Interested in one. Thanks.
Thanks Barkuti, I expected as much. But in this small of light with a TIR, I wonder if the larger led die will make a better flooder, since there won't be much throw anyhow. Additionally, the xp-g3 photo red is supposed to have more light in the visible spectrum for humans, vs the Xp-E2 photo red, which produces a beutiful tint in my opinon, but too many lumens are wasted in the higher spectrum that isn't visible to the human eye, from what I understand. Hopefully someone will post some testing results soon on the new xp-g3 photo red, I also would like to know how the luminus red leds stack up against the cree leds in terms of red color, output, and throw. I hope they can make this light work soon, I'm interested no matter how it the UI and led choice shakes out in the end.
Edit: I may have gotten that reversed about the Xp-g3 putting out more visible light vs the xp-E2 photo red. I'm no expert, just going off the info that djozz and others generously share on the forum. I started a thread on red leds if anyone has more input on their favorite "less-orange" photo or deep red led out there:

Normally I want the most throw (for an outdoors light at night or a weapon light for hunting) but since this light will be for a keychain, I figured flood is the goal. Interested in the 80 degree Oslon in a thrower reflector or aspheric light for its narrow beam angle. I'll try that next since the xp-g3 can't really be dedomed easily (for me), and thus won't help me get more throw like the XP-E2 photo red does.
Interested…please add me to the list.
Is it possible to add a USB charging port. How many lumens on the high mode?
so barkuti u are saying its a bad idea shining 3000k lights before bedtime?
I expect the figure of merit is not the height, but the total area in the blue region as a proportion of the overall light emitted…
Based the currently ongoing research, some of which has started to examine specific wavelengths effects on melatonin suppression, we’ll probably eventually be able to come up with a weighting factor for wavelength in order to properly integrate an estimate of melatonin suppression.
I’d be in for one!
Paired with a standard one, and suitable rubber mounts, these would make pretty indestructible bicycle lights 
Interested in one.
Not this time as this project will be adopting the C01S design. However, there are plans to build a very small 10180 light with USB-port already, see here:
Interested.
Update (January 2, 2020):
Sofirn has managed to create a working prototype. Barry told me they are very satisfied with the beam and color rendition. They have also implemented a new UI with two mode groups (L-M-H, H-M-L), changeable by 8 fast twists. The low mode will actually be a sublumen mode with only 0.5lm. The medium and high modes will be significantly brighter. There's no telling how bright these modes are as Sofirn has difficulties measuring monochromatic light (which is normally always the case with standard integrating spheres). Depending on the current applied to the LED it might be possible to guesstimate the output but it will not be easy to get these numbers.
Enclosed you can find a quick whitewall shot (on High mode) made from Barry's smartphone. Please keep in mind that the actual impression with naked eye is different to what you may see on a picture.
The actual production of this batch will definitely not commence before February 2020 (i.e. after CNY holidays). Sofirn will be trying to increase the lot size to 500 pcs. Hopefully, we will be successful in raising the demand a bit more. Next step is to talk about the host color. I still vote for the wine red ano with a dark colored clip. We will need to wait and see for Barry's opinion about it as the ultimate color might correspond to Sofirn's plans for the colorful LT1 lanterns (which effectively could lower anodization costs to a very small amount). TLDR: The deep red body color is still an option.
If you have any favorite color you deem best for C01R, please tell me here.
Wow, that´s good news 
3 Modes with a Sublumen is a good choice;
But I believe deep red with under 1 Lumen is really dark - but that´s O.K. 
Actually I can´t see the picture with the wine red anodization?
I would prefer a no anodization (sandblasted) version
Btw: I don´t know if it´s important for you but in the interest list you have marked the TLF members;
I´m also TLF
Hallo DrDevil,
Barry's picture of the low mode still seemed veeeery bright, so I guess he did not use the latest prototype with 0.5lm in low mode. That's why I decided to post the high mode beamshot only. The wine red anodization can be found in the OP or in post #348, right above your recent post. ;-) On TLF I will refrain from posting this picture as TLF moderation will not allow it for reasons of German copyright laws. Sorry, if I did not mark you as TLF member but you have stated your interest as BLF member (post #49) that's why I did not specifically marked you as TLF member. If you want me to highlight your name as TLF member, please let me know.
Since we confirmed the deep red emitter I’ll double my request to 2 pieces. Any ano color is fine of the three pictured in the op. Red would probably be my first choice though.
I’m not sure if the ‘red wine’ ano color was pictured anywhere, but it’s not showing up for me in the op
Interested.
Strange...I used abload.de as image hoster, as usual. Can you see this picture below?
No. That one doesn’t show up for me. Checked on my Android phone and PC
Integrating spheres are actually fine for measuring monochromatic light sources, there is no inherent reason why not. It does demand a more precise spectral sensitivity calibration but that should be ok with a commercial sphere.
There is a reason though not to want to publish the numbers too loudly, at 660nm the human eye semsitivity is very low,
the same radiometric power level that gives you 150lm in white light, gives only maybe 20lm in 660nm. That does not sound impressive (and because it does not look impressive either, it is still fair to use the lumen for these leds).
Thanks for the information Djozz. I take back my assumption that standard equipment is less appropriate to measure monochromatic light. Maybe there's a way to help Sofirn measure red light more accurately?
This is really strange as I can see those pictures here. Apparently, it must be some routing problem between www.abload.de and US internet providers. I never had any issues with abload.de so far. Maybe everything will be resolved in a few hours. If not, I will think about using another image hoster.
Could be that they correctly measured 20 lumen at full power and thought that can’t be right :party:
