The Fenix TK51 is a unique flashlight that employs dual LEDs to increase total output, with 16 wide-ranging lighting options. The powerful spot and flood beams include an 1800 lumen maximum output and 425 meter maximum carry distance. For that control, one button instantly turns on the turbo, and the strobe function can be activated even when the TK51 is turned off.

Interestingly, the TK51 can be powered by one, two, or three 18650 batteries or six, four, or two CR123A non-rechargeable batteries. Prolonged use with one or two 18650 batteries will shorten the life span of the rechargeable battery, and the runtime of each brightness level will be shortened when used with CR123A batteries.

The TK51 weighs 430 grams, excluding the battery, and is 188mm long and 48mm in diameter. Utilizes two Cree XM-L2 (U2) LEDs with a lifespans of 50,000 hours, and has a digitally regulated output with a low-voltage indicator. Reverse polarity protection guards against improper battery installation, and the three-button interface is great for fast and convenient operation.
