The SureFire Scout Light Pro Dual Fuel provides a highly versatile illumination solution for almost any rifle platform. As the name implies, the Scout Light Pro Dual Fuel can be powered by either a single SF18650B battery, or two 123A batteries. The twin 123A batteries gives the Scout Light Pro Dual Fuel a 1200 lumen output, with the SF18650B battery, it can produce an even brighter output of 1500 lumens. Either output is more than powerful enough to fit your illumination needs and can even temporarily impair your targets vision. It's powerful beam is seamlessly focused though SureFire's own Total Internal Reflection (TIR) lens to create a bright center spot with ample peripheral light for positive target illumination and constant situational awareness. In addition, the Scout Light Pro Dual Fuel attaches to your weapon with a Low-Profile Mount (LPM), this mount can be securely attached to both MIL-STD-1913 Picatinny rails or M-LOK rails.
