Streamlight Protac Rail Mount 1L-X PRO Long Gun Light

The Streamlight ProTac® Rail Mount 1L-X Pro is a compact Multi-Fuel weapon-mounted tactical light designed for short-barreled rifles, carbines and submachine guns. It provides strong illumination in a compact rail-mounted format, making it suitable for professional duty setups, tactical training, range use and low-light equipment configurations.

The ProTac® Rail Mount 1L-X Pro uses Streamlight’s Multi-Fuel system and can be powered by either one Streamlight SL-B9® rechargeable lithium-ion battery pack or one CR123A lithium battery. With the SL-B9® battery, the light delivers up to 850 lumens, 30,000 candela and a beam distance of 346 meters. With a CR123A battery, it delivers up to 500 lumens, 18,000 candela and a beam distance of 268 meters.

The Jack-Cap® tail cap provides dual activation options. The light can be operated directly with the push-button tail switch or through the included remote pressure switch. This gives the user flexibility to configure the light according to the weapon setup, grip style and preferred control method.

TEN-TAP® Programming allows the user to choose between three operating programs: High/Strobe, High Only or Low/High. This makes the light adaptable for different use cases, from maximum output to longer runtime and simplified operation.

The ProTac® Rail Mount 1L-X Pro mounts directly to MIL-STD-1913 Picatinny rails and also includes an M-LOK® mount for compatible rail systems. The one-handed snap-on and tighten interface allows secure attachment and removal while keeping hands away from the muzzle.

The body is made from 6000 Series machined aircraft aluminum with a black anodized finish. The high-temperature BOROFLOAT® glass is shock-mounted, anti-reflective coated and impact resistant. With the standard push-button switch installed, the light is IP67 rated and waterproof to 1 meter for 30 minutes. With the remote pressure switch installed, it is IP54 rated for water-resistant operation.
