The Better ThruNite TN31 – Super Performance, Super Quality!

The Better ThruNite TN31 – Super Performance, Super Quality!

Why is our ThruNite TN31 better than theirs?

We have a few Brand New ThruNite TN31 lights in stock.

Why are ours better?

There have been reports that some of the recently shipped TN31s and TN30s have not quite shown the attention to QC for which the company is legendary.

YOURS WILL BE PRECHECKED (unless you prefer otherwise).

$119 including shipping via Priority Mail within the US

(and add a ThruNite ti for $6 if you’d like)

Why take the chance you’ll have to send yours back?

Why take the chance you’ll have to wait for shipping from China?

We are adding another layer of QC

And that QC is being done by two highly discriminating BLF members!

Please take a look below for the (partial) checklist.

__________________________________________

About the TN31, it is by far the best quality super-thrower I know of. There may be people who don’t mind carrying around a behemoth “toilet plunger” light. There are others that forsake quality for a few more yards of throw. Then there are those people who settle for 20 seconds of turbo-mode. That’s all well and good but this is the light I would personally choose for a thrower and that’s why we brought some in for people at the BLF. There are a few good throwers in the market but most of the others can’t even come close in quality. Unlike many Chinese lights, the ThruNite TN30 and TN31 have been highly engineered – pretty much as close to perfection as flashlights can be. I could go on for pages about the benefits and attention to detail in this light but as just one example, the 7-mode and 6-level magnetic ring UI (user interface) makes it vastly more usable in a range of circumstances.

Another important point:

We’re proud to be able to say that “Our ThruNite TN31 IS Better than Theirs”

Why? - Because we do an extra full QC check on the TN30 and TN31 lights that we supply. ThruNite backs up their products as well as, or better than any of the other high-end manufacturers but there have been reports on the BLF of an occasional QC issue. The company will take care of any problems but it’s still a pain to have to pack up a new light and send it back to them. We make sure that won’t happen with the lights we’re providing. Here are just a few of things we carefully test and review.

Our Checklist for that extra layer of QC:

The bezel

The lens

The reflector

The fit and finish

LED centering

LED tint/color

The beam quality

The magnetic switch/ring assembly

The threads and o-ring

The battery carrier and potential intermittent contact issues

The master tail switch

The holster

The case

(By the way, I’ve seen some “exclusive resellers” charge $25 or more for this service.)

The ThruNite TN31 Light is supplied complete with:

Rugged Trunk-Like Carrying Case

Custom Holster

O-rings

Spare Tail Cap Cover

Lanyard

User Manual

Warranty Card (with a 12/24 month warranty!)

The Price on the TN31 is now $119 complete.

Everything above is included and the SHIPPING IS FREE within the US.

(We can also add a ThruNite ti for $6.00 if you’d like.)

Here are two Great BLF reviews on the TN31:

https://budgetlightforum.com/t/-/8528

(We all know the HKJ and turboBB to be highly experienced and detailed in their work.)

A final though about this light: There have been some “evolutionary” improvements to the ThruNite TN31 in the more recent production runs – and we have the most recently produced versions. As examples, the drivers have been “tweaked” and although the sophisticated magnetic control ring has always worked reliably, its operation has been further refined. (Unlike most, this manufacturer actually has a highly qualified engineering staff.)

Last but not least, they sold “a ton” of these lights at $190 – so at $119; a truly high-end light becomes affordable.

Feel free to get back to us if you have any questions.

Bob,

Does the TN31’s your selling have the Loctited tailcap like the others, or did they stop this on your models?

As far as throw for size goes, does anything beat the TN31?

Not in LED’s.

How does one order from you?
Russ

Well I was talking about LED for the price. The TN31 will give the Olight SR90 just about all it wants in the throw department at merely half the price and then some. A TN31 will out throw a TK70. And that is saying something in my opinion after having both lights.

would you ship it internationally (Croatia / Europe) without the case… just tn31 and a holster wraped in spunge and with lot of tape ?

And why don’t you let us know the camera settings on that picture above. I doubt very seriously that is manual exposure with a fairly fast shutter speed. I don’t know what it is with all these photos on here with no camera info. All of my pictures I list the info or you can easily go obtain it here by copying the photo address url and pasting it in the top box at this link.

Go try that with your photo and see what you get. That photo is way overexposed.

Here’s a TN31 at 445yds.

And here’s the camera info.

Sorry Bob if I sidetracked your thread, but I hate it when some silly member here wishes to throw a pitch in out of nowhere.

ILIKEFLASLIGHTS, I don’t even think it was a TN31 tested from the pic! Not even the same profile of a TN31. I’m not a camera bluff but I do know the longer the exposure time the brighter the pic.

