A Few Notes On Color Quality
The Color Rendering Index (CRI) is a numerical system that rates the “color rendering” ability of light bulbs in comparison to natural daylight. If a light has a low color rendering index of 50, it does not render colors very well. If the lamp has a color rendering index of 80 – 95, which is very good to excellent.
The Color Temperature is expressed in Kelvin (K). Low color temperature implies warmer (more yellow/red) light while high color temperature implies a colder (more blue) light. Moreover, the “color temperature” of a lamp refers to how reddish, greenish or bluish the lamp appears. If the lamp appears reddish, it has a lower color temperature (e.g., 2500K-3000K) and is considered to be “warm” in appearance. If the lamp appears to be bluish, it has a higher color temperature (e.g., 4000K-4500K) and is considered to be “cool” in appearance.
Warm White: 2500 K to 3000 K
Cool White: 4000 K to 4500 K
DayLight: 6200 K to 6800 K
