The powerful and versatile SureFire X300 Ultra WeaponLight 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. The high-strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and is O-ring and gasket sealed to make it submersible to 22 meters. The X300 Ultra is also versatile and can be attached to a pistol or a long gun since its Rail-Lock system permits rapid attachment to and removal from either Universal or Picatinny rails. Its integral ambidextrous push/toggle switch provides one-finger operation for either momentary or constant-on operation. Optional DG grip switches are available for use with a pistol, and an XT07 tape switch permits the X300 Ultra to be activated when attached to a long gun without altering your grip on your weapon.
