Virtually indestructible high-efficiency LED emitters, 600 lumens of maximum output, precision reflectors, and sleek, corrosion-resistant polymer bodies are the foundation of every SureFire G2 light. The G2X Pro is the most versatile of the series. It features a useful low output of 15 lumens for less critical tasks while extending runtime. Its 600-lumen high output can also reach far into the darkness to light up any environment. Its press/click tailcap switch provides useful momentary-on activation as well as constant-on activation. The G2X Pro is a powerful performer that’s durable enough to satisfy the essential needs of any emergency first responder.
