Surefire M640DFT-PRO Scout Light Pro Tan 600/700 Lumens White LED Weapon Light

The SureFire M640DFT-PRO Scout Light Pro is a high-output, dual-fuel weapon light built for long-gun platforms and engineered around SureFire's Turbo reflector for an exceptionally tight, far-reaching beam. Finished in Tan and machined from aluminum, this Scout Light Pro delivers 700 lumens of white LED output when powered by the included SF18650B rechargeable battery, or 600 lumens when running on two CR123A lithium primaries - generating 100,000 candela for the farthest-reaching beam and longest runtime of any SureFire long-gun Weapon Light.

Measuring just 5.9 inches long and weighing only 5.5 ounces, the M640DFT-PRO keeps the front of your rifle light and agile. The versatile Low-Profile Mount (LPM) allows the user to optimize the light's position relative to the rail, and it is compatible with both MIL-STD-1913 (Picatinny) and M-LOK rails right out of the box. A push-button tail-cap switch provides intuitive momentary and constant-on activation, and the rugged aluminum body is sealed to IPX7 waterproof standards, submersible to 1 meter for 30 minutes.

Runtime is rated at up to 2.75 hours on the included SF18650B, giving you extended illumination for sustained use. With a head diameter of 1.258 inches and SureFire's proven build quality, the M640DFT-PRO Tan is a purpose-built illumination tool for AR-15s, scout rifles, and other long-gun platforms where beam distance and reliability matter most.
