SureFire E2E Executive Elite Hard Anodized

This flashlight rocks. It could blind an elephant and is only about the size of a short cigar (robusto). The E2E is brighter than those huge maglights the cops carry. It has one soft rubber on/off click button at the back, and has a cool clip that you can snap on to a baseball cap or a pant pocket. My buddy and I were spelunkering and his headlamp started to die, so I whipped out my trusty military grade SureFire and lit the cave up like it was Christmas.

It runs off two lithium batteries. The one drawback is this thing is so powerful that it will drain the batteries in about 45 minutes. It isn't really intended for prolonged use or to take the place of a headlamp. However if you need lots of light really quick this is the flashlight for you.
