Description

***Includes SF18650A Lithium-ion Rechargeable Battery and Charger Kit***

Follow A New Trajectory. The Scout Light® Pro Dual Fuel unites the combat-proven elements of the M600DF Scout Light®. SureFire’s new Low-Profile Mount (LPM) delivers unprecedented versatility, allowing the user to optimize the light’s position relative to the rail. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rail. The Scout Light Pro Dual Fuel’s recoil-proof, ultra-high-output LED delivers 1,200 lumens of blinding white light with 123A batteries or 1,500 lumens of light with the SF18650B* rechargeable lithium-ion battery, and its Total Internal Reflection (TIR) lens shapes the beam for plenty of reach and ample surround light. It’s ideal for close- to longer-range applications. Constructed of lightweight aerospace aluminum, Mil-Spec hard-anodized and O-ring sealed to keep out the elements, the Scout light Pro Dual Fuel is a new twist on a legendary WeaponLight system.

The M640DF use the same high-performance, virtually failure-proof LED as the M600U, however, the M640DF is able to use the SF18650A rechargeable lithium-ion battery to produce 1,500 lumens OR two standard 123As to produce 1,200 lumens, and continuing to produce tactical light for 1.5 hours.  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.

The M640DF features a slightly wider body than the standard M640U Scout Light®, however it still maintains the Scout Light®’s compact design, and can be attached by means of an integral thumbscrew clamp to long guns equipped with a MIL-STD-1913 Picatinny rail. The M640DF also retains the Scout Light®’s mounting pattern, making it compatible with the Surefire RM45 offset mount and other aftermarket Scout Light® mounts.

The M640DF comes with an installed click-type pushbutton tailcap switch: press for momentary on, press further to click constant-on. The switch is shrouded to minimize the chance for accidental activation.

Constructed of high-strength aerospace aluminum with Mil-Spec Type III hard anodizing for superior toughness and corrosion resistance, the M640 DF is O-ring sealed to keep out the elements. And, like all SureFire WeaponLights, it’s built to withstand the rigors of combat.

Fits: Rifles, carbines, or submachine guns with a Picatinny rail on the forend.
