Sofirn C01 for 2020

[this_is_nascar]

Is this smaller o-ring a concern? I really hope this doesn't turn into another Olight it3 or whatever it is issue whereas you read about all the lost bezels from them unscrewing on their own.

It comes with a smaller o'ring installed but in the box is a thick one like the E01/C01 yuji use, a spare thin one and a split ring for attaching to key chain(s) if you choose to. For pocket carry you probably should install the thicker o'ring.
The thinner o'ring makes activating it a lot easier, but may also allow it to unscrew in your pocket.

Thanks. I'll have to take a look.

Output comparisons on my meter, using the same battery

6.8 lumens, C01 w 3400k Sophia

7.7 lumens, C01 w 5600k Yuji

11.3 lumens, Fenix E01 w 6500k nichia gs

Ordered my batch from Sofirn, and it finally
SHIPPED on November 12.

Checked tracking status today, and it says:

Port of destination - Arrival
2020-11-19 09:26


So I'm assuming it's now in the USA, correct ?


What's it been DOING for the past 10 DAYS then ? ? ?



Is it still stuck in Customs ? ? ?

Will it get more Specific, as to current location ?


< me puzzled > (and anxious)

[knucklegary]

My order arrived with a return addy from Mr Lee, NY state.. Makes me wonder where exactly it shipped from?

[jon_slider]

Mine come from Fremont California.. lol

watching tracking is about as reliable as reading lumen specs

things get grouped and shipped to reshipment points than then get sorted and reshipped...

often packages arrive, while tracking says they are still overseas

moral of the story, dont believe everything you see online, be it tracking, lumens, or otherwise

[knucklegary]

Either way it only took about 11 days from order confirmation to delivery..

Just ordered 5 more Sophia's before sale ends soon..

I think the orange ano reminds me of childhood favorite popsicle flavor🍊

Jon, are the new C01 oring'd around the emitter like previous versions?
I'm thinking of bead blasting the inside cone and glass tip to flatten the hot spot,, but only if sealed around bulb base with oring

Fremont, CA.. I know that area well (-;

[jon_slider]

yes O rings are present on both potted and unpotted C01


if goal is to eliminate the hotspot focus, and produce a more even beam, like the first run C01,
then

matte finish the aluminium cone only, sandpaper or whatever

I suggest you NOT alter the LED lens on the Sophia. imo that is an Optical Lens and is responsible for the nice beam shape, with a clearly defined perimeter. Sanding the optic would diffuse the perimeter, which is not my preference.

I like this sort of beam, which is similar to the Sophia and Yuji:


I find a true Mule, less to my liking.. too much wasted diffused light out the sides, for me:


Mules are actually brighter in the center, when illuminating a subject, my camera does not like a mule lightsource, as much as an even beam with no hotspot

[knucklegary]

A lightly glass bead (2 psi blast) effect would be more of a frosted appearance on the optic. On the Al cone it would take away the polished finish.. But yes, on the optic could alter the beam shape. I will first try with a cover cap over the Sophia emitter to see what a softened reflector effect has on beam
I was planning to blast ano finish off brown one anyways..

[Timothybil]

yes, but the Fenix E01, it is no longer in production, and it had a Low CRI LED

as far as durability, that is a vague term and imo potting does not have a noticeable effect on the function of the light.. I posted two videos, one of a potted light and one of a non potted light. Both lights survived getting thrown on the ground repeatedly.

In any case, if you want a Potted C01, buy the Black, Green, and Red ones, they are potted.

Sofirn, working with the BLF community, has developed a replacement for the E01, The C01S. Same size and form factor, multiple light levels, and best of all, high CRI. I have heard of almost no failures on that other board, and the price is definitely good.

[knucklegary]

C01S is a nice light, SST-20 4000k tucked behind TiR optic.. The C01 Sophia is a whole different pup. It's also Hi Cri but low lumens with single mode. Similar to E01, and replacing the later offered Sofirn C01 Yuji

I'm enjoying both the C01S and C01. As I've said before, they really compliment each other.

[rookiedaddy]

so I'm curious about the runtime of these Sofirn C01 and...

above is after 48 hours...

and after 68 hours...

... I'm impressed...

