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.”
