The SureFire M640DFT Scout Light Pro is the full-size turbo in SureFire's Scout line — built for shooters who want maximum reach and longer runtime than the mini M340. Its turbo head focuses output into a high-intensity beam of 100,000 candela and 700 lumens on the included SF18650 rechargeable cell, throwing usable light out to around 632 metres.
"DFT" means Dual Fuel Turbo: the SF18650 rechargeable delivers full output and up to 2.5 hours of runtime, or you can run two CR123A primaries as a backup. The low-profile mount fits M-LOK and Picatinny rails, and the aerospace-aluminium body carries an IPX7 weather rating. UK-stocked for fast dispatch.
Finish: Black — also available in Tan.

Frequently Asked Questions
What does "DFT" / Dual Fuel Turbo mean?
Turbo refers to the focused, high-candela beam; Dual Fuel means it runs on either the included SF18650 rechargeable cell (700 lumens / 100,000 candela) or two CR123A primaries (350 lumens / 65,000 candela).
How far does it throw?
Up to 100,000 candela for an effective beam distance of roughly 632 metres on the SF18650 cell.
How long does it run?
Up to 2.5 hours on the rechargeable SF18650, or around 1.5 hours on CR123A primaries.
How does it mount?
Via the low-profile Scout Light Pro mount, compatible with M-LOK and Picatinny rails.
M640DFT or M340DFT — which should I pick?
The full-size M640DFT offers more output and longer runtime; the compact M340DFT mini is lighter and lower-profile for a slimmer carbine setup.
