I bought 4 earlier-generation versions of these a couple years ago because they seemed super bright... However, _these_ are ridiculous, don't-look-at-them-you'll-go-blind, got-a-camera-flash-straight-in-the-eyes, burn-your-retina bright...! http://www.samsclub.com/shopping/navigate.do?dest=5&item=425248 I got one of these for a present - also painfully bright, comparable to the luxeon above... http://www.511tactical.com/browse/Home/All-Products/Flashlights/D/30000/P/1:100:50000:50500 I got the larger one (UC3.400), ultrabright, cool thing is no batteries, it uses capacitors instead, charges in 90 seconds, 2 hrs run time, good for 50,000+ charge cycles. Comes with a lighter-socket-12v-dc-powered charger, although an a/c adapter is available for additional purchase; any a/c converter that provides 12v-dc lighter-socket power would work though. Has regular, high-power, & strobe modes, although you have to hold the power switch on to get max bright. LED flashlights have made a lot of progress in the brightness/whiteness areas it would seem... anyone have other suggestions for bright flashlights?
