Can anyone verify latest (non potted) C01 have orings around emitter at cone base?
yes, per post 3174
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
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:
Now I hate that it was me.
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 
It just got 2 small bruises in the head 
Love C01 but not the Red Led version.
Irregular beam with artefacts
Led is not centered,maybe miss Oring
Thanks for the video djozz!
Very convincing durable little puppies, and the aaa lights are too! (-;
No!
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
