Certainly not the 5W stated in the ebay listing, but also well short of the 3W driving capability of the power supply. I can only guess that's because of the use of a standard PSU module designed for driving 3 white LEDs, but actually effectively driving 2 red and 1 blue in series giving a much lower forward voltage. This is a very neat implementation of a GU10 LED lamp that uses a much more complex heatsink than traditional LED lamps. It has a threaded cover that holds a fairly thick plastic disk in place in front of a small round panel of 6 x 1/2W LEDs (four red and two blue) which is aluminium cored and glued to the heatsink using a white rubbery compound. The LEDs are wired in two parallel circuits of three LEDs in series to give a rough equivalent to three 1W LEDs in series. The base unscrews from the heatsink assembly to reveal a very standard 3W LED power supply utilising a BP9021 chip. I like the fact that the base acts as an insulated receptacle for the mains side of the module with the low voltage side being closest to the heatsink. I'm not sure how well the transformer isolates the primary from the secondary, but it does at least make an effort to shield the mains side of things.
