A clever move 
Interested in two
Thanks
Thank you all for your support! Meanwhile, we have reached 70%. So, our target line is coming closer. :-)
Nice idea which might be worth thinking about, maybe even in different variants like:
- Buy one, Get one (Buy an SP33, get a free C01R)
- Buy a set of two (C01S + C01R)
- Buy the limited collector's BLF edition (C01S LH351D 2.700K 90CRI + C01S SST-20 4.000K 95CRI + C01A XP-E2 amber + C01R XP-G3 deep red + ....) coming in a nice wooden box with gold-imprinted serial number and all lights in clear anodization ... just dreaming, of course... :-D
I think (and hope many of you agree) these small limited edition lights are like narcotic. Cheap enough to allow yourself just another one and soooo desirable due to some unique features. I just can’t get enough 
Please put me on the list for 1.
Interested in 2, thanks!
I’d be in for a couple if you went this route, especially if the C01S was also BLF.
interested in 1
I’m interested if it is a good red.
What is a good red for you?
Interested.
in for 1
any chance these will work with a 10440 ?
ouch, these are 2V leds that should not handle more than 1.5A. so on a 10440 either the led gets way more current than that and blows, or if the driver is made for it on average 2W of heat must be dissipated by the driver which is rather steep.
Like Djozz already said, not a good idea at all. These red LEDs have a very low forward voltage and are way more sensitive to heat and overcurrent than SST-20 for example.
You could try using a 10440 3.2V LiFePO₄ battery (if these exist) but still the odds are quite good that...
In for two. Thanks!
Interested, thanks Lux!
okay thanks for answer, i realized it was kinda a stupid question afterall 
im used to the olight i3t it can run 10440 so ill stick with it then.
Some statistics per today...
78% fulfillment rate of Sofirn's MPQ,
96 people interested so far,
156 pcs accounted so far,
equals 1.63 Sofirn C01R per each member :-D
