The D1 has one emitter. The D4 has four emitters. So… does the D17 have seventeen emitters? The planned 8x18650 powered Noctigon was I believe supposed to have 9 XHP35 HI emitters for 16000 lumens. Perhaps this changed to seventeen XP-L HI emitters? Or maybe seventeen XP-G2/Nichia emitters for around 10000 lumens, but with a lot more throw than the M43?
Clemence has already found the R9080’s difficult to obtain, while he has a very direct contact at Nichia. It would be quite an achievement if Hank was able to get Nichia to release to him the few that they make.
So… the D7 (instead of D17) has seven emitters. Maybe like DQG with single 26650 (Well it could be seven XH-P70 emitters buuuut I doubt that)? So I do assume Nichia option is then available for the D7.
