Thrunite – TC20 Pro Review (3294 Lumens, 350 meters throw, USB-C, 20%)

Today I am looking at the Thrunite TC20 Pro. This is an updated version of the TC20 V2 that I looked at in the past, and the main difference is that the Pro is using a Cree XHP 70 HI LED and smooth reflector. As a part of this review, I will be comparing it to the Fenix PD36R Pro during my night shots section later on. Thanks to Thrunite for sending this to me to look at and offer an unbias review. Any discounts or deals I have for the TC20 Pro will be in the description below along with links to my social media accounts that I encourage you to go and follow.

Packaging & Accessories

Standard Thrunite brown cardboard box here with the elastic band, I would call it functional minimalism. Inside is the entire kit with almost everything you need to maintain and use the light for years. You get the light itself, a 5000mAh 26650 Thrunite battery, nylon holster, USB-A to C charging cable, lanyard, a bag of extras including o’rings, button seal, USB port cover, and split ring, a manual, and warranty card.



Visually and construction-wise, the TC20 Pro is pretty much identical to the TC20 V2, with the main differences being the LED and Lens combination. The light is made from Aluminum and hard anodized black. Build quality is always good from Thrunite and this is no exception. The tail cap provides a flat surface that allows for tail standing and has a lanyard hole. The cap is removable and non-magnetic. Inside there is a stout spring on the tail end only.

The body tube has milled blocks in an almost frag pattern for grip. The corners are well-chamfered though so it’s not too aggressive. Square threads on both ends are anodized, smooth, and nonreversible.

The head features the standard Thrunite electronic switch with a metal button on top, and a small battery indicator LED in the middle. Directly opposite the button is the USB-C charging port that’s covered via a silicone rubber flap. It’s decent fitting and does stay out of the way. The light has moderate milling at the top for heat dissipation and weight reduction. The bezel is flat. The lens is AR coated and the reflector is smooth.



UI here is Thrunite’s standard. Single press to turn on, long press once on to cycle up between the 3 main modes, double press to go to Turbo, triple press to go to strobe. It’s a very simple interface, and it’s easy to use which is nice but also limiting. A fast ramping interface would work pretty well here too given the limited number of modes and wide range of outputs it must cover. 



Retention options include the included nylon holster. It has elastic sides, plastic dring, and a fixed belt loop. It gets the job done but is just of average quality. The light also comes with a branded lanyard and split ring that can be attached to the tail if you wish.


Size & Weight

I measured the length at 118.1mm, the diameter of the body tube at 32.6mm, diameter of the head at 42mm. The weight of the TC20 Pro with the battery is 242.5g. The light is IP68 water-rated to 2 meters. Here are some comparisons with other flashlights, including the Fenix PD36R Pro I will be comparing it to in the night shots coming up soon.

LED & Beam

The TC20 Pro is using a Cree XHP 70 HI LED in cool white. On my Opple meter measured the tint at 6092k and 69 CRI. DUV is fairly neutral with no major tint shifts. When I compare it to my TC20 V2, it has much less tint shift and much less yellow/green, especially at lower outputs. The beam on the TC20 Pro is more spotty and throws a bit further and that makes sense with the smooth emitter and dedomed LED. When I compare it to the Fexnix PD36R Pro the hot spot is of a similar size but has a smoother transition into the spill where as the Fenix is much more pronounced. I would say the tint of the Fenix is more green, especially at lower outputs. There is a small amount of very fast PWM on all modes of the TC20 Pro.



Heat & Runtime

The light is able to sustain it’s 3500+ lumens for 3:30 before stepping down to around 1800 lumens where it will run for 32 minutes, before stepping down to about 1600 lumens to finish out the remainder of it’s 1:00:00 runtime. Peak heat during this time was about 59C. Running on medium nets an impressive 9:30:00.

Where this light really shines in my opinion is the amount of time it can sustain well over 1000 lumens. This light maintains over 1400 lumens for 1:40:00. I frequently get asked what light can I buy that will stay over 1000 or 2000 lumens for an hour, well here is a good option for you if that’s what you’re looking for. In comparison to the TC20 V2 the Pro here doesn’t have quite a long of runtime but that’s to be expected with this different LED and more overall output.



