SureFire M640DF Scout Pro Dual Fuel Weapon Light

The SureFire M640DF Scout Pro: Legendary Performance, New Versatility

The Dual Fuel Scout Light Pro represents the evolution of SureFire's combat-proven Scout Light system. This rifle-mounted weapon light combines proven reliability with innovative mounting flexibility, making it an ideal choice for shooters who demand performance across close-to-long-range applications.

Power and Output

The Scout Pro's ultra-high-output LED is virtually indestructible and delivers exceptional brightness:

• 1,500 lumens with the included SF18650B rechargeable lithium-ion battery
• 1,200 lumens with two 123A lithium batteries

This dual-fuel capability gives you flexibility in the field—use rechargeable batteries for training and extended operations, or rely on standard 123A batteries when you need maximum shelf life.

Intelligent Beam Design

The Total Internal Reflection (TIR) lens creates a hybrid beam pattern that balances reach with surrounding light. You get enough intensity for distant target identification without sacrificing situational awareness at close range. This makes the Scout Pro equally effective whether you're clearing a room or engaging targets downrange.

The Low-Profile Mount Advantage

SureFire's new Low-Profile Mount (LPM) is a game-changer. Unlike traditional fixed mounts, the LPM allows you to optimize the light's position relative to your rail system. This flexibility means you can work around other accessories—optics, backup sights, or other rail-mounted gear—without compromise. The mount securely attaches to any MIL-STD-1913 Picatinny rail or M-LOK slot.

Built to Last

Constructed from lightweight aerospace aluminum and finished with Mil-Spec hard-anodizing, the Scout Pro is engineered for durability. O-ring sealing keeps out moisture and debris, ensuring reliable operation in harsh conditions. The recoil-proof design handles the punishment of serious shooting without degradation.
