The black 500-Lumen LED Head for Scout M600/620 Weaponlight from Surefire can be used as either a replacement or an upgrade, depending on the version of Scout flashlight you have. It is a replacement for lights that came with an LED emitter, or you can upgrade any two-battery M600/620 Scout weaponlight that has an incandescent bulb. It also will convert an M620V Scout to high-output white-light only.
Utilizing the Total Internal Reflection (TIR) lens, the beam is pre-focused at the factory with a tight, smooth center cone of light and a wide peripheral ring to help you maintain your situational awareness. Built for daily-use the head is made of aluminum with a corrosion-resistant black Mil-Spec anodized finish. It is also o-ring and gasket-sealed to be water-resistant.
