Interested in one of each, and thanks!
This was pointed out to me in a message.
I am too busy to run another project right now but can give you some pointers on setting up the Group buy if anyone needs help.
I would be glad to help setup a group buy… but my free time comes and goes… so I dont want to take it on by myself…
In for two of each
I could help out with the list and with handling polls, although I’m not familiar with what sites are preferred here. I’m most familiar with Surveymonkey.
On a side note, I think people have already expressed interest in a similar amount of the Sofirn light as the original Fenix idea. Probably should set up a new thread fairly soon.
As far as LEDs go, I think sticking to the original Yuji LEDs would be a good idea. Let Sofirn offer UV/Red/low CRI variants later.
Three colours total? One should probably be black. I’m not familiar enough with Sofirn’s colour ano quality to offer educated suggestions, but I like blue based colours like cyan, navy, purple, green, and shades thereof. The spectrums offered by Convoy or formerly by L3 Illuminations give some good ideas.
I still do not think a new thread is needed for this. The main objective is that the flashlight will be developed and that is being cared of and the interest list is for Sofirn to get an idea how wanted this light is. This thread is further used to gather ideas for this light and it has produced useful contributions already.
Only setting up a group buy is challenging but that may not even be in order, wether members from the interest list will receive a discount is not sure and for 6 dollar this light is interesting enough already without discount. If later a discount is indeed in order it is early enough to ask for help and find a way to do it (i.e. maybe a not so secret code to get to 5 dollar would do the trick already).
I’m still in, interested in 3 cool, 1 warm.
Interested at least in three warm. Many thanks.
Ohhh, I like the recent developments! Put me down for a 5600K (I wish there was something in the middle, like a 4500K, but hey… I’ll take what I can get!)
I would like this light to have maximum runtime. So I vote 20 mA if 30 mA will reduce the runtime dramatically. These type of lights are not meant to be bright anyway.
I am interested in 3 of ea.
So a total of 6

I’m afraid I will need to do a current/output test this evening, and a 24hrs runtime test at 60mA to see how they last. That will generate some data on what current is best.
Has the question of potting come up? Will the Sofrin be potted?
In for one of each.
originally in for 1. If Sofirn and $6, in for 3 more.
Kind Sir, if you’re in California, I will buy you a drink!
I suggested it to Barry, but had to explain what it is, I’m not sure if that is picked up very well so I may have to emphasize it once more.
Being of a skeptical nature, in the meantime I did some searching for the need of potting drivers and what came up is that it is about heavy components that come loose on impact, such as thoroids with ferrite rings. This light will have a tiny boost driver that needs to produce very little current so it has a very small (lightweight) coil, that needs much larger impact to come loose than a big thoroid. So I’m in doubt if the potted driver of the E01 is overkill or not.
So before I bug Barry about this: is there any experience at all among BLFers of small lights failing from broken-off components upon impact?
Not likely, in fact I’ve never been out of Europe sofar, but if I get there I will hold you to that! 
Only issue I (and another member) had so far was with Sofirn SP10! Somehow the impact (1m above the ground) damage a component or link between components and the light stopped working (even with magnifying lens I was never able to figure what it was).
But the SP10B has a different architecture regarding the driver. So, concerning these even smaller lights, I never had any issue. Don’t know if this helps, but that’s my only experience :zipper_mouth_face:
