If Sofirn is listing them on Aliexpress, I hope we can get some before they sell out. Or have they allotted BLF a quota?

The interest list is still under 1000, and there will be 2000 made with Yuji leds, so they will not be directly sold out.
And if you do not neccessarily care for high CRI, if this light sells out quickly, no doubt Sofirn will make a low CRI version (with more light and narrower beam) at some point.

I have just asked to Sofirn if will be possible to buy the (single) driver of the new C01.

I see a lot of interest in this small keychain, Yuji LEDs are very much to blame. Recently I bought some Yuji Leds in Mountain Electronics but they are already sold out.

LOL, to make this light feel a bit more collectible, no pressure of course Big Smile :
Barry made it clear once more that these 2000 lights will be the last with Yuji leds because, according to Barry, these leds are really discontinued.

Today 300 pieces of the black version will be sent to the anodisation factory. They want to make the C01 available during the 11-11 sale. Sounds ambitious to me but I have no idea how things are working over there.

So any idea what the plans are after the Yuji run?

You correctly notice that the bottom light is not 5600 Kelvin, it appears 5100K (middle I measured 5600K and top is 3200K, so the C01’s are spot-on).

Djozz, did you do a spectrometer test on these? Sorry if I missed it.

I have the E01vn with the 3200k Yuji and I like the tint on the SST-20 3000k 95CRI much better. So I just want to see how it compares. Wondering if Sofirn can offer a more expensive version with the SST-20.

That would be a different flashlight. The C01 uses 5mm DIP leds and that makes the construction very simple and robust. Using SMD leds requires a construction with lens, optic, ledboard, shelf etc., it may be that Sofirn makes a AAA twisty like that but it will not be a C01 but a new flashlight type.

I probably have posted spectrometer results somewhere in this thread, but I did them again for you.
Here’s a comparison between 3000K SST-20 (spot from Carclo 10507 TIR) and the Yuji 3200K (from C01, in fact an aspheric beam). So because of different optic not 1:1 comparable but it is how both leds are often used in real life. There is not a huge difference apart from that the SST-20 is clearly warmer tinted, I see no tint parameters which are known to displease people, I expect both to be as good as indistinguishable from an incandescent lightsource.
The Yuji leds are always dim of course, that can have an influence on the experience too.

That’s pretty much how BLF group buys go, and somehow it still works. The list is maintained in Post 287 and is up to date through last week.

Also, it’s been suggested that in this particular case (probably because the light is cheap and getting a lot of interest) the list probably won’t be used for direct online purchasing and might not matter very much at this point. Rather, the list is to gauge interest, and we might get a coupon code or something to make the purchase on Aliexpress where it’s already listed (as unavailable for now).

I’m not an expert in automation but I think it should be possible to generate a PM to all people on the list with the how-to-purchase information.

Thanks Djozz. Wow I’m surprised the Yuji in the C01 has a DUV of -.0037 making it even rosier than the SST-20. Im guessing it’s a different batch of Yuji emitter or the glass making the C01 so much rosier than the Yuji in the E01vn. Comparing the Yuji in my E01vn to other 3000k lights, I’m sure it has a positive DUV because it appears noticeably more yellow.

Now I’m interested in this. Please put me down for 3! Thanks.

@SKV89, you may have been unlucky with your particular Yuji led. I have six of these leds in a nightlight, very low driven btw, that may have an influence, but there is some tint variation among them. Here’s a picture, the tints are not reproduced very accurately but you can see that not all tints are the same.

Makes me nervous to see 7 orders on the page, and “Sorry, this item is no longer available!” Someone please reassure me…

There’s also tests here by staticx57 of both color temperatures, in 45 degree versions, presumably from a different batch, although he didn’t report DUV or provide a chromaticity diagram.

It is clear that I live on my BLF island, I had seen your test in the first post of the thread but not the spectral data later in the post Smile

The colours are the same red and blue that Sofirn uses in other flashlights. But to know how they really look is almost impossible from pictures, they differ depending on who took the pictures with what camera, and what monitor you watch them on. And no camera will get them exactly how they look in real life.

That said, this picture I found of the Sofirn SP10B gives the blue pretty accurately on my (HP 1740 on standard settings) monitor, the red SP10B is not correct, a bit too cherry in this picture, the actual colour is closest to the top part of the red S2+ in the same picture (the bottom part has more yellow from light reflection from the wooden floor, this is absent in the “Sofirn red”.

If Sofirn does their own Sofirn colours as announced, you are not getting more accuracy than this, also not when actual colour samples of the C01 arrive (which will not be this or next week from what I gather).

I hope too, the magnet size for this light is not yet tested in practice, I ordered some of the right size at Fasttech many weeks ago but they have not arrived yet. Still think it should work.
