CRI, or Color Rendering Index, is a measure of how accurately a light source is able to reveal the intrinsic colors of what it is illuminating. Established in the 1960s, CRI is an extremely important measurement for assessing the color performance of a light source.

Understanding Color Temperature of LED lighting

Many of our customers are now familiar with the idea of a "warm" white or a "cool" white being offered by fluorescent and other light bulbs. LED light sources are based on the Kelvin system of measure. A warm color temperature is typically 3,000K or less. A "cool" white bulb commonly has a color temperature of 4,000K and higher on the Kelvin scale. Most of our fixtures range from 3000K-2500K, which provides a good source of warm light for home or office use. Below is a basic scale that gives a good indication of the range offered by LED sources.
