I just checked these out at Cabella's today. The sales man showed me one when I was looking at some Surefires and my first thought was "It's an Energizer!". Well, I decided to humor the guy and picked up the Night Strike Compact 1AA version, all I can say is WOW! This light is not at all what I expected from Energizer. Folks these guys have jumped up a class or two. If you haven't given these lights a look... you should. I'm buying one after my wallet cools off a bit
