Color rendering index cri is the measurement of how colors look under a light source when compared with sunlight. The effect of a light source on colour appearance is measured in the colour rendering index cri on a scale of 0 100. In most situations we are concerned about the color quality of artificial forms of lighting such as led and fluorescent lamps. Cri is a quantitative measure of a light s ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.

Light sources with a high cri are desirable in color critical applications such as neonatal care and art restoration. High cri led lighting is a light emitting diode led lighting source that offers a high color rendering index cri. Color rendering index cri is used to measure artificial white light sources light sources can be grouped into either artificial or natural light sources. The color rendering index is not very tangible for many people and is therefore hardly noticed.

It is defined by the international commission on illumination cie as follows. Natural outdoor light has a cri of 100 and is used as the standard of comparison for any other light source. Led bulbs have grown in popularity recently mainly due to their energy efficient qualities and bright light production. Our led lights have cri values of up to 98 indicating that our led lights are able to produce white light that approximates halogen or incandescent lighting and natural daylight.

The cri of philips led lighting products is always higher than 80 close to natural light. The result is a brighter room but with a much more natural accurate output of light. The cri value is another important parameter for good lighting quality especially in the home. In terms of cri for led most led lights produce a score of about 80 to 90 on the chart.

When switching to led lighting often only brightness and color temperature are taken into account. Cri color rendering index is a measure of how accurately a light source illuminates objects true colors. A color rendering index cri is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. The index is measured from 0 100 with a perfect 100 indicating that colors under the light source appear the same as they would under natural sunlight.
