Bright Idea: A Flashlight That Runs On Any Battery

The Panasonic Any-Battery LED Flashlight solves an age-old problem: you need the flashlight but the batteries are dead. Hunt for batteries, wrong size. Then, you hunt for the candles. But with this thing, pretty much any standard alkaline or rechargeable batteries will work: Size D, C, AA or AAA. It delivers up to 86 hours of run-time and also functions as a lantern.
