Wuben T101 Review (XHP70,2x18650,3480Lm)+Outdoor beamshots

This is my second review on a flashlight provided by Wubenlight for test and review.

The current review is on the biggest flashlight in their product line,the T101.
It is a 3480 lumens flashlight powered by two 18650 batteries.
The powerful beam is entrusted to a large multi-die Cree XHP70 LED.
Wuben T101 can be operated by the tail switch for On/Off and mode changing by an electronic side switch.
The model is also equipped with a built-in charging electronics.
Read the review below for more information,my thoughts,runtime measurements and outdoor beamshots.

Weight comparison with other similar form flashlights.
Wuben T101= 462gr.
Fenix TK47= 475gr.
Olight M3XSUT= 367gr.
ThruNite Catapult V5= 652gr.
Nitecore TM16= 696gr.(not on the picture)

In size Wuben T101 is not much different than the other similar 2x18650 flashlights.
It has a cleaner design,as the head looks very well with all the needed cooling fins,stainless steel bezel and large,square button with the W letter.
The battery tube lacks any specific knurling or grooves.
Black matte anodizing.

Pictures from the included instruction sheet.

Wuben T101 comes in a nice hard case with metal frame and insulating foam inside.

Inside the case.
A wall charger with EU and US plug is included. Output 5V,2A.
Connecting the flashlight is possible with the included USB C cable.

Two spare O-rings and instruction sheet are also included.
The hard plastic case with metal frame is a good way to carry and store the flashlight with all of the needed accessories.
There is a place for spare batteries as well.

Wuben T101 comes with two Wuben 18650 IMR batteries with capacity of 2600mAh.
There is no any marking but the batteries seem to have a protection circuit,which is a good idea knowing the T101 can charge the batteries inside the body,connected in series.
adding these batteries to the set is a great option for new users and even for me,as this saves us the higher care with finding correct high discharge batteries with protection circuit.

In my medium size hand. There is no much anti-slip grooves(no knurling),but I did not find it a problem with this large flashlight.
The only thing that bothers me a little is that the reflector is very deep and the most of the heat goes to the cooling fins at the sides of the switch.
I can easily notice the heat while using the T101 on Turbo mode. The cooling fins positioned closer to the bezel get much less of the heat.
To sum up,it is getting hot around the switch,while working on Turbo mode.

The side switch is big and comfortable.It is designed to fit any size fingers.
It is relatively easy to find in the dark by touch,especially compared to other flashlights,for example Fenix TK47 is taking me a lot of time,as well as the Olight M3XSUT.

The switch cover is made of silicone,but feels reasonably hard on pressing.
It is easy to know when it is pressed and has a soft click sound when pressing it.
The W letter is illuminated only when the flashlight is connected for charging.
Red color when charging,blue color when charged.

The overall anodizing on my sample is very good with very few imperfections.
The front cooling fins are precisely machined with well rounded edges.
The cooling fins around the switch are a little different and with no edge smoothing.

User Interface

Wuben T101 has a forward clicky tail switch responsible for the On/Off operation.
Momentary On is possible-great for signaling.
Turbo-High-Mid-Low-Moonlight modes and hidden Strobe and SOS can be activated by the electronic side switch.
Just click the switch to change the current mode.
Fast double click activates Strobe mode.Another fast two clicks while in Turbo mode activate SOS.

All modes except Strobe and SOS are instantly stored in the memory for the next time when you turn the light ON.
The mode memory works flawlessly on my sample.No waiting as it is in the cheaper flashlights.

There is also a shortcut to momentary Turbo mode-press and hold the side switch for a second from any of the other modes.
Releasing the switch will return the mode you were on previously.

My only recommendation could be about the mode sequence.Turbo mode comes after Moonlight,which may be harsh to the eyes.
In my opinion it is better to go from Turbo to Moonlight-Low-Mid-High-Turbo.

Soft silicone cover for the charging port. I had no problems with it,so far.
It is on the opposite side of the mode switch.

USB C charging port with a good sealing cover.

The glass lens on my sample is impressively clean with great(high quality) anti-reflective coating which makes the glass to look like it is not there.
The aluminum reflector is also clean. I can spot some micro dust on the LED,though.

55 mm reflector diameter and about as much depth.

Macro look of the LED.The centering ring seems on its place,but the LED itself is not soldered precisely on its heat-sinking board.
It is worth to note it,but I don't think this is affecting the beam that much with a heavily textured reflector like the one used in this model.

Macro of the texture.

Square cut threads.Anodized on the battery tube and the tail cap.
For some reason my T101 sample lacks anodizing on a few places of the threads(visible on the picture below).
Interesting is the treatment of both springs-in the tailcap and the head.
Their end is pressed and filed to get a wider contact surface resulting in better contact with the battery and easier current flow.

Clean of knurling tailcap. Noticeable is the specific for all Wuben flashlights similar to infinite W channel.
The cap allows tail-standing,but as you may expect from a long heavy flashlight,it is stable only on a flat hard surface and any vibrating may bring it down.

The flashlight is long and pressing the tail switch requires to hold the flashlight at its end.
One hand holding it takes a good effort. I would prefer a nice protruded switch instead of the tail-stand/lanyard ears.

