Surefire LM1 Lens Conversion Assembly For Dedicated Forends - LM1-B-BK

The SureFire LM1 LED/TIR lens conversion assembly replaces the original incandescent or LED reflector-type head and battery housing of SureFire 600-series and 900-series dedicated forend Weapon Lights, such as Shotgun Forend Weapon Lights. The result is an extremely compact head/housing unit, powered by one 123A battery, that generates 500 lumens of brilliant white from a virtually indestructible LED emitter. The TIR lens produces a more concentrated, farther-reaching beam for close- to mid-range engagements. Provides a one hour runtime per battery, with gradually decreasing output afterward. Constructed of aerospace aluminum with a Mil-Spec hard-anodized finish, the LM1 is O-ring sealed for reliable operation in all weather conditions.


  • Fits: All versions of these forend Weapon Lights: 617, 618, 620, 621, 623, 328, 628, 629, 636, 917, 918, 920, 923, 936
