Wuben kindly sent the E7 for review.
There’s an optional headband, optional sensor for handsfree operation, and an optional 18650 extension tube.
It’s a bit like the Wuben X0 but there are some big differences.
Here is my review:
1 Thank
Great review, thank you for sharing.
I do have a question for you. Are the two optics individual pieces are all in one? Also, how tall are they? They seem to be very flat/thin.
Thanks

The optic is one big piece. I’ll measure it tonight.

Of the similar headlamps you have tested would you recommend this ot another for garage work? It looks really nice from that review but it has so short runtime that I would be using it with a 18650 extension so thst brings size up to all the other headlamps
Armytek Wizard C2 Pro Nichia is pretty good. Floody nice beam. Strong magnet. Excellent regulated output.
I haven’t done a full review of this Nichia model but I prefer it over the WR due to the floodier beam.
The TIR optic is 3.76mm thick. The two feet extend the thickness to 4.56mm.
16.25mm * 31.24mm * (3.76mm to 4.56mm).
Height * Length * Thickness.
Thank you!
I am impressed as to how incredibly shallow the optic is compared to your typical reflector or TIR.
Are there any artifacts or tint shift in the beam?
2 Thanks
No noticeable tint shift with these cool white emitters.
There are artifacts like the X3 but the two emitters cancel it out.
With the X3 there’s a square pattern in the middle due to the shallow optic and due to having one white and one red emitter.
The E7 has two white emitters so the spill of each overlaps the square pattern and this results in a smooth oval shaped beam.

Thanks again for all of the great info. Does the X0 have any artifacts or tint shift?
1 Thank
The X0 doesn’t really have any artifacts or tint shift. The reflector is a bit bigger. It is throwier but the beam is smooth.

If you have a Wuben E7, DO NOT insert an unprotected cell in reverse!
An unprotected cell may be shorted if a battery is inserted in reverse. This will damage the driver and it could cause a fire.
The included protected 18350 cell works as expected and did not get warm or damage the driver.
I inserted an unprotected 18650 cell in reverse, screwed the tailcap on, and the torch started to smoke! The driver has been burnt and no longer works.
The Wuben E7 should be recalled
While reviewing the Wuben E7, I noticed the tailcap spark when I tried to put the tailcap on with an 18350 cell inserted in reverse but nothing else happened. I asked a few community members and they weren’t able to reproduce this issue.
Wuben sent a second Wuben E7 (neutral white). This time I tried to insert an unprotected 18650 cell in reverse and the driver started smoking. The torch became warm to touch and it no longer works.

Wuben recommends using a protected 18350 or 18650 cell.
Wow, this seems like a big oversight. I know it’s not a huge deal to use protected cells, but its hard to imagine a modern light without reverse voltage protection.

At this stage of the game, 2024… no flashlight maker should be producing flashlights without polarity checks built in. Cell inserted incorrectly should simply refuse to work, protecting the circuitry and the cell. Really a shame on you, Wuben. You should know better!
