Decent 12V warm light bought 2008-08-22 that as of 2012 I still use as an alternative to my "cool" mains or 12V desk lighting from time to time. Good light volume (~40W incandescent equivalent) in interesting 'bulkhead' design.

Update 2008-08-23: Yesterday I ordered from UltraLEDs one of these warm-white (3500K) 9W 500lm LED dome lamps and added to my RE system. It arrived today: very good service! The dome's light intensity and colour is very close to that of a similar wattage 'warm' (mains) CFL that I have in the same room, and should be a little less depressing to work by on a cold winter's evening than the cool-white... Having both the dome and the spot on at once is pleasing too. The 9W dome light cost £40 (~USD80) whereas a similar-rating CFL might cost 1/10th of that, so the technology is here but the price needs a little work for prime-time...
