The G2Z Combatlight with MaxVision High-Output LED Flashlight from Surefire is a single-output, 650-lumen, LED light designed for tactical professionals. The CombatGrip configuration has a reduced mid-section diameter and a rubber grip ring that facilitates comfortable use of the flashlight/handgun technique. This innovative body shape is also useful for maintaining a secure grip in cold or wet conditions, even when wearing gloves. A shroudless tactical tailcap enables both momentary and constant-on modes. The Nitrolon composite housing is impact, corrosion and temperature resistant, and O-ring and gasket sealed for weatherproof performance. The specially developed reflector throws SureFire's wide, smooth MaxVision beam, optimized for your field of vision. Optimal light transmission is assured by the durable, impact-resistant coated polycarbonate window.