[Tejasandre]

Cool

[Timothybil]

Just unpacked four Co1 lights from Sofirnlight. Don't know what I'm going to do with then, but at $4 each I couldn't turn them down. Since I just got them I am assuming they use the Sofie LED. Really nice smooth beam. I EDC one of my C01S lights, and sometimes a Lumintop Tool 2.0.

[aginthelaw]

I paid $9 for my C01r’s. Anybody getting those models for $4?

[Tejasandre]

I paid more for the red too

[Katherine Alicia]

I paid $9 for my C01r’s. Anybody getting those models for $4?

yup, 6 of them

[bykfixer]

Thanks for the run time graphics RD.

I noticed when using the thin o'ring that if you hold the light with fingers on the bezel it rotates on so easily that you can accidently rotate it to off as well. Not really a good thing when you weren't expecting the light to turn off. Oops.
Easily rectified by swapping o'rings but I prefer the ease of activation and adapted my grip.

[jon_slider]

yup, 6 of them

If you paid 3.99, you bought C01 Red 5mm, single mode

C01R is a different animal, costs extra, has 3 modes

fwiw
C01 is 3.99, has one mode only
C01S is 6.99, has two modes
C01R costs 9.99, has three modes

people get the different models confused
post #16 lists all the different models

[Katherine Alicia]

the C01R is the first of the series that I bought (a while ago), I have 6 Sophia lights and the 670nm version (so 8 in total).
I don`t have the C01S or one of the Yuji lights (though I would like one!).
and that`s about it

[jon_slider]

I paid $9 for my C01r’s. Anybody getting those models for $4?

no
nobody is getting C01R for $4
I paid 9.99 for my C01R 660nm Red that has 3 modes,
I am very happy with it, the mode options are excellent

yes
people are buying those other models that cost $4
I paid 3.99 for my C01 670nm Red that has 1 mode
I do not recommend it because it is too dim, the beam has artifacts, and it is potted, which makes changing the LED more difficult.

I also bought the C01 w 3400k Sophia
Highly recommended

Hey Byk, I went through all my zip packets of orings searching for thin ones and can't find any differences with my calipers

I do have another order of C01 pups showing up soon, black and green. I'll check those, maybe that's where Sofirn packaged the thinner orings

Imo, for key ring pocket carry the stiffer (thicker oring) twisting action, lubed well, is best for no accidental pocket or butt turn-ons

[jon_slider]

It seems Sofirn has shipped me a couple different O ring sizes
though each pair is the same in a given packet

some are larger in diameter some are smaller in diameter
both are thicker than the O rings I get with a Lumintop tool

[bykfixer]

So none arrived with a small zipper bag containing 1 thick, one thin and a key ring?

Two black and one blue that I bought at the Sofirn site all came with them and thin o'ring installed

[jon_slider]

Dances with O Rings

So none arrived with a small zipper bag containing 1 thick, one thin and a key ring?

yes, mine came with a small zipper bag and a key ring, and
no the two O rings are not; 1 thick, one thin

in my case,
the two on the left are larger than the two on the right
but each bag contains two matching O rings and a metal jump ring:



also note the plastic bag is different.. lol
cheap thrills

[bykfixer]

Did your lights have the thick ones installed too?

[jon_slider]

I grabbed my Yuji version and compared to the Sophia. I noticed the Sophia was a bit easier to twist than the Yuji. Looking at the o'rings the Sophia comes with a smaller one than the Yuji but in the package was a thicker one with a thin one and a split ring for attaching to a key ring. Frankly I prefer the operation with the thinner o'ring for night stand use. If it travelled on my car keys I'd opt for the thicker o'ring.

smaller, thick, thin.. some very fine distinctions here :-)

Is this smaller o-ring a concern?

Im getting confused, thin, or small, or thick and small...

if the small one is the thin one, or even if the small one is the thick one, if the head is too loose, read on for some coping solutions...

Did your lights have the thick ones installed too?

I took the O ring off one C01 670nm Red and it matches the thick smaller ones, in the bag on the right.

It is very easy to turn the head, I would not want it any looser.

If I wanted to add resistance, I would use a little bit of sticky grease, such as Nyogel 767a or Tef-Gel.

Regular automotive dielectric grease is also sticky and could work to keep a head from spinning too easily.

[knucklegary]

Okay, now i see the differences, same size oring cross-section with different size I.D... Nope all of mine are the same ID with clear bag zippers.., now I'm really feeling like odd man left out!
