Better Nichia 219's today? Prefer Natural or Cool option.

OT - sorry OP

Thanks. I found this nice picture in this thread The CREE "Angular-Tint-Shift" flaw syndrome..It's causing brain damage. .

Question pls: Why does the Nichia 219b have less green tint shift? And any explanation for why some Cree LEDs are described as not having it?

EDIT: In the thread discussion it was mentioned: “Nichia & Luxeon has mastered the phosphor coating & design to make it right.”
