I have enjoyed the previous lights from Thrunite that I have taken a look at and they asked if I would be interested in looking at a current model of the Thrunite 2C V3. The Thrunite 2C V3 is an all in one light with onboard charging and it’s flexible in its physical size and with the batteries it can use. Thanks to Thrunite for sending it for me to take a look at.

What’s in the package
The box is similar to other Thrunite’s I have reviewed recently. It’s a sturdy brown paper box with limited markings and information. The goodies are all in side. Included is the Flashlight itself, pocket clip, lanyard, MicroUSB charging cable, bag of spares (Oring, 2 USB port covers, and button diagram), and Thrunite button top protected, high discharge 3400mah 18650 battery. The holster is made for this light and it fits nicely. There is a plastic d-ring at the top and the belt loop is fixed.
This light is made from aluminium and is hard anodized with a smooth gloss finish. Some interesting design choices have been made to keep this light short and flexible with it’s battery sizes. Starting at the back the rear is flat and non magnetic. There is a small hole drilled for the lanyard and below that is the only place a clip attaches to the light. The clip itself is very deep carry and works well for both length of the light. The body tube is 2 pieces with square cut threading and an O ring. This design allows battery size flexibility which I will talk about more in a few minutes. The knurling is a diamond pattern and is deep and aggressive.
The head portion of the Neutron 2C has the anti roll ring which contains the electronic button with LED charge status indicator in the center. The button sits pretty flat and has a nice audible click. The microUSB charging port is opposite. It’s standard depth so any standard cable should work well. The charging cover is a smart design. It uses a larger looped piece of rubber that goes around the entire head of the light and this is what the door sealing out moisture is located. The result is it’s super easy to replace if needed.
Size & Water Rating
Length in long configuration 125mm
Length in short configuration 94mm
Width at it’s maximum 26mm
Width at it’s minimum 24.5mm
The light is IPX8 water rated.
The LED used here is a Cree XP-L V6 in Cool White, Neutral White is available as well and is my personal preference.The reflecto is smooth and fairly deep. LED centering is nice, and everything sits behind a antireflective coated glass lens.
This light can use a variety of different sizes of lithium batteries. It ships with a Thrunite button top, protected, high drain 3400mAh battery which is how I will most likely use it the most. It will also work with 2X CR123A, 1X 18350, 1x 16340, or 2x 16340. Button tops are recommended. I had some minor issues getting my flat top 18350’s working with small magnets. Working voltage is 2.7-9.0V.
The Neutron 2C throws quite well for an EDC. It has a small hot center with a moderate spill and hard cut off. It’s a pretty useful beam pattern.
I ran my runtime test with the included 3400mAh 18650 battery. In Turbo mode the light will last about 10 minutes before you see a large decline to about 65% relative output. This will go for about 60 seconds before a slow gentle decrease down to 10% relative output when the Low Voltage Protection cut in. Low Voltage cut off with the included battery was 2.93V. I measured parasitic drain at 0.3uA.
UI on this light ramps. That means there isn’t defined modes for the most part. Using a long press from off and the light enters firefly mode at 0.5 lumens. Long press again and you get to what Thrunite is calling Infinity Low at 12 lumens. Here is where the ramping begins. Long pressing again and the light begins increasing in brightness slowly. It takes 6 seconds to reach Infinity high at 650 lumens. Double click at any time to reach Turbo at 1100 lumens, and double click again to reach strobe. When in the ramping modes you can stop at any time at the desired brightness. If you long press again it will begin decreasing. The light will flash at both high and low ends to let you know you have reached the maximum or minimum.
Recharging is accomplished via the microUSB port opposite the switch on the light. Unfortunately the light only recharges at a maximum speed of 1A. This means it’s a bit slow to recharge. In my test it took 4 hours and 52 minutes to recharge from 2.93V to 4.2V. The LED button contained within the button of the light acts as both a battery level indicator while the light is in use and a charging indicator while charging based on the color and blink pattern.
- Available in Neutral and Cool White emitters
- Flexible in output to whatever level desired, but the ramping is a little slow.
- Flexible in length and battery
- 3400mAh high drain 18650 battery is included.
- 1A recharging is a little slow. It would be nice to see this move up to 2A.
- The ramping output of the light doesn’t cover the entire range. Nothing between 650 lumens and 1100 lumens. Ramping is only available between 12 lumens and 650 lumens.
The Thrunite Neutron 2C V3 packs a lot of features and flexibility into one small package with a nice UI. I would like to see ramping be a bit faster and cover the entire range of the lights output ability. That said it’s an all around nice light that really give the user a lot of flexibility in what battery they they want to run (Or what’s available), flexibility to in the length of the light without any extra parts to buy, option of the emitter tint, and flexibility to charge onboard via microUSB. Overall I think this is a light that will appeal to both enthusiasts and non flashaholics.
