Streamlight ProTac Rail Mount 1 Black LED Tactical Weapon Light Features and Performance

The Streamlight ProTac Rail Mount 1 Black LED Tactical Weapon Light is a compact long gun light built for shooters who want dependable illumination, flexible battery options, and a secure mounting setup for rifles and carbines. Its fixed-mount design is intended for MIL-STD-1913 Picatinny rails, and the included M-LOK mount gives users added flexibility for modern rail systems. For defensive rifles, training carbines, and general-purpose long gun setups, this model offers a practical balance of size, durability, and usable output.

One of the most useful features of this light is its multi-fuel design. The Streamlight ProTac Rail Mount 1 Black LED Tactical Weapon Light can run on either one CR123A lithium battery or one AA battery, giving users the option of higher output with lithium power or easier battery availability with a common AA format. On a CR123A battery, it produces up to 350 lumens with a 219-meter beam distance and 12,000 candela. With an AA battery, it produces up to 150 lumens with a 141-meter beam distance and 4,950 candela. That flexibility makes it appealing for shooters who want practical performance while keeping battery choices simple.

This model also includes Streamlight’s TEN-TAP programming, allowing users to choose between high/strobe, high only, or low/high operating modes. It comes with both a push-button tail cap switch and a remote pressure switch, so users can configure the light around their rifle setup and preferred activation style. That added flexibility helps the ProTac Rail Mount 1 feel more adaptable than a basic weapon light while still keeping operation straightforward and practical for real-world use.

Built from 6000 series machined aircraft aluminum with a black anodized finish, the light is made for serious use. The compact size helps it fit naturally on long guns without adding unnecessary bulk, and the included hardware gives users multiple mounting and switching options right out of the box. For shooters looking for a durable rail-mounted long gun light with flexible battery compatibility and practical controls, the Streamlight ProTac Rail Mount 1 Black LED Tactical Weapon Light is a strong fit.
