Yes, if you change the 220 (22 Ohm) resistor for a lower value, the output increases, you can even bypass it for the highest output.
So C01 and C01 Red Led have same driver?
I mind to swap the Red Led with the rngwn’ 5mm white
I may be showing my ignorance here, but why would the driver be different? I see the driver having two functions: Boost or buck the source voltage to the correct voltage for the LED, and, in the case of a multi-mode light, make the appropriate supply changes to the LED for the mode selected.
Does the 670nm led have a different forward voltage than the others?
It does have a significant different forward voltage, under 2V, while white leds are over 3V. But still I expect the same driver, but maybe the resistor limiting the current has a different value.
Swapping the red led however requires removing the potting, I read that it is possible but personally I have not attempted that.
Did the same mod djozz did, 32K-EX and bridging the resistor (accidentally removed it 
). This is really bright. Lots of pleasant light from a 5mm LED. Highly recommend.
Yes, yes, there’s an o-ring.
Any AA/A bost driver with white Led can accept a Red led
and tension will be auto adjust by driver?
The only concern will be the max current output.
I think yes, but I have no great expertise in electronics, and have no idea about the “auto-adjust” thing.

if you modify a C01 Red
and have success removing the potting, and installing a Sophia LED
I would like to copy you
please share photos and info,
good luck!
and dont forget to reinstall the O Ring… :innocent:
What is the white washer?Silicone glue or plastic?
Sorry,maybe I will only sand led and try get more flood for go on bath at night…
Anyway my sample it’s brighter than the lowest mode of C01R SST20, both ni-mh batts at 1.2V
Hard plastic, potting compound. They say it can be dissolved/softened with I thought it was thinner. And with heat.
Yes, heat in the beggining and start taking chips of it. When you feel you’re close to electronics then soak it in thiner.
This method was used back in the days with Fenix E01 and Inova X5
For do that better high pressure on Led head or hammering?
Think will be not easy,will try to heat a bit also
Yes, heating it up will help getting it out more gently, this one had an already destroyed driver so I did not bother with heat, bold on the led and full force with a hammer.
The die of Red Led is tiny,sand surface can correct the beam irregulary
but not increase much flood.It need to be cut as I do on rngwn Led
that is super floody now.
Would ask sofirn to made C01 Red unpotted if not too late.
Ladies, those lights are $3.99 each - including O-ring. Not sure it pays to crack open the epoxy pot.
Yeah, and then missing all the fun? This is BLF, with a big B!
A few days ago I used scotch-brite on one of my red C01 (led, and reflector) and it did soften the artifacts. I’ll take better pictures, and upload tonight… I’m not happy with how they turned out.
Do you gain a little flood or hotspot is focussed as before?
Do you consider it useless from a medical point of view also? I remember you had an application for migraine treatment.
If Sofirn do another batch of C01 sublumen / high modes with reversible UI
and ask Led supplier to made also 2000k option would be the cream. Will buy 10
