Compact (pocket sized), high-intensity LED flashlight for tactical, outdoor, and general use. Puts out a smooth, brilliant beam with four times the light of a larger two-D-cell flashlight?bright enough to temporarily blind and disorient a person by impairing his night-adapted vision. And it continues producing useful light levels for an impressive 11 hours on a single set of batteries. Lightweight, strong, aerospace-grade aluminum body resists crushing or bending. Small size, high output, and extended runtime make it perfect for self-defense, camping and backpacking, emergency/disaster-preparedness kits, or everyday carry.
