The new Surefire M640DF Scout Light® Pro Dual Fuel (M640DF-BK-PRO) 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 (Picatinny) or M-LOK rail, and every Scout Light Pro model includes mounting cleats for both rail styles. 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 tail-cap switch will activate the momentary-on, while fully depressing the tail-cap 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.

Note: SF18650B battery required for 1,500-lumen output, 1.5 hours runtime, and 250-meter beam distance
