Review Thorfire TK15 S
« on: August 26, 2017, 03:10:28 AM »
This is the Thorfire TK15 S , which is an upgrade to the TK15. I received this light for a really deep discount from Thorfire (99% off) after they had asked me to do a review of the light , No other compensation was recieved.

The TK15 S can be found at……… (link non affiliated)

The TK15 S is an EDC , 18650 powered light with XP-L2 emitter.The light is a pocketable size and reasonably small for a light that utilizes the 18650 cell and both a tail switch and side switch.
The tail switch is used for On and Off and Momentary on only , while the side switch controls the modes of ….
Moon / Low / Medium / High and then with each press once in high mode , the light goes in reverse order with each click of the side switch back down to moon……there is also a hidden strobe which is activated with a quick double click and a bicycle strobe which is activated with a long press. The light memorizes ANY of these modes including the strobe and bicycle strobe , so any of the modes on the light can be put into memory to come on the next time the light is turned on , by simply clicking the light off in the desired mode you want it to come on in next time.

The tail switch is also a momentary or “Tactical” type switch and with a half press it activates the momentary on.
I also tried a variety of cells in the TK15 S and all the cells from protected to unprotected and flat top to button top all work in the light well , other than the longer protected cells can be pretty tight and fully compress both springs it seems , but I had no problems with the light functioning properly even then.

There is 2 step down timers on the TK15 S , with the first one set at 3 minutes , at which time the light steps down to Medium mode. After that mine stepped down again at 37 mintues to the Low mode and remained there until I turned the light off later. (shown in below charts)



Although a smooth reflector is used in the TK15 S the beam is not a really tight beam as a thrower would have , but it does achieve a decent amount of throw for the small reflector , while also having somewhat of a floodiness with it for a good balance of throw and flood. The beam is not defined as you see with a smooth reflector light usually either , it is a more blended beam , but not as much so as the OP reflectors. The tint is a neutral tint just on the warmer end of the neutral spectrum. I would guess it to be in the 4600K-ish to 4800K-ish range as my best guess.

The finish on the light is not a really shiny finish , but at the same time it is not a matte finish either , just kind of a nice sheen to it and a good feel. Overall the finish is very well done though and I found no bare spots or thin spots on the light I received. The tail switch and side switch both work and feel very good on my light , with both switches moving very smoothly and NO fiddling to get anything to work like it should with the switches. The knurling is also well done on the TK15 S and it is semi aggressive but not overly so, with a good feel to it.
The threads at the head and tail ends of the tube are square cut and feel very smooth and also were lubed well when I got the light.
The TK15 S will tail stand , but with the thumb cuts outs you need a fairly level surface for this.

The only bad news so to speak is that if you want to mod this light it will be hard to get apart. I dont know yet just how hard , as I havent tried too much , but it does seem the Bezel is glued and also the driver retainer ring didnt want to move when I tried to loosen it.

Other than that , Overall I like the upgraded TK15 S and feel it is a very well made and useful general purpose light.

NOTE: In the still beamshots segment and in the main video itself , I kept saying / listing “Turbo mode” this light in fact does not have Turbo , but instead is as listed in the above written portion with ……..Moon / Low / Medium and High modes in the main group of the UI.

For those who do not want to watch the whole video , the Still shots and Beamshots start at 6:46 of the video timeline and the outside live footage comparing the Thrunite TC12 V2 and Nitecore EC20 start at 10:59 of the video timeline.
