SureFire M640DFT Scout LED Weapon Light
Situational Awareness and Tactical Strength
The SureFire M640DFT Scout Light is packed with features that put it ahead of its predecessor. This scout light has a far-reaching beam that extends out 533 meters, perfect for long-range scouting from any vantage point. The precision reflector emits 71,000 candela alongside the 550-lumen output to light up the night. It balances long-range performance with ideal spill light that keeps you aware of your surroundings, offering much-needed situational awareness in tactical use.
The light's Low-Profile Mount attaches securely to 1913 and M-LOK rails, and allows you to set the light position in relation to the rail and other added accessories.
Dual-Fuel Reliable
The M640DFT has dual fuel capabilities, for use with the included 18650 battery or CR123A batteries. Thanks to multi-fuel options, feel at ease with the choice of quick recharging or storing power for when you need it most. However, the 18650 does support a longer runtime by just one hour.
