The EagleTac P20A2 is the light for the people that want very high output with batteries that are easily replaceable.
The P20A2 is functionally the same as the popular P20C2, except for the fact that it utilizes 2 AA cells instead of CR123 lithium batteries. The AA cell is much cheaper and easier to find than the CR123, making it painless to replace when the time comes. The P20A2 uses the CREE XM-L LED which pushes out a max of 524 lumens on high. Output that high is hard to come by in a torch this small, not to mention at a price well under 100 dollars. This is definitely one of the most EDC friendly high output lights out there, all the while being easy on the pocket book. This one is very popular, so get it while you can!
