I would get at least three of the 3400K and three of the 670nm red.
One question, on the driver, could there be a resistor that is user replaceable for different power levels? The stock one is 20ma, then if you replace the resistor with one that has less resistance it could be set to 40ma or 60ma. Would still give 5+ hours at 60ma and that looks to be around 17lumen, which is a nice amount of light for 5+ hours out of an AAA.
Just my opinion, but around 1 lumen should be fine. I have a red LED Peak Eiger that I’m told is 5 lumens and honestly, it seems too bright. I used to have a Streamlight Stylus (the original 5mm LED 3 AAAA) with a red LED and that was perfect, but I have no idea how bright that was.
Thank you for your willingness to alter the output of this version, we all appreciate your flexibility.
I’d like to hear more opinions on the output of the red version.
For those who do not have a C01R and C01S, maybe these photos can help visualize what 0.5, 3, and 5 lumens might look like
Standing up, I cannot see something on the floor, or walk, with 0.5 lumens red
I can see something on the floor, and see well enough to walk, with 3 lumens sst-20 and 5 lumens red
that is why I suggest for the single mode light, to have 5 lumens, not 0.5.
Not sure if Sofirn will do that, but I was thinking about the colours used in the C01S, such as orange, olive green, desert tan!
Hum…nah, it would defeat the purpose of this light (for me)!
Too much hassle already to bring these C01 wwith Yuji leds back to life again (thanks Sofirn for it!!!), so fancying other things…not my league for such light!
