At
less than 1/5th the price of other flashlights this bright, this is an excellent
deal.  This one uses a high efficiency CREE XLamp 3-watt LED, and uses 3 normal
AAA batteries to put out an incredible 200 lumens.  It's normally $29.99, but
it's on sale for $11.99, plus use code: BACK2SCHOOL for an additional 10%
discount, taking the price down to $10.79, and there's FREE shipping too. 
Unknown expiration date, may expire at any time. 

F-NF015 CREE XLAMP XR-C 3-WATT LED FLASHLIGHT DEAL

• Update: Mine came in!  It's incredibly
  bright for the price, size, and weight.  I'm going to keep one in each
  car.  Here's the f-nf015 (on the right) next to my $50 SureFire which uses two
  rather expensive 3v Lithium 123A batteries (left):
