Self colour changing 3W LEDs.

I bought some of these 3W RGB colour changing LEDs from eBay to check out. Rather predictably they are not actually 3W at all, but use a typical 1W/3W “bead” package to mount the standard arrangement of chip and three LEDs found in standard 3/5/8/10mm RGB flashing LEDs.
The use of the larger base actually allows the chips to be spread wider internally and gives a fairly good mix of light. I suppose that with the better heatsinking of the chip and LEDs a slightly higher voltage could be applied to these to run them a bit harder.
