Introducing the SureFire M640DF-BK Pro Dual Fuel Scout Light. This advanced weapon light delivers up to 1,500 lumens of blinding white light using the included SF18650B rechargeable battery, or 1,200 lumens with two CR123A batteries. Its Total Internal Reflection (TIR) lens creates a hybrid beam pattern with plenty of reach and ample surround light, ideal for close- to longer-range applications. The Low-Profile Mount (LPM) allows for versatile positioning on MIL-STD-1913 or M-LOK rails, ensuring optimal placement alongside other rail-mounted accessories. Constructed from lightweight aerospace aluminum with a Mil-Spec hard-anodized finish and O-ring seals, this light is built to withstand the elements and the rigors of combat. The Z68 tailcap provides reliable activation with momentary and constant-on modes, protected by a shroud to prevent accidental engagement. Whether in urban environments or the field, the M640DF-TN Pro offers unmatched performance and durability for tactical operations.
