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, its ability to render colors is thought to be very good to excellent. A CRI of 100 is considered natural daylight and is assigned to the sun itself.
The Color Temperature is expressed in degrees 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
Day Light: 6200° K to 6800° K
