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, thereās 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 āauto-adjustā 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 Ringā¦ :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 nightā¦
Anyway my sample itās 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 youāre 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. Iāll take better pictures, and upload tonightā¦ Iām 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
It smoothed out the beam, so itās more even, and a little dimmer. To me, thatās not a bad thing when it comes to 670nm.
Please excuse the missing edges of the beams. I was using a piece of white poster board that wasnāt flat.
The hotspot is still a little overexposed.
These are 10 inches away from the board.
Mod on the left. Stock on the right.

Good result,thanks for share.
Does you have removed Led from host or you successful sanded already installed?
Also the cone seem sanded
Yes, I consider the very low output, 0.4 lumens per djozz (1.4 lumens on my meter), of the C01 670nm, to be weaker than I prefer.
I like the second mode on the C01R, which on my meter is 10 lumens, for red light therapy.
the eyesight study used 20 lumens 670nm red, I consider that more than necessary. imo 5 to 10 lumens of 660nm red is plenty bright enough for my application.
I put the light directly on my painful arthritis. For migraine the light is shined into the nose.
Barry said this is the last batch of C01
thanks for the photos
per djozz, the sanded LED is now 0.2 lumens (half as bright as before)
I did it installed. Just took some scotch-brite, a pair of ESD-15 curved tweezers, and ran it across the led. Every once and a while I would turn it on to check my progress. Same thing with the reflector.
