The ground wire isn't fake, only its connection to frame is fictitious :) If the back plate was a bit stiffer and the lens applies decent pressure across the LED board, 35W of dissipation into the aluminum substrate should get it hot enough to re-melt the glue and spread it thinner over time.

For indoor use, getting a pile of these and hooking them up to be turned on/off by a DMX controller, could give a great light panel. You'd want a metal backplate and I'd probably suggest using something like a thermal 2-part epoxy for bonding them down, but I think they would be quite usable-just absolutely not with that useless wiring/enclosure.

The worst part is that the majority of people who will buy the cheapest things, are the poorest people, and there's a reasonable chance they've not had enough education or time to educate themselves regarding things like that. My daughter is an intelligent lass, currently doing a college course in mechanical and electrical engineering in fact, but I didn't bring her up until the past few years, and I was appalled to discover she had no idea how to wire a plug when she moved in with me. Didn't know how to ride a bicycle either. She does now though on both counts, but I think going forward there are going to be more and more people who don't know how to do any of these things which I've always considered to be basic life skills.

Same. I just soldered the earth wire directly to the heatsink, but I decided never to use the lamp externally. In fact, I never used it at all. The circuit board in mine was not even glued to the heatsink.

Don't worry, Clive! The thermal glue will spread out automatically as the lamp heats up ;) Although I doubt the heatsink will be enough for the wattage. Maybe it was meant to be used in case of floods, underwater, so you don't need as big of a heatsink. Also, if you stick it into ground in your garden, it's already grounded, hence, no need for the ground wire to go somewhere. Cost savings, time savings and friendly for the environment, chinese thought of it all ;)

They've cut the corners so much that it is virtually round! KW.

That lamp is indeed proper crap. I love the circuit diagram showing dodgy earth wire.

Noted that on the cheap steel backing that there are 2 divets that line up with the holes on the pcb. If you really wanted, you could slather the back of the PCB in thermal compound, drill out the 2 divets and use mounting hardware to hold the PCB down/earth it properly. Still wouldn't use it outside though.

I use a couple of these as work lights, they came with the varistor, and I chopped off all but one of the resistors and added an electrolytic. For the cost of a burger each, they were worth it.

I have the same for 3 color grow light. I have fixed the earth and used it like that. Honestly worked great for my plants but run very hot. I cut the cover and put small stepper driver heatsinks on the led driver ICs and is happily running ever since.

That would be perfect for an invention of mine which is a lamp that is a design you can acquire which is a clear glass hollow base, with the lamp works on top. The idea is to fill the inside with what are known as Yooperlites. These seemingly normal, gray rocks are rich with fluorescent sodalite and glow a vibrant orange and yellow under a UV light. So a lamp that lit them up when turned off would be a beautiful way to present either a single beautiful specimen, or my whole collection 😆 If you're not familiar: finding and displaying yooperlites is a fun hobby here in Michigan, USA

Yeah I know, time involved doing this, but, IF you had the stuff already lying around in the shed, it'd be a nice little project. Note..

And even there the line between expensive but proper professional stuff made for the road, and the cheaper pro-sumer stuff gets blurred very often. I find it VERY funny (and troublesome) that most (Western) people dunk on "China" (read: drop shippers and resellers), for their lack of safety in the stuff they sell.... While 90% of all such home-use lighting devices you can buy in the West are 100% IDENTICAL without ANY modification (except for maybe a logo) or improvements and come directly from those same Eastern manufactures. Case in point: the exact same led armature (including even the same box!) that Clive showed in this video, I find in numerous western shops with the exact same (often BS) specs and advertising (In fact, some shops show that very same armature half submitted under water!!). But with prizes ranging from $20 to $75 for the exact same 50W armature. So, _"quite expensive... must be ok then....no? Not like those cheap Chinese dangerous clones....."_ ... At least that is how most people think about it.

I have a growlight built on the same PCB and chassis, runs pretty well after I stuck a big heatsink and fan on the back.

Fitted new three core flex, all now fully earthed and included a on/off switch. They illuminate eight flourescent pads in the floor from about 2mtrs above. Now if left running they never exceed 40 degrees C at any measured point, and the temp dissipates down to 27c within 150mm from the mount. Cheap and cheerful but does the job for us.

The best way to reduce the output would be to replace the sense resistors on all three regulators with a higher value but soldering to these heatsinked boards isn't easy.

The hot glue would melt and get thinner and therefore more conductive once it gets hot enough! I suspect some bit hotter than the leds start failing, mind you, but still.

It's funny how little money they saved by not hooking the ground up. Literally a single sheet metal screw and a crimp on eyelet and it'd have been much safer. But hey, they saved $0.01 per fixture.
