It’s hard to appreciate just how problematic LED lighting is without some reference to what ‘good’ old natural light looks like.  That fiery circle in the sky is notable for giving off a relatively even spectral power distribution across the entire color range.  In other words, all the colors of the rainbow are here at full strength.  Absent are the obvious dips and peaks common in LED lighting that make it so problematic.
