In the demanding world of tactical operations, where split-second decisions and environmental adaptability can mean the difference between success and failure, the equipment an operator chooses must be as reliable as it is versatile. Streamlight, a name synonymous with durability and innovation in the illumination industry, has addressed this need with the ProTac Rail Mount 1L-X, a compact powerhouse that redefines the standard for weapon-mounted lighting. Specifically designed for the unique requirements of short-barreled rifles, carbines, and submachine guns, this tactical light offers a blend of high-output performance and user-friendly control that makes it an indispensable tool for law enforcement, military personnel, and civilian tactical shooters alike.

At the heart of the ProTac Rail Mount 1L-X is its revolutionary multi-fuel capability, a feature that ensures the operator is never left in the dark due to a dead battery. The light is primarily powered by the Streamlight SL-B9 protected Li-Ion USB rechargeable battery pack, which delivers peak performance and is both economical and environmentally friendly over the long term. However, recognizing that field conditions are not always predictable, Streamlight has engineered the 1L-X to also accept a readily available CR123A lithium battery. This dual-fuel flexibility is a tactical advantage; it allows the user to leverage the high-performance rechargeable option during training and routine operations, while the ability to instantly switch to a common lithium battery ensures the light remains functional when recharging is not an option, even in austere environments far from a power source.

The true intelligence of the ProTac Rail Mount 1L-X lies in its sophisticated TEN-TAP programming interface. This intuitive system allows the user to select from three distinct operational programs, customizing the light?s behavior to suit the specific demands of the mission. Out of the box, the light is set to a High/Strobe mode, a powerful deterrent that combines maximum illumination with a disorienting strobe effect for close-quarters scenarios. For those who prefer a more straightforward approach, the second program offers a High-Only setting, ensuring that every press delivers the full blinding force of the light. Finally, the third program provides a Low/High sequence, starting with a 100-lumen beam for administrative tasks or navigation, which can then be escalated to full power with a second press. This level of control ensures the light adapts to the operator, not the other way around.

Performance data for the ProTac Rail Mount 1L-X is nothing short of impressive, showcasing the remarkable capabilities of its respective power sources. When running on the Streamlight SL-B9 battery, the light unleashes a blinding 850 lumens, generating a concentrated 30,000 candela that produces a beam distance of 346 meters. This intense, far-reaching light is ideal for identifying threats at significant ranges, providing a critical tactical advantage. For a runtime of thirty minutes, the operator commands a wall of light capable of overwhelming an adversary?s night vision. When the user opts for the CR123A battery, the light still produces a formidable 500 lumens, with 18,000 candela and a beam distance of 268 meters, sustaining this output for one hour and forty-five minutes. In its low setting, the light provides a practical 100 lumens and 3,400 candela, reaching out to 117 meters, with a runtime of four and a half hours on the SL-B9 battery and an extended six and a half hours on the CR123A, making it perfect for map reading, room clearing, or extended patrols. The strobe function, a powerful non-lethal tool for disorientation, runs for one hour and fifteen minutes on the rechargeable battery and two and a half hours on the lithium cell.

The ProTac Rail Mount 1L-X is engineered for immediate action, featuring a standard push-button tail cap that provides a more traditional and intuitive activation method. This design choice offers a distinct and secure click for constant-on activation, along with momentary operation, giving the user precise control over light discipline without the need for a pressure pad and its associated wiring. This streamlined approach reduces potential points of failure and simplifies the mounting and operation of the light on a variety of weapon platforms. Whether for a patrol officer clearing a building, a soldier operating in a low-light environment, or a competitive shooter engaging in dynamic courses of fire, the Streamlight ProTac Rail Mount 1L-X is the quintessential compact tactical light, delivering exceptional versatility, power, and performance when it matters most.

Key Features

• Engineered specifically for short-barreled rifles, carbines, and submachine guns, this compact tactical light is a trusted choice for law enforcement, military personnel, and tactical operators who demand reliability in low-light environments.
• Activated via a standard push-button tail cap, the light offers both momentary and constant-on operation without the complexity of a pressure pad, ensuring a simpler, more dependable interface on the weapon.
• Its multi-fuel design accepts either the Streamlight SL-B9 protected Li-Ion USB rechargeable battery pack for peak performance, or a single CR123A lithium battery, guaranteeing functionality even when recharging is impossible in the field.
  
• The built-in TEN-TAP programming lets the user choose from three distinct operational modes: High/Strobe (factory default), High Only, or Low/High, allowing the light to be tailored to specific tactical scenarios.
• When powered by the SL-B9 battery, the light delivers 850 lumens with 30,000 candela and a 346-meter beam distance on High for 0.5 hours, while Low mode provides 100 lumens, 3,400 candela, and a 117-meter beam for 4.5 hours, with Strobe running for 1.25 hours.
• With a CR123A battery installed, High mode produces 500 lumens, 18,000 candela, and a 268-meter beam for 1.75 hours, while Low mode maintains 100 lumens, 3,400 candela, and 117 meters for an extended 6.5 hours, and Strobe lasts 2.5 hours.
  
• Combining high lumen output, exceptional beam reach, and flexible power options, this light provides superior visibility and tactical superiority in any critical engagement, from close-quarters clearing to extended patrols.
