Get A Grip. The mid-section and rubber grip ring of the G2ZX CombatLight are specifically designed for use with the Rogers SureFire technique. Use it in the wet, in the cold, or while wearing gloves. With a high-performance LED that produces 600 lumens of brilliant white through a micro-textured polycarbonate reflector, it provides optimal light distribution — excellent reach combined with significant surround light. And its aluminum bezel transfers heat from the LED for supreme reliability. Ergonomic tactical switching offers efficient momentary-on or constant-on activation.
