This review is about a newly bought 10W floodlight, i bought it on ebay and was surprised that for $5.50 total i got 3 of them, free postage, all within australia and it arrived in like 4 days via eParcel.

Anyway, ive heard these things were a bit dodgy, my assumption was that this was a 12v led with a built in inverter to run off 240vac. I was half right. It was dodgy yes, and as far as i can tell it is infact a 10W light, when i hooked it up to my inverter, dodgy as it is, it drew about 1.4A at 13.8v, with the 0.4 being the inverters idle current, which still means it drew about 13W or so.  But there is also the possibility that it was only outputting about 4-5W if the led driver is accurate, since its only a 150ma supply, again, my inverter is rather dodgy, it might have been overdrawing power.

-edit- further testing tells me that the module consumes about 10W, but the LED only accounts for about half at best, since i tested it and it only outputs 30v exactly, meaning that these are 5W lights, not 10W.

-edit- even moe testing tells me the desired voltage to run the led is 34v to get an output of 10W, 32v will only get about 5-6W out btw.

Unfortunately, the LED inside is not a friendly 12v, but instead, about 30v or so.

A big issue with this light i have found is that they do not come earthed, the earth wire is just jammed in the wire fixture nut. Its easily fixed though, there are accessible screws you can use.

Otherwise, this thing is pretty good, but to be honest, i would rather just use ~30v directly instead.

It gets awful hot though, the yellow part of the LED, i dont know if the cooling is sufficient for it yet until i run it for a while or if the inverter is underpowering it for what its rated for. There is no real regulation as far as i can tell, but maybe there is too. The big kicker for me is that its 240v and that requires more safety precautions than DC regulation.

What ill likely do is run the inverters in parallel in a nice safe box and have the wires running up the shed wall (where im installing it), carrying DC instead of AC. Plus i dont have any mains cables anyway. I dont really need this to be waterproof, which it really isnt anyway. The reason id do this, moving the inverters out of the lights is because i have 3 lights, if it were just 1, i wouldnt have a problem.

This should be within the range of allot of those cheap buck boost converters on ebay and aliexpress, if you want the source to be 5v (like a usb battery bank) or 12v from a lead acid battery.

Also, about the seals in these things, i seriously doubt that they are real, it looks more like silicone caulking compound was injected in there and this is just the shape it took, dont let these things get rained on, not without being re-sealed and/or being dc only.

Overall, considering the fact you can sometimes buy these for like $1, id say its really good for a multipurpose light, and you are totally ok to run it off DC instead, if you wire the LED up directly, but again, youll need around 30v and limit the current so your output is 10W-13W. Personally i like my work lights to be a bit more heavy duty before i run them off mains though.
