Thrunite TC20 V2 Review (4000 Lumens, XHP 70.2, USB-C)

Today I am taking at the Thrunite TC20 V2. It’s not the newest model but it’s still recent and an update on the Thrunite TC20 V1. It’s running a Cree XHP70.2 LED, a 26650 battery, and has onboard USB-C charging. If you want a light that can sustain 2000 lumens for more than an hour, listen up. Thanks to Thrunite for “accidentally” sending this to me ?.

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.

 

Construction & Design

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 traded knurls for milled blocks in an almost frag pattern. 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 has a moderate orange peel. Overall small but positive design changes from the original.


Retention

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 at the tail if you wish.

 

Size & Weight

I measured the length at 118.1mm, the diameter of the body tube at 32.6mm, the diameter of the head at 42mm. The weight with the battery is 242.5g. The light is IP68 water rated.

 

LED & Beam

The TC20 V2 is running the Cree XHP70.2 LED that Thrunite says is capable of 4000 lumens. It’s available in Cool and Neutral white, and I have the cool white version here. On my Opple meter, I measured 5737 lumens, 66CRI. The tint didn’t have any green tinge to it and it seems to be a constant current driver. 

You would think this would be a pure floody light but it actually has a decent amount of throw to it at the hotspot that’s fairly tight.

Mode spacing here is less than ideal. I am very happy that it still has firefly at 0.5 lumens, but with 3 main modes to cover 0.5 to 1800 lumens, there are some pretty big jumps there between medium and high going from 350 to 1800. Another mode somewhere around 1000 lumens would be nice at least.

I will insert the output results I got from my lumen tube testing here. 

 

Heat & Runtime

The light is able to sustain it’s 3500+ lumens for 3:45 before stepping down to around 1600 lumens where it will run for 45 minutes, before stepping down to about 1400 lumens to finish out the remainder of it’s 1:45:00 runtime. Peak heat during this time was about 58C. Running on medium nets an impressive 11:15:00.

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 over an hour. 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 your looking for.

 

UI

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. 

 

Recharging

The TC20 V2 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 4.15v in 3:48:00. The curve here wasn’t as clean as I am used to seeing but nothing that I was concerned about. 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 5500mAh.  

 

Final Thoughts

The 26650 flashlight form factor seems to have kind of fallen out of popularity with the increasing availability of 21700 batteries having similar capacities, but I like the 26650 size in my hand personally from an ergonomic perspective.

One of the best features here in my opinion is probably how long this light can sustain 1500+ lumens before stepdown. That’s a feat that many high lumen output lights just can’t do due to heat and battery fatigue. This does that with ease. That said mode spacing here could be better to give you something between 1853 lumens and 320 which is the jump between high and medium.

This is going to be a good all-around use light, I think it would be a good option for something like camping or emergency prep as it’s good around, has quite a bit of life at higher lumen outputs and size isn’t as critical of a feature.

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.

Youtube Version of this Review:

Construction
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.

Charging
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
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.

Packaging
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.






Comparisons
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.


Pro

  • 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.

Con

  • 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.

Conclusion
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. Thrunite has a presale running right now where you can save 20% off the cost of the TC20 by buying from their store http://www.thrunite.com/thrunite-tc20-3800-lumen-flashlight/(link is external) (Non affiliate).
