The SureFire M340C Mini Scout Light Pro Weapon Light, part number M340C-TN-PRO, is a compact rifle-mounted LED weapon light in Tan. It produces 500 lumens output and 7,600 candela peak beam intensity from a single CR123A lithium cell, for approximately 175 metres of beam distance.
At approximately 4.1 in (10.4 cm) and 4.1 oz (116 g) the M340C is the smallest light in the Scout Light Pro line, built for short handguards and light builds where a full-size body will not sit comfortably. Runtime is approximately 1.25 hours on one CR123A lithium cell. The low-profile Scout Light Pro mount fits M-LOK and Picatinny rails, and the aerospace aluminium body is sealed to IPX7.
