SureFire's smallest and lightest weight Weapon Light has been upgraded to deliver more output and feature even more ergonomic switching. The new XC1-B was specially developed to equip compact railed handguns with a source of tactical white light. A special multi-faceted reflector shapes the high-performance, recoil-proof LED's light into our wide, smooth MaxVision Beam(TM), which is ideal for closer-range identification of threats and situational awareness because this useful beam is also optimized for human vision. The XC1-B's robust but compact body is constructed of lightweight, strong aerospace aluminum hard anodized with a durable Mil-Spec finish. Measuring less than 2.5 inches long and weighing in at under two ounces, the rechargeable AAA powered XC1-B won't weigh down a handgun, either. Ambidextrous switching provides both momentary- and constant-on activation options. Momentary-on activation is achieved by placing your support hand thumb on top of either of the two rear downward-activated switches and pushing down. The XC1-B will stay in momentary mode for as long as either toggle switch is depressed and held in the on position beyond a fraction of a second. Constant-on activation is achieved by quickly tapping either one of the momentary switches. To turn off the constant on mode, quickly touch and release either toggle switch. It can also be achieved by using your support hand to push the center crossbar switch from left to right.
