The Surefire G2 Nitrolon Xenon Flashlight is a compact, palm-sized, high-intensity incandescent flash light for tactical, self-defense, and general use, with a tough polymer body made of lightweight, abrasion-resistant, corrosion-proof Nitrolon. The Surefire Nitrolon G2 Flashlight puts out a smooth, brilliant, pre-focused tactical-level beam with four times the light of big two D-cell flashlights. This flashlight from SureFire is also great for car storage, duty carry, emergency kits, or salt-water working environments. This SureFire flashlight is bright enough to temporarily blind and disorient a person by impairing his night-adapted vision. Small size, light weight, and high output make the Surefire G 2 Flashlight a perfect everyday-carry light.
