The SureFire G2X Pro is a premium tactical flashlight built around the needs of emergency first responders. A press of the tactical tail-cap will instantly produce a vibrant 600 lumen beam of illumination from a durable LED emitter. Alternatively, its low output setting produces a gentle beam of 15 lumens, perfect for preserving dark-adapted vision and greatly increasing battery life. Its durable polymer body makes in a great choice for use in the cold, and its precision reflector creates a smooth, optimized beam that can reach all the way out to 187 meters.
