Fenix TK51 is a dual LED, 1800 lumen high output outdoor flashlight featuring 2 x Cree XM-L2 LED's. TK51 features both wide area flood and long reaching (425m) beams which are individually adjustable for output up to a maximum of 900 lumens each, for 16 output combinations. The TK51 uses 3 x 18650 Li-ion or 6 x CR123A lithium batteries. (1 or 2 x 18650 or 2-4 CR123A batteries can be used in an emergency)

Instant Strobe and Turbo modes can be activated with a single button press when the torch is switched off, and the intelligent memory function remembers the last used lighting level for each LED.

Fenix TK51 also features built-in overheat protection, reducing maximum output until the torch has cooled in order to protect the LED's and electronics.
