Barska's 210-Lumen LED Flashlight is a small, powerful flashlight that's weapon mountable. The water resistant textured body provides a comfortable, secure grip and a beveled edge offers added protection. Its high-efficiency LED generates a brilliant, penetrating 210-lumen beam. This flashlight is activated by a pressure-sensitive push on/off button, with three levels of light output, an SOS pattern and strobing modes. Runtime for one set of 2x CR123A batteries is 2.2 hours. A momentary on/off long cable switch, 1" Weaver mounting ring and a wrist strap are included. Batteries not included.
