TK60 or TK70

[bobkat]

I like the TK60 ... looks like it is workable to carry in times when I would like a nice defensive tool .. I would think 800 lumens is enough to blind someone and give time to run or if needed it looks like a nice hefty unit.

The TK70 looks like the head on it is quite a bit bigger? Do you think that will make it more cumbersome to carry around? Do I really need 2k plus of lumens ( want yes.. need not sure )
Plus the price is way to high on the TK70


Where is a good place to buy rechargable NiMh d cells? I got some EverReady but they are only an aa in a D package.

BatteryJunction has a decent charger/d cell battery combo that wont break the bank. Tenergys arent the best but they are ok and more affordable. The charger does ok also . I would go with another dealer for the TK60 though. Theirs seem to all have a coating of dust on the reflector and the tint is pretty green on all levels but high. The Tk60 throws like a son of a gun and output is pretty impressive. Its a big heavy light using all 4 cells . I cant imagine carryng that Tk70 around but it is awesome to look at. A real beast!!

[celler]

Of course, the obvious answer is both, if funds allow. The TK60 appears to be a more practical, everyday or car light. On the other hand, the TK70 would appear to fill the niche of people that want an Olight SR-90 class light at about half the price.

I think the TK60 looks like a more balanced shape with the head size... The TK70 looks a little bit disproportionate. But, having said that, I've decided to wait a Month or so and then get the TK70... because for me, I already have an 800 lumen light (TK35) and I can't pass up the idea of having the equal brightest LED production light out there. I was coveting the SR90, but the TK70 is more affordable, and I'm a fan of Fenix lights. But for security or police work, I reckon the TK60 is a winner!

[bobkat]

TK60 says it can run on three? so do they have a section of the tube that unscrews to do this?
I am thinking with three batteries it would be a good car or camping light (car tent camping) protection light sort of like my three D maglight but with some decent light hehe

That 2200 lumens sounds so tempting... all that POWER
I may wait on that a few months though.. money is a little tight now, but the tk60 is within range

[Rocketman]

The TK60 for sure. The TK70 is not for general use at all, it's a monster. Make sure, though, you buy from a dealer who will give a refund or exchange if your TK60 has issues such as those some have posted.

That's right. See their picture:

What issues? I have not heard of any problems with the TK60.

Just one poster, claiming a lot of dust on the reflector, and a very green tint.

I think some people have disliked the tint. And if I remember correctly, someone may have also had dust underneath the lens (or was that with the TK41?). But others have received great lights.

Edit: Looks like I'm a little (or a lot) late!

[Swedpat]

If TK60 provides the same maximum output with 3 NiMh cells and the only difference is 25% shorter runtime it would be my choice in this case. Then it also would be significantly more lightweight and practical when one doesn't want to carry around a monster like TK70.
But of course: I find both TK60 and TK70 very attractive lights!

[bobkat]

800 lumens I think is still alot of light

Thank you, I have not seen either of those issues in my TK60. I love it. Reminds me of the old 4D Maglite I used to carry on the job, but this puppy is definitely on steroids.

If you think about it, this is probably a problem in the assembly plant and I would expect many lights to have these issues including the switch problems that others have remarked on.

[blah9]

Yes, that would make sense. Hopefully Fenix gets these issues sorted out soon.

They are big on quality so I know they will. Then I will buy my TK41.

[Swedpat]

Anyone who have measured how TK70 performs at 930lm mode with alkalines? Also I am interested about the performance with TK60 using 3 NiMh cells. Same brightness but ~25% shorter runtime?

[DrewK]

I did a runtime test on a TK60 with three 10+ year old 8000 mAh cells (noname green). To my surprise it did not step down from turbo to high. The brightness level was equal to high after 3.6 hours.

The color on mine has some green and magenta outside the hotspot if you look for it. Since these are opposite colors, perhaps it is caused by diffraction? Also the flashlight came with straight deep scratches on the inside of the battery tube, running the full length. Nevertheless I like it with three D cells.

Does anyone know if no stepdown from turbo to high normal behavior?

[CyberCT]

Hmm I thought I read in another thread that the TK60 won't do turbo mode with 3 batteries. But this is good to hear, maybe that other person had crappy NIMHs or something. Can another TK60 owner confirm they also have turbo mode with 3 D batteries instead of 4? What batteries is everyone using? I just bought the Tenergy 10100 model 10,000 mah D cells.

[357mag1]

Unlike what one person stated above the Tenergy D cells have proven to be the best on the market after extensive testing. I would also avoid Battery Junction. All-battery.com seems to have a great supply of Tenergy with the latest cells. In my mind the Tenergy Premiums are the way to go.

