Try these addresses http://www.spectrumled.com/ and

and can recommend each. Especially interesting is the 12VDC 1156/T10
PCB LED Lamp offered by Superbright. You can remove the bayonet base
from this lamp and wire it direct (observing polarity).


I looked at that light, I was a tad disappointed that the array simply
used a bunch of dropping resistors, to current limit the LEDs rather
than a PWM controller or constant current supply.

I am in the process of "rolling my own" array with some 5000mcd
superbright whites, and a pic based PWM controller, which, theoretically
at least, will give a nice smooth brightness control from 0-100% on,
without wasting power and heat on dropping resistors.

I have retrofitted some of my reading lights with led lamps from
Superbrightleds.com.
LEDs have a pretty tight beam angle and a blue-white color temp.
I like them OK for a task light or reading light but not for general
area lighting.
You might check out the cold cathode flourescents sold for computer
case and automotive decoration. CCF have a slightly warmer color temp
and are just about as efficient as LEDs. The tubes are great for
under counter use. I have seen circular CCF tubes installed around a
muffin fan but I haven't seen one in white.
IMTRA has some nice marine fixtures that use CCF if price is no
object.
