Teardown (literally) of a 3W LED garden spotlight.04:33

It’s very clear that this light is actually based on a housing for a GU10 style holder and lamp. But to keep costs low they have basically fitted a round aluminium core PCB for the LEDs and the usual generic 3W driver in a bit if heatshrink.
The amount of waterproofing added to this light was annoying. It made it quite messy to take to bits and rules out any easy maintenance or repair.
The housing is not earthed, and has the loose earth wire and crimp lying loose inside. The LEDs are typical one watt bare luxeon style emitters soldered to the PCB and then reflectors with white housings have been glued over them.
I think I’d choose a version that takes a GU10 lamp and fit a standard 3W LED lamp into it. The slight downside to that being the possibility that the lamp may make poorer thermal connection with the outer housing than the PCB variant does.
