Factory and warehouse is trying best to fulfill your orders as soon as possible, your patience is much appreciated.
Search Amazon 3M Scotch-Brite 6×9” sheets. They come Red/Coarse Green/Medium White/Fine grit…
The abrasive pads are primarily used for auto body work, sanding irregular surface contours without worry of taking off too much material on sharp edges
Also used in metal working polishing, deburring, or “shoe shining” shafts on a lathe
For buffing off LEDs (diffuser) I’d try medium grit, or coarse if not effective
Cheers!
Thanks Kona, your help is much appreciated 
Before I used fine water sandpaper grit 600~800 for similar works

Ok, so the new C01 is even less bright than the Yuji 3200K C01? Is the runtime at least longer then?
It must be a bit brighter than the Yuji led, see the chart below that I made a while ago, but we are still talking a few lumen from a 5mm led, so do not expect too much.
Ok, a bit brighter would be perfect. A bit less than E01 is wonderful
/EDIT: ordered 5 in 3400K :-).
Picked up a total of 19 of these C01 (including 4 of the red version) on behalf of my own collection, for a couple of friends, and for Christmas gifts. Not sure if this iteration of C01 had an interest list, but I’m fairly sure I expressed interest earlier in the thread, so I wanted to give support and confirm that a purchase was made.
Really appreciate Sofirn being active here on BLF and making product decisions based upon our feedback. Can’t wait to receive them!
Received shipping notice… However, when I click on tracking get a blank page. This has been the situation for over a week now.
Does this mean my lights are being shipped by very slow Chinese Junk?
Have you tried entering the tracking number on a tracking site, like https://www.17track.net?
It’s possible their site just glitched out.
Thanks Serlite, Yes, that site works great!
Shipping much faster than slow sailboats. Arrived at West Coast distribution center today 
I also use this site for tracking and it provides some information that 17track doesn’t show:
To USA buyers, when track on 17track.net, you need to change the carrier to “DHL ecommerce US”, while the default is USPS which give only a receving information.
Does you shown YANWEN Logistics on tracking info?
I have to ask, does the C01 5mm “Sophia” Led version come with no glass lens?
Mine arrived today and works great, but I was wondering about the lack of a lens and an unpolished Alu “reflector” that you can touch because… no glass!
That’s the way they are conceived.
The C01S has an SST-20 “power”-led and a TIR optic.
The C01 has a 5mm led, sticking out of a “cone”.
Parts of the two heads are not interchangeable.
LOL Yup, that about describes it perfectly! 
Around the base of the 5mm led, in a groove, is a o-ring to waterproof the interior of the head.
you`re making me want to take it apart now!
I did actually wonder if it had any sort of IPX rating or at least dust resistance for EDC use.
Maybe Djozz’s son can do another penetration test on the playground again? According to the first test C01 seems to sustain even toughest abuse. :smiling_imp:
