The SureFire M640V-B-PRO Scout Light Pro delivers dual-spectrum illumination with 350 lumens of white light and 120 milliwatts of infrared output in a single tactical package. This weapon-mounted light system provides operators with seamless transition between visible and IR modes without compromising mounting position or requiring additional equipment.
What Makes This Different
Unlike standard weapon lights that require separate IR devices, the M640V-B-PRO integrates both visible and infrared LEDs in one compact housing. The dual-output system eliminates the need for multiple accessories while maintaining SureFire's reputation for combat-proven reliability. The 350-lumen white LED produces a focused beam with significant spill for close to medium-range target identification, while the 120mW IR output provides effective night vision device compatibility at tactical distances.
Key Features
- Dual-output system: 350 lumens white LED and 120 milliwatts infrared LED
- Mil-Spec hard anodized aluminum construction with Type III black finish

Field performance centers on the light's ability to maintain zero through recoil cycles while providing consistent output across temperature extremes. The switching mechanism responds reliably under stress, with tactile feedback that works through gloves. The integrated rail clamp system maintains secure attachment on rifles, carbines, and shotguns without shifting under rapid fire sequences. Battery contacts resist corrosion in humid environments, ensuring reliable function during extended operations.
