The SureFire XC1-B is a small and light flashlight that can be securely attached to handguns with rails. It uses a single AAA battery to produce 300 lumens of white light. The MaxVision Beam® reflector creates a wide and smooth beam pattern, which is great for identifying objects at close range. The XC1-B has easy-to-use ambidextrous switches for both momentary and constant activation. The body is made of durable aerospace aluminum and is sealed to protect against the elements. It's rugged enough for everyday carry and won't add too much weight. Surefire has improved its XC1-B weaponlight to provide more output and enhanced switching ergonomics. It is designed specifically for compact railed handguns to provide tactical white light. The high-performance, recoil-proof LED light is shaped by a multi-faceted reflector into a wide and smooth maxvision beam, which is great for identifying threats and situational awareness at closer ranges. The compact body is weatherproof and made of aerospace aluminum with a mil-spec hard anodized finish, while the ambidextrous switching allows for both momentary and constant activation
