Sure Fire's Scout Light Pro series rewrote the rules of Weapon Light versatility. The M340DFT-PRO Turbo Mini Scout Light Pro combines high-candela performance and dual-fuel capability. The M340DFT-PRO delivers the farthest-reaching beam of any SureFire long gun weapon mounted light in a compact form factor. As a result, it is ideal for long-range target identification. The M340DFT-PRO projects a peak beam intensity of 95,000 candela, using the included rechargeable lithium-ion battery, or 55,000 candela with a single 123A primary battery. Its precision reflector creates a tightly focused, concentrated shaft of light with minimal bounce when peering over, under or around barricades. At the same time, it provides ample spill light to help the user maintain situational awareness. Our Low-Profile Mount (LPM) delivers unprecedented versatility, allowing the user to optimize the light's position relative to the rail and other attached firearm accessories. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or compatible with M-LOK rail. Constructed of lightweight aerospace aluminum, Mil-Spec hard anodized, and O-ring sealed to keep out the elements, the M340DFT-PRO is the best-performing, most feature-rich Weapon Light for its size. Note: rechargeable battery required for 650-lumen output, 95,000 candela, 45-minute runtime, and 616-meter beam distance
