I have received the Wuben I331 from Tmart.com (link is external) for the review, curtesy of Ray.
They gave me a coupon for the I331: Wuben

I make my best efforts in order to be as impersonal as possible in the early parts of the review, limiting my personal comments at the end of the review. However, I am being nothing but honest saying that I am really surprised by the packaging.
I have seen some lights during the years of flashlight passion, and I don’t recall a package like this. The box looks like a sci-fi book, ready to sent you into space. I usually don’t care much about the packaging and I open it right away to check the insides.
With this box I spent a bit more looking at this black package with shiny grey lettering and geometrical pattern.
Let’s open the box, shall we?
Inside you have: the I331, a 14500 battery branded Wuben, lanyard, and braided micro USB cable.
I don’t want to sound like a broken record, but I have not seen many lights looking like this one: the black HA III anodization is interrupted by geometrical milling with a shiny finish.
The XP-L V5 emitter in a smooth reflector, with a crenelated metallic bezel on top. The emitter is slightly decentered, and at the bottom of the reflector there are some imperfection. A residue of the machining?
The U shaped tailcap allows tailstand and easy access to the mechanical switch.
At the head an electronical switch
Unlubed but well made trapezoidal threads. They are anodized so you can physically lockout the light untwisting the tailcap.
The light has a micro USB port for charging the batteries. The micro USB cover has some protrusion to keep it in place.
It is a very big light for an AA light. It could easily pass for a 18650 light.
Using the tailcap switch you turn the light on and off.
With each press of the electronic head switch you will cycle between the levels, in a descending order (high, medium2, medium1, low, moonlight, high… in loop).
When the light is on keep pressed the side switch to go directly into high mode.
When the light is on a double press of the side switch will get you into strobe mode, and another double press will give SOS mode.
The side switch has a led underneath it, it is blue flashing when the battery is above 30% of charge, red when the 10%<charge<30%, and flashing red when <10%.
When charging using the micro USB port, remember to click the tailcap switch as you want to turn the light on.
Output and runtime
Output and runtime have been tested with the provided wuben 14500 battery.
First I test the 600 mAh battery at 1.5A up to 2.8 volts with my SCYRC MC3000.

The light is well built, and the packaging is really super nice.
However, the light should be improved to be on the level of the packaging: the reflector on my sample has some imperfections, there is visible PWM at all levels but high, and the regulation can be improved on all the tested levels.
Thanks to AntoLed for lending me the camera and the luxmeter.
