Klarus XT11 GT Pro Review (2000 Lumens, Cree XHP 35 HD, USB-C,18650)

Today I have a newer light from Klarus the XT11 GT Pro. This is an update to a light that Klarus has made previously. Klarus (Affiliate) sent this to me earlier in the year for review, and I appreciate their patience as it took me a little while to get to it.

Construction

The XT11GT Pro is made from aluminum and is anodized in a smooth medium gloss black anodizing. Visually it’s different then the standard XT11GT. It features the same tactical tail cap, with the large center button being a mechanical switch with a grippy silicon cover and the paddle on the side to allow for mode selection. The paddle was upgraded to aluminum here for incredibility. The clip is a clip on, non fixed and rotates around the body of the light. It’s not deep carry with it leaving about 32mm exposed from a pocket. 

The body is milled with small horizontal lines going around the body of the light and then it has small relieves milled in. It’s a nice change from traditional knurling and provides a good amount of grip. The threads are nice and square cut and it’s a dual wall construction. The head and body tube appear to be once piece. As we get to the head of the light it grows in size, It’s got a built in anti roll ring that adds some style and nicely disguises the USB charging port cover. This is definitely one of the better designs I have seen for this. 

The bezel is a little aggressive and the outer edges have some sharper sides. It’s a gunmetal color and stainless steel I believe. It’s easily unscrewed by hand. Inside is a anti reflective coated glass lens, a fairly deep smooth reflector 

 

Size and Weight

I measured the length at 139mm, minimum diameter on the body at 25mm, maximum diameter on the head at 35mm. Weight with the included battery and clip was 169.2g. 

For an 18650 light it’s a little on the long side, but that’s not unexpected with the deeper reflector. Here are some comparison shots with the light and some others.

 

Retention

Your 2 Retention methods on this light is with the included pocket clip. Unfortunately this isn’t deep carry carry with about 32mm of the light exposed if you do decide to use the clip. With the size of this light that’s ok, as I think it’s more of a bag or coat light myself. The included holster does the job pretty well too, no complaints there. 

 

LED & Beamshots

The XT11 GT Pro is using the Cree XHP 35 HD LED in cool white at 6500k. This is an interesting choice of LED”s since it’s officially been discontinued by Cree. That said plenty of existing stock still exists and Klarus must feel like they have enough to meet the expected demand of this light. The beam it’s self is a good all arounder. The deep smoother reflector means the light has a fairly small hotspot and it throws pretty well but there is also spill to allow for short and medium range light. So a good all around beam. 

The light will run on 18650 batteries which is how I will use it, but it will also run on 2x CR123a batteries which is nice as a backup. As a result the working voltage is 2.8V to 6.4V/ No PWM was observed. 

 

Runtime & Heat

I measured runtime with the included 3100mAh battery. Turbo runtime was 50 seconds before stepping down to 90% and then it ran for another 2 minutes 10 seconds before settling at 30% relative output where it ran for an additional 1:37:00. Total runtime was 2 hours. Max Heat I saw was 42C at 1:35. 

 

UI

Like many of Klarus recent lights this has 2 modes of operation, a Tactical and a Outdoor setting. The tactical mode allows the main button on the rear of the light to go to turbo, and the paddle to be a shortcut for strobe that you can lock on by holding for 2 seconds.

I primarily tested the light in it’s outdoors setting though. When in this setting the primary button on the rear is a shortcut to turbo both as momentary or locked on. Once on you can use the paddle to decrease the modes from turbo, high, Medium, and low. You can also use the paddle when the light is off to start in moonlight mode and then increase in output for each push. It’s a system that works better then I expected and is pretty intuitive once you use and get it.  

 

Recharging

One of the updates the XT11 GT Pro has is USB-C charging. Unfortunately it doesn’t support USB-C to C or USB-C PD charging. So you need to use the supplied (or similar) USB-A to USB-C cable to charge the light. The port cover here is nicely shaped and fits well into the side of the head. It’s one of the better executions I have seen of this in 2020. 

I charged the included 3100mAh battery from LVP to full in a total time of 3:23:10. It wasn’t the fastest charging rate, as the maximum I saw was right at 1A. There is a small LED indicator light built into the side of the light to act as a battery charge state indicator. Green is anything more then 70%, orange is between 30-70%, and red is less then 30%, red flashing is less then 10%. 

Packaging

My light is a super early production light (Serial number 17), and doesn’t have a box so I can’t comment on that. I can tell you the accessories it came with. My light came with a 3100mAh button top protected IMR 18650 battery, a Klarus branded lanyard and a USB-A to USB-C charging cable. It also came with a nylon, Klarus branded holster. It has a Dring and velcro belt loop. It seems to be solidly made. 

 

Pro

  • I like the outdoor UI setting here once you get the hang of it but it’s a little different.
  • Nice size in the hand for an all around light if you want your buttons on the rear.


Cons

  • Seems expensive
  • Cool white only
  • No true moon light mode, lowest is 10 lumen output
  • No USB-C to C compatibility and slow charging

 

Conclusion

My conclusion for the Klarus XT11GT Pro is that it’s a good all around light general purpose light. The 2 UI modes allow you to use it tactically if you want or use it in the outdoor mode which is more appropriate for everyday uses like power outages and camping. The beam is useful with enough throw and spill to do both jobs pretty well. What I don’t care for is the asking price I am seeing at the time of filming. It’s high in my opinion currently. Around $50-60 would make it a good value but at nearly double that I would struggle to pay full price. So if you’re interested I would watch for a sale or coupon.

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.
