With high-output white-light and infrared LEDs in one sealed unit, its recoil-proof LED generates a versatile 350-lumen tactical beam with abundant reach to temporarily overwhelm the dark-adapted vision of an aggressor and ample surround light to accommodate peripheral vision. The 120-milliwatt IR beam is invisible to the naked eye — use it on stealth operations involving night vision devices, no filter required. Switching between the two modes is achieved via a no-look, self-locking selector ring, even on the fly. Virtually indestructible white-light and infrared LEDs regulated to maximize output and runtime TIR lens shapes white or IR output into a focused beam with ample reach and surround light for close- to medium-range applications Securely attaches via its T-slot thumbscrew clamp On-the-fly bezel switching between white-light, infrared, and disable mode; no IR filter required Integral ambidextrous momentary- and constant-on switching Specifications Max Output -- White Light: 350.0 lumens Tactical Runtime: 2.5 hours Output / Runtime -- IR: 120.0 mW / 8.0 hours Length: 4.0 inches Bezel Diameter: 1.06 inches Weight w/Batteries: 4.0 ounces Batteries: 2 123A (included)
