The SureFire M340DFT Mini Scout Light Pro Turbo Weapon Light, part number M340DFT-TN-PRO, is a compact rifle-mounted LED weapon light in Tan. It produces 650 lumens output and 95,000 candela peak beam intensity on the included SF18350 rechargeable cell, for a usable beam of roughly 616 metres.
DFT stands for Dual Fuel Turbo. The turbo head focuses output into a tight hotspot, and the light runs either the SF18350 rechargeable cell (650 lumens output, 95,000 candela peak beam intensity, 45 minutes runtime) or a single CR123A lithium primary (350 lumens output, 55,000 candela peak beam intensity, one hour runtime). Activation is by Z68 click tailcap, the low-profile mount is MIL-STD-1913 and M-LOK compatible, and the aluminium body carries a Mil-Spec Hard Anodised finish with an IPX7 rating.

Frequently Asked Questions
Which rails does the SureFire M340DFT Mini Scout Light Pro Turbo fit?
The SureFire M340DFT Mini Scout Light Pro Turbo comes with a low-profile mount that fits MIL-STD-1913 Picatinny and M-LOK rails directly.
How is the SureFire M340DFT switched on?
The SureFire M340DFT Mini Scout Light Pro Turbo is fitted with a Z68 click tailcap, which gives momentary activation on a press and constant-on with a full click.
How far does the M340DFT throw?
The SureFire M340DFT Mini Scout Light Pro Turbo reaches 95,000 candela peak beam intensity for 616 metres of beam distance on the SF18350 cell, and 55,000 candela for 469 metres on a CR123A primary. Candela measures how tightly the beam is focused and is what determines throw, while lumens measure total output.
How long does the M340DFT run?
The SureFire M340DFT Mini Scout Light Pro Turbo runs for 45 minutes on the SF18350 rechargeable cell and about one hour on a CR123A lithium primary.
Is the M340DFT rechargeable?
Yes — the SureFire M340DFT Mini Scout Light Pro Turbo is Dual Fuel, running a rechargeable SF18350 lithium cell or a CR123A lithium primary as a backup.
