The UTG 400 Lumen Polymer Light Grip is an impact-resistant polymer weapon light and grip combo designed for secure, low-profile installation on standard Picatinny rails using a squared recoil stop. This versatile tactical accessory features fully ambidextrous controls, providing a momentary or constant-on 400-lumen main power mode alongside a momentary-only strobe setting. For adaptable illumination, the constant-on mode is scalable from 400 down to 20 lumens via a front-facing lumen control pad. Engineered to withstand harsh environments, the unit is IPX7 waterproof rated—capable of surviving immersion in up to 1 meter of water for 30 minutes—and delivers a reliable 3-hour runtime powered by two CR123A batteries.
