FENIX TK75 5100 Lumen 2018 Edition 4 CREE LED Flashlight/Searchlight with 2 X EdisonBright BBX3 battery carry cases bundle

Recommended. I wanted a really powerful light for those dark nights when we go camping or houseboating at Lake Shasta and I sometimes walk the dog at night with it just for fun.It is a large diameter tube using 18650 rechargeable batteries. The batteries go into a battery holder that is then inserted into the body of the light. I normally do not like flashlights that use plastic battery holders, but this one is made of good quality polymer and seems well engineered.I bought Panasonic batteries, they have a very good reputation and have more capacity than the cheap Chinese batteries. The Panasonic bats are more expensive, but this is a high quality powerful light and good batteries should be used. You should know that when you get into the use of 18650 batteries there are several things to consider.First, 18650 batteries are essentially industrial grade which means that they are not particularly standardized. The circumference and length can vary, and some have the protruding button on the end and some do not. You also need a good charger. For this flashlight buy a charger that can charge 4 at a time. You can also buy a two battery charger but you'll have to wait longer to charge multiple batteries. The 18650 batteries take a long time to charge, like overnight so I recommend buying extra batteries and keeping them charged as spares.The Panasonic protected batteries I bought are the longest batteries and the Fenix holder accommodated them fine.When you turn this puppy on be prepared to melt eyes. Be careful never look into this light it is incredibly bright and will damage your eyes. The beam is made for throw and does this well, you can light up a mountainside.Finally, I'm a nut. I bought a second battery holder and tube and screwed it on the back of the Fenix TK75, now I CAN MELT EYES FOR A EVEN LONGER. Fenix says you can add up to two more sets of batteries for a longer run time. Yeah!BTW I love the button controls too.

Am I really giving a 1 star review to a Fenix flash light? Yep.As a long time using of a TK41, after loosing my last one, I went for it's big brother, the TK75. The TK75 has the excellent build quality of Fenix flash lights. It's as bright as they say.However, it is a total fail for usability of the two buttons. Nobody at Fenix has handed this flash light to just about anyone and watch them try to use it.Here is exactly what happens if I hand this flashlight for anyone to use.1) If they are right handed, they press the right button with the circle arrow on it. Note that this icon does not say power on, only loop back. So fail on the button icon.2) Pushing this button does nothing. you have to hold it to turn on, but nothing on the button infers to do this. Fail again.3) So they press the next button, this turns it into full brightness and blinds everyone in the room.4) So they press the button again and it turns off. Nobody can see a thing as our eyes have adjusted to the bright light.5) So they figure maybe they can hold the button down and dim it, so they press the right button to turn it on (because that is the button that does something, and the other button does not do anything in this mode), then hold the button down. The flash light goes into strobe mode. Now it's a disco.6) They press the right button again, the disco stops, but it's back to blind everyone in the room mode.7) At this point, the right button will no longer turn off the light. It did before, but not now. The only options are disco and the blinding light. Complete and total failure of this design.8) If the user is determined to make it work, they will press the left button, the flash light goes into ultra dim mode. Too dim to be useful. So they press the right button again, it goes into blind everything mode, then they just put their hand in front of it and block the light.I give this flash light a complete fail as I can't hand this flash light to anyone and have them use it. I forgot what button does what more then once and make the deer think it's a party.Here is how it should work.1) Pressing any button turns it on to it's last setting.2) The right arrow button cycles between all the brightness levels. Hold it down to strobe. Pressing any button turns off strobe.3) Pressing the left button turns it off.Why can't it be this simple? I am going to go looking for my TK41 for my daily use and the TK75 will be night stand duty only.

Wow. That essentially describes this product in one word. This is no mere flashlight; it's a portable photon cannon. This thing delivers amazing output in a surprisingly compact package. On a somewhat foggy night, I was able to easily illuminate trees over 300 yards away. Even the lowest setting is perfectly useable for a variety of tasks. The beam itself is a great mix of throw and flood so, to me, it's a more useful light than dedicated throwers like a TK41 or TK70 (although it will easily out-throw the TK41). It's about 3/4" longer than an LD41 but has a much larger body and head diameter (2" and 3 3/8" respectively). The build quality is excellent as is typical of Fenix lights and the dual power/mode switches are easy to use and work well.The light comes in a plastic carrying case so you won't be able to strap it on your belt or pack by default like some of Fenix's smaller lights. I found that the Maxpedition Mini Rollypoly Folding Dump Pouch works very well as a belt carry option or as a backpack attachment. Personally, I use AW 18650 protected cells (3400 mah) and a Pila IBC charger but any quality 18650 cell/charger combo should perform fine with this light. The carrying case is actually made to accept the Fenix li-ion charger + 4 batteries if you'd like to keep everything in one place.The carabeamer lights that came with my order were pretty much junk but they are essentially free since the price doesn't change if you buy the light without them. You can always harvest the lithium button batteries out of them like I did.If you've been looking for a compact, well balanced, and extremely powerful light, your search is over. Highly recommended.
