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:
[image] Nichia 119D SM505, Nichia 219F SM505 D340, Nichia 219F SM305 D320 After the very succesful and high performing 219C, Nichia has brought out 2 successors sofar, the 119D/219D, and the 119F/219F (the 219 version has the standard 3535 footprint while the 119 version is the same led with dual solder pads without thermal pad in between). Clemence, who is a led and flashlight fanatic but who also runs a small lighting business, Virence.com, and is official Nichia dealer, has kindly sent me …
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.
