Tlr-1s hp - Streamlight TLR-1S HP Strobing Rail Mounted Tactical Flashlight

It has a very bright and focused beam. I was able to get a good sight picture through an unlit reticle scope at close to 200 yards with this light. The only down side is that it must be mounted at the very end of the rail. The front lens is too big to mount behind the front of your rail system. Still definitely worth the money.
