Wuben X-2 Owl Review (3X LH351D, 1800 Lumens, USB-C)

Wuben is back at it with another Kickstarter project, this time with a smaller version of the side by side X series light using 2X 14500 batteries and 3 LED’s. Wuben sent me this early production prototype to take a look at and help them promote the Kickstarter campaign for the light. The Kickstarter ends December 1st 2022, so if you are watching this before then make sure to check out the link in the description below, and if not ill try to find some links to where you can get it after.

Packaging & Accessories

Since this was a prototype it didn’t come with a box, or any of the accessories. If you buy one I would expect a full retail box, charging cable, and lanyard at a minimum. 


Construction & Design

The looks of the X-2 Owl is similar to the X-1 Falcon that I took a look at a few months ago, but smaller. It’s the same design language as the X-1 headlamp that Wuben also debut in 2022. So more squared off, sharp angles, and kind of a cyber space-aged type look.

The light is made from aluminum and is being offered in 3 color options, a standard black anodizing, a gradient ramp that’s a white fading into blue, and then the “white” MAO version I have here. I’m becoming a fan of the Metal Arc Oxide coating look even though it’s not the most durable finish around. The front and rear pieces are black and I think this is smart as it should help with durability. There are also going to be copper versions, and 4 different anodized titanium versions too. The light is offered in two LED options, the Samsung LH351D, and an Osram P9. Not every LED and body material/color combination are available currently.

The lights are held together with several screws, my Wera Hex Plus 1.5mm keys were able to unscrew them, and there was no thread locker that I could find. The rear specifically says “Do not disassemble” but I had to at least take a peak inside. What I found was a pair of what I assume are 14500 batteries in a pack, labeled as 2000mAh, 3.7v.. I couldn’t fully remove the battery pack so it must be attached to wires inside to the switch and charging port circuitry. I’m guessing removing more of the screws would get this to a place you could actually replace the batteries if you wanted to, but it would be a somewhat complicated process and may involve a soldering iron. Most consumers are not going to do this, even most flashlight enthusiasts.

Edit: I did go ahead and remove some more screws and the battery has wires coming out from it that are soldered directly to the circuit board. Totally replaceable if you should choose to, you just have to work a bit and solder. 





The button section appears to be the same as what Wuben used on the X-0, it’s a hatch system that covers the button and the USB-C port cover. It’s an interesting design, and while it doesn’t offer much water protection for the port, the port itself is waterproof. I will note, that because of this design using lockout is a must as this large switch is easy to press when carried in a pocket or bag. The hinged lid for lack of a better word is magnetically attracted. There are 2 sprung silver-colored magnets that it rests on. There was definitely some engineering that went into this. 



My prototype didn’t come with any of the retention options that Wuben is promoting on the campaign page. It looks like it has a lanyard option that attaches at the rear on one side with a metal clasp. This lanyard looks like it doubles as an integrated USB-C charging cable too, which is neat. 


My light did ship with the large improved clip that’s on the rear of the light. This is a very large clip that takes up the entire rear of the light pretty much. I don’t see myself carrying this in my front pocket, due the size. You could in theory put it in your rear pants pocket (In lockout mode), but I think for many people this will be a light they put in a bag and this is what Wuben shows in their material. The clip works well to fit onto molle webbing, which you might have on a bag or vest. Unfortunately, the clip is facing the wrong direction to clip this on to the top of a hat, the lights a little heavy for that too IMHO. 


Size & Weight

I measured the light at 3.35” long, 0.80’ wide, and 1.55” thick. I measured it as 4.33oz with the clip installed. The light is IP68 water and dust rated. 


LED & Beam

There are two LED options for the Wuben X-2 Owl. There is the Osram P9 which produces a few more lumens and I believe is a cooler white and the Samsung LH351D emitter which is a more neutral white and high CRI. Each version has 3 of the same LED’s, in a linear setup, each with optics. I have the Samsung LH351D version, and on my Opple Meter I measured the CCT at 4468K, and 96Ra (CRI). DUV was right in the middle, with no green tinge which was nice. The beam here does have a profile that mimics the shape of the physical light at shorter distances, at longer distances it diffuses and is unnoticeable. There is PWM here in all the modes, it’s pretty fast and I can’t see it with my eyes or camera.


Night Shots

Night shots can be found on the video. 



