With a set of 10 lamps there is a clear color difference. I didn't notice the CRI rating in listing (83). Those that came were marked CRI: 80.
Pros
COLOR SELECTABLE (CCT adjustable/changeable) Correlated Color Temperature (CCT) Options: 3000K (Warm White), 4000K (Pure/Natural White), 5000K (Daylight); The color temperature can be adjusted simply by flipping the lever on the junction box (see photo); If you're not sure what color temperature is right for your room, this product is for you. By changing colors you can find the right color.
