Re: FENIX TK11 R2 NEW UPGRADED EDITITION!

I can't speak about the centering of the LED, but I believe with respect to regulation, your phone is indeed ringing. 😉

Thank you for the info!

Re: Fenix TK11 R2 new upgraded edition!

Well from what I've read on these posts some people like to use night vision goggles and have their eye adapt to the low light level. By not having a low "low" setting these tactical people experience their eye always adjusting and that's inconvenient.

There is a red filter available for the TK-series. I suppose it can be used in situations where you don't want to impair your night vision.

Re: Fenix TK11 R2 new upgraded edition!

MMMmm, but is or not 18650 regulated?, that is the question. I see commentaries in both directions :thinking::thinking::thinking:

IM planing buy it , I live in Chile South America, I need to know what batt buy in Hong Kong.

I have already TK20, IM very happy with it and I want tk11r2 to use all accessories in both flashlights, the pressure pad is really cool ( lose some brigtness using it due to i think poor contacts and cable, but works fine in mid ranges) .

Thanks!

It is regulated on 18650's.

Re: Fenix TK11 R2 new upgraded edition!

Why a lot of people say is not regulated in this forum ??? despite the evidently graph! ...is only the low vf ( I don't know what is that) says the thread...

Yes I got the filter , that is the purpose and added with the normal mode, can low at least 50% of the power without disturbing your natural night vision.

short TK11 question

Hey all,

My question is,,,,,,,,,,,,Is it bad for my TK11 R2 to leave it in my car on a hot day? Sometimes it stays in there all day and it can get up to 100 degrees.

Is this bad for the light?

Thanks!!

The newer revised R2 version is regulated on 18650s whilst the original Q5 version is not regulated well on 18650s.

Re: FENIX TK11 R2 NEW UPGRADED EDITITION!

Yeah, 6 lumens of difference is really tempting... Man, these Fenix fanboys make me prefer to hang around Blade Forums...

1. its more like 6% difference between r2 and q5 than 6 lumens. soo... one way to look at it is they could take one area of the beam, such as spill, and increase it 12% while keeping the throw the same. by attempting to divert the increase in throw to the sides by lightly stippling the bottom half or third of the reflector. hmmm... not that they did that, but just a thought.

2. we'll miss you :nana:

Heat will have more of a damaging effect on the batteries than the light itself. 100 degrees should do no harm, but the temperature inside a car left in the sun can get a lot hotter than that.

I'll merge this thread with the main TK11 one.

Re: Fenix TK11 R2 new upgraded edition!

Is there such a thing as a "cover" for the threads that are exposed when you take the "anti-roll" ring off? (looks kinda cheesy)

sorry if this questions already been asked.

Thanks for the help!!

Yes, they are available from The Fenix Store or Lighthound.

Re: Fenix TK11 R2 new upgraded edition!

I got my TK11-R2 today! 😀

Fantastic light! The head sucks, really ugly with the two rings, but inspires toughness. The whole light feels tough, tougher than my TK10.

I use it with primaries, as all my lights, but those rattle in the tube if you ahake the light. By now, I wrapped some paper around the cells, but I wonder if there's a better solution? Please don't tell me to use an 18650...

I thought about the battery magazine of the Olight M20 Warrior, but that one doesn't work, even if you would cut of the U on top.

I also compared the light to the M20-R2, equipped with an SMO reflector. The Olight has a tighter hotspot and it is brihter as well of course. I preffer the larger hotspot of the Fenix, and I also preffer the UI. The Olight is more versatile and probably the better constructed light, but I just like the simplicity and the toughness of the Fenix! 🙂

I would resume it this way : If you want a versatile light which also offers you more modes, get an M20. If you own several lights and you just want a tough trower, get the TK11!

Greets,

Henk

It has wider tube because 18650's are wider. And they ARE better solution - 18650 fits perfectly and gives long (slightly over 2:30h) runtime and constant output.

It is brighter only in the hotspot or has more overall output? Most people see the hotspot to define how bright a flashlight is... Can you do a ceiling bounce please? 😀

I'm having hard time deciding between these two lights, the fenix is better regulated, cheaper and tougher but the M20 throws better and comes with better accesories.

Re: Fenix TK11 R2 new upgraded edition!

Well I don't know if this light got a warm reception at CPF or not, but somebody's buying them apparently.

I was ready to order one from 4Sevens and found out they're out of stock! 😳:mecry:

Re: FENIX TK11 R2 NEW UPGRADED EDITITION!

I've a Tk11.
I don't understand what "regulated" means... hasn't the light a "Digitally regulated output - maintains constant brightness????

I use a 18650.... is better to use it or 2 cr123?? I didn't noticed any differeance

Sorry for the noob question...

Look at the chart in this review. The vertical scale is relative output and the horizontal scale is time. Notice how the red line (18650) slides down meaning as time goes on, the output slowly drops. It's not that noticable, and lights that do this usually have great runtimes, but you are not getting the advertised lumens for very long at all. The TK11 seems to do much better with the CR123s and the RCR123s, however.

Their digitally regulated claim seems only to apply to the dual cell setup and not the single 18650. Evidentally it's a challenge to design a regulation circuit when you try and accommodate a wider range of voltages. Imagine what you're getting when you buy one of those P60 drop-ins from DX and KD with a voltage range from 3 to 18 volts!

It takes constant voltage to keep the light at the rated 100% output. Some regulation circuits simply "buck" and some buck and "boost." The TK11 appears to only "buck" meaning it takes the 6 or 7.2 volts from the TWO batteries and drives the light at lets say 4 volts. As the batteries wear down they're still over 4 volts so the output stays constant. Truly fully regulated buck/boost setups will use circuitry that will take more current and actually increase the voltage to keep the output constant. Those have shorter runtimes because it will hit a wall and abruptly shut off. Always a trade off somewhere!

Check out some of the other lights on that review site. It's very educational once you understand the charts. I'm to the point now where I doubt I'm going to buy lights unless they are buck/boost regulated.

The TK11 R2 has a different regulation: http://www.candlepowerforums.com/vb/showpost.php?p=2783188&postcount=15

Do you know if there are other reviews of the TK11R2? Seems that nobody else has it but they are out of stock at 47s

That's the reason why I haven't purchased one, to compliment my TK10s.
