SureFire G2 lights are built with virtually indestructible high-efficiency LED emitters, precision reflectors, and sleek, corrosion-resistant polymer bodies, providing up to 600 lumens of maximum output. The G2X Pro is the most versatile among the G2 series, featuring a low output of 15 lumens for non-critical tasks, which extends its runtime. Its high output of 600 lumens can reach far into the darkness to illuminate any environment while also providing sufficient surround light for situational awareness. Its press/click tailcap switch allows for momentary-on activation and constant-on activation. The G2X Pro is a reliable and sturdy flashlight that meets the essential needs of emergency first responders.
