Double 4000K, or 4000K and 660nm.
I would be interested in these options if available.
Interested if 1 or more sst20 4000k,!!!prefer 2700k if possible¡¡¡ + 2+ 660nm
interested.
3x SST20-DR on one side might prove more useful
I’ll again list my interest for at least 1-2. I’d love a small-ish 18650 headlamp with 4000k High CRI & (deep) red. Ramping and Type-C recharging would be amazing aswell 
Interested in hCRI 4000K
Same, this is going to be my next dedicated headlamp! (I hope). Ramping and Type C (and maybe voltage-battcheck?) are on my personal wishlist, as well as a nice diffused beam (like on the Wurkkos HD20 on flood, I love the light it produces!)
interested.
thanks
Red on the head is a good idea. Interested
Interested, would definitely buy one at that price. Thanks!
I am definitely interested in a redhead.

Soooo… can we have an update on this project? Is it still happening? When might we able to buy it? Thanks 
Interested ... In for at least a couple ...
Interested
Dang it, let’s make this happen
i’ll be interested too. i’ll take 2.
please do not use rgb leds, i build few lights with them, i used xml leds, the focus is always off, dies are off center, not to mention d25 reflectors are pretty picky, i had 2 with l2, aka fake xml leds, and the beam was horrible, it had a hole in the middle at any distance, when i replaced them with xpg3 the beam became very smooth ,with no rings or holes, sst20 will work just right with them. and besides who needs green and blue light anyway in a headlamp
I’m interested in this as well.