The TC20 Pro has onboard USB-C charging that’s protected by a silicone rubber port cover. I charged the light charged the light from LVP to full at 4.17v in 3:17:00. You are able to use the light during charging but only in low and medium modes. It charges via USB-C to C or PD without an issue. While the included battery is officially rated at 5000mAh, I tested mine with my Vapcell S4 Plus at 5437mAh.  



The Thruntie TC20 Pro is a worthwhile upgrade to the V2. It takes what was a moderately floody light and increases its ability to throw, while still maintaining the size and form factor we know. The tint here is better on the Pro, and over it’s competitors in my opinion, and I prefer the beam tint and shape on the Pro. You do take some small decreases in overall runtime though due to that higher comparison. 

Compared to the Fenix PD36R Pro, the TC20 Pro is less tactical with it’s UI and a bit more general purpose in my opinion. It’s also generally a better value and a light I can recommend over either the TC20 V2, or the PD36R Pro dollar for dollar in my opinion.

Packaging & Accessories

Standard Thrunite packaging here that I will let the photos do the descriptive work. While the box does note that a NW emitter is available, it’s not out at the time of review. Accessories that come with the light are the flashlight itself, a Thrunite branded standard 3100mAh 18650 IMR battery, branded lanyard, USB-A to USB-C cable, 2 extra orings, spare USB port cover, pocket clip, nylon holster and assorted paperwork. 


Construction and Design

The TC15 V3 looks a lot like the previous TC15 V2. Starting at the tail cap it is mostly flat with a small indent, and non magnetic. Your lanyard attachment point is on the rear. There is no knurling on the light, with only flat areas milled in the tail cap for grip to remove the battery. The body tube has flutes milled into it for style and a bit of grip. As mentioned in the retention section the clip only attaches in the middle of the light and the body tube is not reversible. 

Internally there is a spring at the tail, and a solid post in the head. Threads on both ends are square cut, lubricated and anodized. The head has a anti roll ring where the button sits. It’s the same e-button Thrunite has used on many other lights and tolerances are good, no side to side movement. It makes a nice click and requires slightly more force than normal to push. The charging port here is 90 degrees to the right of the button, in a very slim silicone cover that stays out of the way.

The front is one piece, no extra bezel, what bezel is there is smooth. The glass lens is slightly recessed and has AR coating. The reflector has an orange peel and is deep. 



Retention options on the TC15 V3 are pretty typical with one asterisk. Thrunite does include nice branded lanyard that attaches on the tail cap. You also get a branded holster, it’s ok, mine had lots of loose strings and felt kind of thin. 

Lastly is the clip on the TC15 V3. It’s changed from being mounted near the tail, to mounting in the middle of the body. It’s a dual direction clip but backwards from how I would carry this light, head down. That means to carry it head down you have to lift your pocket over the rather large bend of the clip. Once you do that it carries pretty well but it’s just not easy to put in the pocket like pretty much every other knife or light with a clip. Oh and for those suggesting you rotate tube so the pocket clip carries more traditionally you can’t. The thread line up but it doesn’t make electrical contact due to a 1mm difference on the head side. Not a fan of this design personally. 

Size and Weight

I measured the length of the TC15 V3 at 122.5mm (4.82”), minimum diameter at 23.5mm (0.925”), and maximum diameter at 25.6mm (1”). Weight with the included battery and clip was 134.5g or 4.74oz. The light is IPX8 water rated and 1.5M impact resistant. Here are some comparison shots with similar sized lights you might have. Branding is pretty minimal on this light which is great. 

LED & Beam

The TC15 V3 is using a Cree XHP35.2 LED. As of the creation of this video it’s only available in cool white. My unscientific Opple Meter registered this at 7000k in turbo with a CRI of 72 in the center. The beam has tint rainbow, with the beam getting green around the spill. The beam shape is a medium sized hotspot in the center and large amount of spill. This light does have PWM, but I don’t notice it with my eye. I will throw up what the meter shows in medium mode. I measured parasitic drain at an acceptable 47uA. 


Thrunite lists the official outputs as the following.


Heat and Runtime

For my runtime tests I measured the % of relative output at the 30 second mark to set what 100% relative output is according to the FL1 Standard then let them run. I did this with the supplied 3100mAh battery fully charged. 

