The TCM-550XL-GL Compact Tactical Weapon-Mounted Light with Green Laser uses a super-bright LED rated at 550 lumens working in conjunction with a precision-engineered total internal reflection (TIR) lens to create a bright white beam of light rated at 136 meters. This weapon light features completely ambidextrous and intuitive rear-facing toggle switches on each side of the light to operate the momentary or constant-on of the white light, Class IIIa 532nm daylight-visible green laser, or light and laser together. The housing of the TCM-550XL-GL is constructed from aircraft-grade 6061-T6 Aluminum with a polymer rear housing. Includes five handgun-specific modular rail inserts (pre-configured with C1 insert for Glock pistols), two spare Allen screws, aiming and installation Allen wrenches, and one CR123 Lithium battery.
