The powerful and versatile Steiner Optics Mk4 Battle Light LED Weaponlight features a push button tailcap switch for hand-held use, and a separate integrated port for a remote cable switch when mounted on a firearm. This system eliminates the common need to remove and store the tailcap switch as required with many conventional weaponlights. It comes with a low-profile Picatinny/Weaver rail mount that keeps the light close to the rail to limit possible snags and increase user maneuverability. The Mk4 has a single 500-lumen output with a Total Internal Reflection (TIR) lens that is factory-focused to produce a smooth 10° beam without holes or hot spots that has been optimized for maximum throw.
To cut weight and reduce user fatigue the light is made of a lightweight aluminum alloy and weighs in at just 4.9 oz. Designed for durability, the housing features a corrosion and scratch-resistant anodized finish, is O-ring sealed to make it waterproof and submersible to 16', and its broad operating temperature enables it to be used with confidence in most weather and conditions.
