Dąbrowski They have new standards now... 100 operating hours before somebody has a 50% chance of being killed. Previously it was 50 hours. ;)
+Adam Dąbrowski You DO know the CE certification means "Can Electrocute". lol
Quantum Leap certain electrocution or chinese export
Everything no killing us make us stronger ...
If it's not blowing up it's good enough for me
I thought the whole point of a grow light was to make your plants live ;)
Think the idea is to smoke em
This lamp will make it live once it grows high enough

Son, ya don't grow weed with this. YA FKN SMOKE IT!
Big Clive, you have a fantastic voice. Your accent and humorous tone are a delightful combination. My father was an electronics engineer and when I was young he bought me simple electronics kits from Tandy and tried to teach me how to solder (an unusual skill to impart to a teenage girl but it has come in useful on occasion!), alas I've forgotten most of what he taught me but your channel makes me feel warmly nostalgic. Thank you!
😃😃
+jzknuckles Yeah he is Posh Scotch - only the best from Scotland!
Sounds a bit like Bryce Curdy except he doesnt have a cucumber shoved up his butt!
lol
PS. Bryce Curdy was a gay STV news presenter who turned up at a local Glasgow hospital with a cucumber lodged in his rectum - his career after that was all too short unlike the cucumber which according to my pals at the Viccy was a massive 16 incher! lol
***** I was being fascetious with the last comment - notice the lol i should have put a smiley but its a true story! It was a six incher that disappeared up his bum never to see the light of day until the surgeon removed it with his forceps! I just added a 1 for dramatic effect and you fell for it! >;o)
***** I saw a documentary on the tv where a criminal on Rikers Island actually managed to get a revolver pistol up his butt and smuggled it into the jail with him. I also saw a porn clip with a guy pulling a massive salmon out of a girls bumhole. Nasty!
Pardon me if i sound a bit anal - lol
NEVER as in ever ever ever?
Gosh I am ashamed of myself.

Amazing they let you do this from your Jail Cell.
The prisons are much more relaxed now. I have a full workshop here and teach the other inmates how to circumvent security systems and cause disruption of electrical systems. We also grow cannabis and distill vodka.
+bigclivedotcom youre in jail?
+Nicholas Ruiz Yes. I was jailed for mis-wiring an orphanage and killing all its occupants with electricity.
bigclivedotcom D,:
+bigclivedotcom lol.
"Weed dealer found dead in grow room, foul play suspected, eventually proven to be zapped by an ELECTRIFIED PLANT" would be an amazing episode of CSI.
"hydroponic death lamp" Weren't they on John Peel once?
Martin King Far, far too few people appreciated this joke.
I hear they're doing a set on 6 music next week
I have their first album.
if the plants become live you may be dealing with a day of the triffids scenario! :0
Most of the LED grow lights will state x watts equivalent. What they like to compare to is HID grow lights which are very energy intensive.
About arranging the 21 per sector (around 1:50): If you look at it from a slightly different angle, it's simply 1+2+3+4+5+6 = 21, not "one row of six" plus a random blob of fifteen.
Some silicone over it would help to insulate against shock.
glue gun :D
You could place a spot of hot glue over the mains so they're not completely exposed...
+Mike Hawk All the solder points on the LEDs though..
Holy crap! I'm watching this at 3:41 AM while doing a teardown of a digital timer. Night owls of a feather...
Grow light my ass. Even at the claimed 15W power this ain't gonna' grow anything. If it's really only giving out 5W I'd need at least 50 of them as a bare minimum.
There's a good reason LED grow lamps are so expensive.
I have opened a few of grow lamps and I believe that the power supplies used are intended for use in LED tube lights where mains isolation isn't necessary. That is why they are long and narrow in design and due to the huge volumes they are very low cost.
He's the Sean Connery of LED lighting.
I used to do things like this as a young child, the only problem was I didn't have the skill, the knowledge and/or the correct tools! The outcome was usually quite interesting.

So is 50v DC as harmful as 240v AC? I like your channel, subscribed. You have quite a calming accent.
dmak2 The 50V DC is referenced to the mains, so if you touched a solder connection on the front of the lamp while referenced to ground you would get a full mains shock.
