SureFire M640DFT Pro Turbo Scout Light

The Surefire M640DFT Turbo Pro is a dual fuel, high candela light and part of the Scout Light Pro series, and is part of the Scout Light Series. It combines the best attributes of the M640 Scout Light Pro with high candela performance and dual fuel capability. The light delivers the farthest reaching beam of any Surefire long gun light, with the longest runtime. It is ideal for long range target identification.

The M640DFT projects a blinding, peak beam intensity of 71,000 candela using the included SF18650B rechargeable lithium ion battery, and 71,000 candela with two 123A primary batteries as well. It offers tremendous versatility by providing ample spill light for situational awareness without sacrificing long range performance. The Scout Light low profile mount (LPM) delivers unprecedented versatility, allowing the user to optimize the light’s position relative to the rial and other attached firearm accessories. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rial. Constructed of lightweight aerospace aluminum, Mil-Spec hard anodized, and o-ring sealed to keep out the elements, the M640DFT Scout Light Pro is the best performing, most feature rich, light for its size.
