About SureFire LM1

Let the SureFire LM1 3V LED Conversion Head revolutionize your dedicated forend WeaponLights. This innovative upgrade replaces the original incandescent or LED reflector-type head and battery housing of SureFire 600-series and 900-series, such as Shotgun Forend WeaponLights, transforming them into a high-performance LED light source.

The result is a compact, durable head/housing unit, powered by a single 123A battery. It generates an impressive 500 lumens of brilliant white light from a virtually indestructible LED emitter, ensuring reliable illumination when you need it most.

The LM1's TIR lens is designed to produce a more concentrated beam, providing superior light reach for close- to mid-range engagements. This versatile conversion head offers a solid one-hour runtime per battery, with a gradual decrease in output afterward, ensuring consistent performance during extended use.

Constructed from high-quality aerospace aluminum and finished with a Mil-Spec hard-anodized coating, the LM1 is designed to withstand the rigors of use in any environment. Its O-ring seal ensures reliable operation in all weather conditions, making it an ideal choice for those seeking a durable and reliable lighting solution for their weapon.

Upgrade your lighting game with the SureFire LM1 3V LED Conversion Head, a specialized product designed for dedicated forend WeaponLights.
