We’ve spent a lot of time with the Surefire M600DF Scout light – it’s one of the weapon lights we trust the most. They’re built like tanks, put out good lumens, and can easily be setup on a wide variety of weapon platforms. The Dual Fuel (DF) series provides more white light lumens than either the V or U series, and also allows the user to switch between two CR123 batteries and the larger 18650. (Using the 18650 produces 1,500 lumens; CR123s only produce 1,200.)

M600DF attached to a section of picatinny rail.

The M600DF Scout includes a rear click tail cap (momentary and constant on function), 1 18650 rechargeable battery with battery charger, and an integrated rail clamp mount.

High-performance, recoil-proof LED generates up to 1500 lumens of blinding white light and continues producing tactical-level light for 1.5 hours

Total Internal Reflection (TIR) lens creates intense, versatile beam with enough reach for longer-range applications and significant surround light for peripheral vision

Construction: Mil-Spec hard-anodized aerospace aluminum, optically coated tempered window, O-ring and gasket seals
