The SureFire X300 features a high-efficiency LED that generates 170 lumens of brilliant white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with good reach and significant surround light for peripheral vision. The LED has no filament to burn out or break and generates tactical-level light—enough to overwhelm an aggressor's night-adapted vision—for 2.4 hours per set of batteries. The high-strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and corrosion resistance, and is O-ring and gasket sealed to make it submersible to 22 meters. The X300 Rail-Lock® system comes with adapter plates permitting rapid attachment to and removal from either Universal or Picatinny rails. An ambidextrous push/toggle switch provides one-finger operation for either momentary or constant-on operation. Optional pistol grip switches
