Product DescriptionThe Nightstick TCM-5B is a subcompact weapon-mounted light engineered for handguns with narrow or short accessory rails. Delivering 650 lumens from a single CR123 lithium battery, its total internal reflection (TIR) lens throws a sharp, focused hotspot reaching up to 136 meters with a clean outer halo for situational awareness. Fully ambidextrous rear-facing toggle switches provide intuitive momentary or constant-on activation, plus user-programmable strobe and battery-safe modes. Built from aircraftgrade 6061T6 aluminum with a polymer rear housing and a hard-anodized finish, this light is IP67 dustproof/waterproof and impact resistant. Designed specifically for narrow-rail subcompacts, the TCM5B fits a wide range of popular models including Glock 43X/48 MOS and Rail versions, Sig Sauer P365 XMacro, H&K HK45 Compact, Springfield Hellcat, S&W M&P subcompacts, and many more.Marketing Points 650-lumen white LED with engineered TIR lens for a tight hotspot and 136 m beam distance Ambidextrous rear toggle switches for momentary or constant-on; user-programmable strobe and battery-safe modes Rugged 6061T6 aluminum body with hard-anodized finish; IP67 waterproof and 2 m drop rated Purpose-built rail clamp for narrow/short-rail subcompact pistols; includes mounting hardware Lightweight 2.25 oz design; serialized for personal identification and backed by a Limited Lifetime Warranty Specs Light Output: 650 lumens Beam Distance: 136 meters Candela: 4,612 Runtime (High): 2.0 hours Switch Function: Momentary or constant-on; programmable strobe; battery-safe mode Light Source: LED Power Source: (1) CR123 lithium battery (included) Material: Aircraft-grade 6061T6 aluminum with polymer rear housing; Type III hard anodized Water/Dust Rating: IP67 Drop Rating: 2 meters Dimensions (L x W x D): 2.5 in x 1.1 in x 1.2 in Weight: 2.25 oz (63 g) Package Contents: Light, 2 spare Allen screws, 1.5 mm Allen wrench, (1) CR123 battery Patent: US 9,713,217 Serialized: Yes Color/Finish: Black UPC: 017398808514 MPN: TCM-5B Brand: Nightstick Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
