SureFire M640DF Scout Light Pro 1200/1500 Lumen Dual Fuel Tactical

The SureFire M640DF Scout Light Pro delivers professional-grade illumination with dual fuel capability, switching between 18650 lithium-ion and CR123A batteries for maximum operational flexibility. This black anodized weapon light produces 1,200 lumens on high with rechargeable batteries and 1,500 lumens with primaries.

What Makes This Different

Unlike standard weapon lights limited to single battery types, the M640DF Scout Light Pro accepts both rechargeable 18650 and disposable CR123A batteries without adapters. The TIR lens creates a focused 400-meter beam with optimized spill for close-quarters identification. SureFire's proprietary electronics automatically adjust output based on battery type, ensuring consistent performance across power sources.
