Streamlight ProTac Rail Mount 1L-X USB 850-Lumen Light

The Streamlight ProTac Rail Mount 1L-X USB is the rechargeable, higher-output 1L-X rail light in this pair. It produces 850 lumens and 30,000 candela for compatible 1913 Picatinny rails, compared with 500 lumens and 18,000 candela on the CR123A package. The black anodized body stays compact while the rechargeable SL-B9 system raises the available output.

Streamlight includes a tailcap switch, mounting hardware, M-LOK mount, SL-B9 rechargeable battery pack, and USB cord. That makes this version convenient for a user who wants a rechargeable battery included rather than starting with a primary CR123A cell. The dual-fuel description also gives the light more flexibility than a rechargeable-only system.

Choose model 89027 when the additional output and USB rechargeable package are worth the step up from model 89026. The host should still be checked for compatible mounting space, especially when deciding between the 1913 and included M-LOK hardware. Compare other weapon lights for longer-range and higher-output ProTac options.