Turbo ran for 3 minutes stepping down gradually as heat increased. From here it ran for 1:20:00 before 2 final step downs for a somewhat short total runtime at 1:35:00. Maximum heat was recorded at 1:20:00 at 46C. I then compared Turbo, High, and Medium runtimes and there really is not much difference between Turbo and High runtimes, less than 5 minutes. However medium ran out to 4:10:00. I did test low but didn’t graph it, it clicked in an impressive 58 hours and 17 minutes which is longer than The United claimed runtime. 



The UI here is pretty simple. When the light is off, a quick press turns it on in the last mode used (memory), a press and hold lets you cycle through the 3 main modes (Low, Medium, High). When on double press to go to Turbo or Triple Press to go to strobe. When going to turbo or strobe the light does blink to off for a second which isn’t my favorite thing. From off long press to get to firefly mode, to lock/unlock from firefly press and hold to lock. 


Battery and Recharging

The TC15 V3 comes with a Thrunite branded 3100mAh IMR battery. This is a standard button top battery which is great to see. The light charges via the USB-C port on the side of the light. It is USB-C to C compatible and USB-C PD compatible. I charged from LVP at 2.94v to full at 4.1v in 2:17:04. It’s worth noting that charging speed here hit 2A almost immediately and continued at this rate for the first hour. Not a ton of light actually hit and hold 2A charging. Make sure you have a high quality power supply though to hit this. 

Final Thoughts

The TC15 V3 is mostly a win for me. It’s a nice size, easy user interface, and uses standard batteries with onboard USB-C charging. The pocket clip is what doesn’t make a ton of sense to me, it really should be flipped to the tail for deep carry, or mill the body so you can mount it in either direction. Both would be great solutions and improve the carryability of this light. As is to carry it head down it’s basically a 2 hand operation to put it back into your pocket. Not idea in my opinion.

I do hope we see a NW emitter for the TC15 V3 some day, it’s a personal preference of mine and something Thrunite has been good at in the past. I hope this isn’t a situation of slower sales of NW emitters causing the company to choose not to come out with that option. 


So if your looking for a good quality general purpose, non complicated 18650 flashlight with an easy UI and good customer service, look no further than the TC15 V3.

Thrunite TC20 Review (XHP70.2 NW, 26650)

Thrunite gets a lot of positive attention with their flashlight models. I previously didn’t have one to review until recently with the TC20. The TC20 is one of the more recent designs from Thrunite(link is external) and I am glad they were able to send it to me for review. This is a 26650 based light, in neutral white capable of producing 3800 lumens and is microUSB rechargeable at 2 amps. Let’s take a closer look at it.

Full Image Gallery for this Review: is external)
Youtube Version of this Review:

The TC20 is made from aluminum that’s been semi gloss black hard anodized. Machining is good with no sharp edges and everything lines up like it should with any printing, and flats on the body. The tail is non magnetic and slightly recessed. There is a small milled out area to attach the included lanyard as well. The tail cap and about ? of the body tube have a diamond knurling pattern that’s more on the aggressive side without being too aggressive to damage pockets. The head is milled from what looks like a solid piece of aluminum. It has 5 flats milled into the ring around the power button which helps control roll.

The button itself has a positive feel to it and makes an audible click. I believe it’s a metal top, with an LED in the center to indicate battery power level and charge status while charging. The reflector is deep and and has a nice orange peel to it. The glass lens is anti reflective coated. The silver colored bezel is removable and is used to contain the lens and reflector. Threads are large and square cut and unanodized. The spring in the tail cap is a double spring design.

Size and Weight
Length of the TC20 was 118.4mm, Maximum diameter was 42mm, minimum diameter was 33.55mm and weight was 238.7 grams. Compared to my Olight R50, it’s length was 132.4mm, it’s maximum diameter was 42mm, the minimum diameter was 33mm and weight was 258.8 grams.

The TC20 is IPX8 water rated which is great for a microUSB rechargeable light. Parasitic Drain was measured at a low 2.0uA.

LED + Runtimes
This light uses Cree XHP70.2 in neutral white as its emitter. I have tested a couple of other lights with the XHP70.2 and found the color rainbow effect where the tint of the beam is to be uneven. It was most noticeable on the eddges of the beam. However on the Thrunite TC20 this was much less noticeable, at distance outside I didn’t notice it at all. The LED is nicely centered in the reflector as well.

Outputs are good for a neutral white XHP70.2. I don’t have a way to independently verify Thrunites claims but in reading other reviews they appear to be accurate. Turbo is rated at 3800 lumens, High at 1800 Lumens, Medium at 320 lumens, low at 38 lumens and firefly at .5 lumens. Interestingly strobe is rated at 2280 lumens. Throw is rated at an impressive 320 meters.

