Product Description
The SureFire M640DF Scout Light Pro Dual Fuel is a rugged, rail-mounted white LED weapon light engineered for reliable performance in demanding conditions. Its Low-Profile Mount (LPM) lets you optimize positioning on MIL-STD-1913 Picatinny or M-LOK rails, reducing bulk and improving ergonomics. The recoil-proof LED and Total Internal Reflection (TIR) lens deliver up to 1,500 lumens using an SF18650B rechargeable battery or 1,200 lumens with two 123A primaries, creating a versatile hybrid beam with reach and ample peripheral spill. Built from aerospace aluminum with a Mil-Spec hard-anodized finish and sealed against the elements, this tan Scout Light Pro is purpose-built for close- to longer-range applications.
