this caught my eye from March/2004 issue of Popular Photography -
LEDs Instead Of Flash? Ridiculous!

Being a flashlight enthusiast (and, alas, a collector), I've been watching LEDs appear more and more often in flashlights. And the tiny, single-bulb LED flashlights on keychains that I gave as presents during the 2002 holiday season wound up becoming the only lights some of my New York City friends had as they trudged up and down countless skyscraper stairways during last year's blackout.
Even though some of these flashlight owners went up and down stairs many times, their flashlights never dimmed, and I haven't yet heard of one with burned-out batteries.
The batteries in my own, larger-LED flashlights using AA or C alkaline cells last 10 times longer than my incandescent-bulb flashlights. The beams of these flashlights are so strong that they can even hurt your eyes if you look at them directly.
