The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

    This light is used as a night light on my stove. I'm very happy with the amount of light this product gives (not too bright but bright enough so I don't burn myself when I am using the stove top without the main kitchen light being on.
