Description
A 1,000-lumen multi-fuel long gun light with Jack-Cap switch redundancy, M-LOK mount and momentary pressure switch, for Picatinny or M-LOK rails.
The Streamlight ProTac Rail Mount HL-X Pro is a long gun light that produces 1,000 lumens and 50,000 candela on high, reaching 447 m, with a 60-lumen low mode for close work. Its integrated rail clamp attaches to a MIL-STD-1913 (Picatinny) rail or M-LOK compatible rails.
The Jack-Cap tail cap provides operational switch redundancy with both a push-button switch and a port for a remote pressure switch. The light is multi-fuel: it runs on one Streamlight SL-B26 protected Li-Ion USB rechargeable battery pack and also accepts two CR123A lithium batteries, which are easily replaced by unplugging the remote and removing the tail cap.
This version is supplied in black with the Jack Cap, M-LOK mount, momentary switch, mounting hardware and two CR123A batteries.
