Sorry, this thread is not about this (certainly wanted) variant of the C01S. If you are interested in the C01R (XP-E2 red or XP-E2 deep red), please let me know. :-)
Later on (after 11/11/2019 sales), I will be glad to run another multiple-choice interest check for more versions of the C01S, e.g. LH351D 2.700K 90CRI, SST-20 2.700K 95CRI or Osram KW CSLNM1.TG ("White Flat 1mm²").
Maybe Sofirn will consider using other optics in the future too. Like the honeycomb optic a user posted about earlier in this thread. Some floody versions of the C01S would be awesome!
Yes, I think so, too. But if Manker can do it with their EC05 or Acebeam with their M50, well....I'm confident Sofirn could make it happen, too. Personally, I don't like Acebeam's proprietary/rare battery in the M50 and Manker's EC05 is probably a bit too large for a tiny keychain light. So, a C01S using a standard AAA cell could be the ideal host. But again, this will follow soon in a separate thread (after I have talked to Sofirn about the feasibility and the future of C01S in general).