Below are the outputs I got at the 30 second mark in terms of outputs and the percentages of claimed outputs with the Samsung LH351D emitter


  • Turbo – 1750 – Lumens – 97.2% of Claimed
  • High – 312 – Lumens – 78% of Claimed
  • Medium – 80 Lumens – 80% of Claimed
  • Low – 7 Lumens – 140% of Claimed (Take this with a grain of salt)

Wuben’s official Outputs.



Heat & Runtime

I did my testing with my Owl here that has the Samsung LH351D LED’s. I did this in the default output levels for each mode (they are adjustable). Turbo lasted about 90 seconds and after stepdown was about 600 lumens. This was then very consistent out to 1:17:00 when the light turned off. Max heat during this time was about 43C (Uncooled), at the 40-minute mark. 

I also did runtime comparisons with 3 modes, Turbo, High, and Medium. Turbos total runtime was 1:17:00, High was 2:50:00, and medium was out to just shy of 11 hours.



The interface seems to be the same as the X-1 Falcon, so here is what I had written up for that. My light arrived in Lockout mode, so 4 presses of the button unlock or lock the light. Single press to turn on, long press once on to cycle through the 4 main modes. Double press from anywhere to get to turbo. The light does have blinking modes that you can get to from anywhere by triple pressing. Triple press again to cycle between strobe and SOS modes.


The unique aspect of this light is the programming mode, It allows you to adjust the preset value of the 4 main modes by one on Clicking and holding and the light will ramp up slightly and blink when at the top of the range. Just stop when you reach the brightness you want and it will memorize it. There are upper and lower bounds on what each mode will do too. Consult your manual to see the exact ranges and directions.



As mentioned before there are two 1400 Liion batteries internally witht a total capacity of 2000mAh according to Wuben. These are non user replaceable. I did my recharging testing by first running the light untl it shut itself off. I then hooked it up to my tester and in this case used an Xtar 45W USB-C power source (With my own cable rated for 100W), and the light charged in 2:37:00. Max amperage during this time was right at 1A. The charge curve here I felt like was a tad harsh at the beginning, many lights tend to ease into it at the beginning while they are sensing the battery’s charge level, this did’t do that, just straight on with as much as it wanted. I did some subsequent testing and had no trouble charging via USB-C to C, or with chargers supporting USB-C PD. The light will work in Low, Medium, and High while charging. The light will still operate on low, medium and high while charging too.



The X-1 Falcon was a pretty large light, so making a smaller version is a logical step to take. The X-2 Owl I think will be a size that ends up being a better fit for people and a good combination of output with runtime. I’m not sure the switch version here makes a tons of sense, it make the use of lockout mandatory whenever the light is in a bag or pocket. While neat and different accidental activation is really easy if not using lockout modes. 

I like that Wuben is offering this in so many colors and materials from the beginning nearly. While I’m not a huge fan of established companies using Kickstarter, this does give them a good method to determine the demand for more specialty materials, or emitters. The LED choice here is good with the LH351D seeming to be the default choice for most lights, it’s a good neutral white, high CRI option. The beam profile is decent despite the emitters being in a line. Too bad here though that the batteries are not more easily replaced, it seems like that would be a fairly simple thing to do, even if you had to use a screwdriver to do it a few years down the road. So overall a solid option, if you want a form factor that’s a bit different or a flashlight that doesn’t look like your typical round light.

The Kickstarter campaign here runs through the end of November 2022, so if you are interested in looking more at it and picking one up check out the link below in the description on where you can find this one. It looks like they are expecting to ship these out pretty soon, in January of 2023, so you won’t have to wait very long.

Wowtac A6 Review (1460 Lumens, Super Small & affordable 18650 EDC Flashlight)

Wowtac has a new ultracompact 18560 EDC light on the market with the A6. The light is running an SST-40 emitter in either cool or neutral white (Maybe?), it comes with an 18650 battery and is microUSB rechargeable all for a very affordable price. Thanks to WowTac for sending this to me to review.

Packaging & Accessories

Packaging here is a basic Wowtac brown cardboard box, that’s shared with the A6 and A7 models. It notates what model and emitter are inside. Accessories included with the light are a WowTac branded button top 2600mAh 18650 battery, a microUSB cable, 2 extra orings, pocket clip, and a spare port cover. The manual is in English, German, Japanese and Chinese and in case you don’t know WowTac is supported by Thrunite and covered by a 2 year warranty.



As expected the light is made from aluminum and anodized black. Machining here is good. The tail cap is recessed slightly and allows for good tail standing and has an attachment point. Inside is a single spring and no magnet. 

