Two new rail-mountable LED tactical lights from Streamlight, the TLR-1 and TLR-2, utilize a three-watt Luxeon LED to produce up to 80 lumens of blinding white beam, and a bright secondary halo of light while mounted on a firearm. The TLR-2 adds an integrated aiming laser. Both offer up to 2.5 hours of continuous runtime and an LED featuring a 20,000-hour lifetime. The TLR-1 and TLR-2 are powered by two, 3-volt CR123A Lithium cells. Both lights offer the ability to mount securely to any Glock- or Picatinny-style rail.
With low cost .22LR ammo and a 16+1 capacity, you can nail paper bad guys for pennies a pop.
