ThruNite Neutron 2A v2 (1xAA/14500/2xAA)XM-L2 REVIEW

ThruNite have updated their Neutron models.
The flashlights are now compatible with different size batteries and come with an extension tube for doubling the power source.

The New Neutron 2A v2 pretend to be the brightest flashlights in AA size powered by 1NiMH and 14500 as well.
460 lumens from a single NiMH battery is really impressive achievement.
The 2Av2 can be used in 1xAA or 2xAA configuration.
Working Voltage: 0.9-5V



Black finish. Hard anodized aluminum body.

The switch is electronic push button,placed low in the body compared to some other flashlights with a side switch.
It doesn't protrude too much and in my opinion is relatively hard to press it accidentally.
Of course any electronic side switch could be pressed accidentally by hard object or under too much accidental pressure.
If you afraid of accidental activation,you can lock out the head.
The UI has no locking option.
As many other side switches,finding the switch in the dark requires some time.
The switch has no easy to find by touch shape and could be too small for big fingers.
There is no click sound.


Excellent knurling. Just the right depth-not too light and slippery,not too aggressive to scratch everything around it.

The tail is flat,allowing good tail-stand option.
The pocket clip is removable.Quite stably attached for this type clips.



Standard for ThruNite packaging.
Very nice cardboard box.
Accessories-Pocket clip,Very good Holster,Extending battery tube,Spare O-rings.


Dimensions:
- Length: 96mm 1xAA, 146.5mm 2xAA
- Diameter: 25.4 mm(head)
- Weight:
59gr. 1AA size, 86gr. with a NiMH battery
76gr. 2AA size, 129gr. with NiMH batteries

The 2C v2 has a good anti-roll design.


Size comparison.
Sunwayman S10R,Klarus RS16,JetBeam RRT0,Neutron 2Cv2,Neutron 2Av2, Keeppower 3400


JetBeam RRT0 with extender, ThruNite TN12, Olight ST25,ThruNite 2Av2, AA NiMH battery




Well machined parts.

Physical reverse polarity protection to protect from improper battery installation.
Aluminum body with quite thick walls. All parts fit well,without gaps.







Triangular cut threads with rounded tops.
Anodized.
Well greased O-rings.

CREE XM-L2 U2 LED
Perfectly centered LED on my sample. Aluminum smooth reflector.
Toughened ultra-clear glass lens with anti0reflective coating.





Identical smooth reflector with the TN12(2014) and Neutron 2Cv2.All lights with a Cree XM-L2 LED.
ThruNite TN12(2014)- ThruNite 2Cv2- ThruNite 2Av2- Skilhunt DS10



Quite good grip.





User Interface.
The Neutron 2A v2 shares the same UI with its brother Neutron 2C v2.
Same side switch,same mode sequence and operating.My opinion of the UI is the same for both models.

5 brightness modes.
3 main modes High-Mid-Low repeating in sequence High-Mid-Low-Mid-High-Mid...
Switching ON/OFF by short click.
Press and hold the switch to cycle between all modes.
Very smooth transition between all different modes. Very pleasant to the eyes,without sharp changes with stepping from High to Low or Low to High,which is hard for the eye adapting. Mode changing reminds me on a flashlight with magnetic ring with infinite brightness control,not only because of the mode sequence,but also because of the smooth transition mode to mode.

There are two hidden modes-Turbo and Moonlight.
Turbo is accessible by double click from Off.
Press and hold the switch from Off to activate Moomlight mode.

There is an instant memory for the main modes High-Mid-Low.
Turbo and Moonlight are not being memorized.

There's no Strobe or SOS.

The light is current regulated on all modes with no any sign of pwm.
Definitely one of the best User interfaces I have tested.
Easy and quick to use. Instant memory and good choice of modes are welcome for any EDC light.

Short demonstration of the 2A v2- Design and UI.

No voice(I am not good in speaking),turn on captions.



Max lumen output according to manufacturer:
1xAA NiMH
- Output mode/Runtime:
- Turbo : 480 lumens /80 minutes
- High: 230 lumens / 90 minutes
- Mid: 70 lumens / 3 hrs
- Low: 11 lumens / 72 hrs
- Moonlight:0.04 lumens/33 days
2xAA NiMH
- output mode/Runtime:
- High: 230 lumens / 215 minutes
- Mid: 70 lumens / 7 hrs
- Low: 11 lumens / 7 days
- Moonlight:0.04 lumens/68 days
- Peak Beam Intensity: 8540cd
- Max beam distance: 185m

The ThruNite 2A v2 is impressively bright on Turbo mode for a AA light.