The TK60 will definitely go into Turbo with three cells. In fact other than a little testing I never run it with four cells. Here are the tailcap current readings with 3 and 4 cells.

3 Cells
Low 26ma
Med 224ma
Hi 838ma
Turbo 2800ma

4 Cells
Low 21ma
Med 173ma
Hi 626ma
Turbo 2112ma

So using quality 10,000mah cells like the Tenergy Premiums you should get around 3.6 hours of Turbo on 3 cells and 4.7 using 4.

[CyberCT]

357mag1, have you tried the now discontinued blue Tenergy D cells? The ones in the other thread where they could be bought at close-out prices on ebay, I think you were in that thread too. Tenergy says they are 10,000 mah cells but you mentioned that through testing they were more like 8,000 mah but under high voltage draw they were about 8,000 mah.

I have read that for some people the light won't work with 3 D cells, others it will work. So it's down to the battieries.

[joe1512]

Not sure why anyone would want the TK60. It is HUGE but only gives the same output as much much smaller lights. Its also fairly expensive.

A TK41 will give the same output, use the same common cells (8xAAs) and be much more portable and easy to use. Theres also the Olight S65 baton that is in a similar class as is the Polestar A6.


If you are gonna get a monster light, get the TK70! Then you have a truly awesome light with amazing throw and output. You can always run it at the 900 lumen mode and pretend like its a TK60...

-------
Note: I use AccuEvolution 10,000mAh LSD cells with my TK70. It actually runs in Turbo mode (2200 lumens) with only THREE CELLS. I thought this was pretty sweet. Havent tested longterm, but it ran for over a minute in Turbo, so seems to hold just fine.

I'm sure you meant the Blue batteries maintain higher voltage under "high current draw".

Yes the Blue cells work fine. In fact the Blue cells will easily power up the TK70 and work in Turbo using three cells. I don't like the noise that comes from the driver of the TK70 and it is worse in my earlier version, the newer one just kind of hums.

With the TK60 only pulling 2.8amps on Turbo the Blue cells aren't even working. Anybody who couldn't power up a TK60 with three cells either had a deffective unit, dead batteries or crap cells. Even the junk AccuEvolutions can power this thing with three cells.

Worse case senario the Blue Tenergies will give you about 3 hours of runtime using 3 cells in the TK60.

Yes I mean those blue Tenergy D cells.

You were able to run the TK70 in turbo mode with three of these D cell batteries? If I understood your statement as this, that's pretty awesome. Even if I get 45 minutes on turbo instead of an hour. I wonder what the total current draw is on turbo for the TK70 with the 3 D cells, and for each battery?

As for the TK60, 3 hours minimum is great for 3 of the batteries. If I can get a neutral XML swapped in, that would be even better.

wouldn't a TK41 and a knife be easier? LOL

The TK70 will not run turbo on 3cells for more than 30 seconds before it kicks to high.

Wow, I thought you were crazy or had some bad cells. Since I have two TK70s I decided to try both with three cells. My earlier version kicked from Turbo to high after 13 seconds no matter what cells I used. The crap AccuEvolution or the Tenergy Premium. That tells me there is a timer built into the circuitry.

My newer version is still on Turbo with three cells as I write this and it has been over 6 minutes. I don't have the time or inclination to set here and see how long it will run but suspect it will run for at least 30 minutes on three cells.

Total current draw using three Tenergy Blue cells is as follows:

Older TK70 - 9.89amps

Newer TK70 - 10.49amps

I'm betting around 35 minutes of runtime if there isn't a timed kick down to high at some point like my Older version. Maybe Fenix made it 10-15 minutes instead of seconds.

Keep in mind these cells are in series so all cells are experiencing same current draw. In the case of the Newer TK70 that would be around 10.5 amps for each cell.

What is strange is that in some pictures, like in the link below (TK70 review, at bottom shows comparison shots between TK41, TK60, TK70) the TK60 is noticably brighter than the TK41. Any thoughts?

Pictures can be deceiving. I have the TK41 (and another on the way) and if anything my wife and I both think the 41 is brighter than the TK60. It is a very small difference and probably because the TK60 I have tends to lean slightly toward neutral. With the exception of power source connections the heads appear identical. So it could have easily been the other way around and I believe we are seeing variation in individual LEDs.

[CyberCT]

Hmm. The picture does show quite a difference in output though, at least to me. Maybe the camera autoadjusts or something, but still looks like quite a difference. I really wonder if there is an output difference between having 3 vs 4 cells in the tube.
