SureFire M640DFT-PRO Scout Light Pro Tan 600/700 Lumens LED

The SureFire M640DFT-PRO Scout Light Pro delivers exceptional illumination performance with dual output capabilities of 600 lumens continuous and 700 lumens momentary activation. This tactical weapon light combines SureFire's proven reliability with advanced LED technology for professional and civilian applications.

What Makes This Different

The M640DFT-PRO features SureFire's proprietary dual fuel technology, accepting both rechargeable 18650 batteries and standard CR123A primaries without modification. Unlike single-fuel competitors, this flexibility ensures operational readiness regardless of power source availability. The precision-machined aluminum body withstands 5G impact testing while maintaining consistent beam pattern and intensity throughout battery life.

Key Features

• Dual output modes: 600 lumens continuous, 700 lumens momentary with 1.25-hour runtime
• Dual fuel compatibility - 18650 rechargeable or two CR123A batteries
• Mil-Spec hard anodized Tan finish resists corrosion and wear
• Picatinny rail mount with quick-detach lever system
• Precision TIR lens creates optimal beam pattern for target identification
• Momentary and constant-on activation via tailcap switch
• IPX7 waterproof rating for all-weather reliability

Field testing demonstrates consistent performance across temperature ranges from -40°F to +140°F. The precision-engineered reflector produces a focused hotspot with sufficient spill beam for peripheral awareness during close-quarters operations. Remote switch compatibility allows for ergonomic activation placement on various rifle platforms. The robust construction survives repeated recoil cycles on calibers up to .50 BMG.
