Yet another Chinese ebay lamp gets taken to bits. This one is kinda neat because it is a fairly minimalist design based on a typical mini switchmode supply and star LED in a basic aluminium heatsink and lens assembly. It's actually quite functional and doesn't get excessively hot in operation, which will ensure a good LED lifetime. The LED itself seems to have a slightly smaller profile than the typical Luxeon Star package, and is held in contact with the aluminium heatsink by the pressure of the lens being screwed against it. There is a bit of heatsink compound at the back of the LED. This lamp is quite serviceable in that the LED could be changed or upgraded if desired.
The power supply is a typical BP3102 style mains LED driver which has a minimal component count, and while it should isolate the LED from the mains via the output transformer, I wouldn't trust anything like this as being 100% isolated due to minimalist separation between mains and the low voltage side.
The lamp is rated at 2W but my plug-in power analyser suggested 1.5W which is good enough and besides I prefer my LEDs to be run cool. I really like this lamp for its logical and functional design.

    I couldn't even have told you I was anywhere near 100 videos. It's quite surprising.
