[Lux-Perpetua]

Fantastic news Barry!

One more thing, sofirn found a 670nm red led 5mm for C01 red body color.

Got some samples to test.

I would buy if they came with 2 modes UI reversible L-H and H-L

[Unheard]

Excellent

I’m in for the 670 nm C01 [and some C01 hosts ]

[Henk4U2]

I know this is not the proper thread, but I’m in for some hosts too.
(meaning host with driver, AKA light without a led)

[led_400]

Sounds great. I’m in for a 3400 and a 670nm as well.

@Barry0892

Finally sofirn got the 5mm led high CRI to replace yuji led.

Tint is 3400K

C01 with this new led will be available soon!

How about another Groupbuy?

I know you’re already on the list, but anyone else who wants to help Sofirn gauge interest in a host version, please make sure you add yourself here:

Collecting interest for a Sofirn C01 host version

[image] After the C01 with Yuji leds was sold out the C01 did not come back, Sofirn told us it was because Yuji did not have the leds anymore. I had asked if other high CRI 5mm leds could be sourced and although there was some progress in that, there were some problems so that still has not happened. So now I asked Barry if Sofirn could make the C01 host available so that people can solder in their own 5mm leds, and I’m really glad that Sofirn is willing to do that. To be clear…

Very cool, will be buying quite a few of each!

[ReManG]

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.

Congratulations on your progress. Many people are very excited.

I think the C01 is a great little light, with all of the LED options you are putting in it, both 5mm and HiPower

Im loving my C01R… please make more

Now I have a BIG Request

please offer a C01 Copper!

after that, consider Titanium, Timascus, and Mokume…

oh my racing heart… I need to calm down
lol

[JaredM]

In for two.

@defloyd77

I’d be down for a 3400K and a maybe even a red LED version depending on how bright the light is.

Could the output be lowered for the red version?

How low do you need the red led C01 to be? Low enough to stare at the led directly? If so, it need to be lower than 1LM

But will most people like a red led light with only one brightness lower than 1LM?

It’s hard to test the lumen of a red led, but we can make sure it’s comfortable to see the red led directly while light is on.

[Muto]

Down for 5 3400k’s and 2 of the red ones.
THANKS!

I think
5 lumens on a single mode 5mm Red LED is most useful.

that is
Half as bright as the second mode on the C01R

for sublumen option, offer more of the 3 mode C01R
the 0.5 lumen low mode of the C01R does a great job for a red moonlight

and if you build C01R with 730nm
the brightness will be good, a bit lower than 660nm on all levels…

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.

[jon_slider]

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.

Keep the C01 a no-frills light. Tighten head and have enough light. Please.

@run4jc

I’m really late to the party, but I’d love a half dozen of the 3400k!

And 3 of the red….

[MascaratumB]

YES!!
I’m for a groupbuy, I’ll be buying some for friend’s kids
And for me In different colours
