The new Surefire Scout Light® Pro Dual Fuel is the ultimate single output WeaponLight, uniting the combat-proven elements of the M600DF Scout Light® with SureFire™s new Low-Profile Mount (LPM). The LPM delivers unprecedented versatility by allowing the user to optimize the light™s position relative to the rail. Rugged and reliable, the LPM can be easily and securely attached to any MIL-STD-1913 or M-LOK rail. The Scout Light Pro Dual Fuel features a recoil proof, ultra-high-output LED that delivers 1,200 lumens of blinding white light with 123A batteries and 1,500 lumens of light with the SF18650B* rechargeable lithium-ion battery. A proprietary Total Internal Reflection (TIR) lens shapes the recoil-proof LED™s light into a beam with plenty of reaches but enough surround light to accommodate peripheral vision, making the Scout Light Pro Dual Fuel ideal for close-to longer-range applications. A slight press of the Z68 tailcap switch will activate the momentary-on, while fully depressing the tailcap until it clicks will activate constant-on. Constructed of lightweight aerospace aluminum with a Mil-Spec Hard-Anodized finish, and O-ring sealed to keep out the elements, the rugged and lightweight Scout Light Pro Dual Fuel will endure combat-like conditions without any sacrifice in weapon maneuverability.