What do you mean by "referenced" to the mains? I apologize, my knowledge of electronics is somewhat lacking.
dmak2 The easiest way to describe it is as the scenario of a 9V battery being connected to a live wire. You'll still measure 9V across the battery itself, but if you touched either of the terminals you'd get a mains shock.
Is it that there is no resistance to what the mains is supplying? I assume that the RCD in the consumer unit would trip? Either that or you'd have to rely on the fuse in the plug. So is it DC with mains "power"?
dmak2 Whether the RCD tripped would depend on which part you touched, as although you may get a mains shock it may limit the current enough to cause a severe shock without passing enough current to trip the RCD. That could be very unpleasant.
Watt a waste of good LEDs, they will never glow to their potential.
36 and 90, what a fun king coincidence.

Red is for bloom, whiter light is for vegetative growth. The harvest moon thing.
The star is not random nor is it decorative.
A female friend of mine asked me to get her a "plants lamp" for a birthday present and I just searched for that, acquiring a 50ish EUR lamp from a domestic supplier. It came overnight packed just in a plain cardboard box and inside that it was wrapped in a plain clear plastic bag, so there was no much unboxing, and I couldn't help trying it out. I found the hard pink light quite appealing for some reason. So I thought that is what she might have wanted and wrapped it up nice. We had had some incandescent based plant lamps in the 80's when they were "special" and I originally thought this might have an intense white light just as well.
I dropped it off at her party with some small gizmo I planned for the surprise effect and thought to become useful, including a touch screen glove, USB Micro/C adapter and tablet pen.
Two days later she called me and asked what the deal about it was. I asked if there was something wrong and she said "no... not really but it's just different than I expected". Turns out we both had had the same expectation. So I explained to her that as far as I know this design is made to take into account the low absorption of green wavelengths in chlorophyll and that the red and blue band together make the light appear magenta or hard pink, and if it had a closely matched green light source in it, it would appear like "TV white", which I oruginally expected as well. And while not being designed to make colorful plants look pretty, it must be a growth improving lamp.
A week later she called to ask where I had acquired it and how much it cost because two friends of hers had asked her where they could get similar fancy hard pink lamps.
Well, that's one way to deter slugs I suppose
No worries as plants probably won't grow tall enough to reach a 5Watt grow light.
I work in PCB manufacturing and I really enjoy your videos, been watching them every night for the past 2 weeks lol
absolutely shocking! these are grow lamps and are always in contact with over spray from watering
There are a great many different types of these low power grow lights now ...They ARE worth considering because they use small chips , these are much more efficient than 3W chips commonly used in big unit's , will cut your power bill by a quarter for the same light output but you will need about 80 of these lamps per square meter of grow space
A pleasant way to go I suppose! Having your entire crop burn around you whilst you sleep very, very happily! Quite amusing to think of the firemen getting the munchies halfway through the job and rescuing the fridge 😉
So Clive, you don't recommend it's use in my log cabin in the coniferous forest?
very fascinating if you was growing foods and you went to go get your plants for harvest and you got the good old voltage hit hehe would wake you up in the morning
with a grow light I would think there would be more 56K and less 10k
I thought it was a shower head with lights
Very educational and entertaining video. I'm going to be growing some vegetables in my base over the Winter. Do you happen to know how area that bulb covers and how close it has to be to the plants to be effective ?
Thanks !
I would like to see you push these lamps on a bench with a power supply. you could see how far you could push them, until they popped.
After all these videos about cheap chinese lamps I wonder if that watt meter is even exact ;-)
pcfreak1992 It's one of the most accurate I've come across, even with odd loads. If you watch the full video and follow the maths when I measure the current and voltage of the LED array it comes very close to the measured reading.
+bigclivedotcom shite,I just look at the color of the arc
link to your watt meter ?
Given the obvious component bill of materials for the circuit I find it absurd that it doesn't generate isolated DC.
I love so much your videos!
All them dongles you’d think Apple made it.
