CRI is a pretty bad rating system. They are showing the full spectrum graphs which is what you'd want anyway. Spectral Similarity Index (SSI) is the better number

Sure, but I don't see them mention what they're actually using for LEDs at all. They mention a "colour fidelity index" but I'd expect a manufacturer part number or something so I can pull the datasheet.

Funny enough, the best evidence for this study is that they should probably move somewhere with more sunlight if they can't spell "color" right... /s

They are not using an index much, they are showing you actual spectral graphs. Ask an AI to understand how that is the actual info you'd want.

		Is "ask an AI" the new rtfm?