My approximate lumen measurements:
1xAA NiMH
Turbo 460 Lm
High 221 Lm
Mid 67 Lm
Low 9.8 Lm

2xAA
Turbo 750 Lm

1x14500
Low 7.66 Lm
Mid 65.7 Lm
High 221 Lm
Turbo 850 Lm

The Neutron 2A features a Low voltage warning combined with a low voltage protection.
The low voltage protection performed excellent in all tests protecting the batteries from over-discharging.
The warning(flashing) function doesn't work so consistently and sometimes fails to work.
For example in the 2xAA runtime curves is not visible any flashing,but when I insert nearly empty batteries the low voltage warning is activating after a few moments.

Due to the electronic switch,the 2Av2 draws a low Standby current 60 µA.
Threads are anodized=lock-out is possible.

This is a runtime graph.
Displays the Lumen output for the time in minutes.
I did not test the runtime on Turbo mode with a 1x14500.
Due to the high current in this Mode is recommended using a IMR/high current draw compatible battery.

There is a brightness step down 4 minutes after activation to protect the flashlight from overheating.
The Neutron 2A performs impressively well,maintaining constant brightness after the step down with decreasing the output in the last minutes on 1xAA NiMH battery.

(click on picture to see it larger)


Beam of the Neutron 2A is almost the same as the Neutron 2Cv2 and ThruNite TN12's beam.
Both flashlights use Cree XM-L2 LED and visually the same reflector.

The LED on my sample gives a cool white light with no greenish or bluish tint.

As expected from a smooth reflector,produced beam is not clean of artifacts and transition from hotspot to spill is not so smooth.

Thanks. Be interesting to know the current readings at all levels for the single AA battery configurations, NiMH and 14500. Also the factory listed single AA Turbo run time claim seems ridiculous seeing as how all but the first few minutes are after the light has stepped down to the High output level which is less than half of the Turbo maximum output. To me Turbo battery life time should be listed only if the true Turbo output can be sustained. As is it gives a false picture.

Thank you for the review Smile

Anyone knows who has the best price on the neutron 2C V2 and the 2A V2?

Thanks!

So it can still hold 1 hour on High at about 200 lumens, not bad  I think..

Can the 2C V2 work with 1 NiMH using the extension tube and a spacer?

Good Day FlashLion, Smile

 

Great review....

 

You said re Turbo Mode: "Due to the high current in this Mode is recommended using a IMR/high current draw compatible battery."

Could You Please give us Turbo Mode's current draw (Amps) when using single (one) AA & 14500 batteries?

 

Thank You Very Much,

George

Thank you all for the comments!

Actually,the first thing I tried to measure when received this flashlight was the current on Turbo mode with a NiMH battery.
But,it’s somehow hard to hold the battery and the DMM leads and to press quickly twice the switch to activate Turbo.
I will try again later today.

Good luck with that, I know, I can dream though.

Light really looks well thought out.
Thanks for yet another great review.

Thank you for the review. That is impressive output even if it is "only" for 4 minutes at a time. Well done!

And really nice review. You do excellent pictures and technical descriptions and I like your down to earth comments about how it handles and works in daily life too. TY Big Smile

Just got it from HKequipment. High quality box. The light has good build – not as polished as Zebralight but quite good. The switch is a bit small but provides good tactile feeling. The output is amazing. The size is significantly bigger than Zebralight – must be to handle the heat from such a monster output.

***AVOID THIS COMPANY!***

I bought a Neutron with my credit card and they never sent it to me. I tried emailing them and they said it was shipped, but it never arrived. Now it’s too late to dispute it and they are ignoring me. Can anyone help?

Nice first post sparkles. Your post can be taken more than one way. Undecided

If your not happy with the company why trash this thread when you could start your own and put more detail in it?

A lot of companies have a disclaimer stating that their responsibility ends once the item has shipped unless you pay extra for insurance, if even offered. Even if insurance is not offered they may deny any responsibility after the item is shipped. Why I always pay for tracking and prefer to buy using Paypal or Amazon.

If you waited longer than the dispute window you’re at their mercy. Keep track of your dispute windows!

Back somewhat on topic… Anyone know if Thrunite ever got their QC issues resolved with the 2A V2? I’d still love to grab one of these, but reports of high standby drain really killed the deal for me.

I can’t answer whether the issues have been addressed or not, but I have owned one of these since the beginning and it works great on a single 14500. Which is great since this is how i run it.

However, it is very temperamental if it has to run on any combination of AA or Eneloop to the point of not working at all. Adding insult to injury, the switch is difficult to find in the dark.

The 2Av2 can be used in 1xAA or 2xAA configuration.
Working Voltage: 0.9-5V

so it could be used with 1× 14500

sorry all images down
thanks photobucket
