zebralight is notorious for selling green tinted non-nichia leds, based on mcadams ellipse. greener is brighter
iow, they land above the BBL (and in the upper part of the mcadams circle)
people love their zebras. they do other things well, but not tint, nor CRI R9 (red)
.
Nichia was notorious for selling High CRI LEDs with High R9 CRI, and with tint below the BBL, particularly in the 219b series…
imo 219b are an all time classic
buy now, before they disappear:
those are 9080 LEDs…
better than typical 9050 LEDs
the first 2 numbers are the CRI Ra (average CRI), iow 90 CRI or better
the second 2 numbers are the CRI R9 (Red output), iow 80 CRI or better in the Red spectrum
examples of 219c 9050 LEDs
(to illustrate the R9 Red bar):
