Have you tried any of the LED flashlights? 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 home LED light bulbs.
(I've even seen some LED flashlights 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-LED flashlights were bright (and, indeed, compared
to a small incandescent flashlight, they are... but much more difuse). The
ones that are REALLY bright are the LuxeonŽ type LED lights. These are the
ones most likely to eventually make it into meaningful home lighting. I
have some 32 LED lamps that I use in various places. They are about the same
brightness level as the little 7 1/2 watt sign bulbs (but of course use less
than one watt). The Luxeon is many times brighter, and with just a single
light source. These are quite a bit more expensive for the higher power
ones, but the 1 watt and 3 watt versions 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.

Dear Bruce (any everyone else here),
Within the last two months General Electric and Konica Minolta have
signed a strategic alliance agreement to develop and commercialize
Organic-Light-Emitting-Diode (OLED) devices for home and industrial
lighting applications. It is their intent to have these devices on the
market within three years! OLEDs can be fabricated in sheet form which
is flexible (imagine THAT!), thin, and lightweight. This form of
lighting may eventually be incorporated into walls or ceilings,
eliminating the need for separate light fixtures (table lamps, and so
forth). Color temperature can be anything desired! They've got it NOW;
they must develop inexpensive manufacturing techniques for it to
become commercially viable.
Obviously those two companies are quite confident in their ability to
do so.
And of course the OLED's energy usage is but a small fraction of what
is used in todays bulbs.
Best,
Joe
