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.

E2L with 10507 optic and SST-20-W 3000K 95CRI leds:
how is the list ever gonna be made and be accurate from 49 pages ? it will take hours to get everyone logged and taken care of wont it? seems like its gonna be a huge task .
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).
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.
I see a lot of new posts and quantity updates. Looks like I’d better get the list updated tonight! :partying_face:
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.
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).
