Below is a message I sent to the list a while back.  I now see this same
item at Kerr Drug for $6.99 now.  Just FYI.

Always looking for a good hack, I noticed recently an LED flashlight on
sale for $10 at the Eckerd Drugstore.  This has 21 bright white LEDs in it
and uses 3 aaa batteries in series.  All the bulbs are in parallel, so each
one is getting straight 4.5V DC.  It makes a nice little flashlight, and
I'll probably use it as one before hacking it up for the bulbs.  This works
out to $.21/LED, which is a great price, especially if you consider most
electronics places you would have to order them from, and pay shipping,
meet a minimum order, etc.  I measured .4 amps draw or 1.8W.  .4 amps might
run down those 3 aaa batteries pretty fast.  I think it said 10 hours on
the package.  If you buy one, be sure to use the "try it" button and make
sure all 21 LEDs are working, one was bad on the one I bought...

Here's a link to the same item on a
website:              http://snipurl.com/kgds

Thanks, and enjoy.
