Description of Surefire 6PL LED Flashlight 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. Features: Virtually indestructible light emitting diode has no filament to burn out or break; lasts for thousands of hours Precision reflector creates smooth beam without spots or rings Rugged aerospace-grade aluminum body, Type II anodized in glossy black Coated Pyrex® window protects LED and reflector while maximizing light transmission O-ring sealed; weatherproof Tailcap switch: press for momentary-on, twist for constant-on Patented switch lockout prevents accidental activation
