I'm a bit confused about the Color Rendering Index for incandescent bulbs vs. LED ones. Incandescent bulbs claim to have a CRI of 100 (the highest possible), whereas a 5000K (daylilght) LED bulb claims to have a CRI in the upper 80's. However, under 5000K LED light in my bedroom or closet, I can see the colors of my clothing perfectly. Under incandescent lighting, I have trouble telling navy from black (pants, socks, etc). Before I installed 5000K LED's, I have mistaken black for navy several times.
I might be one of the unusual ones, but I much prefer 5000K over 2700K. I know a lot of people, especially women, who cannot stand 5000K; they MUST have 2700K.