So your only quip is fixable by a dab of hot glue or if they had put contacts on the back with epoxy on the front...
the light is running a standard Edison plug but I am not familiar with the plug that you are using an adapter to connect with
+Skye Renard Standard British bayonet cap (B22).
3:20 AM? should have waited till 4:20
I guess the solution is to put a droplet of glue or silicone in the middle, so the mains connection is not touchable. After the first led the thing isn't really a danger any more.
Live plants might die when live.

m8e we need anything we can get against the triffids
jusb1066 As long they don't attact hattifnatters instead.
m8e Not sutable for rainy day.
bigclivedotcom I recommend rewiring to only 6volt and 5watt per 12LEd.
You could include instructions on how to increase the current, not for me, I know how to probably do that by, I suspect, changing a resistor value. If I were the designer of such lights I would, for 220-240 volts, connect 84 LEDs in series supplied from a SMPS constant current circuit and increase the current to at least 30mA. And of course make it safe to touch when live. Also selling them at the correct power rating :)
Thanks for putting out these videos, very interresting, keep up the good work!
Couldn't you just put a dab of non-conductive epoxy on those two spots?
+Arx Fortis To be fair, as a layman I'd expect live wires to not be exposed in such a way. Heck, high humidity and condensation could short them.
Most people would not see a problem to solve.
But all of the LED pads are going to be in circuit too
Nice methodology... for a hypothesis/guess, then test it. A good example for the noobies. Sorry to have a little moan but I find "mill-amps" grates a tad, I'm used to milli- amps.Thanks for your time.
I wanted to see him measure from a.c. neutral to one of the wires on front to see if there is a.c. leakage
these are rubbish for plant growth! i use 2 x 1000watt (340 watt actual) panels with great success! as for the colour of the leds this is to do with using the best spectrum for growth (blue) and flowering (red) :)
This 126 LED Hydroponic Death Lamp will make your plants live! What a great way to revive some dead plants.

nasty unshielded cheap LED the PCB is like an antenna. Things like this are upsetting TV reception locally near the lamps. They are quite often not specced to emissions standards.
you are one of the most likeable guys on youtube. i really like that your videos have some knowledge in them
It's amazing at what gets imported from China now, I recently bought a 240 volt in bridge rectifier. This was supposedly for testing water quality, it has 4 three inch pins which have 240 volt DC output.
Scary stuff.
Green Silver As in, a fully packaged product designed to be handled and in contact with water? All the bare bridge rectifiers I buy have 4 terminals for connecting the AC input and DC output (PCB pins and spade terminals are common on the smaller modules, whereas you'll find screw terminals on larger industrial modules). Perhaps they sent you a regular bridge rectifier that's designed to be installed in a circuit, as opposed to a finished water tester. It could even be a replacement bridge rectifier for repairing a water tester (since ebay stores rarely label things correctly).
Look up the part number on the case. If you find a datasheet for a generic bridge rectifier (and/or it has a hole for mounting), then you have accidentally bought a 4-pin part designed to be bolted to a heatsink and soldered to a circuit board. It's probably due to mislabelling or sending the wrong part.

This is the little beast, it's certainly NOT a tester in my book.
www.banggood.com/220V-Water-Electrolyzer-Heavy-Metal-Tester-Water-Filter-Instrument-p-953035.html
Green Silver Whoa, mate, that's extremely shoddy. At first I didn't think any manufacturer was dumb enough to just stuff a BR into a case with a plug, but that's exactly what they've done. Deadly stuff. 230V AC will produce about 325V DC with the appropriate smoothing capacitor on the output, excluding the 0.7 - 2V drops of the diodes. Without any capacitance you will get roughly 230V DC (100 or 120Hz pulsed DC with a peak of 325V). Hopefully they've at least included a resistor and fuse to limit the fire hazard, but it's still insane.
When I saw it I figured that something this bad I had to buy and see if it really put out the voltage I was thinking, needless to say it dose.
It's the most dangerous thing I've seen on Banggood, a potential killer.