Runtimes were close to what I expected with this light. Turbo starts to decline pretty rapidly which was a little disappointing, but high held for about 7-8 minutes. At that point the light was producing about 55% of its output and it saw one more decline where it held steady at about 40% of it’s output for about 90 minutes. This is still a significant amount of output for an extended period of time. At the tail end it was a pretty fast decline to zero where the low voltage protection kicked in and stopped output. Turbo to flat runtime was about 110 minutes.

One thing that’s interesting is in the manual it says not to use turbo for more then 10 minutes to protect the light, battery and it’s components. The light does get warm to the touch but never so hot that it feels dangerous to hold or like it could be damaging the light.

Beam Pattern
The beam pattern is pretty even, there isn’t a significant hotspot but there is a small less noticeable one. The beam is primarily flood but has a good amount of throw to it as well. In my outdoor shots you will see how well it really lights up a large area that’s approximately 100 yards in length. It’s a really useful beam in my opinion for general use especially when your looking to light up a large area at one time. See the video for more.

The light has built in USB charging via microUSB opposite the main mode button in the head of the light. To cover the port there is a beefier rubber cover that can be rotated out of the way. It can charge at a rate up go 2A which helps with charging speed greatly with the high capacity 5000mAh Thrunite button top 26650 battery that is included with this light. The light also works in Firefly, Low, and Medium mode. Thrunite includes a high quality USB cable with the light as well which I recommend using. If you see charging take over 2.5 hours make sure you look at your power source is providing a reliable, clean 2+ Amps.

UI on the TC20 is basic and pretty logical. I like how they have chosen to keep strobe out of the main group of 3 modes (Low, Medium, and High). Turbo is accessible from any mode with a double click. Getting to strobe is slightly more difficult than other lights. You have to first be in turbo by double clicking and then double click again to go to strobe. I like this as I rarely have a use for strobe.

Moonlight mode is only accessible when the light is off by pressing the button and holding until it turns on. This light does have memory mode for the main 3 modes and you can return to it by just clicking the button once quickly. There is no software lockout mode.

The light also has a power capacity indicator in the main button. At 100% power it is a steady blue, at 11-20% power it’s red, at between 1 and 10% power remaining it flashes red.

Thrunites packaging is a nicely executed and minimalistic. The light comes in a brown sturdy box with a line drawing of the TC20 and minimal info. It was held together with a clear rubber band. Inside is the lightself protected via foam with the battery preinstalled but using a contact protecting plastic disk that needs removed prior to first use. Under the foam is the USB cable, lanyard, holster, spare orings, side switch cap, and manual.

Compared with my Olight R50 which also has MicroUSB charging, and a 26650 battery the Thrunite TC20 is a shorter more compact design. It’s head is a bit smaller in diameter too. Knurling on the Olight is different, less aggressive. I do like the Thrunites more aggressive feel in the hand. Both fit well in my medium sized hand. The Olight has a beam that has a hotter spot and is designed for a bit more throw. It’s spill is less intense and has a harder cut off. The Thrunite TC20 beam is more even and seems to cover a wider angle. It’s neutral white LED really help bring out the natural color of things which I really prefer. Both are good lights lights, but for me the Thrunite TC20 wins out due to it’s slightly brighter, neutral white LED, and standard battery.


  • Relatively fast 2A charging on the included non proprietary 5000mah 26650 button top battery.
  • Neutral White Tint – but it does have some Cree Rainbow
  • Simple UI & Good mode spacing with Firefly
  • Nice fit in the hand and more compact than other similar lights.
  • I like that they include an extra side switch cap in the packaging.


  • Cree XHP70.2 has some noticeable color shift across the beam, this has been similar across all of the XHP70.2 lights that I have reviewed, this is less noticeable at a distance.
  • No software lockout mode, but mechanical lockout works.
  • The holster is pretty basic, but functional.

I like this form factor for a light, it’s a good general purpose size for non pocket EDC uses. It would make for a great camping light or day/night hiking due to it’s runtime and good mix of throw and flood. For me it fits in the hand well without being too big or to small. I really like that Thrunite offers neutral white tints on many of their lights. I quite like this size of light, how well it tail stands and how much light it produces for a good amount of time without getting too hot.
