Teardown of an LED high bay factory light.04:33

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.
