The TK75 LED Flashlight from Fenix is an ultra high-intensity flashlight that uses three Cree XM-L (U2) LEDs for a maximum output of 2600 lumens. Four brightness settings as well as strobe and SOS functions offer versatile usage and a maximum runtime of 200 hours. The maximum beam distance is 1988' (606 m) and an 80º flood beam angle will provide a wide field of view.
The TK75 is constructed of aircraft-grade aluminum alloy with premium Type III hard-anodized anti-abrasive finish and a toughened ultra-clear glass lens with anti-reflective coating and stainless steel bezel. The dual button switch system is located on the flashlight neck. The body on the TK75 can be extended by adding body tube segments and battery holders which will double runtime with the addition of each tube and set of batteries. It is waterproof to 6.56' (2 m) and shock proof to 3.3' (1 m).
The circuitry features over-discharge protection and intelligent memory to return to the same brightness level when flashlight was turned off. The wide surface area of the light head efficiently dissipates heat to minimize light decline. The TK75 is powered by 4 x rechargeable 18650 Li-ion batteries but can run on only two if necessary.
