Hello everyone,
Important update [10/23/2020]:
Sofirn informed me they will work on a new AA flashlight design, replacing the SP10S design. Consequently, SP10R will be shifted onto the new AA schedule. Due to larger scale launches of other new models, SP10R will need to be postponed until further notice. Please stay tuned for any future updates.
Since Sofirn's C01R received a lot of great feedback and interest, maybe it's time for the next step and release another iteration of Sofirn's successful SP10 series, now using deep red light. I call it SP10R to follow the naming convention of its prececessors SP10A, SP10B, SP10 V2.0 and SP10S. Sofirn was able to get a bunch of Luminus SST20-DR (660nm) which are fortunately not as difficult to source as Nichia's E21A, reasonable in pricing and great in performance. For those of you who have not come into contact with photo red / deep red light, you are highly encouraged to check out Sofirn's C01R using XP-E2 photo red which is on sale already.
Here's the datasheet to Luminus's SST20-DR: https://download.luminus.com/datasheets/PDS-003040-Rev-04-SST-20-DR.pdf
A review of SP10S can be found here, if you are interested in the general look of the SP10S host design: https://budgetlightforum.com/t/-/60177
Sofirn SP10R
For reference only - a sample picture of SP10S, a predecessor using a white LH351D LED but similar in shape and size.
Typical applications:
- Low-light usage to maintain night vision capability
- Finding keys, stargazing, astrophotography...
- Military/outdoor use (reading maps, orientate without attracting attention, no attraction of insects)
- Ambient colorful illumination (nightstand, decoration)
Typical light color (taken from C01R using XP-E2 photo red):

Since this plan may eventually lead into an actual sales/groupbuy thread, I have decided to put this in the commercial sellers / BLF user negotiated deals subforum.
