Compact and extremely powerful, the M622C ultra Scout light uses a high-performance, virtually failure-proof LED to produce 600 lumens of blinding output, and it continues producing tactical light for 1.5 hours on a set of batteries. Its output is focused by a total internal reflection (TIR) lens into an intense, far-reaching beam that also provides significant peripheral illumination, making it ideal for close- to longer-range applications. This new scoutlight configuration features the American defense manufacturing ad-sf quick-release mount. The DS07 is a waterproof switch Assembly for SureFire Scout light weapon lights. It includes a system-disable feature, a click on/off pushbutton switch, and an St07 switch Assembly with a 7 inch plug-in momentary-on remote tape switch. The integrated pushbutton and remote switch assemblies operate independently, providing switch redundancy. Constructed of High-strength aerospace aluminum with mil-spec type III hard Anodizing for superior toughness and corrosion resistance, the M622C ultra is o-ring sealed to keep out the elements. And, like all SureFire weapon lights, it's built to withstand the rigors of combat..
