Keep It Simple. SureFire’s smallest and lightest weight Light couldn’t be simpler to use. Developed to fit compact, rails, it delivers 300 lumens from a single AAA battery. Our proprietary MaxVision Beam® reflector shapes the high-performance recoil-proof LED’s light into a wide, smooth sphere of light that’s ideal for closer-range identification of threats. Ambidextrous switching provides both momentary- and constant-on activation options. The XC1’s robust but compact body is constructed of lightweight, strong aerospace aluminum, Mil-Spec hard anodized and sealed to repel the elements, it’s plenty rugged enough for everyday carry, and it is so light and compact it won’t weigh you down.
