WOW- I had no idea flashlights had reached the level that they are now available in until I recently bought a Surefire G2 LED-great light !! Bought a Fenix E20 for my EDC at work because it was an exact fit in place of a mini-mag in my holster with multi-tool.Another great light !! I'm an old new guy at the flashlight thing so it looks like another vice to go along with AR'S,knives,and ammo. Thanks for all the info folks.