Yea that was my point of of a pitch coming out of nowhere.

That was like a modded 9 XM-L U2 mod that was way overexposed. I can tell that by looking at it. And to set the record straight my TN31’s I would bet money will still out throw it.

Very tempted to get one, but the U3 emitters can’t be far off….

Yup, looks nice. As for the picture, the white balance was set on auto definitely, you can see the change in tints, but exposure? Looks the same to me. Check out all the windows, they’re all the same brightness.

PM sent.

Hi!

Thank you for your interest.

Ordering is very simple.

Please send a PM and we will reply with an invoice. The invoice carefully details the order and provides several payment options.

Thanks again and HAPPY NEW YEAR!

KumaBear Bob

Hi!

Thank you for the question.

One of the TN30s did indeed have Loctite on the tailcap so we didn't force it.

We haven't tested all of the TN31s yet - so I'll get back to you after we have a little bit more information.

U2 vs. U3 and some semi-scientific rambling

Hi!

There are multiple threads where the U3 is discussed in comparison to the U2 – and I found them very interesting. Also, having had some technical training regarding visual perception, color and the way we really see, I would pay particular attention to the points made by the more knowledgeable among us regarding the difference between the numbers (specs) and what the human eye can actually perceive.

It turns out that it takes a significant (percentage) increase in the number of lumens for the eye to discern a difference in brightness. Not only that, perceived brightness is highly dependent on the spectral distribution of the light and even the individual observer.

I would love to see someone address this subject in much more detail because it definitely relates to our hobby and it turns out to be a fascinating one.

I’m about to depart from the subject a little but please allow me to relate part of an experiment done by Edwin Land (founder of Polaroid and a serial inventor). I believe the experiment was done in the 60s after Land invented the polarizing filter. (My guess is that you will not believe what I’m about to describe – but I replicated a form of the experiment as part of a junior high school science project.) Please read on because it’s quite fascinating:

1) Take two slide projectors with black and white (not color) slides, both taken of the same scene.

2) Then, superimpose the images on an ordinary screen but in a dark room.

3) Take a narrowband red filter and attach it to the front of one of the projector lenses.

3) Now, look at the superimposed images on the screen.

4) The Big Question – what do you see?

5) The amazing answer – you see/perceive a scene with a full spectrum of colors!

Why???? Well, I have a T-Shirt that says “I can explain it to you but I can’t understand it for you.” To be frank, I still don’t totally understand this phenomenon but there is a great write-up of the experiment in addition to a couple others along the same lines in an old Scientific American magazine.

By the way, Land did pursue the phenomenon as a potential method for producing his first marketable instant color film.

I asked him (through his assistant) why he didn’t end up commercializing the results and part of the answer had to do with his inability to get adequate color saturation.

ADDENDUM #1) There is a little more to this than I’m describing but one key point is that the two slides were taken under different circumstances. Yes, they were both taken with black and white film but one was taken with a red filter on the lens and the other was not. Other scientists, layman and photographers would say that comes nowhere near explaining how two black and white slides and one red filter can produce a spectrum of color. Before seeing it for themselves everyone you query will predict that you will produce an image that ranges in color from red to black with various shades of pink in-between.

The traditional view of how the eye perceives light and color were challenged by the results of this and related experiments and to this day, the whole “rod and cone” explanation and all that goes along with it survives pretty much intact regardless.

ADDENDUM #2) I could go on for pages about this topic but this is neither the time nor the place for that type of dissertation.

Back to a subject relevant to the BLF and flashlights:

I have taken a keen interest in High CRI LEDs – not what Cree calls High CRI, but something well into the 90 plus percent range. In reading comments and discussing this subject with quite a few members, I’ve found that it’s a subject that most people have trouble “getting their head around.”

The difference between a CW XML and an NW XML is in the difference between the AVERAGE spectral temperatures of the light they produce – as measured in Kelvin. It turns out that neither LED, whatever Kelvin you decide is NW, will actually reflect back the full range of real life colors proportionate to the way they appear under “natural light.” In fact, the difference is huge. Let me suggest we set aside what we want to call “natural light” for the moment and concentrate on what those LEDs are doing to what we actually see when we shine one of our flashlights on a colorful scene at night.

This subject has also been covered in other threads and I don’t want to go on forever but what is clear is that there is a lot misconception and misunderstanding.

Allow me to be intentionally provocative for a moment – the purpose being to stimulate interesting debate and encourage others to “pick these points up where I leave off.”