+Grant E Yes there is a fuse, a reviewer says to take it out so your children won't kill themselves lol
A light to grow a new product dubbed "electric weed".
when you really just want a good buzz
Had something like this fall apart in my cloner due to really cheap plastic. Had a few others the LED would go out and I"d have to jump past them. They're really shitty. I've changed to using security light LED bulbs they're better guarded against moisture. You don't need that weird purple spectrum. Actually most plants hate that shit. Use the closest thing to 6500k daylight spectrum. Full spec LED grow bulbs (purps) are junk.
I would not use any lamp that was not from a brand name and CSA or UL listed. China labels many of there products "CE" which stands for "China export" and not the real "CE" that is a manufacturing standard. Manufactures from China look for any way to save a penny, but it is the rest us that are demanding cheap goods. Buying garbage products that waste your money is one thing, but when there is a shock or fire hazard from the inferior goods then its a serious problem.
Rick Rude Right legit LED lamps cost a bit but save hundreds in hospital bills and property damage.
The LED driver may be a similar design to the one I found in an LED tube (a fluoro replacement tube).
Tube: th-cam.com/video/FcPiiDuyZFs/w-d-xo.html
Driver: th-cam.com/video/52bDBKlbtms/w-d-xo.html
I think it might be a switching regulator rather than a full switching power supply.
I'd be more interested to see the light output of it vs cfl or hps
It's a shame that cheap China things are inaccurately labeled, such as wrong wattage/lumens for electronics and megapixels for cameras. Since you seem to have a lot of videos relating to electronics and routinely use the same tools, it would be nice if you would add in your TH-cam "About" section, which tools you use.
So this is one of the reasons I keep hearing about local weed grow fires?
baraxor yes. that and other stoner-rigged electronic abortions
Not to mention when they try to make hash extracts (wax, budder, shatter etc) and do it indoors and let all the runoff butane evaporate and the pilot light clicks on.
The experts I trust seem to think that a 4000k light spectrum is optimal for cannabis horticulture ie Warm white.
Green Gene and Grow mouse. Both have youTube channels that feature DIY light making.
If you want to play along at home, search youTube's channel names for "Greengenes Garden" or "growmau5".
Regretfully they are Americans and don't ship internationally... The gits. Got to roll my own. Lights that is :)
this seems to be SOP for chinese crap. I bought a 900 watt single element hot plate and it draws only 680 watts......from Sunbeam, wally world product.
your confusing the intake with the outtake.... the thibg with LEDs is they can consume 5watts and give off, i have a exspensive 1000watt LED amd it only draws about 250 which is a huge reason people prefer growing with LEDs and as far as someone letting plants hit it, well thats just a ignorant grower. plants do love light but it would take days of no1 watching before thwy got even close. i jeep mone 1.5-3ft. away always and im not all that anal about it.... just thought u should know
I bought one for my tomato plants and luckily I spotted the live connection before using it. How the hell can any company make something like this?
A single light for "tomato" plants haha
Riiiiiiiggghhht “tomato plants”
@@NoctisIgnem they had other lights as well.
Using blurple LEDs as a grow light is old tech by now. There are way better choices for growing plants indoors. Especially popular these days are white diodes with a few far red mixed in to get "full" spectrum. There are plenty of new studies that show us different light frequencies have different effects on plant growth. Also blurple LED fixtures are usually less efficient than white ones.
i know nothing about electricity but i watch ur vids anyway o-o
Oh God, the sponsored item listings below the video (mobile).
hahahahaha enjoy being on a watch list. Or something :P
I thought that's what LEDs do. I have a 45w that draws a little less power but has the light equivalent of a light higher than 45. Been growing plants with it for years now, weed, dandelions. Right now I'm growing cactus.
Good video !
Those lamps are not only a waste of money but also a waste of time and more money if you bet a crop on them. You need, at least 1W diodes, being 3 and 5 W the best. 20-25W per square foot would the optimal led lights potency to grow something.
With this lamps only the leaves on top will get anything, and still, what they get might not be enough. The plant will be very small and/or wither when trying to mature.
Careful which plants you pick - some of them can leave you seeing stars! And whatever you do, don't go for the ones that are already smoking!!!
