Can anyone verify latest (non potted) C01 have orings around emitter at cone base?
yes, per post 3174

I checked a potted black one and a non-potted orange one, both have o-rings in place around the led.

Yes.

As I recall, there was one report of one C01 from the first batch not having an o-ring around the led and this incident has been quoted many times in this thread, and as things go nowadays, things that are repeated enough become the new reality.

Yes, both the potted and unpotted C01 have o-rings,

yes orings,

Its just incredible, there are Orings,

and on all kinds of Sofirn C01 there are O-Rings
This is very important,

because the fake news is not reporting it,

there IS an O-Ring around the 5mm LED Innocent

we will be presenting the evidence later

Thanks All.. So I’ll take it as a YES? LOL

Edit: All of page 106 is about orings confirmation and potting info..
Hot damn, Glad I ordered Black and Green!

glad youre happy you ordered potted lights Smile

I avoid black flashlights,

I ordered Orange, with O Rings.. lol

I dont think I need my lights to be potted, I like Orange with O Rings
(I hope nobody asks if they can order O rings.. lol)

This UnPotted C01 seems plenty durable enough for me:

Smile It was not you who made a widespread rumour out of your remark, that was all the people who half-read it or even only read the replies.

I am hearing now on CPF some of the supplied head orings maybe thicker, or thinner, than what was, or is currently supplied lol.. I think it’s pretty cool they offer spares thick or thin..

In case you missed it, my son (older and stronger in the meantime) did an even more brutal test on the 2020 version, although this time it was a potted one. Looked very beaten-up but remained fully functional after the test.

When I received mines (from Sofirn site), I tested an orange one (which doesn’t seem to be potted).
Threw it up to the air in my room for 2 or 3 times, let it fall on the floor and…still works Big Smile
It just got 2 small bruises in the head Innocent

Love C01 but not the Red Led version.
Irregular beam with artefacts
Led is not centered,maybe miss Oring

O ring should center it, Led a bit crooked and can see space
can’t diassemble now it’s potted.
But classic C01 is wonderfull

Yes, it is.

People devised methods to get the 670nm C01 more floody with a more even spot. Maybe this is something for you.

I tried various grades of sanding on one, and the beam really improves but think I loose a lot of light. I should have measured the output before/after so I can not be sure, but compared to my second red C01 it has 30% less output

That’s to be expected. Are you sure that it is really the total output and not just only throw? And lower output doesn’t sound bad for a red light that is intended to be used in low light conditions.

How many lumens does your C01 Red produce, in stock form? I would like to crosscheck my meter with yours..

on my meter it only makes 1.2 lumens

I consider the C01 Red pretty useless, except as a spare battery carrier

imo sanding the LED dome will not make the light more useful, just dimmer

how about potting the whole “cone” where the led is with clear acrylic, kinda turns the whole thing into a big TIR lens and shouldn`t lose any light, if it remains the same (and it shouldn`t be) doing scotch tape over the front would now be possible.

Potting the front with clear acrylic will remove the lens function of the front curvature of the 5mm led, it will turn the light in a sort of mule, but with a weird reflector effect. Could be a nice beam by chance though.

I measured both red C01’s properly, and it is worse: the untreated one I measure 0.45 lumen, the one that I sanded the reflector and led of I measure 0.21 lumen. But it is not guaranteed that before the sanding operation both lights had the same output so it is kind of a bad experiment Facepalm

About measurement cross-checks: this is about the worst way thinkable to check light measurement contraptions. First we do not have an idea how much variation there is between output of different red C01’s, could be a lot. Second, the region of the spectrum that I found luxmeters to have the highest errors is in far red, usually they read multiple times too high in far red (as also seems the case with your luxmeter), even if the performance over the middle part of the spectrum is very reasonable.

red C01 … 0.45 lumen

thanks!

you probably used a different conversion factor than for white light

in any case, very helpful

I find the C01 Red rather dim, and the beam is poor. Sanding the LED makes the output lower, and the beam is still not very good..

I prefer the C01R.. it has a lower minimum, plus two higher modes, and a very nice beam

No. I have seen the spectral sensitivity curve of my luxmeter (a Mobilux class A meter) and it is extremely accurate even at the flanks of the visible spectrum. So I can use the same conversion factor for all sources of visible light.

ok, good to know your numbers are solid for both red and white, with the same conversion factor

my output value for the C01 Sophia is 6.6 lumens
I think that approximately matches yours for the C01 Sophia

so since my red reading of 1.4 lumens for the C01 red is 3.5x higher than your reading of 0.4 lumens, I think you are correct Smile

very helpful

Does change resistor will incerasse output of Red C01?

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 Facepalm ). This is really bright. Lots of pleasant light from a 5mm LED. Highly recommend.

Yes, yes, there’s an o-ring.
