Streamlight ProTac Rail Mount HL-X Weapon Light with Remote Switch, 2 CR123A Batteries, Aluminum Black

The Streamlight ProTac Rail Mount HL-X is a versatile, compact weapon light built for shooters who need serious illumination on their rifle or carbine without the bulk. This 1,000-lumen tactical light mounts directly to MIL-STD-1913 (Picatinny) rails and includes an M-LOK adapter, so you can mount it on modern rail systems too. Whether you're running a dedicated rifle light for home defense, duty work, or precision shooting, the HL-X delivers the output and flexibility to handle the job.

What sets the HL-X apart is its dual-switch design: you get a remote pressure switch for one-handed operation during shooting and a traditional push-button tail cap switch for hands-free modes or backup control. Streamlight's TEN-TAP programming lets you select from three different operating modes—high with strobe, high only, or low/high cycling—so you can optimize the light for your specific needs without fumbling in the dark. At 1,000 lumens on high, you'll push a 447-meter beam with enough intensity (50,000 candela) to identify threats or navigate tight spaces. Drop to 60 lumens and you get a full 21 hours of runtime on a pair of CR123A batteries, perfect for extended low-light operations.

The light runs on either two CR123A lithium batteries or Streamlight's SL-B26 rechargeable battery pack, giving you flexibility in the field or at home. The anodized aluminum body is built tough—impact-resistant tempered glass lens and sealed construction mean it'll survive the rigors of regular use. IP67 rating with the tail cap switch and IP54 with the remote switch handle water exposure. Everything you need ships in the box: both switches, mounting hardware, clips, and the M-LOK adapter.
