Yet another random purchase of a lighting product for disassembly. This one was actually quite expensive at £65, but that's probably largely due to the size for shipping.
It's a high bay light designed for factory and warehouse use, with a standard high power LED array mounted on a heatsink with a lens assembly to direct the light downwards. It has a reflector that could have been reversed to make the shipping somewhat more compact, or even just left off. The light from the LED does not at any point actually touch the reflector, so it's function is a bit of a mystery unless they treat it as part of the heatsinking.
The core of the light is a big chunk of stylish aluminium extrusion designed to accommodate the LED, lens, reflector and top housing with channels for inserting self tapping screws.
The housing at the top contains a standard LED driver which is just loose and rattling about inside. And by rattling about, I mean it's been clattering about in there on the end of its wires since it left the factory it was made in! The screw that holds the earth wire to the light was not fully tightened in, so the wire was just loose.
The four screws that held the reflector on were also not fully tightened.
The whole light comes in a box sandwiched in suitably shaped polystyrene/styrofoam packaging with a bag of hardware including a chain and a hook plate.
These lights are available in various power ratings with the only differences being the LED, driver and the length of the heatsink extrusion. The price seems to go up disproportionately to the power rating.
Here's the link to the UK stock of the Chinese seller this one came from. http://www.ebay.co.uk/itm/331054305139

We are now up to 300 watt ! , wahooo!!
The finish on that heatsink looked pretty rough to me. And the thermal design? Lousy at best. Where is the airflow? I'll bet that the difficulty you had with that many screws was due to the thing being assembled with a power screwdriver to speed things up.
that heat sink seems like overkill for 30w lol
Interesting light, I wonder how they would work as photographic lamps? The Ebay link in the description is dead but I searched for "LED high bay factory light" and there is a good selection of designs, including some with E27 fitting that would fit my existing lighting stands. There are 100W lights for under £20 each. I think they would be worth trying, they would be a lot less fragile than the big 135W CFL that I have been using.
theres a 200w version of this with 4 50w led chips for £125
i prefer the 400w mercury vapor high bay light.
That is an amazing heatsink, would be a great show piece of an overclocked PC
so why do we not get to see the heat dissipation, you say you might just do that (switch it on and just let it sit for a while to get a chance to observe how good the heat sink is doing) and then you cut the video off after saying that, the end
i would probably cut a hole in the top and add a computer fan for cooling
Holy shit, this Lamp looks so cheap!
Its not that is bad or something, but the whole selection of materials just screams cheap!
Im looking for new lights for my garage/shop and I think some of these are the ticket. Do you think they would be usable if they were about 15ft off the floor?
Nice wallpaper
Too much caffeine m8 🙂
I've used Ali express once, 3 items on one order and they were all defective and or fake. This was before they re did their site to look like the other popular Chinese discount sites.
Did you swap out the LED for a warm white when you got one?
