It works nice in my S21A with OP reflector.
Oh, there are actual gaps between the emitters.
I did not know that.
Well, I’m currently in talks with fogofwar so he can get samples 
Yeah OP is fine, it only produces a darker spot with SMO reflectors and some clear TIR optics.
Can probably just adjust the reflector height a little until the spot goes away.
I updated the spreadsheet with all of the new demands.
And yeah, I’m currently in talks with the manufacturer to check if he could send their current CNW/CW samples(5700-6500k) to fogofwar to see if the donut hole problem is a big thing or not.
In the meantime, I’m still looking for a similar LED as an alternative with a single die 
Donut hole is only a problem in small SMO reflectors.
I’ve been using XHP50 gen1 which is exactly the same layout like this emitter and in OP reflectors it’s not a problem (even in some tiny ones).
Few specific models (super throwers) had visible donut hole.
Long story short, yes there will be a donut in some setups.
I still need it…
Yeah, but testing is still good.
It might be domeless, but we want optimal beam quality
Don’t worry: I haven’t found another manufacturer capable of making such an LED yet with a better emitter setup, so everything is good.
It’s our “only” current option unless someone at Nichia/Luminus/Cree/Getian decides to actually make something like this
5 3V for me.
Added.
Update my amount of led from 3 to 10 please
Done.
I am in for 20
I salute your engagement 
I’m in for 4, so long as an actual test shows no donut hole.
I already said it on Reddit - but please put me in for 20, blueswordm.
thank you!
and the closer to 4000k the better for me (4000k is my perfect cct). 4500k is exciting too, though.
Done.
I prefer 4000k for general purpose flashlight. 2700k or lower for bedtime use.
Put me down for 20!
In for 10
I’m in for 5
