Review : ThruNite Neutron 2C V3 (with ramping firmware)
« on: December 22, 2017, 06:28:00 PM »
This is the ThruNite Neutron 2C V3 (newest version) sent to me for review from ThruNite and NO other compensation other than keeping the light.

Light can be found at the main ThruNite site …. is external)
 (20% off during the Christmas sale on the main site.)
 or at the Amazon link …. is external) …. (Links are NON Afilliated)
I know I am posting this a little late for Christmas to get the light for anyone who may want it by then , but I have had a number of things cut into the time I could spend getting the review finished with the holidays coming up and just everyday life , so my apologies for not getting this posted sooner.
I will start by saying the Neutron 2c V3 is a very nice light from the time you get it out of the box , as it just has the look and feel of a quality light , which I have come to expect with the ThruNite products.

The package comes with the instruction manual and thank you card , the ThruNite 3400mAh cell , USB charging cable , 2 extra USB port covers , 2 extra O-rings , an extra rubber boot that goes under the side switch and detachable clip.

This latest upgraded model has the XP-L V6 emitter in it and comes in a cool or neutral white. The emitter is well centered inside the somewhat deep reflector (for a tube style light) and the reflector itself looks pretty much flawless. The lens is AR coated and the Anodizing is very well done. The knurling is somewhat aggressive , but not overly so and has a really good feel to it with alot of grip. The threads are square cut , well machined and were lubed just about right when I received the light. The Neutron is also USB side port rechargeable , or you can remove the cell and charge it on an external charger if desired. The USB charging is rated at 1 amp

With the tube extension in place (or removed) The light can be used with a single 18650 , 2 × 16340 or 2 x CR123A , single 18350 or single 16340. This makes the light compatible for a number of different configurations and cells , so to me that is very big plus.
 There is NO tail switch on this new model and ALL functions are through the side switch , which is a nice looking metallic one. There is also a small indicator light in the very center of the switch button that is a constant on , blue in color , when the light is powered on. This same indicator light is also a Low voltage indicator and RED in color when the battery voltage starts getting low. The Low voltage warning will start blinking at first and when the cell is more near depleted , then the indicator light is a constant red , until the Low Voltage Protection will turn the light off when the cell gets to the low voltage level. (Noted in charts below)

The indicator light also functions when using the USB side charging port. When the cell is depleted the light will be Red when you start charging and turns Blue when the cell is fully charged. If the cell is inserted wrong or if there is not a good connection , such as the tubes not screwed together good or a bad contact , then the indicator light will show Purple.

The driver seems to be a constant current driver that is used , but at this time I do not want to try to get the light apart and risk damage to check it , as it seems to be glued tight.

The UI is my favorite feature of this new model. It has what ThruNite calls “Infinity Modes” , most of us know it as Ramping. The ramping is used by simply turning the light on with a single quick press , then to go up or down you simply hold the side switch until the desired brightness level wanted is reached. If you are going higher in brightness and stop then then next press will go back down or if you are already going down and stop , the next press will go back up in brightness. You can achieve any level of brightness desired with this firmware , so there is always the perfect level of brightness. The ramping does move a little slower than some I have seen , such as the “Narsil” , but it does give you a little more reaction time when trying to fine tune the brightness. There is also memory , so no matter what level of brightness you are at when the light is turned off that is the level it will come back on in throughout the “infinity” or ramping mode and that level stays in memory even if you go into Turbo , Strobe or Moon. The Turbo , Strobe and Moon mode are not memorized. The Moon mode is activated with a long press from off , the Turbo is a quick double click (from any mode including off) and the strobe is another quick double click from there , a single quick press to turn the light back off.

The beam pattern on the Neutron is a semi throwy beam but with some good coverage area also. The tint I am reviewing is listed as “cool” but it is not like the really cool , blueish color that we normally associate with cool , the tint is more of a pure white to my eyes.

The light should have some good runtimes with a high capacity 18650 for sure. Due to so much going on right now with getting ready for the holidays time constraints kind of kept me from doing more run time testing than I did.
 The test I did with the included cell and the 16340 Efest cell are noted in the below chart , as well as my tested lumens and amperage with the included cell.

Overall I am very pleased with the newest Neutron 2C V3 for the overall fit , finish , feel and UI and I think ThruNite has a winner with this one.

For those who do not want to watch the whole video , the still shots of the light and the beamshots start at 9:19 of the video timeline and the live outdoor footage starts at 13:28 of the timeline.
