The TK40 is the latest installment in the TK-Series and is the first Fenix to use Cree's MC-E quad-die, very powerful LED. Powered by eight AA batteries and boasting 630 lumens of output, the TK-40 is the ultimate portable, long-range illumination tool for the backpacker, explorer, and flashlight lover.

The TK40 is the world's brightest, AA-powered flashlight. Its optimized reflector enables it to throw a wall of light for over 300 meters. All of this luminosity is sealed tight in a waterproof, durable, and strong aluminum body that measures in at just 208mm long.

The TK40 has two different modes of output, each with four different levels - a total of eight different outputs.

• Its primary modes are constant-on: Turbo (630 lumens), Low (13 lumens), Medium (93 lumens), and High (277 lumens).
• Its secondary modes are strobe/flash: Strobe, Slow Flash, SOS, and Fast Flash.

The TK40 also has intelligent circuitry that will memorize your last-used primary mode.
