Color Rendering Index is an international system used to rate a lamp's ability to render object colors. 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.

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Great light


I have a shop at home. I had already purchased a mercury vapor light but dreaded installing it. Working from home and having kids and grandkids, I have seen these lights destroyed before. They make a mess and can be hazardous to change. The low profile appearance and heavy duty solid globe make me confident that maintenance will be minimal. The light is brighter than what you can get at most hardware stores. So far I am completely satisfied.
