Hi,
LED flashlights are expensive. I had a spare 2 D cell flashlight. I
ordered two high output LEDs ($2.99 ea.) from Jameco Co. part # 217525CD
(MCDP-3004C). I took a standard flashlight bulb and carefully removed the
glass bulb. I wicked away the solder at the bottom exposing a hole. I bent, at
right angle, the short negative leads of each LED and inserted the two LEDs in
the bulb base. I soldered the positive leads at the base bottom and negative
leads to the side. Now I have a flashlight that is bright enough for 98
percent of what I use a flashlight for, and it draws about 18 ma!!!!!!

Tip for your old computer (reduce discard pollution too):
If you can't sell your old computer, don't throw it away. Use it to backup
your software by transferring files/folders from your new computer or laptop
to it. I transferred my Windows folder and other stuff to my old computer
using "PC Link", which I downloaded from www.simtel.net (cool site).
