With its four-core LED bulb and 630-lumens brightness, the Fenix TK40 high-performance flashlight is ideal for outdoor hunting, exploring, search and rescue, and a host of other extreme outdoor adventures. The TK40--the world's brightest AA flashlight--is equipped with a Cree MC-E LED bulb with a lifespan of 50,000 hours. The bulb provides an extremely bright long-throwing beam that extends for up to 984 feet, plenty long enough to light the path ahead. The TK40 also produces four output levels: turbo (630 lumens), which runs for up to two hours on a set of eight AA batteries; high (277 lumens, 6.8 hours); mid (93 lumens, 20 hours), and low (13 lumens, 150 hours). As a result, users have plenty of lighting options for any scenario. Users can even use the light as a strobe, with four strobe settings: strobe, slow flash, SOS, and fast flash.

The flashlight is also well built, with a durable aircraft-grade aluminum body coated with a premium Type III hard-anodized, anti-abrasive finish. The construction--which also includes a toughened ultra-clear glass lens with an anti-reflective coating--helps the light hold up to all kinds of abuse. Other features include intelligent memory circuitry that memorizes the last primary output when activating the light; a digitally regulated output; a pushbutton tail cap switch; and such accessories as a shoulder strap, lanyard, rubber switch boot, and two spare O-rings. The TK40, which also stands on a flat surface to serve as a candle, carries a limited lifetime warranty.

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.

PROs:

* 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.

Cons:

* 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.

If you're looking for the brightest flashlight around (and a very fun toy), this is it. I did extensive research on the what people felt was the brightest flashlight on the market. There were no reviews for this one because it's brand new, but with a lumen rating of 630, how could you get anything brighter. So I bought it and I've never regretted it. It has 4 settings and the lowest setting is about equivilant to my 4D maglight. The 2nd setting outshines my 120 lumen Dorcy. The amazing thing about the stream on the highest setting is that the light doesn't disipate with distance, as most other lights do. For example, I pointed it at a stop sign about 800 feet away and it lit it up like a christmas tree. I don't know any other flashlight that will do that. We took it camping recently and put it up against my 1M candlelight spotlight, and my suburban's high beams and it out-shown both. Amazing!

Other notables, it runs off 8AA batteries, but will operate off 4AA batteries with no decrease in light. It has 4 settings, with 4 corresponding strobe functions. The batteries will die on you after about 2 hrs constantly on high, but they'll last for weeks with normal use on the 1st, 2nd, or 3rd light settings. It advertises that it's completely submersible to 8 feet, but I'll never do that. It is good to know that it will most likely be perfectly fine in a rain storm though. As far as size, it is a tad big and heavy for a tactical, but I absolutely don't mind. It feels solid and unbreakable and I like that.

I love this flashlight. Do I need a flashlight of this magnitude, no. Fun to play with though, absolutely. Worth the money I spent on it. . . I don't know. I suppose it depends on how much you have and are willing to spend. If you simply want the brightest AA flashlight on the market however, this is it.

This flashlight is the brightest light I have ever used. It puts any stock Mag Light to shame, and most other flashlights out there. If you want something to light up the night, this is a great choice.

What attracted me to this light was the fact that it could run on 4 AA's or 8. I didn't want to bother with special lithium batteries or the 123 cells. This light is extremely bright for a AA light, and no words can describe it, you have to see it in person. It has low, medium, high, and turbo. I find that medium is a good all-around setting and leave it on that until I need to really light things up with turbo.

Overall it's an amazing light, something you need to try to believe, you won't be disappointed.

I'm an enthusiast about flashlights and coolers. There are several things that I look for when considering a flashlight. 1) Only flashlights that use AA or AAA batteries are considered. Those two batteries are the cheapest and most readily available batteries. Plus, in an emergency, I do not want to be scrambling for different types of batteries (C, D, 9V, CR123, or any other type of specialized battery). 2) The design has to be shock resistant and waterproof. 3) The longest battery life in proportion to the output. I would like an efficient flashlight. 4) Best combination of durability in ratio to size and weight. This is a review of the Fenix TK40 with a CREE MC-E LED with a maximum output of 630 lumens. It is rather long, so if you want the short of it, skip to the conclusion.

Brightness: The low setting of 13 lumens is slightly brighter than flashlights with Nichia LEDs and having better throw. The runtime is estimated at 150 hours on low. The medium setting of 97 lumens is very powerful, enough for just about any use, including lighting up a room, and has a runtime of about 20 hours. The high of 277 lumens with a runtime of about 6 hours appears slightly brighter than the Fenix LD20 on turbo. The turbo mode with 630 lumens is considerably brighter than the LD20 and the output readings are equivalent to a 10 watt HID spotlight. Took it outside and it performed like a spotlight. Indoors, I could shine the flashlight up at the ceiling and it lit the living room like a ceiling light. It appears that this is truly the brightest flashlight running on AA batteries, which is great as I only consider products that use AA and AAA batteries. The only brighter flashlights are usually the high-power HID lights that use special batteries and have short runtimes.
