The Streamlight ProTac Rail Mount VIR Pro is a dual-spectrum rifle weapon light combining high-output white light with an integrated infrared illuminator for night-vision use. A head-mounted selector switches between visible and IR modes, with a safety cut-off that prevents accidental white-light activation in IR mode.
It produces 1100 lumens and 40,000 candela of white light (400m) plus a 2,300mW IR output on high. This 88138 configuration runs on two CR123A cells (SL-B26 compatible) and includes a Jack-Cap tailcap with push-button and remote pressure-switch operation. 6000-series aircraft aluminium, BOROFLOAT lens, IPX7.
