Streamlight ProTac Rail Mount 1L-X USB Features The Streamlight ProTac Rail Mount 1L-X USB runs on a multi-fuel power system accepting either a Streamlight SL-B9 protected lithium-ion rechargeable battery pack or a single CR123A lithium battery for flexible field charging options. On high the light produces 850 lumens and 30 000 candela with a beam distance of 346 meters using the SL-B9 pack dropping to 500 lumens and 268 meters on a CR123A. TEN-TAP programming lets the user select from three operating modes high/strobe as the factory default high only or low/high tailoring the light s behavior to the task at hand. The standard push-button tail cap keeps activation simple and intuitive without requiring a separate pressure switch. Machined from 6000 series aircraft aluminum and finished in a black anodized coating the housing is built to survive extensive live-fire testing and rugged field handling. The lens uses high-temperature shock-mounted anti-reflective coated Boroflex glass that resists damage from recoil and impact. A one-handed snap-on mounting interface keeps the shooter s hands away from the muzzle when attaching or detaching the light while the included M-LOK and Picatinny mounting hardware covers both popular rail standards. Rated IP67 waterproof with the push-button switch installed this light stands up to submersion and heavy weather making it a dependable choice for law enforcement military and serious tactical users.
