Meet The Dark Head-on. The Dual Fuel Scout Light Pro 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 lights position relative to the rail. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rail. The Dual Fuels 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 creates a hybrid beam pattern with plenty of reach and ample surround light. Its 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 Dual Fuel Scout Light Pro is a new twist on a legendary Weapon Light system.
