The Energizer Quick Switch flashlight's main gimmick is the sort of obvious stroke of brilliance that apparently takes 100 years to develop. It's a regular flashlight that can take AA, C, or D cells - whatever you've got handy. Obviously, your run time will vary, but the brightness of the flashlight will remain the same no matter what. Energizer has already shipped two truckloads of the flashlights to Florida, although they noted they "weren't planning on launching this in the middle of the hurricane." (Thanks, Cletus!)
