Re: Diffrence between Fenix TK11 R2 And Q5

Some TK11s seem regulated on 18650 but it's not specific function but low Vf emitter. TK11 R2 with higher Vf will run DD.
 
Balls. They sent me a TK10 instead. I emailed Fenix-Store so we'll see what's up. I hope they've still got the TK11R2s in stock.

Ouch, sad to hear they shipped you the wrong light by mistake. Fenix-Store / 4sevens has an excellent reputation of customer service though, so I am sure they will make it right as soon as they can. 🙂
 
The Fenix-Store sent me a TK10 instead of the TK11 R2 I had on order too. It came in today and I immediately informed them of their mistake. They said they shipped out the TK11 R2 today. I wonder why they had such a mix up?
 
Well, I suppose the TK10 and TK11 look similar enough that a person could easily mistake one for the other. :shrug:

Speaking of getting a TK11 R2, in a brief but intense moment of weakness I bought a TK11 R2 at a local brick and mortar store earlier today. 😛

Any runtime test proving that? So far I've measured runtime of two TK11 R2s and both were flat regulated with 18650.
 
Re: Diffrence between Fenix TK11 R2 And Q5

If you put low Vf emitter to TK11 Q5 it's going to be flat regulated (on 18650) as well.
 
I sure hope that the R2 version is regulated on a 18650 as this is the only thing keeping me from getting one.

I did see a small difference is the description between the Q5 and the R2 models.

The Q5.

Turbo Mode: 225 Lumens
2.7 hours (one 18650 Li-ion battery)
1.5 hours (two CR123A batteries)
The R2.

Turbo Mode: Constant 240 Lumens
2.7 hours (one 18650 Li-ion battery)
1.5 hours (two CR123A batteries)
The R2 version says Constant brightness on Turbo where as the Q5 does not.

Could be a typo though.

Maybe 4sevens could chime in here and tell us for sure??


Mike.
 
If it really does have flat regulation with an 18650, It would probably have to be circuitry. If it was a lower vf, then wouldn't it basically be running in direct drive once the battery volage lowers? Don't 18650's get lower then the voltage required to run any bin of LED when they are running out of charge?
If you are saying that it only has a buck circuit, then it can't have flat regulation, unless R2 leds only need about 2.7 volts, which i seriously doubt.
It would need to have some sort of boost circuit for flat regulation.
 
Re: Diffrence between Fenix TK11 R2 And Q5

Thanks for the help guys! Since I don't have any plan to use 18650 batteries I've just ordered the Q5 version with 10 extra batteries.
 
No, you're incorrect. Li-Ion is almost empty @ 3,5V. With low Vf (~3,2-3,3V@1A) there's still 0,2V difference -enough for buck circuit. At lower voltages it goes DD but battery is empty - it doesn't take long (~30minutes according to jirik's graph) but there's no sudden death which is a +.

Hmm, that's strange that the same thing happened to you too.

Maybe the lights are being packed by a new hire who can't tell the difference between the TK10 and the TK11! :shrug: 🙂

Anyway, does anyone know how the return process works? I've never had to do it before...
 
If you were to carry the TK11 in your front jean's pocket, how easy would it be for the light to come on and how comfortable would this carry be (assume tac ring is removed)? Thank you.

Stress Test, as far as returns go, I ask them to send me a self addressed prepaid envelope with the TK11. That way all I would have to do is drop the TK10 in their envelope and send it back. I didn't think it was fair that I would have to make time to get to the post office for their mistake. They were very nice about it and said they would. I'm thinking I should get the order monday or tuesday. So we'll see. So far 4sevens has been great. I understand mistakes happen.
 
Re: New Fenix Inbound! (TK11 R2)

Well, I got my TK11 R2 in about an hour ago and I am really loving it so far! I had the 18650 batteries already bought (thanks fast shipping, Lighthound) and actually received the light really fast (thanks again, Lighthound).

I am still waiting on the 18650 charger I order (thank you for slow shipping DX) so I am not sure how charged up the 18650 I got here now is. Not had time to buy a DMM yet, still trying to figure which one to buy to simply test my batteries.

But, I LOVE the 64 "regular" lumens that I will use for everyday duties, and then the BAM! in your face, turbo mode, that I can switch too. I love the momentary switch also. I currently carry a P3D and it has never failed me, but I wanted to get into a rechargeable light with a bit more "oomph".

I had bought a smooth replacement ring for the "cigar" ring, changed it out and to be honest? I changed it back. I want to try the "cigar" out for a bit, as I feel I can hold onto it better (one of the reasons I wanted to upgrade my P3D - a bit small, smooth and hard at times to hold onto).

The case that came with it will actually suit my purposes very well (for now). I can carry the light bezel down and it fits great, even with the "cigar" ring on it. I will decide later if I need to consider a different holster, but I think this one is fine for now.

This thing is solid, feels great in the hand, more "stout" and just makes me feel like I have a quality light in my hand. I can't wait to try it out on the streets. My P3D will not be un-used, if not used as a back-up carried in the PD car, I will put it in my truck in case I need it.

Anyone on the fence about the Fenix TK11 R2, I tell you...buy it! Between the two (Q5 or R2), simply go with the R2. It's not but a few dollars more, so just get it. I am really stoked about this light, it was worth the wait!

Oh, and kudos to Lighthound for my recent few purchases (batteries, TK11, TK11 ring, etc). Fast delivery, awesome CS (the times I called them) and simple to use. I just wanted to share this with you guys, because I know that reviews help people make decisions easier.

Not at all. Most of us have a light wishlist that never ends... :grin2:

Although I have a Surefire weapons light on my AR-15, I still would love to have a Surefire to carry. I have been looking at the G2ZL, but I think that the shape of my TK11 kinda takes care of that "idea". What I really, really, really want is the Surefire E1B, but for about $150? Wow! Better start saving! :thumbsup:

The Surefire E1B is a bit Overpriced. You could get the Romisen RC-N3 for about $25 from Shiningbeam.com and run a RCR123 rechargable in it. It has a forward clickie and is pretty simular to the E1B at about 1/6 the price and can be used with AA batteries with the extention tube. If you are a police officer or independantly wealthy then the Surefire E1B may be worth the money to you. Personally I would choose the E2DL over the E1B if I were going to buy a Surefire. Have you considered the RA Clickie?

Don't I know it!

And yes, I have actually looked at the Romisens ALOT, and would still like to buy one of those. I just could not ever figure out which one to get. I would really like to add a Romisen to my collection as well soon.

I will check out those you mentioned. Of course, I would have to look into getting into rechargeable 123s and a charger, etc. I bought the TK11 for the 18650 and bought my wife a light off DX that also uses a 17650, for the simplicity of it all.

Guess I will have to face the reality of branching out in batteries and such! :grin2:

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