I got a few of these little spotlight lamps from an ebay seller some time ago. They were presented as being 3W but while the generic star style LED inside is 3W it is actually driven at around 1.5W.
The construction of these is very neat. The driver is in the plastic base with a machined aluminium cup on the front. The LED is simply placed into the cup with some heatsink compound and when the front is screwed on the plastic lens/reflector presses the LED down onto the heatsinking surface.
It's easy to change the LED, although it is slightly footery soldering the short wires on.
In this instance I put in an LED from DealExtreme that was supposed to be purple, but was actually a bright shade of pink. Quite a nice vivid colour that complements deep blue and purple.
In long use these lights get just slightly warm to the touch, so the LEDs and driver modules should hopefully last a good length of time.
