Complete The Look

The Surefire Dual Fuel Scoutlight Pro Weaponlight features the Low Profile Mount which offers versatility by allowing you to optimize the light's position relative to the handguard. The Dual Fuel Scout Light has an ultra-high output LED that puts out 1,200 lumens of white light with 123A batteries or 1,500 lumens with a SF18650B battery. 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. The LED is recoil-proof and a proprietary Total Internal Reflection (TIR) lens shapes light into a beam with plenty of reach 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 tailcap switch will activate the momentary-on, while fully depressing the tailcap until it clicks will activate constant-on.

The LPM can be mount on a MIL-STD-1913 or M-LOK rail.
