Description
Strobing rail-mounted pistol light for handguns with GLOCK-style or MIL-STD-1913 (Picatinny) rails.
The TLR-1s is a rail-mounted white-light weapon light with a user-programmable strobe function. It produces 300 lumens and 12,000 candela, for a 219 m beam distance and 2.5 hours of run time on two CR123A lithium batteries.
It mounts directly to handguns with GLOCK-style rails and to all MIL-STD-1913 (Picatinny) rails, using the same tool-free rail grip clamp system as the rest of the TLR-1 range, with an ambidextrous rocker switch for momentary or constant-on operation.
