Build Quality: Very very nice. The flashlight feels solid in my hand. It has plenty of knurling so that even when wet it will be easy to hold onto. The light is smaller then you would expect, being an eight AA light. The flashlight uses a carriage to hold the batteries. When loaded and inside the flashlight there was no rattle. It is rated to IPX-8 waterproof standards to 2 meters (6.5 feet).
Light Output: Wow! Seriously, WOW! 800 lumens in the turbo mode. It won't cook a cheeseburger from across the room but it looks like it could! This flashlight is just stupid bright. It provides an enormous amount of light and throws this light very very far. I was able to illuminate a road sign 400+ yards away. While this is a "thrower" light more then a "flood" light, most practical use will be within 100 yards. This flashlight provides ample spill light so that it can be used for "area" work. If you enjoy seeing what your looking at and not a "wall of white", use one of the lower modes when working up close.
Battery Life: I found battery life to be very good as well. I was able to get over 2 hours runtime on turbo, with usable light for an hour afterwards. Very good considering how powerful the XM-L led emitter is. I am using NiMh AA batteries but the light supports alkaline and lithium disposable batteries as well.
My verdict: A top notch but expensive flashlight. I however find that it was worth the money. Fantastic build quality and insanely bright. I am very impressed with my first Fenix flashlight and would buy this brand again.
What I like;
-Side clicky switch; I'm tired of the rear-clicky on most tactical lights, side is much easier to use
-Nice heft and feel, I like the size
-Great build quality, very solid. The emitter in mine is off-center, but that does not seem to affect the beam
-Incredible thrower! This thing puts out more light on Turbo mode than anything I own, and it is a pretty generous-sized hotspot
-I use Eneloops in it, but I like that it will take AA's if I need to
-Very low mode that is supposedly good for 270 hours runtime.
-On High (as opposed to Turbo) you have all the light you usually will ever need
-Waterproof (tested mine underwater)
-It will light up the night, for a long distance!
-You don't have to mess with the blinky modes if you don't want to.
-Nice white beam at the hotspot. Corona is somewhat greenish indoors against a white wall, but you will never notice that outside.
-Comes with extra "O" rings and a nice lanyard, in a nice plastic carry-case.
What I don't like
-Expensive (but worth it)
-A little tricky on how to get into the blinky modes, but I don't use them so does not matter to me.
This thing will not disappoint you
Some don't like the 8-AA battery holder system but I find it very handy and easy to use.
Oh, did I mention that it's BRIGHT!!!
IMPORTANT: If you use this product, I strongly suggest that you invest in the Maha Powerex MH-C801D charger for AA and AAA batteries and two sets of Sanyo Eneloop batteries - both available on Amazon. This charger charges the batteries properly without overheating them and will give you long battery life. If you need to charge C and D NiMh batteries, get the MH-808M charger.
Although the TK41 has a couple of obvious drawbacks, it's a great light nevertheless. What I like about the light:
1.It uses widely available AA batteries.
2.It's very bright for its weight and size
3.Battery life is very decent compared to the 2AA ones.
4.The deeply grooved textured grip is beautifully machined and is very effective in providing a secure grip, unlike the somewhat ineffective crosshatching found on many other flashlights, including the Maglite.
5.It has decent "throw," and yet the center spot is large enough for comfortable viewing at close distances. There is enough spill outside of the central spot for large area illumination.
6.It has a beautiful braided lanyard.
7.It has effective heat sinking. It has 3 large heat sinking fins built on the barrel where the LED element is. With the 2AA Fenix models, they get really hot in Turbo mode after just five minutes of use, but on the TK41 it barely gets warm to the touch even after 5 minutes in Turbo.
8.The lens is made of tempered glass with an anti-reflective coating. It's supposed to be able to withstand a 3-ft drop on concrete.
What I don't like about the light:
1.It's much heavier and much more unwieldy in comparison with the petite 2AA LD20. This point is in fact giving a bit of buyer's remorse about the TK41. Although I gained a huge jump in brightness when switching from the 2AA LD20 to the 8AA TK41, it comes at great cost in portability.Read more ›
