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 (project name)

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 red (625nm) confirmed

or Cree XP-E2 deep red (660nm) 20 sample LEDs arrived - testing in progress

or Cree XP-G3 deep red (660nm) not available to order from Sofirn's suppliers

Lumens output:

yet to be assessed, monochromatic light is difficult to measure

User Interface:

• original intent: 2 modes, low - high, always start on low (like BLF edition)
  
• alternative: 3 modes with 2 modegroups: moonlight - low - high and high - low - moonlight

Body color:

• standard red or black anodization (deep red anodization not possible according to Sofirn)
• alternatives: maybe "no anodization" (silver appearance) if highly demanded (like C01S BLF edition) or new LT1 colors (e.g. dark green, desert tan, orange)

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

Please express your interest below with your desired quantity. At the moment, I will count any tint to gather a general lot size.

Thank you!
