After 219D Nichia comes up with yet another 219 variant. Seems sligtly more efficient (1 bin up) but floodier than 219D. It doesn’t feature silicone-on-glass dome.
There are marginal differences all around.
Like 219D this one is CRI70 only.
Lets hope that these are more resistant than the turn-blue-on-turbo (Folomov 18650S) 219D.
Clemence sent me some, I’m gathering courage to test one one of these days.
We want results!!!
Working on that 
Testing leds may be my most appreciated activity on BLF, it is also the most boring thing to do for me. So doing a led test has become a bit of a hurdle to get , and often more fun projects go first. It is a hobby you know 
Of course. We are aware of it and we all truely apreciate your effort!
Many thx!
219F was tested by djozz, it’s not good:
Disaster… i never thought this could happen
I’ll stick to the C’s…
But the C will soon be replaced by F for good. Based with newer LEDs, Nichia approach seems to maximize the performance WITHIN rated working range, no more.
This 119/219F has performance close to 309/319B with smaller die. Bye bye overdriving Nichia

Dang… another surprise.
Well at least we’ll know what exactly can be done 
There is now 219F-V1 on the Nichia site.
It appears the same except for CRI - there’s 8000 and 9050 instead of 70.
Wow, this might be interesting after all
I hope that they also changed the limited current handling of the 219F, but new high CRI options are always welcome.
