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.

Jetbeam TH20 Guardian (2020) Review (3980 Lumens, XHP 70.2, 21700, USB-C)

The Jetbeam TH20 Guardian is an updated version of the previous popular TH20 Tactical flashlight. It’s rated for 3980 lumens from a Cree XHP 70.2 LED and a 21700 battery. It features onboard USB-C charging and has a powerbank function. Thanks to Jetbeam for sending it to me to review.

Packaging and Accessories

Packaging is standard Jetbeam hanging design with a nice photo of the light on the front and stats on the back. Inside accessories include the light, a 5100mAh 21700 battery, a belt holster, wrist lanyard, the USB-C OTG cable for charging and using as a powerbank, and then some nice spare red orings. Paperwork includes the manual, warranty card and COA. 

 

 

Construction

The TH20 is a solid well built light all around. Starting at the tail cap it has 2 large square ears that protect the button and paddles well, and allow for a place for the lanyard to fit. The light will tail stand but it’s not very stable when doing so. The knurled areas on the tail and body are on the smoother side but the milled areas on the light and heatsync give you an area to lock into. 

Threads on the inside are anodized, square cut, beefy and really smooth. Other manufactures take note, this is how it’s done. The tail cap has dual stiff springs, but the head only has a brass post, a little surprising for a tactical light. No issues with vibration though. 

The head section has a section that looks like heatsyncs, I think it’s more style though, The front bezel seems to be glued in place, I can’t get to move, It’s short but has large crenulations allowing light to spill out. The antireflective coated glass underneath is thick and well protected. Under that is the deep orange peel reflector and the large Cree XHP 70.2 LED. 

Size & Weight

I measured the overall length at 161mm. Maximum diameter on the head was 40.21mm and minimum diameter on the body was 29.5mm. The weight I measured with the battery, was 267.3g. This is a large light, no ways around that. See the photo below for some photos of similar 21700 sized lights. 

 

Retention 

This isn’t an EDC light to put in your front pants pockets, instead you have a holster option that the light comes with. It comes with a nylon holster, with a button belt loop and no Dring. The material here is nice but the stitching is all single stitch and it it’s not a premium feel.

LED & Beamshots

This light is using a Cree XHP70.2 LED in cool white. No tint data is given but it’s definitely cool white and has the characteristics of a XHP70.2 LED. So that means it has some beam distortion in the center, of a corona donut and then tint shift across the beam. It’s more a flood but the beam isn’t even, so I would call it on the floodier side of a typical flashlight beam. Definitely not a thrower.

The light has 4 solid on modes and then strobe.

  • Turbo 3980 Lumens
  • High 1500 Lumens
  • Medium 350 Lumens
  • Low 25 Lumens

No ratings are given for strobe but I would guess it’s equivalent to high or turbo.

 

Runtime & Heat

I am skeptical of the claimed 3980 lumens, at least that it can sustain it for any time. In my runtime graph here I see about 20 second before the light has stepped down. At this point it can sustain this mode for about 10 minutes before stepping down again due to thermal constraints with the maximum temp it sustained was 40.5C. Total runtime ended up at 2:26:00 but instead of shutting off the light ran for several more hours at basically moonlight mode. I stopped the test at 5:35:00. LVP kicked in at 2.946V.

UI

UI here is quite simple. You have a large mechanical button on the tail end of the light covered in a large silicone switch, it’s quite stiff, you won’t accidently press it, but it is loud. Next to it on both sides are metal paddles. When the light is off, the paddles give instant access to the strobe/sos mode of the light in a momentary manor. When you press the main button on the light the paddles give you mode options give you mode selections, with memory. The easiest way to lock the light out is mechanically by just turning the tail cap slightly.

 

Recharging

The TH20 offers charging via USB-C, but doesn’t support C to C charging. It features USB-A to USB-C which seems to be all most flashlights offer. Recharging the included the 21700 5100mAh battery from LVP to full took a total of 5 hours even, with peak charging rate 1.87A. The curve is a little abnormal but no big concerns with a battery this size. My one complaint is the LED light that gives the charging status is very close to the port, and combined with the port cover it can be hard to see depending on the cable you’re using. Charging stopped at 4.149V. 

The light can also be used as a powerbank. It comes with a USB-C to USB-A Female adapter cable that can be used to charge your phone or other device from the light. It can also charge a device like my phone with just a USB-C to C cable. I did a discharge at 2A, but when doing this it didn’t seem to step down gracefully like I would expect or it could be my equipment, not many lights do the powerbank feature. 

Pro’s

  • I like the warm gray color of the anodizing
  • Feels well made, and beefy, buttery threads.
  • The battery bank feature is nice in a pinch.

 

Con’s

  • Turbo is too short only lasting about 20 seconds.
  • Definitely has some distortion in the beam from the lens and LED.
  • It’s big, and on the expensive side.
  • While it tail stands, it’s not stable when doing so.

 

Conclusion

I don’t have a ton of use for a light like this in my daily uses. It’s large, heavy and turbo is too short to be useful for me on my example. I do think the tail design is pretty decent for direct access to strobe in a tactical situation but 3 simple light modes plus turbo for your solid modes. I wish turbo lasted longer then 20 seconds, it would be useful in tactical and non tactical situations. 

 

I love the color of the anodizing here, it’s gray brown anodizing, nice to see especially on a tactical light. The light is also very well built from what I can tell. Solid, and the rear switch takes quite a bit of pressure to push. If you need a solid well built tactical light thats in that middle ground between a flood and thrower then this fits that need, but isn’t going to be your best general purpose light in my opinion.
