Popular with law enforcement and military operators worldwide, SureFire's best-selling Weapon Light now produces an impressive 1,000 lumens of LED output. Focused by a precision TIR lens, it generates a long-reaching high-intensity beam with a larger center spot and surrounding spill light, ideal for close- to medium-range engagements. You can rely on the X300U-B to help you clearly identify threats at significant distances while temporarily impairing your adversary's vision. It also offers extensive peripheral illumination to maintain situational awareness. Ambidextrous switching allows one-finger control for momentary-on or constant-on activation. Its rugged aerospace-grade aluminum body is Mil-Spec hard anodized for scratch and corrosion resistance and sealed to be weatherproof. It's also IPX7 waterproof to 1 meter for 30 minutes.
