For those new to this like me: 2 factors determine beam color: CCT and Duv. Above picture of Nichia 219b and 519a shows how a more positive DUV of 519a gives a more yellowish tint. And a more negative DUV of 219b gives a more rosy/magenta tint.
Below is a comparison with the very popular SST20 4000k in Sofirn IF25a - showing lower CCT’s effect on color, making it more yellowish (and a little greenish). No right or wrong, just different; like the different colors of different light bulbs. Maybe later it would be interesting to compare this SST20 4000k with Nichia 219b 3500k , one of my very favorites because it has yellow tone without the green tint.
But for sure no LED I’ve seen so far could render those lavender leaves like Nichia 219b 4500k. Its spectacular numbers explain this ability: Ra 96, R9 97, R12 79 (holy cow ), Duv –0.0095. As always anyone pls correct me as needed if I make an error.
