Thanks a lot for your great support and confidence. I will keep on trying to find another manufacturer who may be able to develop something similar. Maybe even Hank Wang might be interested, who knows. I will ask him. ;-)
I do not know about Sofirn's further plans regarding C01S. I suggested them to use the 3 mode UI for C01S as well. I can only guess but the odds look good they will eventually use this UI on C01S, too. Same applies for any other tint/color.
Someone mentioned some days ago that Hank is not interested in making AAA/AA sized/compatible flashlights.
I think if we get the C01S hosts without LED and a reel of nice LEDs we could reflow it ourselves (or a few of us with shipping to other members). With all the work and additional shipping it might cost a bit more.
I hope so too. And soon. 
That needs a different MCPCB, too, as the footprint of the E21A is completely different.
If Sofirn or others manufacture can made small MCPCB for E21A I’m interest to get some
Interested
The project is suspended, most likely indefinitely. Sorry.
I think virence.com is intending to restock their version at some point, but the timing was unclear even before the pandemic, and that appears to disrupted all of Clemence’s plans.
What about virence, he has access to E21A and custom MCPCBs
Yes,wish project will be resumed
