The SureFire M640DFTNPRO Dual Fuel Scout Light Pro Tan delivers 1,200 lumens when powered by CR123A batteries and up to 1,500 lumens with the included 18650 rechargeable lithium-ion battery, all in a lightweight, compact package designed for demanding tactical, hunting, and outdoor applications. This flagship Scout Light Pro features a new Low-Profile Mount (LPM) that enables precise positioning on MIL-STD-1913 or M-LOK rails, ensuring compatibility with a wide range of rail-mounted accessories while preserving maneuverability. Constructed from aerospace-grade aluminum with a Mil-Spec hard-anodized finish and reinforced with IPX7 waterproof seals, the light is built to withstand rugged environments and adverse weather. The ultra-high-output LED, paired with a Total Internal Reflection (TIR) lens, produces a hybrid beam that excels at both close- and longer-range tasks, delivering reliable illumination where it matters most. Weighing only 5.50 ounces and measuring 5.56 inches in length, it remains highly portable without sacrificing durability. Activation is quick and intuitive via a push-button tailcap switch, enabling fast channeling of light to maintain focus on the mission or scenario at hand, while the SureFire M640DFTNPRO maintains clarity, precision, and confidence in every operation.
