Streamlight ProTac Rail Mount 1L-X Weapon Light 850 Lumens – 89026

The Streamlight ProTac Rail Mount 1L-X (SKU 89026) is a compact multi-fuel rail-mounted rifle light producing 850 lumens output and 30,000 candela peak beam intensity for a 346 metre beam on an SL-B9 rechargeable pack, or 500 lumens and 18,000 candela for 268 metres on the included CR123A lithium cell. It is 4.64 inches long, built for short carbines and compact long guns.

This version uses a simple push-button tail switch with no pressure pad, has TEN-TAP programmable mode order, and mounts to MIL-STD-1913 Picatinny rails with an M-LOK mount included. The body is 6000-series black anodised aircraft aluminium with a glass lens, rated IP67 with the tail switch fitted. Note that 89026 is supplied with a CR123A cell only — no SL-B9 pack or USB cord.

How It Compares

For the same light supplied with the SL-B9 pack and cord, so it runs at the full 850 lumens out of the box, see the Streamlight ProTac Rail Mount 1L-X USB rifle weapon light; if you want remote pressure-switch capability, the Streamlight ProTac Rail Mount 1L-X USB Pro rifle weapon light adds the Jack-Cap. For a full-size body with 50,000 candela see the Streamlight ProTac Rail Mount HL-X rifle weapon light, or browse every rifle and shotgun mounted light.

Frequently Asked Questions

What rail does the Streamlight ProTac Rail Mount 1L-X fit?
The Streamlight ProTac Rail Mount 1L-X fits MIL-STD-1913 Picatinny rails directly, and an M-LOK mount is included in the box for M-LOK handguards.

What does multi-fuel mean on the Streamlight ProTac 1L-X?
Multi-fuel means the Streamlight ProTac Rail Mount 1L-X gives its full 850 lumens and 30,000 candela on an SL-B9 rechargeable pack, or 500 lumens and 18,000 candela on a single CR123A lithium cell, and only the CR123A is supplied with part number 89026.

Is the switch on the Streamlight ProTac 1L-X momentary or constant?
The Streamlight ProTac Rail Mount 1L-X uses a push-button tail switch that gives both momentary and constant-on operation, and this version does not accept a remote pressure pad.

Should I buy the Streamlight ProTac 1L-X or the 1L-X Pro?
The Streamlight ProTac Rail Mount 1L-X uses a simple tail switch only, while the 1L-X USB Pro adds the Jack-Cap tail cap with remote momentary pressure-switch capability and ships with the SL-B9 rechargeable pack.