The body tube and tail cap both feature some pretty aggressive knurling. While I like this in my hand, it will most definitely wear a spot in your pocket. The body tube is not reversible meaning the pocket clip is only mountable on the rear of the light. I would prefer a little deeper carry clip but this one is good and does an adequate job.

The head of the light features a semi translucent button with blue and red LED’s underneath. The blue LED comes on for the first few seconds when the light is in use and then when recharging the light will go red to indicate charging, blue to indicate charged. On the sides there is a little bit of milling for heat dissipation and style. On the rear there is a small silicone cover for the MicroUSB recharging port.


Size & Weight

I measured the overall length of the Wowtac A6 at 97mm, diameter at the head at 24mm, and diameter at the tail at 23mm. Weight with the included battery and clip was 96.1g. The water rating is IPX-8 rated which is good for this type of onboard charging port. 

This is a small light for an 18650 side eswitch. It’s the shortest side switch 18650 light I have that has onboard USB charging. The Emmisar D4 and BLF FW3A are both shorter but by very small amounts. The Olight S2R Baton II is just a little longer and slightly slimmer. It’s roughly the same lenght as a Reylight Lan or Pineapple but thicker due to the 18650 vs 14500 battery.

LED & Beam Pattern

This light is using a SST-40 LED and in my example is cool white. A neutral white version is listed on WowTac’s website and in the literature but the neutral white doesn’t seem to have ever been available in the past few months. Maybe it’s delayed significantly. The reflector here is unusually large and short, with a nice orange peel. The result is a beam profile with a decently large hot spot and a good amount of spill. I do notice some tint shift across the beam from the hot spot to spill unfortunately. Overall a very useful beam for EDC and general tasks in my opinion. Sorry for the beamshot tint here, it’s more blue and green then it should be, not sure what went on photography wise, ill have it sorted for my next review.


Heat & RunTime

For my runtime tests, I used the included Wowtac branded 2600mAh battery. This is an adequate battery for the price, but you can replace it with any quality 3500mAh if you want more runtime. Turbo on the Wowtac A6 will run for 1:30 before stepping down significantly. It went from 100% relative output to roughly 28%. 1460 lumens to 400 according to the manufacture. The light then ran slowly declining to about 20% relative output for 170 minutes. The last 100 minutes or so were a slow fade and then it ran in low then firefly for a total runtime of 260 minutes. 

Heat was well controlled during my runtime tests, and the hottest I saw the light get was 93F within the first minute. 


Listed output modes are:

  • Firefly – 0.5 lumens
  • Low – 12 lumens
  • Medium – 80 lumens
  • High – 400 lumens
  • Turbo – 1460 lumens
  • Strobe – 350 lumens

Mode spacing is ok, other then turbo sticks out here quite a bit. I would be prefer high be a bit brighter and medium and be stepped up a little to compensate. 



The UI utilizes a single e-switch up on the head of the light. The button is small and would be hard to use with gloves. UI here is simple and shares from other Wowtac & Thrunite lights. From off, long press to go to firefly mode. A short click from off will get you in to normal mode with memory. The light starts in low and if you hold while on it will progress from low to medium and then to high. Double click to go to turbo. Double click from turbo to go to strobe. 



My scope does detect some PWM on this light in Low, Medium, and High, but my eyes don’t see it with my eye. 



The A6 has onboard recharging via microUSB. It’s disappointing that it’s not using USB-C as other lights in this price class like the Wurkkos FC11 uses USB-C. Anyways I charged the A6 from LVP at 2.757V to Full at 4.13V in 3 hours 14 minutes at a max of 1A. Constant speed out to just about the 2 hour mark before decreasing as the battery fills up. I tested the included battery capacity in my Xtar VC4s at 2389mAh out of the rated 2600mAh. 


  • Great Value & a complete kit
  • Choice of emitters maybe
  • Small size



  • Missed opportunity to add a magnet to the tail cap.
  • Neutral white is listed as an option but has never actually been available for purchase yet.
  • LVP kicked in and shut off the light at a fairly low 2.757V.
  • Huge drop in output between Turbo and High 1460 lumens vs 400 lumens



My conclusion is that the Wowtac A6 is a good, low price, high value 18650 based EDC style light. Due to it’s small size and pretty decent pocket clip it rides well in the pocket. The interface is intuitive and makes sense. The beam pattern makes sense here for EDC, it’s flody with a hotspot, I just wish it had less tint shift and that high was a little brighter, but this can hold its own. 

I can recommend this light but wish the Neutral white would come available soon. Hopefully we will see it sometime soon after Lunar New Year.
