The TWM-350 Tactical Weapon-Mounted Light uses an LED rated at 350 lumens working in conjunction with a high-efficiency deep parabolic reflector to create a usable beam of light rated at 215 meters. This weapon light features a unique and completely ambidextrous toggle switch on each side of the light to operate the momentary-on and constant-on lighting modes. The housing of the TWM-350 is constructed from aircraft-grade 6061-T6 aluminum with a glass-filled nylon polymer battery door and toggle switch. Power comes from two included CR123 batteries. (Not compatible with rechargeable batteries.)
