Hi Selfbuilt, I've got a question.

Looking at Klaus' website they list the the XT30 at:

The Beam Distance and lux in your review (48.800/442m) is quite significantly different. Can you help me understand why and what it means? And if ANSI FL1 figures produce 'higher' numbers, why aren't Klarus using them on their website?

Thanks.

Hi selfbuilt I was just wondering why in some of your reviews it shows the t40cs at 46000 lux and this one shows 54000 lux?

thank you just wondering which one is correct

I don't know why, but they clearly seem to have the peak intensity numbers off on this model (at least, based on my one sample). :shrug: Given the output level and the size of the reflector, I am not at all surprised by the lux numbers I directly measured here.

The new numbers are more accurate, as they are taken with a NIST-certified light meter. The link is provided in the methodology paragraph before the table, but here it is again: Revised Selfbuilt beam intensity explanation.

You can tell the new tables as I have put the numbers with the new meter in orange. And yes, I went back and re-tested every light shown in all my tables.

thank you for the clarification

Hey Selfbuilt, Thank you very much for this great review :thumbsup:
but when are you going to upload the outdoor beamshots? because I am want to buy for me the Klarus XT30 or the Sunwayman T40CS,and I can not decide which flashlight is better thrower.
thanks advance.

In his chart at least, the SWM looks like its got slightly more throw than the XT30.

In real life, the variation from light to light typically overlaps the small differences in specs...so on paper two lights might be different, but an INDIVIDUAL light from a given batch for that model might be a bit brighter or dimer, etc...so the brighter one of the dimmer specs, and the dimmer one from the brighter specs, can overlap in real life. (IE: Assume that the specs, beamshots, etc...give a ball park idea, but are not going to guarantee that the one YOU get is exactly like that in performance. YOUR XT30 might out throw someone else's SWM, and visa versa)

:D

Still on my desk to do, just been too busy lately to head out for the outdoor shots. Hope to get to them soon ... but see my comments below.

This is a key point that people often overlook when dealing with n=1 sample sent for review. There is a natural range of variation, and it is impossible to know what that is without a good number of samples to compare under idendical conditions. It is impossible to know the averages for a given model - and even if we did, it is possible that any one sample of one model could out-perform another (even if the averages were the other way).

That said, the T40CS has a rather different reflector and beam profile from the XT30. The T40CS has a wider and relatively shallow reflector (with flat base), while the XT30 has a deep reflector (what comes to sharp angle at the base). The effect on beam profile is that the T40CS will always have a much wider (and dimmer) spillbeam than the XT30. As for the hotspot, at least on my two samples, the XT30 has a smaller and more sharply defined hotspot, with the T40CS having a broader one with a more gradual transition into corona.

Finally, as an aside, I know everyone is always keen to see outdoor beam shots. But the reality is that it is hard to compare lights from a single camera exposure (or even a range of exposures, for that matter). A camera will never catch what your complex brain interprets and perceives. Personally, I find they are (at best) really only useful for comparing gross beam pattern differences - not subtle intensity differences in peak throw.

I see you have been talking about getting a thrower for a while now in just about every thread, Like said many times before all the ones you are interested in have close throw ability but from my experience the new u2 t40cs throws slightly better then most in its category including the xt30

It looks like a great light, but I'm not a fan of the plunger design. Anyway, I (and I think most of us here) buy new lights for dazzle, show and novelty, and not necessarily for practical use. I find my X10 Maelstrom and S10 Baton to be perfect for my daily needs and my other lights are, for the most part, for showing off. I love the beam of my TN31 and doubt I'll be getting another long thrower until something comes out in a compact package and an affordable price range that SIGNIFICANTLY outperforms it. I'm sure the next breakthrough in LED technology is just around the corner.

Very nice review. I am considering this light as a new patrol light. I have a couple smaller belt lights, but want a new large light to replace the old Mag I have used for years. How would say the durability is? Thanks!

It certainly seems like a solid light, in keeping with the other Klarus models. Long-term reliability is of course always an unknown, but the positive experience most seem to have had with the XT10/XT11 should bode well.

Oh, and :welcome:

i wonder how this'll compare to the new Armytek Barracuda. any speculation, selfbuilt?
Don't know the specs for that light, but it typically comes down to the size and shape of the reflector in this class. This 2x18650 thrower space is fairly mature, and most makers produce lights of comparable drive levels. As a result, it comes down to optics (in terms of throw), as well as the usual build, circuit and UI differences.

okay, thanks! i hope someone sends you one for review then. i'm sure it's as good as the Predator but in a thrower formfactor

I finally made it out for some outdoor beamshots. Please ignore the red-tint in the lower-right corner these shots (I was wearing a brighter-than-usual red headlamp during this excursion :p).

Here are zoomed in shots of the hotspots:

The XT30 is certainly in the same range as these other "thrower" lights. :wave:

No, only the tailcap threads are the same between the XT11 and XT30 - the head-region threads and diameter are quite different. If you look at pics in the two reviews, you will see they don't look the same. I can confirm they are not in fact interchangeable.

I don't know the specifics for the circuits, but my guess is that they are indeed customized for the supported voltage range of the given models. It would be inefficient to add broader voltage support for configurations not physically supported by the light.


I know the tail caps of the XT11 and XT20 are interchangeable, but not the heads. The head threads are larger on the XT20.

I'm thinking the XT30 is more like the thrower version of the XT20 than the thrower version of the XT11....and would not be surprised if the XT30 head would fit the XT20 tube, etc.

:D

The XT20 tube is HELLA thick, very sturdy. That would make the XT30 a flaming baton. :D
