Review : ThruNite Neutron 2C flashlight (xp-l v6 , usb charging , ramping)

A few words for ThruNite Neutron 2C :

The Neutron 2C V3 micro-USB chargeable flashlight adopts a latest CREE XP-L V6 LED to make output up to 1100 lumens with the combination of an interesting ramping UI .

Overview/Specifications :

  • LED: XP-L V6 with a lifespan of 20+ years of run time.

  • Working Voltage: 2.7 – 9.0 V.
  • Output mode/Runtime:
    Strobe(650 lumens /5 hrs)
    Turbo(1100 lumens /2.2 hrs)
    Infinity High(650 lumens /2.7 hrs)
    Infinity Low(12 lumens /130 hrs)
    Firefly(0.5 lumens /49 days).
  • Peak Beam Intensity: 14399cd (max).
  • Max beam distance: 240m (max).
  • Impact resistant: 1 meter.
  • Waterproof to IPX-8 Standard (2meters).
  • Weight: 86g without battery.

  • Accessories: Holster x1, Spare O-rings x2, Lanyard x1, Pocket Clip x1, 18650 3400mAh Battery x1, USB Charging Cord x1

First Look :

Flashlight in it’s box , the classic brown Thrunite box , which i have to admit that i really like :

Package Contains :

  • Flashlight
  • Holster
  • User manual
  • “Thank you” card
  • Lanyard
  • 2x O-rings
  • Pocket Clip
  • E-switch rubber “sealing”
  • 2x extra charging port rubber sealings
  • Thrunite 18650 3400mAh battery (inside the light)

A closer look :

Here we have latest Thrunite flashlight , the Neutron 2C . Another all-in-one solution , like the tc12 v2 but i would dare to say with a better UI (that we will discuss later) :

What’s special about this light ? A battery tube that accepts a lot of different battery combinations with the use of a removable extension tube :

Light with the small tube Wink :

And now length is only ~94mm :

Let’s get in the details now !

Flashlight’s head has a nice minimal design , with the metal e-switch and the charging port on the back side .
Through the e-switch you control the flashlight . Notice also the little led in the center of the switch , which works as a battery/charging indicator :

Back side , with the USB charging port :

Flashlight has a SMO reflector and AR coated lens :

Reflector is deep ! In the center you can see the nice cree xp-l :

The pocket clip which is also removable :

Tube has kind of aggressive knurling , but i think it adds a lot of grip :

The end of the tube is flat , and has a small hole on the side that accepts a lanyard :

Nice , “square” & anodized threads :

Here is a photo of the positive terminal that the battery makes contact :

Flashlight’s Holster :

Holster is designed for Neutron 2C , it’s a pefect fit! :

Battery :

This is the battery that comes with the light :

It is button top , protected , but it has a high discharge rate :

Actual capacity tested : 3430 mAh

How it works (&modes) :

Turn ON/OFF :
Single click the switch to turn the light on and off.

Shortcuts from OFF :
Long press the switch to get firefly mode.
Double click the switch to get turbo mode.

To Change Modes:
When the light is on , long press the side switch to increase or decrease flashlight’s brightness , wherever you want , in the 12-640 lumens range. If the light blinks , it means you’re in the min or max setting , and it will start to ramp in the opposite direction if you don’t stop pressing the e-switch .
Double click from any mode to turbo, another double click to get strobe.

Memory Function :
The light will turn on in the last mode accessed, except firefly, turbo and strobe.

Ramping mode video or gif :

Coming soon…

Battery Indicator :

When you’re in ramping or turbo , the little led in the center of the e-switch works as a battery indicator .

Voltage Above 3.2V 3-3.2V 2.8-3V Below 2.8V
Indicator Color Blue Flashing Red Red Flashlight turns off

Usb Charging / Indicator meaning etc :

When the flashlight is being charged , RED led is on , but after being fully charged, BLUE Led will be on. It takes around 4 hours to fully charge the 3400mAh battery.

