Today I am looking at the Thrunite TN12 Pro, it’s a slim form factor 18650 light, optimized for a throw, and tactical applications, but can serve that EDC roll as well for those that prefer a tail cap switch and turbo shortcut. Thanks to Thrunite for sending this to me to review and show you guys.

Packaging & Accessories
The packaging here is standard Thrunite, protective, nice but not over the top. Accessories that come with the light, is the 3400mAh button top protected 18650 battery, lanyard, orings, spare port cover, pocket clip, nylon holster, USB-A to C charging cable, and manual.
Design & Construction
The TN12 Pro is made of hard anodized 6061 Aluminium and features a mechanical switch in the rear with a textured button that is a shortcut to turbo. It has protective rings around it which feature a milled-out area for the lanyard. The pocket clip mounts at the rear. The body section has small, deeply milled lines that provide a significant amount of grip but shouldn’t rip things up. The head section is glued to the body. The head is similar to most other Thrunite designs with the same style silver button, with a voltage indicator LED in the middle with an antiroll ring around it. The bezel is not removable but does have rounded crenulations to allow light to leak out if placed face down. Inside the reflector is smooth and deep. The lens is AR coated. Inside the light has a fairly stout spring at the rear as well as the front. It’s a dual wall light to allow for the use of the front and rear buttons.
A note on the name here, Thrunite has traditionally used the TN naming for lights that didn’t have onboard recharging and used TC for lights that had onboard charging. They through out history when choosing the name here as it’s a TN but does have onboard recharging. Labeling here is minimal just the brand and model number on the front, and directly opposite the required markings and serial numbers. Other brands should take note of how small and minimal this branding is.
Retention
Retention options are several here, first, you have the branded lanyard that can attach at the tail if you wish. You also have the nylon holster the light comes with, it’s one that Thrunite uses with other lights this size, plastic Dring, sewed dring, elastic side, and soft interior.
The last is the pocket clip which mounts at the rear of the light. It’s a dual direction clip so it can be clipped to a hat if you want. While this isn’t as deep of carry as I typically want on an EDC, you rarely get that on a tactical light, so the 0.85” that sits above the clip is ok.
Size & Weight
I measured the length at 5.15”, minimum diameter at 0.94”, and maximum diameter at 1”. I measured the weight at 5.07oz with battery and clip. Thrunite rates the TN12 Pro as drop resistant to 1.5 meters and IPX-8 water rated.
The main competitor to the TN12 Pro is probably the Olight Warrior Mini 2. The Thrunite is larger in all dimensions as well as weight which came in 0.82oz heavier, without the magnetic tail cap properties of the Olight, although these are mainly for charging.
LED & Beam
The LED being used here is the Luminus SFT40 LED in cool white. I measured it with my Opple Meter at 6000k 65 CRI. It’s a flat top LED in a relatively small package. The resulting beam is a small hotspot and very minimal spill. The throw is this light’s main thing and it does that well out to a claimed 380 meters. Some people have complained about coil whine on high mode, but it’s not something I can personally hear here. There is PWM but it’s very fast.
Output Measurements
Here is a chart for my measurements of outputs using my DIY Lumentube. Everything was pretty close except for Turbo I couldn’t quite get to the claimed 1900 lumens.
Heat & Runtime
I will try to let the graphs do most of the talking in this section and point out a few high points. Turbo runtime was good for about 2 minutes, jumping from near 1800 lumens to 800, in what looks like a thermal regulation with temps reaching 56C. There is one more step down to 400 lumens gradually out to the 7-minute mark which is where Thrunite gets the 7-minute runtime number from.
Turbo and High modes had very similar output curves with the only difference is really where they start at. Medium mode ran out past 6 hours. In all modes, the light runs at the end in low/firefly for several hours.
UI
UI is similar to Thrunite’s standard UI, but with direct access to only Turbo on the tail cap. The light has the normal Eswitch up front and mostly normal UI there. Long press from off to go to firefly, however long pressing again shuts it off instead of going to low. Once in low, you can press and hold to cycle between low, medium and high. To access turbo double press the front switch or just turn on the rear tail switch. To get to strobe triple-click the eswitch. There is memory mode, here when the eswitch is used for low, medium and high only. As a result of the construction here there is no mechanical lockout.
I did notice one UI feature that I think maybe a bug. When in medium mode if you leave the light for a few seconds, hit the button again expecting to bump up to high mode, instead the light bumps down to low.
Recharging
Recharging here is accomplished via USB-C port that is capable of charging via C to C and or PD. Max charge rate I saw was 1.7A without issue in a near-constant current charge mode till the end. The total charge time of the included 3500mAh 18650 from LVP at 2.93v was 2:46:00. Full charge was measured at 4.18v.
The port cover here is worth mentioning. Like many, it’s rubberized silicon that pushes in place. They have a little dovetail to help keep it in place, but I find it kind of hard to push in and keep in place when in use. I found if I push the cover in and then pull it to the front of the light, it’s easier to put it in the dovetail and keep it in place.
Final Thoughts
I have mixed feelings on the TN12 Pro, it’s not radically different from other models, but it’s a pretty great value if you’re looking for a throwy 18650 with onboard USB-C charging, cool white, and instant-on Turbo via the tail cap.
For me, this doesn’t meet my EDC needs, but this isn’t really where the design is focused, as I feel like it’s more on the tactical side of things with EDC being a second thought. I had a hard time putting the port cover in place and keeping it there, it’s like the silicone is just slightly too long.
Overall it’s a good value right now with the coupons that are being offered on Amazon for a complete kit light if this niche is what you’re looking for and I think you will be happy with it. However, this isn’t different enough that I would rush out and buy it if I had a previous version or a light that did something similar.
