[Available again! - BLF special edition light] new Sofirn AAA twisty high CRI 5mm LED

Oh, Sorry for not clarifying :blush:

Yes both are Sofirn C01, 5600K and 3200K

Here is a direct comparison with the Lumintop EDC01 on low and Med

Without direct comparison it appears to be a pure white :+1:

Doesn’t look too bad to be honest. One is on my way anyway but I was just wondering if I’m not gonna be embarassed if I give it as a gift to someone :wink:

Thank you for the photos
The EDC01 w XP-G3 has Green Tint, and is Not High CRI, so not the same Quality of Light, as the Sofirn CO1 w Yuji

For people that want to go beyond the single mode Sofirn C01, but still with High CRI in AAA size, I highly recommend Clemence’s latest offering, a High CRI 3 mode AAA light

So i threw the clip in my fireplace. The black paint was gone real fast. Waited till red hot and dipped it in olive oil(extra virgin lol). Then i tempered it by hanging it on the metal fireshield(around 200c) for 2 hours. Its much harder now but can still be bend.

I would say definitely yes, that the artifact in the Sofirn C01 is caused by the shiny cone.

My Utorch S1 Mini with shiny bezel, has a round artifact in the center of the beam, on right.

l-r 2000k E21a, 4500k N219b, 6500k XP-L

the light on the left has black magic marker on the bezel, the center light has black paint, on the right shiny
Note the three lights pictured, Utorch S1 Mini, have Aspheric Lenses, same as the Yuji LED. They are NOT supposed to have a hotspot.

conclusion
Shiny bezel causes hotspot artifacts in Sofirn C01 :wink:

That’s good info polarweis, thank you. :+1:
You said you went to “red hot” & got some results.
When mine get here I think I am going to try going a bit hotter, into the ‘Orange hot’ range; temper a bit hotter too & see what happens.
It would sure help if we knew what metal the clip was made of.
…….
Edit: It would seem to indicate, since you were able to achieve some degree of hardness; it is not ‘mild steel’ at least.

Perhaps not quite as throwy as the initial GT, but thanks for indulging my curiosity about how it would look with that big reflector. :smiley:

Yeah i think with more heat it will get a little bit harder. It will get a strange blue color tho.

They say its hot enough when its not magnetic any more. Mine was still magnetic. I think you really need a torch to get enough heat.

Yep, you are correct about the “not magnetic”. :+1:

A torch will work just fine or a ‘heat treat oven’ if one has access to it. Fortunately I do.

It will be a ‘crap shoot’ getting it right on this unknown metal… but if we can figure it out by trial & error… we can share it for anyone interested.

The info you shared is a great start… :+1:

Just want to say that I received mine 3 days ago. I bought it 10th November, so it took 32 days to get to the UK. I like the 5600K tint alot, it's the best cool tint I've seen so far. Great job to everyone who was involved to get this light into production!

Thanks John, good to know. I ordered mine a day after you, so hopefully they’ll be here soon!

Mine are in US last week, but damn, once in ISC cutoms in New York OR Chicago….it can be another 2 weeks to get to me in southern US….I’m used to it after so many years, so I’ve learned to just wait and wait and wait……. :innocent: :smiling_imp: :person_facepalming:

When I saw the top picture, I first thought it looked like that itty bitty animal they’ve found that apparently can’t be killed! Facepalm

Perhaps this is good info who receives a C01 with bending clip that does not have any springiness to it.

Btw, I managed to convince Sofirn that their clips are faulty, they admit that the heating process was wrong and they sent what is left of the batch back to the manufacturer for improvement.

Inspired by polarweiss I tried his method of hardening the clip, warmed up to orange, quencing in vegetable oil, keeping it at 200 degrees for 2 hours. Nothing happened, fail, no springiness at all was achieved.

Then I did not care about the clip becoming brittle anymore, blowtorched it to almost yellow, next to the fast running tap, and while orange/yellow dunked it under the stream and presto: perfect springiness without being too brittle it seems sofar.

I video’ed it:

Thank you djozz!! It appears you got the right ’formula’…… :+1:

Heat to yellow-orange & fast running water quench.

Anyone tried runtime on lithium yet?

If that is the case, a glass of “aqua on the rocks” could even be better.

Won’t it completely burn?

I’m still waiting for my 2 lights :expressionless:

Very true…. :+1: Might be worth a try to see???

Lithium ≠ Li-Ion.

Lithium primary batteries (Energizer Ultimate Lithium L92) are completely fine to use, Li-Ion on the other hand should not be use in the C01 (bad things will happen if you do).
