SureFire G2X Pro Features The SureFire G2X Pro delivers 600 lumens of high output through a precision reflector with a 187-meter beam range for far-reaching illumination with ample surrounding light for situational awareness stepping down to 15 lumens for close-range tasks where extended runtime of up to 52 hours is more practical. A press/click tail cap switch provides both momentary-on and constant-on activation in a single intuitive interface for reliable one-finger light control across emergency tactical and everyday use scenarios. Two CR123A batteries with a combined high-output runtime of 1.5 hours and low-output runtime of up to 52 hours are included for immediate out-of-the-box deployment. The dual-output EDC flashlight is built from a sleek corrosion-resistant polymer body with aluminum components in black for a lightweight durable construction that withstands the demands of emergency response and everyday carry without special maintenance. Waterproof construction ensures reliable performance in rain and adverse field conditions for a light designed to function when first responders and outdoor users depend on it most. At 4.40 oz and 5.20 overall with a 1.25 head diameter the G2X Pro maintains a carry-practical profile suited to pocket pack and duty belt carry across a wide range of applications.
