OMG guys! Thank you very much!
Thanks Djozz for testing this Ying-Ding: Yinding "5050 30W" round die domeless led tested . Everybody should see and like it. This is something we strive since very beginning of led flashlights!
I can’t follow progress any more… So thanks a ton 
Yes… Small Osram green beats everything on lux meter but I don’t actually see any further in a night with it comparing to white brothers (I actually see further with white).
I also got and build one with HHL532.TG New Osram Black Flat but I was not aware that it has high forward voltage so I did pill with long 24 AWG wires, steel un-bypassed spring, and bypassed tailcap spring… Got 4.1A current draw and similar performance like small white flat at 5A current draw. I can confirm it is suitable for FET drivers!
So thanks to JaredM we also have HHL532.TG (New Osram Black Flat) OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm² - #1374 by JaredM. So if you’ll take it is dirt cheap and for FET setup just do your best without adding resistance(thick and short gauge wires, bypasses everywhere, and Samsung 30Q ), although I can’t still confirm 100% (I did resistance FET mod with HHL532.TG because I thought it behaves same like white flat 1mm ) this emitter should beat Small White Flat in performance.
Exciting things are happening guys… I like all new stuff!
Worth to mention that New Osram Black Flat fits to 3535 footprint as Cindirela shoes!
Also worth to mention that New Osram Black Flat does not have electrically neutral thermal pad! I never find that as an issue in mine builds (because I think I have right stuff for eliminating that disadvantage) but someone will hate it because of that(guys that always have to use PC artic silver type of pastes beneath 
)…
