Fenix TK11

Ok, I found out some more info.

I sent a E-mail to Fenix and asked them about the R2 being regulated, and if it had a different circuit then the Q5.

Here is what they said.



Hello Mike
Thank you very much for your attention to Fenix light.
Actually, TK11 R2 and TK11 (Q5) use the same circuit, they are just with different LED about the component, and they have the nearly same circuit graph no matter use CR123A or 18650 battery. Due to the individual difference, some will have more flat regulation.

Best regards!

So it appears the Phantom23 was correct about "regulation" being because of the lower Vf of the R2.




Mike.

The Ultrafire WF-139 will charge all the batteries you mentioned and is very affordable. I got mine from 4Sevens.

I actually already have a single 18650 battery charger on order (DX takes forever though). I meant to say wife's will use 18650, not 17650.

I think I am really wanting to get the Pila IBC charger though. Seems to be a really good one for a good price.

Have you considered the RA Clickie?

I honestly was not familiar with this until you mentioned it. Went to look at it and need to read some more on it. Still not sure yet what the deal is with it, but will find out. :thumbsup:
 
An update to my earlier post:

I got the correct TK11 R2 in the mail today, and it looks and works great! 😀

Fenix-Store did include a return envelope for the TK10, so that'll be easy to send back.

And, to top it off, my 18650 batteries and charger shipped today! :twothumbs

I tested out the light with 123As, but I won't actually be using those in most circumstances.

On a side note, I also ordered the red filter for the TK series lights. I figured it'd be good for when I carry the light in a pocket, to keep stuff off of the lens (and I'm paranoid about lens scratches so it'll be good protection too).

This week just got a whole lot better! :laughing:
 
I got my Tenergy 18650s in today. They came uncharged but I test fitted one of them into the TK11. It's a really tight fit! Getting the battery out again takes some hard shaking. These are rated at 2600 mAh so maybe they're a tad bit fatter than some of the lower capacity 18650s.

The other thing I didn't like was that the positive end is flat. Fortunately it seems to still make good contact in the light, but it'd be easy to get the cell reversed if you were trying to install the battery in the dark (if you had to reload).

There's a battery store in my town that I'm going to check out sometime; they may sell 18650s.

Funny you mention this, cause in a other thread someone reported putting CR123A into it makes the whole thing rattling... I thought for the TK serie the tube has been slightly widened to make 18650s fitting?
But I am still waiting for my TK11 R2 from 4sevens, so i can't reconstruct this...:popcorn:

Btw. do you would recommend these Tenergy batteries for the TK? To date i was very much into primarys but now i think about switching to rechargeables but don't know anything about 18650 and its chargers...
 
I just received a Fenix TK11 R2 from 4sevens yesterday. Overall, I am very happy with the light. It's bright, as it is very close to my EagleTac T10L and Surefire 6P-M60 in overall output. Plus it has amazing throw for it's size, and the R2-bin has perfect tint!

Overall for the price-to-preformance ratio, I give this light A++!
 
^^^+1 on that the new R2 is improvement, TK 11 is an amizing light. That being said, i gotta give to Olight M20 Warrior Premium, it has a low and a strobe, replaceable reflector (OP or SMO), holster that comes with it worlds better than the on that comes with TK 11. Plus Olight M20 throws like mad.

I put in some 123A to start, and they are pretty loose in the tube. Other people have reported rattling, but I didn't really notice anything (not that this kind of issue would bother me though).

My impression of the Tenergy stuff is, well, it seems somewhat cheaply made. But it WAS cheap after all, just $35 for both 2 batteries and charger. The charger seems very fragile and lightly built. But that being said, I just got these items yesterday so I haven't owned them long enough to make any judgements on reliability.

The other thing is that you'll have to be very careful about the polarity with these cells and charger, because to me it looks like the cells go in the charger upside down or "backwards" from what you'd expect.

But if these things are really 2600 mAh then I can forgive a few of the flaws! 😀

The only light in your signature that I don't have, yet, is the M20. I plan on picking one up sometime in the near future, especially with the new tint that they are coming with from batteryjunction.

I have only had my TK11 for a day now. So far, it's awesome. Fenix put together one heck of a light for the price. Build quality is top notch, you can tell this thing would take quite a beating. Output is also very high, as is the throw with the smooth reflector. I just can't say enough about this wonderful light, makes me mad that I didn't buy one sooner :grin2:

Anyone have a pic of a black TK11 with the orange switch cover installed? Just wondering how she looks with it...

I'd recommend these cells. They're protected despite the blue packaging, nice and small, and labelled as a high capacity. What more could you want?

this charger is pretty good as well.

On top of this, can anyone tell me how to change to the Orange switch cover? do I need a special tool? Yes I am new to this type of thing! I have just received the R2 and I'm quite impressed, compared to my other lights anyway which are SF-L4, P2DCE, and a Milky M274.

Many thanks

If you unscrew the tailcap, you see a ring with two small holes. Use any tool that fits and unscrew that ring. The rest becomes obvious. Just pay careful attention to the order and orientation of everything that comes out, because it has to go back in in reverse.
 
Thanks for that, it was a bit tough to turn but did it eventually!
Here are a couple of pics, sorry about the quality.

Are there any available tailcaps for the TK11 that would allow it to tailstand?

Its very handy/bright light but not being able to tailstand makes it not so good when working.
