    This is my second of three Fenix lights. This flashlight delivers the brightest light I have ever seen from a unit this small. I bought the set with charger and rechargeable batteries. The entire package is top quality. The charger is the best I have ever had. I can honestly say that all three lights are the best I have ever owned. I am a lifetime Fenix customer.

    I have been receiving your email advertisements for quite Some time. It seems that every time I would like to order a TK75 you are out of stock. Either you never have stock or you sell out too fast. Considering I get your ads often, I find it difficult that you sell out that fast. If you do, your production planner should order more then. Besides, I see you sell them on, but not your own web site. Why is that? It’s the summer months now, I would believe this is an opportune time to sell more. If you could either please get more TK75 flashlights in stock or please eliminate my contact information from your mailing list. Thank you.

    Received it in 3 days. Awesome product. Brightest flashlight I have ever own. I use it to check outside my house whenever there is a random noise. Really bright…..I can see all the way to my back fence. I have a pretty big back yard with chickens. It doesn’t get really hot either. So far I like it. You can tell it is built well when you hold it. Surprisingly not too big either. I’m only 5’6” and it fits well in my hand. Not really heavy either.

    true to specs. Real lumens. I always impress my friends with this light. Love going camping with this. Best Christmas present I ever got.

    This light is incredibly bright and lasts a surprisingly long time using just one extra extension tube and I love that you can screw it to a small tripod if you want to use it as a hunting light , but…
    Why doesn’t Fenix make available various color filters for this light?
    If Fenix would make red and green filters for this light then it would be hands down the best hunting light I’ve ever seen !
    Please start making filters for this light and diffusers for this light as well. You’re missing a huge business opportunity by not being able to market this light as a hunting light for night hunting hogs and coyotes. A lot of hunters would rather have lights like this (capable of being mounted on a tripod and placed at a location different than the hunter ) than to have a cumbersome light mounted on their rifle…

    OK…. time to set things right! I wrote a previous review named 201 5 and this intended to append/edit that review.

    I own both the original and 2015, along with one extension tube.

    So I get the 2015 in…”what? Oh, yes honey… another flashlight, but I got such a great deal!!! ((as if that ever works) and of course the first thing I want to do while having dinner on the couch is fire that bad boy up! So I take the already batteries out of the ext tube, put those in the 2015 and let er rip. It’s BROKE! Nope…. just me getting to know the new buttons… I like the old setup better but… oh damn, the new one is ever so slightly dimmer than the original!?!?!?! Well… I was bummed, mouthed off here on the forum and then gave it a couple of days.

    Tonight I think… it is a dark night, let’s give it one fnal test.

    So… with doubt intact… I fire them up at a couple of big trees a block away and at first I was unsure but after some, OK, a lot of back and forth it turns out that this is a much different LED/or quality/version of light. A) the pattern is wider and more is lit up but most importantly… B) It is much brighter, you can see a LOT more than the original because it is a much warmer light. With this light you just see everything clearer… you don’t get that washed out super bright white that makes it looks like it must be foggy or something. The warmer light is more clear and natural looking and bottom line is, one against the other, you can see more with the 2015.

    I was thinking of returning it but that thought is GONE… all I want to do now is GET GONE camping so I can put it to the test during that “measuring contest” we have with our fellow campers.

    So… my bad on the last review. I tried to edit it but there is no function. Admin is welcome to delete it. If the original in my own words is pure rock & roll…? This is ROCK & ROLL CRANKED TO 11

    2015 model…

    Well… the buttons are not as natural or as intuitive as the previous version which wouldn’t be an issue considering… all we really want is POWER! (right?)

    Well… in a side by side with my original version it actually does not look at bright when on turbo compared to the highest setting on the older one. We are talking a very minute amount of difference but I even switched out batteries just to make sure!

    I only bought for “MORE POWER… huh huh!!!”

    Is it worth every penny spent? Oh yeah… this is a sweet piece of kit but I am pretty disappointed it not only didn’t blow away the old guy… but to have a little of perceptible less???

    Hopefully this review will not get dumped… if it does I will go ape $h1t at Amazon. Maybe something is wrong and it will straightened out and I can edit this.

    We shall see!

    2014 version is pure rock and roll… intuitive buttons, and just plain stupid BRIGHT!!! I bought the extension tube and, well… forget about EVER running out of battery.

    Unfortunately… I am about to go review the 2015 model after doing a side by side.

    (2015 version)
    This light is beyond bright! I live at the end of a long dark road about 900m long in rural texas, and one day just for kicks, I stopped at the beginning of the road at night with my xenon headlights and fog lights on, and just to say that I couldn’t believe that a hand held flashlight was way brighter and reaches further than my lights. Really it’s a miniature sun in your hand.
    Great job fenix!!!!!!

    REVIEW ON 2014 VERSION: This light is the best search light I have perchased:) I take it jogging with me near a trail by house. I counterd a group of thugs one day drinking, smoking and causing a desterbance for the homes in that area. Form a distance of 1000 feet I flashed my TK75!! At them and you should of seen there faces:))) like helpless deers caught in a headlight. They ran sooo fast that I couldn’t stop laughing. Thanks FENIX!!!

    REVIEW ON ORIGINAL VERSION: Incredible all purpose light. The lowest level makes it perfect for daily household use, and the turbo literally blinding. Great for everything from walking the dog to camping. Well made, strong, but surprisingly light.

Not only are you being environmentally friendly by eliminating disposable batteries, 18650 rechargeable battery provides different levels of capacity for your exact need. For example, you can get 30% more capacity out of a ARB-L18-3500 compared to a ARB-L18-2600.

    In addition, Fenix batteries are built with safety in mind. There are built in features to prevent short circuits, design multiple layers of protection and the new button-top design. The high capacity 18650 Li-ion rechargeable batteries each provide protection circuits in the anode to help prevent short circuits, over charge/discharge and over heating. Each battery also includes pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion.
