Thrunite Neutron 2A (1xAA/14500 2xAA) and 2C (1xRCR/18650 2xCR123A/RCR) 2014 Review

[realista]

thank you very much for your reply..... i learn new things reading you.

2XAA = 700+ lumens

is this even possible ?

i bought a olight ST25 not long ago , and it was claimed the best 2XAA ......at 550lumens ( more like 450 lumens )

omg...i think i need to get this now.........

Yes, I think we were all quite surprised to see that. I certainly didn't expect it.

Yes, the ST25 is somewhat over-stated at 550 lumens (but only because of the rapid drop off). See my new review of that model.

kind of surprising that the neutron 2c has the same runtime on high with 18350 imr and 18650 aw, i would have thought there would have been significant increase when going from 3.7v and 700mah? to 3.7v and 2200mah. i would think at least some increase but it looks like from your charts they are the same. am i seeing this right?

 

[michael3]

i was looking to see which of the other lights on your chart were comparable to the neutron and i noticed that for max output on the eagletac d25c you have it at 770 lumens but the website for eagletac list it at 317 lumens. i was just wondering how there was such a significant difference in the output? thanks

No, the runtime graphs show that the 2C lasted for 28 mins to 50% on AW 18350 IMR, and 1hr 23 mins to 50% on AW 18650 2200mAh. So that's effectively 3x longer (as you would expect for 2200mAh vs 700mAh rated specs).

That's because the original release of the D25C didn't fully support Li-ions - the light entered into direct-drive, at a maximal drive level. Subsequent editions of the D25C (after the review) have a different circuit, that limit max output but restored regulated performance at multiple levels.

i was speaking of high not max and both show a clear step down at close to 90 min.

No, I never tested 18350 IMR on Hi specifically - the only data I ever showed was for Turbo on 1x18350.

I haven't plotted it, but I have tested 2x18350 on Turbo, and got 59 mins to 50% (compared to the 41 mins on 2xRCR). I didn't bother plotting this though, since I don't have any other 2x18350 data to compare.

As an aside, I realize that one thing that might be confusing is the legend on the 1x form graph where I show Turbo for 1x18350 (specified), but my regular 1xRCR is used for Hi (unspecified). Unless otherwise specified, all the 1x form runtimes are based on RCR.

EDIT: in further discussion, I realized the issue michael3 was referring to - the Med mode run on 1xRCR was incorrectly labelled "Hi" on the Med-Hi 1xRCR runtime graph. The legend label has been changed to Med.

Neutrons 2A (2014) arrived already. Thrunite told us 2C types will come a bit later.

Just ordered this light (via, Amazon), and 6 Efest IMR 14500-700Mah battery's. This will be my forth Thrunite Flashlight.
I have the TN12-2014, Lynx and Archer 1C (GF's purse light) in hand. I use both of mine every day, multiple times. Very happy with them.

The only other AA lights that I currently have is Nitecore MH-2A (550lm, With it's proprietary 2x14500 li-ion) and Klarus XT1A (180? Lm) and of corse many Maglight 2xAA's.

I've been in the market for a single AA light, that is side button activated, performs well with 14500's, krazy bright with well thought out med. and lows. I think I found it, we will see.
Was thinking about the Xtar 'WK-41' and Armytec 'Partner'. Zebralights crazy/overly complicated UI, Olight was sorta okay, but no, not for me. All this looking around put me in a holding pattern, until I saw this review('humm, I allready use two other Thrunite's, might as well try this one, the price is right' I say to myself).

Great job selfbuilt!

Next up the TN32 or Catapult V5. Decisions, decisions.

Just a quick and dirty cellphone pix for some of the tint and sub-lumen snobs out there.

L > R: '14 D25A N219, '12 D25A NW XML1, Neutron 2A NW, QPA-XML1 NW, QPA-XML2 CW, SC52-XML1 CW

Top (tint): D25As on 7 lms, Neutron on 11 lms, Quarks and SC52 on 3 lms

Middle/Bottom (sub-lumen): D25As on an L91/Eneloop (full 0.5 lms output requires ~1.5V+), Quarks and SC52 on 0.3 lms

 

[selfbuilt]

Thanks for the comparison reppans. I only have the SC52 to directly compare to yours above, but the relative relationship of my SC52's "0.34 lumen" mode on 1xNiMH is similarly a little brighter than my Neutron 2A's moonlight (1xNiMH). On my estimate scale, I rate that level of the SC52 as ~0.09 estimated lumens, compared to ~0.05 estimated lumens for the Neutron. Of course, the SC52 has two even lower levels.

i've recieved my neutron 2A today. apparently the holster can only fit the light without the extension tube. :thumbsdow

Well they would then have to include two holsters for each configuration.
It's a pretty inexpensive light.

Received neutral one today from amazon - can't access turbo on eneloop , usually it starts 'random strobe' flickering , tint is greenish , works normal on 14500 most of the time , but not all the time - going to collect sc62w and sc62c in a moment - hope one rotten apple a day is enough .

 

[Anders]

Got it yesterday.
The first impression is that it must be some kind of light to see what you are doing when turn it on and off, it is very hard to feel the tiny button ...
This is not good at all.

 

[markr6]

Ouch two strikes! Too bad, I was really interested in this one.

going to collect sc62w and sc62c in a moment

I'm interested to see what you think about these. Please post your feedback if you get a chance - proabbly in the SC62 First Impressions thread

You should have the Quark AA2-X (QP2A-X) - that light regulates the same moonlight output on any batt. combination, but you could always run a dummy cell in the 2AA tube if you don't have a 1AA tube. I'm surprised you rate this Quark's moonlight at 0.13 lms - I have quite a few samples which are stone consistent.

Try cleaning the tube edge/brass contact ring in the head and tightening down the batt tube more. I notice the same behavior and found this light needed to be tightened down more than I normally would.

Reppans - thank you for advice , seems it works properly now
markr6 - wait till it gets dark in uk

 

[mekquake]

damn it - it still needs gymnastics to get to turbo mode on eneloop
