Small bright white LED?

Are you asking about the discrete LED or a complete flashlight?
If a discrete LED, I believe there is a 3mm Nichia white LED that burns at 5600mcd 20deg. For a complete flashlight, I think it is hard to beat the Photon for size and illumination.
The Luxeon Star LED that Peter Gransee going to use in the soon to be released Arc-LS is reported to blow the Nichia LEDs right out of the water. But those are quite a bit bigger than the 5mm Nichia LEDs and require some heatsinking.

Nichia make some really teeny tiny Surface mount LEDs...like this one....

They use the same die as the 5mm whites but emit the light in a broad wide beam. With some care you could design or adapt a lens or reflector to focus the beam, otherwise it`s an area light.
I got mine from Craig Johnson- see his "for sale" page here... http://ledmuseum.home.att.net/saurus.htm
Be warned- they are very small and soldering is exceptionally tricky without specialised equipment. I cheated and used silver conductive paint to interconnect 3 of them backlighting my Fluke bench meter`s LCD display- it was tricky too but seemed to work in the end.
If you want small, those are about as small as they get, but they are not easy to work with.

Hmm, interesting.
(And backlighting a Fluke - nice idea !)
Where do you get the silver conductive paint from Chris - is it good stuff ?
I'm looking for something like that, 'cos my soldering is awful.
Will the paint withstand some wear and tear, if used on the inside of a battery compartment instead of a wire f'rinstance.

Ps - I like the new "from" line.
