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).
If you are asking questions to Sofirn anyway, could you ask them (how dare I ask on BLF) to glue the bezel? They all come loose after some time so that when switching off the light at some point you suddenly have the bezel, lens and optic loose in your hands. And you can not screw the bezel too tight or the driver stops making contact with the battery.