LED lights usually only put out a fraction of what there rated to output manufacturers claim its so the product lasts longer. Takes the biscuit really almost bought a 300w mars hydro a while back until I realised it was wired or programmed or whatever to output 120w
very old gardener here; hydroponics lights are design like fishing lures: to catch gardeners no plants; plants will grow with any light if there is enough of it. remember how we used HP sodium and then metal halide? before that we used daylight fluorescents; worry only about cost and lumens, cri is important for our pleasure not the plants.
These vids are great! You should have a TV series of taking stuff apart & seeing just what's really being sold :-)
+Choppington Otter He does! It is on the TH-cam channel.

"TV" is on it's way out. To me, it's already un-watchable.
TH-cam is the future.
+James Pian Actually we too now rarely have TV on at home. But I do think his delivery and manner would come over really well on TV and there's still a lot of folks watching.
+Choppington Otter
The fame would go to his head!.LOL
We would lose the bigclive we know and love.
A 15 Watts (nominal) grow light for hydro? Are you joking? You need no less than 150 Watts for growing things.
Decent enough, A couple of coats of spray varnish or lacquer should render it safe enough. Possibly a blob of epoxy over the input wires as well?
A bit of clear coat painted over the live bits would solve the problem. That's nail polish, if anyone didn't know, it's almost as good as duct tape. :P
It's almost a confederate flag.
Dear Clive: Thanks for potentially saving a life or two. I made some very bad assumptions about the design of this lamp. Took all of them to bits and put them in the electronics waste disposal point at a store that takes e-waste.
They just run them under capacity, Wankers.... En it lol yo for everyone in the comments check out a channel called chinaunsensored your welcome
Egad, all that would have had to be done is conformable coat the LED array as a cheap way to add some protection. Perhaps conformal coating acts as a UV filter?
did anybody notice that a few leds were misplaced?
We all know what this is for! :D
Not smart buying anything that runs from mains voltage and comes from china on ebay or amazon. Looks like you can get the mandatory electric shock by touching the connections on the front. Love the comment on the plant doing the same and getting fried!
i wonder how often someone can screw on and off power socket adapters before going insane
I"m a home gardener. Has anyone used one of these? I'm curious to know if they work. They're really cheap. Most LED grow lights are ten times more expensive. And most conventional grow lights are 20 times more expensive.
Put a blob of hot glue over the center contacts. Problem solved.
Uploaded 2 days after my birthday
7 years ago. Lol
Can't you just paint over the connections with some plastidip?
thank you for the vid
Have anyone ever told you that you sound like Robin Williams.
Thought it was a shower head. Kinda want a LED Shower head now....
in china the people are smart enough not to touch the wires. and we think were the smart ones. quit wining and use them like we have some since
deanc2006 is 2006 when you were born?
no 1974 and I am an electrician, with a college degree and you?
If you were a true electrician you'd know this is a shit design. Therefore, you're a shit electrician. "Oh why do we need sockets just have the wires dangling, and when you need to use them just tape them to the appliance" is probably okay in your eyes too.
Tyler Coates "Why not, as long as you don't touch the wires it's fine, just be smart" - deanc2006 probably.
Why don't you spell "sense" correctly like you have some intelligence.
Crocodile clips. We call them Alligator clips here in Canada
why are you complaining leds are ment to draw less power meaning you got a deal
"The whole plant will become live" R.I.P. plant...
Pfffthahaha
on this episode of "this was on my recommended"
7:08 - "...then the whole plant, if it's sitting in a plastic tray, will become live." When he said that the first image that jumped into my mind was, "Feed me, Seymour!!" from _Little Shop of Horrors_. LOL th-cam.com/video/L7SkrYF8lCU/w-d-xo.html
...must be Amazon's Choice or wish.com :-)
I'm amazed at how close your guesses for the voltage and currents are to the real thing! haha
I have a smaller version of this lamp. They aren't even the correct wavelength for gardening.
POVadventure I use mine for growing plants too.... definitely legal plants....
do they work?
It's the amps that get ya not the volts
"...then the whole plant will become live." Live cannabis huh? It just might catch on... X'D
If the claim is 15W, but your powermeter showing just 5W... is it safe to assume the Powerfactor is 0.3?
It's just an exaggerated power.
