Description
The M640 Dual Fuel TURBO is SureFire’s answer to the high candela weapon lights on today’s market. The M640DFT runs on one rechargeable 18650 battery or two CR123s. With the 18650, it provides around 2.75 hours of run time while producing up to 700 lumens and 100,000 candela. The M640DFT utilizes the SureFire PRO footprint, allowing the end user to minimize dead space on their gun by swiveling the mount closer to their rail or other accessories. It also accepts all standard SureFire tailcaps and tape switches, along with the aftermarket options available for that system. As with all SureFire PRO lights, the M640DFT comes with a momentary/constant Z68 tailcap and mounts for M-LOK and Picatinny, making this setup ready to roll right out of the box for a large majority of configurations.
