The powerful and versatile SureFire X300 Ultra WeaponLight for handguns and long guns features a high-performance LED that generates 1000 lumens of stunning white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. The virtually indestructible and highly efficient LED generates tactical-level light—more than enough to overwhelm an aggressor's dark-adapted vision—for 1.5 hours per set of batteries.
