I saw this on ebay. I bid on it, won it and took it to bits.
The case is surprisingly light. That's because it's very thin and flimsy and contains mainly air.
The earthing is really quite special.

I have seen 100W and higher flood lamps [largest I've seen was 500W], but they all had multiple LED modules and the higher wattage ones had active cooling… Even the 100W one had a much larger fin array and even copper heat pipes to help transfer heat
You're WAy to skeptical. Let me ask you this. Why would the company design a heatsink that size if they thought it wasn't gonna cool the LED? Obviously they designed the heatsink for the type of LED that they used. So why wouldn't it be enough to dissipate heat? Did you design this floodlight yourself?
China made…….real 100w led need cpu heat sink with fan to dissipate heat…try to do lumens test what they mentioned …or light intensity…
So take out 1 driver and run this unit at 30w and it will last for ever ish, cheers
very polite spoken…you fae Bearsden?
They could put more heatsink fins on the back, and this light should be good!
Add a third 30w driver and see how long it will last running at 99w in total.
Late to the party but I had s batch of floodlights with this exact same casing. The PSU was different, and was a single unit. Earthing was a floating ring as previously discovered by yourself, and the wire was in US colours (black, white, green). Most of them failed in 6 months. I’m looking at fitting driverless 50w units instead.
100w = $60 US
vs
50/65W = $25 US
… yeah, that's a ripoff …
"Stuffed up the gland" is not an approved method of connection? Hmm. I'd better change my ways!
looks kinda like the 100W LED that I got (just the LED by itself though)
mine has the rounded/curved parts like this LED has
these are pretty good LED's! I got mine for 10$ and all the LED chips light up very evenly as soon as any reasonable amount of light is coming out. they're all pretty much identical in brightness)
Wow, that metal case was absolutely pathetic. You broke it with a screw driver with minimal effort.
Big Clive: Love your work!!. I have lived manufacturing lighting in China over 10years and know my products. It is alarming the garbage found on e-bay etc…! Excllent product can be manufactured in China but you have to have high standards. As a UK LIA member also I really love your work…! this is all Zhongshan garbage that hits sites such as e-bay….! Causes decent manufacturers to constantly worry over price points…..!
It's never good having an earth wire shoved up your gland…
i would not use these leds for indoor lighting, their cri is only 70 which is awful.
I have a 100w or a 70w and it has only a single ballist. Been trying to diagnose the problem with it. It will not run at all.
haha…100 watts of disappointment! lmao
i got one off ebay for 22 dollars and it's not bright at all