Voltage 2.7-4.19V (Charging) 4.2V (Full) Error (Ex No battery inside OR damaged battery
Indicator Color Red Blue Purple

Charging Current : 1.00 A (pic here )
Termination Voltage : 4.19 – 4.20 V

Measurements :

Thrunite 3400mAh battery was used in all measurements

Lumens :

  • Firefly – < 1 lumen
  • Ramping min – 12 lumens
  • Ramping max – 640 lumens
  • Turbo – 1072 lumens

Note : Tested flashlight’s performance with an Enercig IMR 18350 and found out that the light performs as good as with the 18650 (but with lower runtimes of course) .

Intensity : 12,7kcd

My runtime tests :

Turbo mode :

Ramping max :

Over 90% of the total output (about 580 otf lumens) for about 110 minutes .

Beamshots :

Wall @ 12m :

Control shot :

Turbo :

Ramping max :

Ramping min (a little over exposed to be seen) :

My flashlight is the cool white version but tint isn’t green , but a tiny bit rosy .

Conclusion :

Here are my thoughts about this flashlight… It is a great light , made with high quality components and a really good anodization (and it has been proven from older beaten up Thrunite lights) . It is a good all-in-one solution if i could describe it in a few words . The flexible ramping UI is very useful , letting the user select the desired brightness without the limit of the 3 or 5 modes , and great shortcuts in moon / last used mode / turbo . It accepts a lot of different batteries combination , which i find really handy … With a bit over 1000 lumens on it’s max setting , a nice tint (my CW tint is rosy without a hint of green) , a nice battery indicator and a fast usb charger inside the light i believe it is a great choice if you look a flashlight that can fulfill most of your needs .

More info can be found in my detailed review Smile

Cool little light. A nice e-switch alternative to the S2, with its 18350 compatibility. The UI is good, the same as the thrunite TH20 headlamp I think. Although the ramping seems slow compared to my lights with Toykeeper’s ramping FW flashed.

Personally i like the “slow” ramping , for easier control (finding the suitable brighness) .

Can you reverse the ramping by releasing the switch and holding it again?

Hey that sounds like an iteration of Narsil.

I am a big fan of ramping Big Smile , so i was excited since the announcement of this light .

What i really like and i think it will be useful for the average user is they big variety of batteries that it accepts , from 1*18650 / 1*18350 to 2*16340 / 2*18350 etc .

In your beam images you light up a plant pot. What kind of plant is it and is it native to Greece? Great review.

Excellent! I plan on using mine with an 18350. I have a few Efest 900mAh’s in stock. I really like that it’s flexible with battery sizes.

Thanks ! Haha i can’t really remember it’s name , but i will reply here when i do Silly

.

Also , updated in the first post the output/time diagram , on the highest brightness of the ramping mode . Over 90% of the total output (about 580 otf lumens) for about 110 minutes …

With the provided 3400mAh battery , it rattles but only a little . Maybe with unprotected and/or slimmer batteries there is a biggest issue .

The rattling is easy to fix. Just wrap a post-it note around the battery. No more rattle.

Does the switch stay lit in all cases?
I prefer the battery indication to signal on activation then turn off, for all battery states; signal intermittently (say every 10 seconds) during use only when the battery is below 25%; every 5 seconds when the battery is below 20%; then not signal during use but step down the output when the battery is below 15% to prolong remaining runtime.

Great price but I still don’t want to risk getting a green NW.

Yes it stays on all the time , in every mode except firefly mode .

TC12 V2 nw had a great tint , this light is CW and tint is pure white , and maybe a little rosy on the edges .

Really happy with the light so far …

Mine arrived today. So far I’m really liking it. It runs fairly hot in the turbo mode, but not hot enough to be of any concern. I haven’t measured battery life yet on the Efest 900mAh 18350 I’m using, but it does seem to do pretty good. The tint is supposed to be cool white, to my eyes it’s closer to a neutral white

Do you think it’s a little rosy too ?

It’s probably a CW tint i could live with …

I wouldn’t say rosy, but then again I’ll have to look at it again tonight on a white wall. It’s definitely not cool white. That’s for sure.

I believe not a single Thrunite has electronic lockout, which I pity.

Sure it works. I just find electronic lockout… well sexy. Especially if you get like a feedback from the illuminated switch with a couple of blinks.
