One thing about CRI is reflection though. When you use an LED with a high CRI then when it illumates your furniture, objects, people etc. it will look like as if the sun shines on it (in terms of colors). But what I would like to have is indirect light. E.g. point the lights to the ceiling and have the ceiling illumate the rest of the room. Not only is this less efficient in terms of electricty (but there isn't really a way around it) but it AFAIK also impacts the CRI depending on what material the ceiling/mat is made of. Any insights here?
