The SureFire LM2 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 WeaponLights, such as our Shotgun Forend WeaponLights.

The result is an extremely compact head/housing unit, powered by two 123A lithium batteries, that generates 200 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 tactical runtime (runtime until output drops below 50 lumens) of 1.4 hours 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 WeaponLights: 617, 618, 620, 621, 623, 628, 629, 636, 917, 918, 920, 923, 936

Features:
* Virtually indestructible LED and TIR lens produce brilliant beam optimized for close- to medium range applications
* Construction—High-strength aerospace aluminum with Mil-Spec anodizing; coated, tempered window
* Weatherproof—O-ring and gasket sealed
