“… the TIRE to has a round spot” What does this mean?
The spill with the previous TIR has a square shape... more like 3 corners and a rounded 4th. The spot is round and nice. I should take a picture...
I have a new one inbound for Monday.
Still confused on that comment.
I have a C3 bought about 6 weeks back. Guessing it’s got this over-charge “feature” 
I do like the light though (despite the 2600mAh “protected” battery- wass’up with that?). Still a nice throw for it’s small form factor. I’ll just charge via the Zanflare Vs. the internal USB port anyway. Also prolly’ use a Q30 or something a bit more modern battery wise.
I would be too. I posted a picture above so the outer and inner spot IS round and it's just that outer TIR artifact, aka. spill, I think, what some commenters find detracting.
I just pulled mine out and see the “square bottomed” spill as your pic shows… looks like a “flat tire”
— thanks for that effort Nach!
Sorry to make your confused.
The first stocks of C3 has a square spot. But our tech guys has solve this issue by upgrade the TIRE to make the spot round rather than square.
Check Nachtfeuerzeug comment on #19 for more info
OK, I sent an email just now. Are you suggesting I can get a replacement? I own a C5 too (great little light!)
Thanks.
That depends on which verdor you bought from.
This is the shop I charge: https://amzn.to/38EnK7G
Anyoe has bought the first batch C3 from the above link, pls PM me your order number for after- service
Hey great service here! I DID buy from that Amazon shop and am sending you my order # right now!
Thanks Wuben!

Perhaps TIR was meant?
Olights i1r2 does the same square spill. I thought that would indicate a good alignment of LED and optics.
Just a shout out here to Wuben for standing behind the MANY great lights they sell. :+1: :+1: :+1:
I personally own a C3 (and smaller C5- 14500) bought this last year. BOTH nicely designed lights with excellent finishes (several colors). The C3 had issues with overcharging (see this post a few months back). It also had a slight misalignment problem with the reflector/led. As I bought the light on Black Friday I figured I (kinda) got what I paid for, BUT when I asked them about it they INSISTED on replacing my C3.
In fact, SEVERAL Wuben reps contacted me to insure I was happy. Very professional, honest, and straight-up about the C3 problem and wanting to make it right.
I was a fan, and now I’m a BIG fan of Wuben… and I can see more of their lights in my future.
I got the Wuben C3 from Banggood before (which has the overcharging issue, which I am more concerned about).
I also did notice the "flat-tire" beamshot when shining the C3 on a wall, but I think not too noticeable in actual use..
In my Youtube beamshot video below, I made this comment in the description, about the "square-shaped" beam pattern for the Wuben C3:
I'll try to make another beamshot of the new Wuben C3, IF I can be assured of getting the new version (I am unable to order from Amazon).
Nice to see your comparison beam shots d_t_a!
I had a delivery of the corrected design C3 get screwed up by a new postal worker who couldn't find the mail box so hopefully, I can get some beam shots by tomorrow.
The new light arrived early today. The protected Wuben battery was at 3.6V when I started the cycle and terminated at 3.9V.
Concerning current draw, measurement was 3.1A & >4A with a 25R.
At ~4V on Wuben battery, I measured 1200 lumens.
With the Samsung 25R, it produced >1500 lumens.
And finally, the new TIR beam pattern is round. Both the spill and the hot spot.
I haven't found a single LED, clear, tight beam TIR without optical artifacts but this new one is good.
I'm charging one of the unprotected Samsungs I used in the previous post, at the moment, and will report on that.
My meter was still showing a 0.008mA current but the battery charged up to 4.16V.
Got my replacement and can confirm everything Nachtfeuerzeug said.
My voltage ending was 4.17 , my USB tester only goes out to .00 and it was at .01 when I pulled it.
As far as beam, she is nice and at least on my sample it is a tad warmer looking.
Mode memory also works well.
She’s a beast for the $.
Thanks to Wuben for making this right.
Later,
Keith
Picked up one, used discount on amazon, $20.00. Charges correctly, bright with round beam.
