The Streamlight ProTac Rail Mount 1L-X USB Pro (SKU 89025) is the top-specification compact rail-mounted rifle light in the 1L-X line, producing 850 lumens output and 30,000 candela peak beam intensity for a 346 metre beam on the included SL-B9 USB rechargeable pack, or 500 lumens and 18,000 candela on a CR123A lithium cell.
Its Jack-Cap tail cap runs a push-button and a remote momentary pressure switch with full redundancy, so either can fail without taking the light out of action, and the momentary pressure switch, M-LOK kit, hardware kit and 2.5 mm Allen wrench are all in the box. TEN-TAP programming sets the mode order. The body is 6000-series black anodised aircraft aluminium with a BOROFLOAT lens, rated IP67 with the push-button and IP54 with the remote fitted.
How it compares
If you do not need the remote, the Streamlight ProTac Rail Mount 1L-X USB rifle weapon light is the same light with a plain tail switch, and the Streamlight ProTac Rail Mount 1L-X rifle weapon light ships with a CR123A instead of the rechargeable pack. For a full-size body at 50,000 candela see the Streamlight ProTac Rail Mount HL-X Pro USB rifle weapon light, or browse all rechargeable rifle and pistol lights.
Ideal for
- Night fox and vermin control where a pressure pad on the handguard is quicker than a tail switch
- Civilian Service Rifle, straight-pull and 3-Gun carbines with short handguards
- Builds that need switch redundancy rather than a single point of failure
- Airsoft and training rifles set up like the real thing
