The TCM-5B Subcompact Weapon-Mounted Light for Short Rail handguns produces 650 lumens from a single CR123 battery. Its unique rail clamp is designed specifically for narrow-rail / short-rail subcompact pistols. An engineered TIR lens projects a tight bright spot for threat identification and confirmation that reaches 136 meters. The lens also produces a crisply defined outer halo for additional situational feedback. The TCM-5B features completely ambidextrous and intuitive rear-facing toggle switches on each side of the light to operate the momentary-on and constant-on lighting modes. A user-programmable strobe mode and battery-safe mode are available when needed. Constructed from aircraft-grade 6061-T6 aluminum with a polymer rear housing, the light comes with one CR123 Lithium battery.
