Neat Chinese LED lamps part 1.

I bought these lamps on ebay because they looked kinda neat. More in the style of high profile lamps than the common white plastic generic lamps. They claim to be rated 3W and they did actually meter out at 3W, which is surprising given the lack of thermal coupling on the aluminium core PCB to what may actually be thermally conductive plastic. the grey plastic has a hard brittle feel with a grittiness suggesting that it may be loaded with some material to aid in heat dissipation. The LEDs are running at about 50mA. In the follow up video I took apart the smallest lamp to see if it had an identical PCB, drew out the schematic and also modified one of the lamps slightly. These are pretty neat little lamps.
