The SureFire X300 Ultra now delivers a stunning 1,000 lumens of LED-generated output focused by a precision TIR lens, creating a far-reaching, high-intensity beam with a larger center spot. That's enough power to positively identify threats at significant distances while temporarily impairing an adversary's vision. This intense beam also provides extensive peripheral illumination for maintaining situational awareness. Activating the X300 Ultra is done via ambidextrous switches located at the rear of body, providing one-finger control. Press the switch on either side for momentary-on activation, flip up or down for constant-on activation. Its high-strength aerospace aluminum body is mil-spec hard-anodized for superior toughness and is O-ring and gasket-sealed to make it weatherproof.
