The Barska 140-Lumen 3W LED Zoom Flashlight is a powerful tactical 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 140-lumen beam and a zoom function for more efficient light at greater distances. This flashlight is activated by a pressure-sensitive push on/off button, with two levels of light output and a strobing mode. Runtime for one set of 3x AAA batteries is 6 hours. Batteries are not included.
