What I labeled as "Quality" LED fixture were the fixtures I evaluated at the lighting store. They were available in color temperatures from 3000 to 5000 and their CRI was 93.
The measurements were made assuming these fixtures were being used to light a bench. The light that isn't directed down, for example fluorescent wrap, goes elsewhere where it might be useful for area lighting, or lost in a dark ceiling.
