The TK75 LED Flashlight from Fenix features a three Cree XM-L2(U2) LED emitter array producing a maximum output of 2900 lumens. With four output levels, starting at 25 lumens, the amount of illumination can be tailored to any situation. An intelligent on/off switch remembers the last brightness level used, so the next time it is turned on, it automatically goes to that output. There is a 2900-lumen instant-on strobe mode for blinding or disorientating. No matter what output level the flashlight is on, or if the light is turned off, press and hold the cycle button to turn on the strobe feature. For emergency signaling, a 450-lumen S.O.S. mode can be activated. When turned on, the light automatically and repeatedly cycles through the Morse-code S.O.S. sequence so you don't have to.
The aluminum flashlight body has a Type III hard-anodized black finish with an anti-reflection coated and impact resistant glass lens. A grid-type textured handle provides an anti-slip grip in cold or wet conditions. It is waterproof and submersible to 6.6' for up to 30 minutes and impact resistant to falls of up to 3.3'. It runs on four 18650 li-ion batteries, with over-discharge circuitry to protect the batteries, and reverse-polarity protection which prevents damage to the light if the batteries are installed incorrectly.
