See Farther. The M640DFT-PRO Turbo Scout Light Pro combines the best attributes of the standard M640 Scout Light Pro with high-candela performance and dual-fuel capability, and it delivers the farthest-reaching beam and longest runtime of any SureFire long-gun Light. Ideal for long-range target identification, the M640DFT-PRO projects a blinding, peak beam intensity of 100,000 candela when powered by the included SF18650B rechargeable lithium-ion battery, or 90,000 candela when powered by two 123 lithium batteries. 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 M-LOK rail. Constructed of lightweight aerospace aluminum, Mil-Spec hard anodized, and O-ring sealed to keep out the elements, the M640DFT-PRO is the best-performing, most durable, and most feature-rich Light for its size.

Great light. Fast shipping!

This SF light has a tight cone, similar to a Modlite OKW head and lots of candela. Using this on my 14.5” AR and will be buying a couple more from IJ Tactical.
