Nightstick TWM-850XL Weapon-Mounted Light — 850 Lumens

The Nightstick TWM-850XL is a compact, high-output weapon-mounted light that delivers 850 lumens through a deep parabolic reflector to produce a usable beam out to approximately 245 meters. The housing is made from aircraft-grade 6061-T6 aluminum with a Type III hard anodized finish and features a glass-filled nylon battery door and toggle switches for durability and reduced weight. Operation is ambidextrous via dual-dependent toggle switches on each side, providing momentary-on and constant-on modes.
