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

Pre-Order now for only $ 7.99:

https://sofirnlight.com/c01s-aaa-flashlight-starts-on-low-p0118.html

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 but not used in actual production (deep red will be prioritized)

or Cree XP-E2 deep/photo red (660nm) confirmed

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

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: http://budgetlightforum.com/node/69811

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)

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.

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!
