Overview

The SureFire M640DFT-PRO Turbo Scout Light Pro represents SureFire's maximum-throw weapon light solution, delivering 700 lumens with an exceptional 100,000 candela peak beam intensity for positive target identification at extreme distances. Unlike flood-oriented lights that prioritize raw lumens, the Turbo variant uses a precision reflector to concentrate light into a tight, far-reaching beam capable of illuminating targets out to 632 meters. This makes the M640DFT-PRO the ideal choice for users who need to identify threats at extended ranges, particularly when paired with magnified optics or operating in open terrain.

The dual-fuel design accepts either a high-capacity 18650 rechargeable battery for 2.75 hours of runtime or two CR123A batteries for 1.5 hours, providing operational flexibility for extended missions or emergency backup power. The proprietary TIR lens shapes the beam into a focused center spot with controlled spill, allowing users to maintain peripheral awareness while projecting maximum throw downrange. At 5.2 ounces, the M640DFT-PRO balances weight efficiency with the robust construction SureFire is known for.

Built to SureFire's legendary quality standards with aerospace-grade aluminum and mil-spec hard anodizing, the M640DFT-PRO withstands the punishment of hard-use carbines including full-auto fire. The light integrates seamlessly with SureFire's ecosystem of Scout mounts, tape switches, and accessories, allowing users to configure their setup precisely to mission requirements. For military, law enforcement, and serious civilian users who demand maximum throw performance, the M640DFT-PRO sets the benchmark in its class.
