Fenix TK45 Review

Fenix TK45 Review

Brand New TK45

Chances are you’ve already read the reviews of the Fenix TK45 prototype that came out around May. So in my Fenix TK45 Review I’ll skip what’s already been covered and focus on the final product as I received it in January of 2011.

Light Source

Producing the light are 3 Cree R5 LEDs the prototypes had used much cooler and slightly less powerful R4 Cree LEDs. When comparing the beam to that of my PD30 with a R4 Cree LED it’s very easy to notice the much more natural looking light from the TK45.

Three Heads

Lowest Setting- 1 LED

I was at first concerned about a video I saw demonstrating the lowest setting and how it rotated to each head. The rotation occurs when the light is turned off then back on again. It doesn’t change while the light is running. It’s very smart as I’d assume that over the LED’s lifespan of 50,000 hours it would ware each LED evenly.

I’d review the three heads to do a beautiful job of combining together. The the medium setting is just about the same as low but with all 3 heads lit up rather than just one.

Battery Shake Review

The batteries do shake which is sad to see in a $150 flashlight. The solution is incredibly easy and yet just as sad for a $150 flashlight. You fix the shake by using 3 squares of toilet paper. If you tightly wrap the carrier up and neatly tuck it into the chamber the shake its completely gone. I just couldn’t handle walking around and having it not feel solid, but this solution has fixed the problem completely for me. It seems that if the tube was another 1 or 2 millimeters thicker the problem would have been solved.

You’ll never throw away a warranty so quickly because you know it won’t be worth the hassle. The warranty is written in poor English and the address to make returns is in China. I’ve heard that Fenix only does warranty service for items purchased through their website leaving me to hope that
I’ll be able to figure out whatever may go wrong in the future and hope that the LED’s live up to at least half of their lifetime ratings.

Sidewinder Buttons Review

The user interface using the sidewinder buttons really is just about ideal. Unlike the protoypes the buttons on the final version of the TK45 have very clearly marked icons to make it clear which cycles the modes and which turns the light on and off and access the strobe modes.

All of the strobe modes are hidden using a double click of the power button after the light has been turned on.

The on button takes to where you were last time the flashlight was on. The cycle button takes you up a notch each time you click cover the well spaced 4 modes of 8, 95, 312, and 760 lumens another click at 760 lumens will take you back to 8 lumens. The only flaw in the UI is that if you turn on the light on the 95 lumen mode in the middle of the light and you only need 8 lumens for what you are doing you’ll be momentarily blinded by 760 lumens before you get to the 8 lumens you wanted.

If your now convinced you want a TK45 now, you can get it at Amazon for under $150 shipped.
