Fenix TK40 High Performance Cree LED Flashlight, Maximum 630 Lumens

TK40 is the first four-core LED flashlight of Fenix, which provide high brightness and long-throwing beam. CREE MC-E four-core LED, max output reaches 630 Lumens, which makes it the world’s brightest AA flashlight. Optimized circuit with large reflector throw 300m (984ft) long lighting beam. Intelligent memory circuitry memorizes last primary output when activating the light. The TK40 produces great power with standard AA batteries. The battery is inexpensive and widely available. This light is suitable for outdoor hunting, exploring, search and rescue, and all other extreme adventures in your life.

Technical Details:
Uses eight 1.5V AA batteries (not included) and maintains excellent constant brightness with two output modes: 8 output types,including Turbo output which can be used whenever high-powered light is needed, exploration, search & rescue, long-range ID
Cree MC-E LED 2 modes with 8 types of output -4 types of primary output: Turbo (630 Lumens, 2Hrs), Low (13 Lumens, 150Hrs), Mid (93 Lumens, 20Hrs), High (277 Lumens, 6.8Hrs) -4 types of strobe: Strobe, Slow flash, SOS, Fast flash

Fenix TK40 High Performance Cree LED Flashlight, Maximum 630 Lumens

The Fenix TK40 is a great tool comparable to a 10 watt search/rescue HID (high intensity discharge) light, but since it is a LED, it is brighter, more efficient, and its multiple light levels make it more functional and more applicable to different tasks.


* EXTREMELY BRIGHT--> up to 630 lumens on turbo mode. However, it also has 13 lumens, 93 lumens, and 277 lumens. This allows you to compromise between brightness and battery life, and to use it for different tasks.
* Runs on inexpensive AA batteries (8 of them), rather than on lithium or 123A's. It can use rechargeable batteries.
* Each intensity (low, medium, high, turbo) has slow flash, fast flash, SOS, and tactical strobe abilities.
* Hard aluminum body, resistant to almost any mishaps you might get this light in.
* Can run on 4 AA batteries if that's all you have.
* The low output is very useful, and it can run for 130 hours.
* Digital regulated output will maintain the brightness stable even when the batteries are low ( will not dim as the batteries become wasted).
* Has an anti-roll design.
* It is waterproof (it was tested by being submerged in 2 meters of water, in which it lasted waterproof for 30 minutes). This means you can use it in the rain without fear of it being damaged).
* Excellent peripheral light and great "throw."
*Includes a nice carrying case, a shoulder strap, wrist lanyard, extra O-rings, and and extra rubber switch boot.


* You can only use the turbo mode for no more than 15 minutes at a time (according to manufacturer recommendations).
* If you use lithium batteries, you void the warranty.
* Batteries are NOT included.
* It takes some getting used to the cycling through the different modes. Read the instructions carefully and practice!
* There is NO momentary-on switch.
* The light is pretty big, bulky, and heavy once the batteries are in. It is probably out of the question to buy a holster for it and hang it from your belt.
* The cartridge into which the batteries are inserted is a bit confusing to use, but fortunately the light has protection so that the LED won't be harmed if you insert the batteries wrong.
* The light is VERY bright, but for some reason it still does not outperform my Pelican 7060 in terms of "throw." The 7060 is rated at only 130 lumens, so it must have something to do with the reflector.

Despite its minor flaws, the PROs outweigh the CONs. The light is a bit expensive though. You would think that for $154, they would at least throw in 8 AA batteries, but they did not. So Fenix, if you are reading this, please include a complimentary set of batteries. Other than this, the light is flawless and its ray of light is amazing, you've got to check it out!
