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.

    I LOVE that pink, it's exactly what I need for my neon-ish project. anyone knows what to search for if I wanted for ex an LED strip or 5mm LED with that color?

    I love those pink LEDs! Radio Shack gets them in stock from time to time, and I snap them up whenever I see them. The neon stroboscope lamp on my turntable crapped out about a year ago, so I made a really cool-looking replacement using those pink LEDs.

    dude, too much thermal goop actually insulates it apparently… is it thermal adhesive or just paste?

    Can I ask, what soldering iron do you use? I have been buying cheap ones for years but I am fed up with them failing…
