100W LED module (growlight?) with schematic.

A look at a rather odd module from eBay that looks as though it might be designed to fit into an existing housing or be used on its own. The PCB has been coated in a silicone-like gel for protection and maybe to reduce the risk of a shock, but it should be treated as being live. The reflector/heatsink is earthed/grounded.
The short lead does appear to be copper and when tested the power rating is initially 100W before the unit comes up to temperature and the circuitry throttles the power down.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
