Wuben X1Pro - Picture Review with thermal and LUX measurements

Hello again!

Wuben asked me if I want to make a review for their new X1Pro flashlight if they send me one for free - so why not?
On paper, this light seems to be perfect for me. Somewhat big, bright and very floody. But is it as fitting as it seems?

The machining and fabrication over all is on a high standard. It feels nice in the hand and has no sharp edges at all.



THe pin for the battery hatch is more than enough for this job

The exit for the cooling fan, a bit blocked, yes, but in the end, it’s a flashlight that you hold in your hand and a big opening would feel worse, I think.
One solution for more airflow would probably be, to extend the cooling fins to the outer surface. But this side is not the problem…


This side is. It’s easy to see that any fan would have a hard time sucking air through these small openings.
In the Lux measurements we will see, that the cooling is sufficient, though.

Nice to have an important information like this etched into the paint!

The apartment where the fan lives rent free

This extra attachement doesn’t come with the light normally. Wuben sent this to me and I am happy about it, because I like to have 1/4" ports on floody lights when you need to have them light up a room or campsite without me having to handle it. It is also used to attach the light to a handlebar.


The USB port has a good and tigh cap

The lock for the battery compartment. This wasn’t working fully at the beginning, the little silvery piece wasn’t moving smooth. I had to force it into position a couple of times, now it moves as intended.

The light comes with batteries (XTAR VC4SL measured 4947/4892mAh). The light only accepts button top batteries!

The glass has an AR coating



Now let’s get inside!
The glass is quite thick and the gasket underneath is even thicker, very nice! No loctite on the threads.

The reflector is made from plastic, which surprised me because it is so well made that I thought it would be aluminum




If I looks at this picture, I think Wuben should have used a bit bigger wires for these 4 LEDs?

The underside of the flashlight head - If you want to use flat-top batteries, you could probably add a solder blob here? THe cable is for the balancing while charging.

This is the slot for the little fan, the color difference of the two parts is not that much visible in real, but you can see that the cooling-part has a tiny bit of a different surface texture than the rest of the light. I guess because the light has some sort of paint on it, but the heatsink is anodized.




The side switch comes loose, but there is not really something repairable underneath.




The only “flaw” of my light is, that the battery-compartment-hatch doesn’t open easy if there are no cells in the light. If there are cells inside, the hatch springs open.
On this picture you can see in the oval cutout where the lower arrow is pointing to, a little paint is missing because the latch is rubbing on the case.
Nothing you see if the hatch is closed and a really minor flaw that most people probably would never notice.

When I held it in my hand I was like “How do I use the two switches at the same time?” If you use the side button with your thumb (right handed), the slide switch is in your palm, out of reach.
So for me it is the most logical, to hold the light 180° “wrong”, click the side button with my index finger and use my thumb to switch modes. FOr my hand size, this light feels quite natural like this to hold.

A quick comparison to other square lights:
Wurkkos HD03, Wuben G5, WUben X4, Wuben X1pro, Yemao A200, Warsun X608


And with round lights that a lot of us have:
Emisar D4, COnvos S3, Wuben X1pro, Sofirn SC31pro, Wurkkos TS10

Now thermals in turbo, all LEDs on:
After a couple of seconds, fan not on.


After two minutes, fan kicks in after around 10 seconds:

After two more minutes, the temperature has settled at 60°C, so you don’t want to touch that heatsink.

Lux measurements from 1m distance:
Beginning: 30100 Lux
After settling the Lux hovered between 10500 and 11000 - even after 8 Minutes on turbo - very impressing!

If anyone wants to have this information:


DUV = 0.0045, a non-blue cool white

So, what do I think about this light?
It is not a cheap option, sure, but it offers a lot of light for a long time, and if that is what you need, this light might be one to consider.
The flood mode is really that, just a wall of light in front of you. There is somewhat of a hotspot, but at 1m distance, it is already around 70cm in diameter.
The spot mode is a medium thrower, nothing to search for something 500m away, but more like 50m away. At 1m distance, the spot is around 30cm in diameter.

Thanks for the review, especially for the little teardown! The plastic reflector is a surprise, although it makes sense with the difficult shape and the little rings. Also I didn’t expect hat the USB cover is the same part as the switch rubber.

Cool. I always wanted to see whats inside the X1 Pro. I reviewed it also and i think Wyben made changes from the pre sale model I reviewed. Good to know the LEDs can be swapped. It’s begging for a sft70 for the throw led and xhp50.3 HI for the flooders. Did you confirm if these are 6 volt leds?

Yes, they are 6V LEDs!

For the record, Fenix, Streamlight both use plastic reflectors (the LR80R has one). Way cheaper to make and they take a superior reflective coating for way better quality control and consistency. Not a bad thing at all!
