Original TK-75 VS. New TK-75

[CyberCT]

I'd be surprised if the XML2 version runs at the exact same temp as the XML version. I have a hunch the XML2 TK75 will run a bit cooler to the touch. Not "cool" but "cooler". Like I said the XML TK75 is not practicle for running constantly on turbo because it gets VERY hot. If the MXL2 TK75 runs just a little cooler where it gets very warm running constantly on turbo, that is a huge reason to upgrade in my book.

Thats why I need someone with a newer TK75 to verify. Run the light on turbo for 20 minutes. How hot does it get?

Can someone with the XML2 version please verify my request above?

I´d like to know that to! I m planning to buy an old version of the TK75 when i found it to a sales price, but since Fenix has not answered how they deal with the fog behind the lens issue, i might pass the old version. I´d like to hear feedback from owners of the TK75-L2 about how hot does it get when running it for turbo for 20 minutes,and does it also has condence behind the lens?

Just a general comment/post here gentlemen[maybe a few gals!]

I just saw my neighbor Frank. I told him I just got another flashlight a few days ago[EA4] and am expecting another[TK-35] tomorrow!!

He shook his head and said, "Looks like you have a flashlight hall of fame up there"!!!

HE DOES NOT UNDERSTAND, THAT IS OK,,,HE IS ABNORMAL,,,,,,,,US FLASHAHOLICS ARE THE normal ones!!!:sssh::rock::hahaha:

Ciao,,,Roberto,,,"Capo di Capo" "KEEP LIGHTING UP THE DARKNESS"

P.S. IT IS THAT TIME!! IT'S GETTING DARK,,,TK-75 IN RIGHT HAND, SIBERIAN IN LEFT AND THE EA4 ON MY HIP!!!

Hi,

I hope I can be of assistance here (with my first proper post after my welcome)

I just bought the new TK75 from fenix-store.com. I'm from UK and its not for sale yet anywhere I would find. It looks like I got the last one as its now showing out of stock

When it does arrive (2 or 3 weeks I imagine) I will post my thoughts on it and do some testing RE fogging and heat after 20 minutes on turbo

I also bought the following items to go with it -

Nitecore Intellicharge i4 V2 charger

Based the thread here http://www.candlepowerforums.com/vb/showthread.php?348959-Batteries-for-Fenix-TK-75 some Fenix batteries

Fenix ARB-L2 2600 mAh 18650 Battery (x4)

Prices were as follows;

TK75L2 - £119.61
Charger - £21.45
Batteries - £46.68

Total £187.74

Don't think I did too bad considering the 'old' TK75 is £160 in UK

Anyone know how warm/cool (in K) the light color is on the original vs the new one? Or the CRI rating? Can't find any specs on this.

Original TK75 is 6500k - cool white

I dont understand how the two compare. Isn't one a modified TK75 and one a normal one? (not the TK75L2)

As far as I know both the TK75 X-ML and X-ML2 are both cool white 6500k.

Beam shot was only intended for reference - to show how blue/cool white either TK75 would be.

Thanks. I ordered from fenix-store on 14th September and the new TK75L2 is shipping on 26th Sept (due to Chinese holidays and stock issues)

I only had the New version for a few days because I thought I would notice a difference in output, which I did not so I sent it back. I only actually used it for about a half hour[on turbo].

In addition to not noticing[ the human eye!] an output difference between the two, I also did not notice the New version getting any hotter. again, it may not help you, this was only after one use. It was the middle of August and it does get hot in Pa.!

As far as the original one, which I still have, I have to DISAGREE with you in regards to it "not being practical for running constantly on turbo".:)

That is all I use it for!! Constant turbo for 60 min.+, winter or summer. The handle can get warm, a little hot but certainly not uncomfortable where I can not hold it!

I hope someone else who has the 2900 Lumen TK-75, for the last couple of months can help you more with the heat concern. Personally, I do not think it would be an issue. My issue[another thread] was the Condensation under the lens which I resolved by using the "Silica gel" treatment! No issues whatsoever anymore!:thumbsup:

I agree that you won't notice a difference in output vs the XML version. However I find it surprising you could just run turbo for minutes on end like that. Last winter I had turbo running for maybe 20 minutes and had the head of the light upside down on tarp. Well the flashlight burned a hole through the tarp!! It was 3 small holes so the head coming out of the XMLs actually was hot enough to do that! The head is also quite hot to the touch. My main reason of running this light on constant turbo was to go snorkelling in freshwater, which I have unfortunately not had the chance to do yet becuase I had to move out of state for work.

Next summer though, I will be home to finally test it for the purpose I bought it :)

Tailstanding with no cooling is already a tough test. But you managed to come up with a tougher test. Not only did you have no airflow, and no conductive cooling from holding it, but you also even further restricted the airflow around the head, as well as wrapping part of the head with an insulator. Given that, it doesn't seem surprising that it got hotter than it ever would with "normal" use. Rest assured, if you are holding and swinging it through the air as you walk, you won't have any issue with overheating.

I also cannot figure out why you still insist on thinking the XM-L2 version will run substantially cooler. Yes, it is about 10% more efficient, but you are getting 10% more lumens out of it. I'm sure with a rigorous scientific test you could detect some difference, but in normal use, it is six of one and half a dozen of the other. The variation between XM-L lights is probably as great or greater than the difference between XM-L and XM-L2. And if you are planning to use it underwater, what difference does it make anyway? Water cooling is pretty darn effective...

It also gets very hot held by hand, that doesn't change. I also thought the XML2 was 20% more efficient.
Underwater use isn't my only reason for having it. If I want to go fishing at night for a few hours and leave it on the turbo mode, even just a little cooler would be a plus.

Test results on a Dutch site:

"Old" TK75 2 lux at 210 meter
TK 70 2 lux at 215 meter
"New" TK75 2 lux at 237 meter
RC40 2 lux at 237 meter

So, the new version throws out :) my good old TK70 and throw is almost the same as the RC40....

Can anyone with a tk75 xml2 look at their battery carrier and confirm that it has 'fenix' written on it. My sample does not say fenix on it. [i noticed in pictures it clearly has it written on the end] thanks in advance.

I confirmed that it DOES say Fenix on the BOTTOM[FLAT PART] of the battery carrier. For both my original and the Extra battery kit/carrier that I got.

Where did you get yours? Do you think it is a "Clone/Fake??

Ciao,,Roberto

 

[swan]

Thanks Roberto for the reply, thats interesting that both your carriers have fenix on the bottom. I dont think its a fake as i bought it from a local reputable dealer , it seems identical except for the missing logo. I really like the light- just curious?

Your welcome

If I had to guess I would say that it is a clone.

It is kind of strange that it does not have the logo! As long as it works ok that is all that matters!

Yes, it is a great light!! I use it to walk my Siberian!!!!

We don't walk through neighborhoods! I go to isolated country roads or hiking trails where all we see is wildlife!

Mate,,, Is it a little after 11 am where you are on Tuesday??!

You could contact Fenix. They should be able to tell you if it's authentic.
