Hello everyone,
The project of a Sofirn 14500/AA light with red LED has been suspended for technical limitations (see here). After discussing some alternatives, I would like to present you a more feasible concept that Sofirn is highly interested in - a AAA keychain light using the widely known and appreciated Sofirn C01S host and driver design and a small yet powerful red LED for red light illumination.
Sofirn C01R
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)
Specifications (as in C01S):
Emitter:
Cree XP-E2 deep/photo red (660nm)
as of 10/2020: Luminus SST20-DR deep red (660-670nm)
or Cree XP-G3 deep red (660nm) not available to order from Sofirn's suppliers
Cree XP-E2 red (625nm) confirmed but not used in actual production (deep red will be prioritized)

Lumens output:
yet to be assessed, monochromatic light is difficult to measure
low mode will be a sublumen mode (0.5lm)
User Interface:
- original intent: 2 modes, low - high, always start on low (like BLF edition)
- final version: 3 modes with 2 modegroups: moonlight - low - high and high - low - moonlight
[Poll closed!] please choose your desired UI by voting here: https://budgetlightforum.com/t/-/72855
Result of the poll (166 votes):
36% or 60 people voted for Low-High
2% or 4 people voted for High-Low
62% or 102 people voted for Moonlight - Low - High and High - Low - Moonlight
Sofirn is now introducing two mode groups with reversible mode order as desired
Body color:
- standard red as in C01S (alternative colors are not an option at this point of time)
- wine red or deep red are still yet to be discussed as an opportunity for a general new red anodization (not being pursued anymore)
- alternatives: maybe "no anodization" (silver appearance) if highly demanded (like C01S BLF edition) or new LT1 colors (e.g. dark green, desert tan, orange) (not being pursued anymore)
Voltage range: 0.9V - 1.5V
Dimensions: 71.6mm (length) x 14.5mm (head diameter)
Weight: 15 grams (without battery)
Battery options: 1x AAA 1.5V Alkaline battery or 1x AAA 1.2V NiMH rechargable battery
Price: should hopefully be in the same area as C01S with SST-20 4.000K 95CRI, i.e. around $ 9.00 - $ 11.00 if I recall correctly. Price may be a bit higher with a more sophisticated 3-mode/2-modegroup UI. Update 2020/05/24: Preorder price is $ 7.99.
Lot size: to be increased from 200pcs to 500pcs with regard to increasing demand. Update 2020/05/24: Lot size will be approx. 500 pcs.
Availability: yet to be confirmed, production will not commence before February 2020, i.e. earliest after CNY holidays.
Update: Ramp up delayed due to COVID-19 until mid of June, 2020.
Update 2: Shipping has started by July 2020.
Please express your interest below with your desired quantity. At the moment, I will count any tint to gather a general lot size.
Thanks a lot for your participation - everyone on the list below helped to make C01R come true!
