SureFire M340DFT Mini Scout Light PRO


Video | What’s Included | Specs | Pictures | FAQ | Restrictions | Related Info

The M340 TURBO is SureFire’s answer to the high candela weapon lights on today’s market. The M340DFT runs on one rechargeable 18350 battery or one CR123 (at reduced output). With the 18350, it provides around 45 minutes of run time while producing up to 650 lumens and 95,000 candela. The M340DFT 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 M340DFT 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.

Should I get the M340DFT or the M340C?
It depends on what you want from your light. Do you want more flood and less hotspot? The M340C is your best bet. If you want an adequate amount of flood with a bright hotspot for more range, the M340DFT will fit your needs.
