The Streamlight ProTac Rail Mount HL-X Pro Light is a high-output tactical flashlight built for AR-platform rifles and other Picatinny-equipped firearms. With 1,000 lumens on high and a 50,000 candela throw that reaches 447 meters, this gun-mounted light delivers serious illumination for home defense, tactical training, and low-light hunting scenarios. The compact, rail-mounted design keeps your rifle balanced and ready without adding unnecessary bulk or weight.
Flexibility is built in. The jack-cap tail switch supports both push-button operation and remote pressure switch input, so you can run it solo or wire a remote switch for hands-free activation. TEN-TAP programming lets you choose your operating mode: high with strobe, high only, or low-and-high for versatile light management. A low setting drops output to 60 lumens and stretches runtime to 21 hours—ideal when you need to preserve battery life or avoid overpowering close-quarters environments.
The light runs on either a Streamlight SL-B26 protected Li-Ion USB rechargeable battery pack or two CR123A lithium batteries, giving you options based on your charging setup. Built from anodized aluminum with tempered glass optics and IP67 waterproof sealing (down to 1 meter for 30 minutes), it's engineered to handle field conditions without flinching. Whether you grab the light-only head or the complete system with remote pressure switch, clips, and mounting hardware, you're getting a proven workhorse for serious shooters.

The ProTac HL-X Pro clamps to any MIL-STD-1913 (Picatinny) rail, including standard AR-platform handguards, shotgun fore-ends, and most tactical rifle setups.
Yes. The light is compatible with a remote pressure switch, which connects through the jack-cap tail switch for hands-free operation. Note that adding a remote switch changes the water rating from IP67 to IP54.
The system includes the remote pressure switch, jack-cap tail switch, remote retaining clips, double-sided tape, zip ties, and M-LOK mount hardware. The light-only version is just the head itself; you'll need a separate mount or adapter to attach it to your rail.
On low output (60 lumens), you'll get 21 hours from two CR123A batteries or 24 hours from the Streamlight SL-B26 rechargeable pack.
