Currently published data limited to R7000. Actual product are available up to R8000. Will take months or years until the R9050/80 launched.
Also, theres 7070 package ready to launch with weird but practical footprint: 149AM (9V)
Available up to R9050. Designed for stadium lighting.
And 8080 package too
And there’s rumour that 149AM R9080 is already there made exclusively for Panasonic
Football is very popular in Japan……And I guess that’s why there’s a special request for it.

I overlayed some graphs from the nichia website, red is 219c 70cri 5000k and blue is 219d 70cri 5000k
It seems that spectrum is slightly different and forward voltage is lower
What might be very interesting is the fact that it seems to be throwier too
Here is my quick analysis of the 219D based on the info on the website and your graphs 1C3 compared against 219B and 219C datasheet values for R70 LEDs:
Lumen output (700mA):
219D: 336
219C: 322
219B: 302
~4% efficiency increase (vs 6% increase going from 219B to 219C)
A quick calculation using a ruler against your graphs 1C3 I get the follow voltage values @ 2.4A:
219D: 3.35V
219C: 3.45V
219B: 3.4V?
~3% efficiency increase
~7% total efficiency increase
Luminous Intensity:
219D: 115
219C: 92
219B: 76
25% increase (vs 21% from B to C)
This isn’t as large a change as we saw going from the 219B to the 219C but given the compounding effects of better efficiency / less heat being created as efficiency inches closer to 100% and a narrower beam this looks like it could be a nice upgrade to the 219C, especially in lights where more range is needed.
Thanks for the comparison, Manual Man. So there are some improvements to be expected from the 219D, that is really nice. When they become available things that the datasheet does not tell can be measured: how does it behave at high currents, how does it behave in the different optics, what do the tints look like.