A) The beam comparisons that we see in tests are interesting, fun, and instructive but often highly misleading – and what appears to be a significant difference in output intensity (accurately measured in lumens) is totally unimportant. Take one of the lights out to walk your dog tonight and take the other out tomorrow night. All else being equal, you won’t notice a difference even though there is a rather large difference in lumens.

B) The binning and labeling process that Cree uses leave a lot to chance. An LED that is rated as having a higher output may indeed have a lower output as measured by accurate instruments – that’s partly because the process is simply not that accurate (something that Cree admits in their specs – and it may be even less accurate than they say- or than sellers would have you believe). Add that fact to the logarithmic nature of the eye’s sensitivity to light and these numbers that we throw around with so much import, should be taken far more lightly (pardon the pun).

C) IMHO, almost all of us (and I include myself here), make buying decisions based on the wrong criteria!

D) COLOR ACCURACY gets short shrift: Personally, I think it would be great if we could see comparison shots of an array of color construction paper or a colorful real-life scene. I’m not sure how this would be accomplished but if we’re comparing two flashlights, rather than having two photos, how about three – one being taken in “natural light” so that we know what those colors should actually look like.

Granted, its fun to see how far away something can be while still being able to light it up. To cite another example, if you’re riding your bike at night, it’s certainly not as important to see the “natural color” of that pothole in the road as it is to see it in time to avoid it in time.

Needless to say, there are many examples like the above but I would say that color accuracy has gotten “short shrift” in our discussions and tests – just an opinion (and debate is welcome).

E) “Pencil Beam” vs. “Peripheral Vision”: I often finding myself trying to find something in a dark area. A flooder, a zoomer or even a light with a really good usable spill are essential to my practical use of a light. There are those that use their lights strapped to a hunting rifle or some other specialized purpose but how many of us pick up a light simply to impress our friends with how far off it will shine? Please don’t think I frown on this practice. It’s fun! – And I do it myself. On the other hand, if a light is going to get good use and not be relegated to “shelf-queen” status, how should it function? Again – opinions and debate welcome.

F) Quality, Durability and User Interface: I throw these topics in together solely for lack of time and space. Collectively, these areas are almost always attended to by our fantastic reviewers. I just wish all the manufacturers did the same. I could never be part of the “money is no object crowd” but I do find myself paying more and more attention to these things and my sense is a lot of us our doing ourselves a disservice by ignoring them – more on these topics later

Epilogue: Sorry to bore you with a lot of rambling – just had some time to burn and felt “semi-philosophical” for moment. Take it for what it’s worth.

Regards and HAPPY NEW YEAR!

Shipping to Croatia/Europe without the little trunk-like case.

Sure!

The case adds a large amount to the international shipping cost.

Your idea makes a tremendous amount of sense to me. The case is nice but it’s bulky, has only one limited purpose and is best used as a presentation vehicle for a present.

I suppose those with a lot of room or that have a particular reason to protect the flashlight might have an ongoing use for it but there is a price to pay.

Please send me a PM with an address and telephone number so that I can get quotes from several carriers.

Hi KumaBear,

I am trying to decide between a ThurNite TN30 or TN31 - I am reading reviews on both. Since I recently ordered the SKYRAY XY-600 6 x Cree XM-L T6 from DX, I’ll likely start with the TN31. I am new to lights and learning. Sadly with the SkyRay I fell victim to the “more emitters must be better” excitement.

But I am ready to buy Batteries today - (However, if it makes sense to combine shipping for a TN31 and Batteries I’ll likely just pull the trigger on a TN31).

I would like a quote for Eight ( 18650 Protected KEEPPOWER BRAND Batteries using the Panasonic NCR18650B 3400.) If I buy a TN31 I’d up this Battery order to 11 18650’s.

As per your “read me” these should fit in the USPS SMALL FLAT RATE PRIORITY MAIL BOX.

If you can fit Four (4) additional 14500 Protected KEEPPOWER BRAND Batteries DLG 14500 800 batteries in this box I would like to order these as well. If not, let’s just stick with the Eight 18650’s. (or 11 if I go with a TN31).

Please check the PM I sent you for shipping address and other questions.

Thank you,

Dante

PS – My Charger is an XTAR WP2 II

Bob, I think you should start a new thread for that so more people will see it. Very interesting though.

This is why I love this forum and the people on here. Your pricing (I've got a good clean running TN31 from thrunite's sale) makes me both sad and happy. Sad that I could have waited and saved $20 and bought your TN31. But that is how things are these days anyhow and mine worked flawless so not really complaining. Happy because you make BudgetLightForum what it is by making it possible for a lot of us to afford a highly robust and well designed throw monster that usually cost somewhere north of 2 benjamin's. I do appreciate your trailblazing. Thanks.
