New Fenix TK75 2015 Model -- 4000 Lumens -- Scratch that, now 12000 Lumens!

Why settle for 4000 Lumens? The LR50R offers you 12000!


The Fenix TK75 Flashlight was a very popular and long-running model. It had multiple versions and lots of upgrades over the years. But it is time for that 4000 lumen flashlight to step down! The new Fenix LR50R Compact Searchlight has taken over as Fenix's resident compact powerhouse. This incredible light features an included rechargeable battery, a lockout function, and is directly USB-C Rechargeable. Forget the 4000 lumens flashlight, it's a old standard. The Fenix TK75 4000 lumens light has been usurped!



The TK75 2015 Edt has been discontinued. Please see above for the most current upgrade.


Wow! Fenix has taken the TK75 from 2900 Lumens to an astonishing 4000 lumens! Look no further if you need a compact flashlight with a phenomenal lumen output as well as beam throw. The Fenix TK75 LED flashlight, with a length of only 7.3 inches, generates a powerful 4000 lumens and is perfect for search and rescue, caving, hunting, or any environment which requires maximum lighting. Imagine a maximum throw of 2,232 (650 meters) feet along with SOS, Strobe, and 4 brightness outputs.
