Streamlight ProTac Rail Mount 1L-X 500-Lumen Light

The Streamlight ProTac Rail Mount 1L-X is a compact multi-fuel weapon light rated at 500 lumens and 18,000 candela. It fits a 1913 Picatinny rail and includes an M-LOK mount for compatible handguards. This non-Pro version uses a tailcap switch rather than the newer jack-cap and momentary-switch package found on model 89024.

A CR123A lithium battery is included, giving the light an immediately usable primary-cell setup. The 18,000-candela rating helps describe how the beam is driven and makes comparison with the 850-lumen USB version more meaningful. Mounting hardware is supplied with the light, reducing the number of separate pieces needed for installation.

Model 89026 is the simpler 1L-X package for buyers who want 500 lumens, multi-fuel capability, and conventional tailcap control. The 89027 USB version raises output to 850 lumens and includes an SL-B9 rechargeable pack. See more weapon lights for other compact ProTac rail models.
