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.
The pocket clip is removable.Quite stably attached for this type clips.
Very nice cardboard box.
Accessories-Pocket clip,Very good Holster,Extending battery tube,Spare O-rings.
Dimensions:
- Length: 146.5mm
- Diameter: 25.4 mm(head)
- Weight:
The 2C v2 has a good anti-roll design.

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.
Perfectly centered LED on my sample. Aluminum smooth reflector.
Toughened ultra-clear glass lens with anti0reflective coating.
Identical reflector with TN12(2014) and eutron 2Cv2.All lights with a Cree XM-L2 LED.

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.
That's why I will post the same comments I did for the 2C model.
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.
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 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 excellend in all tests protecting the batteries from overdischarging.
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.
Below is a runtime graph.
Displays the Lumen otput 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.
The 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.
