Wuben X-0 Knight Review (EDC, LH351D, Kickstarter Preorder)

Wuben has a new EDC light they are currently offering via Kickstarter. It’s the X-0 Knight and it’s a twist on the right-angle light we typically think of in headlights but this time around more focused for EDC. It’s a modern design and a big chunky boi. Thanks to Wuben for sending this to me, if you are interested I will have a link to the Kickstarter preorder in the description below. The Kickstarter will be running through July 16th 2022.

Packaging & Accessories

This is a preproduction sample and really only came with a charging cable and spare orings. The clip and battery are preinstalled. The packaging and accessories will be different in the production version.


Construction & Design

The Wuben Knight is a twist on the right angle we more commonly see on headlamps. It has sharper, hard angles to it that to me are modern. They have 4 color options, the Black and white versions are made from aluminum with the black being normal hard anodized and the white being what they call Micro Arc Oxidations which is what I have. I thought this was a Cerakote finish at first and it has a silver tint to it. The other dark gray and Green are both made from titanium. The green is my favorite because it has a circuit board pattern anodized into it. 

The top has an operating and battery status indicator as well as a metal cover that acts as the USB-C port cover and the switch pad. 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. The hinged lid for lack of a better word is magnetically attracted. There are 2 sprung brass-colored magnets that it rests on. There was definitely some engineering that went into this. I will talk about the pocket clip in the retentions section and the lens in the LED section.

The body also features 4 milled slots and 2 on top, for 6mm x 1mm tritium slots if that’s your thing. At the bottom is the round magnetic cap. This is a strong magnet and has no trouble holding the light up. It does unscrew but they have chosen to make it a little difficult. I ended up using an adjustable jewelry wrench to get it open. Once unscrewed you can replace the 18350 battery inside.  



The W0 Knight is designed to be an EDC light and comes with a milled aluminum pocket clip preinstalled. It was quite close to the body and retention was good, however, I bent it pretty easily pulling it out of my pocket one day. It’s just slight and something I could probably fix if I removed the Torx screws and rebent it. It’s a reasonably deep clip but still kind of a chunky carry in the pocket due to the diameter here. The tail is magnetic here as well. There are milling marks in the clip, not sure if those will be tumbled out in production or not.

Using lockout is an absolute must if you’re going to EDC this in the pocket. When carried the lens is facing your pants, and it’s very easy to turn on with the large loose paddle over the switch. This will burn holes in people’s shorts and pants if you’re not careful. You can lock and unlock with 4 quick clicks. 


Size & Weight

I measured the length at 57mm, width at 33mm (From clip to lens), and depth at 24mm. I measured the weight at 2.94oz with clip and battery. The light is IP68 water rated. Important here to say that it’s the port itself is water-rated due to the construction. Here are a few comparisons with lights that I have that are most similar. 


LED & Beam

The Wuben X-0 Knight has 2 LED options, an Osram P9 LED, and a Samsung LH351D which I believe I have. I tested the light with my Opple meter saw 4950k tint with a CRI of 96. It’s a pleasant neutral white and the TIR optic is good for EDC tasks because you get that hot spot for a bit of throw, but also get a significant amount of flood while in a compact package. Mode Spacing here is reasonable from the moon at 1 lumen, to high at 250. However, Turbo is a huge jump up to 900 lumens. To the eye, it’s not as big as it seems but it’s still big. There was no PWM detected.


Output Measurements

Heat & Runtime

Turbo on the LH351D was good for right about 50 seconds before it reached it’s normal output around a measured 200 lumens. This lasted out to 2:15:00 which isn’t too bad for a 1100mAh battery. I did another runtime test comparing Turbo, to High, and Medium. Runtimes are expected with less bright modes being more efficient. The heat peaked around 35C which is just above body temperature so comfortable to hold in the hand.



Default UI is pretty similar to many other flashlights. From off a quick press turns the light on in the last mode used, and then long-pressing causes the light to cycle in from moon to low to med to high. Double press to go to turbo. Direct to low can be accessed by long pressing when off. To get to strobe just double click when the light is off or on turbo. 

There is also a programable mode where you can slightly adjust the outputs of each mode, however, the manual only told about this and not actually how to do this. I presume they will fix this before the Kickstarters ship.

Locking is critical in this light and is easy to use, click four times quickly from off to lock and again do this to unlock.



Recharging is done via the USB-C port on the top. It’s a semi-exposed port but has been waterproofed although debris could be a problem. The total charging time of the 1100mAh 18350 battery was 1:33:00 with a total charging rate right at 1A.

I will note here again that the battery is removable but tools are required to do so. I used a watch wrench but I think a pair of snap ring pliers would work but your chance of scratching would be much higher. It would be nice if Wuben included a simple tool here to help, or changed the milling in the bottom of the light so that you could use a coin. 


Final Thoughts

The Wuben X-0 Knight is advertised primarily as an EDC light. While most people think of right-angle lights more as headlamps they work pretty well as EDC too. For me this is probably a little bulkier than I want to carry with shorts on due to its diameter at least with shorts on. 


That said I think this is a unique design. I like the exterior look myself, and I like it’s being offered from the beginning with different colors and materials. It’s great they are offering it a neutral white and what appears to be a high CRI LED. I will again remind you if you pocket carry this please use lockout (4 fast clicks) or you have a strong risk of melted pockets)

I do think it would be great to see a small headstrap included so you could use it as a headlamp if you wanted. I do think some type of wrench should be included to help open the tail cap to change the battery out, otherwise, you really need a tool here to help you. 

One small note here is this is being offered as a Kickstarter preorder. Call me old-fashioned but I still think of Kickstarter as a way for small companies to get funding to turn around and make their first product. Wuben is a midsized flashlight manufacturer, well established for many years now. They don’t exactly fit the mold for a startup company, but they are not alone in using Kickstarter as a marketing platform. It seems to be the standard these days. The project has exceeded it’s funding goal so the risk of not getting your light should be minimal.

So some interesting design choices on this one make the exterior kind of unique but the inside seems to be a pretty solid EDC offering if the diameter isn’t an issue for you. Let me know what you think of it in the comments below.
