Have you tried any of theLEDflashlights? I bought several from AES.
They sell a model for $9.99 that is machined from aluminum and runs on
3 AAA batteries: "HOUSE OF DEALS 9LED/3AAAFLSLT*" see this listed at:
http://search.cartserver.com/search/...&cartid=a-6994...
It's the third item down. I have to tell you this thing is BRIGHT! AND
it's made as well as any MagLight I own. These will give you something
of an idea as to what can be done with LEDs. If this can be
accomplished with flashlights, I can't wait until they achieve this
level of lighting quality with homeLEDlight bulbs.
(I've even seen someLEDflashlights in the "Dollar Tree" store. They
have only 3 LEDs and are not as bright or as well made as the AES
models, but for only a dollar ... )
I used to think the multi-LEDflashlights were bright (and, indeed, compared
to a small incandescent flashlight, they are... but much more difuse). The
ones that are REALLY bright are theLuxeonŽ typeLEDlights. These are the
ones most likely to eventually make it into meaningful home lighting. I
have some 32LEDlamps that I use in various places. They are about the same
brightness level as the little 7 1/2wattsign bulbs (but of course use less
than onewatt). TheLuxeonis many times brighter, and with just a single
light source. These are quite a bit more expensive for the higher power
ones, but the 1wattand 3wattversions are coming down in price rapidly.

I agree with Joe and Brenda about LEDs, and I cannot believe that the
powers that be have not jumped onto the bandwagon with these things.
Their potential is enormous. They are fairly cheap, last nearly
forever (maybe that's why?) and use a shred of the energy used by any
other viable light source.
Um, that's bull. CFLs are better then most (all?) current LED based
sources when it comes to luminous efficacy. True, they have other
problems and are unsuitable for small lights (torches, car lights etc)
and for some specialist stuff like traffic lights but LEDs to not yet
beat CFLs in terms or luminous efficacy. They will probably eventually
win but they're not winning yet. And actually most government (don't
know about US governments) would much rather have things that nearly
last forever. Perhaps not the manufacturers but that's a different
matter.