Runtime measurements

Wuben T101 was tested on Turbo and High mode.Batteries charged in an external charger for more equal voltage.
The two batteries are connected in series. It is recommended to use batteries charged to the same voltage.
This will allow a little longer runtime.

Lumen measurements:
(with non professionally calibrated integrating sphere)

Turbo mode= 3350 lumens
High mode= 1240 lumens
Mid mode= 440 lumens
Low mode= 92 lumens
Moonlight mode= 13 lumens

3420 lumens maximum initial brightness measured in the Turbo test.
(3480 lumens stated in the instruction sheet)

The T101 is programmed to decrease its output after 2,5 minutes on Turbo mode.
In my experience the head could get hot after a minute with output of more than 3000 lumens,especially in warm ambient temperature.
This step down is a good prevention of damaging the driver.It is uncomfortable to hold a hot metal,as well.
According to the instruction sheet,Wuben T101 features advanced temperature regulation technology.
I did not managed to activate it in my test or at least not what I expect. It needs more tests to confirm how the ATR implemented here actually works.

The output after step down is about 1900 lumens which is still quite a good output for most uses.
There was a second small 200 lumen step down 24 minutes after the first step down,in my test.
The output after step down is well regulated,constant.
When the batteries are almost empty,the output starts to decrease slowly until the Low voltage protection in the flashlight kicks in.
The LVP in the batteries was not triggered after the three tests I run to take the graphs.
About 2,8V resting voltage in each of the batteries.

The driver has also a Low voltage warning function.
When the voltage of the batteries is low,the light will flash a few times every five minutes.
These flashes are the vertical lines in my graph(some of the flashes were not recorded).

Current draw on Turbo mode is high,about 4,5A.

I am not very excited to charge batteries in series,but still this is a good option to have when traveling,or in the woods.
The charging circuit works on 5V input voltage as the included charger is designed for 2A load.
This means a powerful source is needed to get the best from the charging electronics.The voltage should be boosted from 5V to 8,4V which confirms the requirement for high current power source.
I did two tests-with a 1A wall charger and 2A wall charger. The current draw from the first charge was just 270mA.The charging time in this case will be very long.
With the second charger the flashlight was able to get up to 870mA which should allow a pretty good charging current.

Strobe frequency 8,7 Hz. Very well working-unpleasant to the eyes. I even had the need to use it against a barking wild dog,while taking the outdoor beamshots.
The constant light did not fear it at all,while the Strobe discouraged it quickly.

The driver in Wuben T101 controls the light without PWM. I can only see some kind of noise in the Moonlight signal,which I can not explain,but I don't see it in real world use,even looking at a cooling fan.

Beam profile

The Cree XHP70 LED in Wuben T101 produces cool white light,slightly warmer than the Nitecore TM03(with XHP70) and Nitecore TM16,which I used for beam comparison.
I don't see distracting greenish or bluish tint.
As you will see later in the beamshots though,the stainless steel bezel reflects some light and projects it divided in different colors at the periphery of the spill.
I did not noticed it while taking the outdoor beamshots,however we can clearly see it on the pictures.
Most of the new flashlights come with a matte bezel,which solves this kind of problems.

The T101's beam is pretty well centered in the hotspot as thanks to the large LED and textured reflector,there is very useful bright spill.
This is one of my favorite beams-it just do the job properly. This is not a beam just to play with.
My only criticism regarding the beam is in the hotspot.Even the textured reflector,there is a darker zone in the center which is visible when pointing it at a building or other flat surface on a distance.
You can see it on the wall beamshots below taken at 1/50sec and 1/250sec.

As I already commented,while taking the beamshots,looking at distance I did not noticed the color rings at the outer end of the Wuben's beam.
Now on the recorded picture I see the rings very clearly. It needs more testing on various environment,but I could say that the rings were not a problem for me.
I tried the flashlight also on a large building and my impressions are mostly positive. What a little confuses me is the darker zone in the hotspot center.
All of the flashlights that I have tested with MT-G2 and XHP70,XHP50 have it,so the situation here is nothing new.
If you use the T101 outdoor as I did in these beamshots,you will not notice the beam inconsistency.
And remember that I am seeking perfect beam quality,so I comment/criticize any imperfection.

In terms of color temperature/reproduction the XHP70 in Wuben t101 is definitely better than the TM03 and TM16.
The LEDs in the Fenix and ThruNite are neutral white and their light is warmer.
Overall,I liked the T101's beam and found it very useful for real world use,even on a very long distance.

Thanks for reading and looking at the variety of pictures!

Thanks to Wuben for providing their great new models for test and review,so there will be more helpful info about them on the net!

Nice review! I wonder when manufacturers will start heading towards XHP70.2 and smooth reflectors?

Thanks for the comment djburkes!

Thanks for the thorough review FlashLion! Looks like a very nice flashlight. I like the USB-C charger and the filing of the spring(s) for better battery contact. Nice touches.

USB C does not need any orientation. It goes in both ways! Thanks for the review

Haha,thanks for the correction! This is why the feedback is important. I was looking at the flashlight,which looks different on both sides,but did not look more precisely at the cable.
This explains the marking lack. :FACEPALM: Will correct it before I mislead someone else.
I would prefer to use the microUSB cable from my tablet with its 2A charger,though.

Glad to rectify! But nowadays new electronics are going with the USB C as the current can go both ways
