Batteries - Two SureFire lithium 123A 3.0 Volt with 10-year shelf life (included)
SureFire P60 xenon gas-filled lamp assembly with 65 lumens output for 60 minutes. Construction - Non-conductive, corrosion-proof Nitrolon polymer with impact-proof Lexan lens window. High light output (up to four times brighter than a two D-cell flashlight). No Hassle Lifetime Guarantee: If it breaks, we fix it!
The SureFire G2 flashlight is powered by two lithium batteries (10-year shelf life) and made of Nitrolon, a proprietary polymer compound that is lightweight, corrosion-proof and non-conductive. A molded-in gridlock pattern allows for a sure grip in any weather, and although three to four times brighter than a typical 2-D cell flashlight this lightweight powerhouse is less than five inches long; making it ideal when space is at a premium and weight is an issue.

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. Patented switch lockout prevents accidental activation
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 flashlightbright 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.
