Cri Led Lamp

Color rendering index led light bulbs.

Cri led lamp.

The result is a brighter room but with a much more natural accurate output of light. Incandescent and halogen light sources have a cri of 100. 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. The higher the cri the better the color rendering capacity.

The cri of philips led lighting products is always higher than 80 close to natural light. Many of the incandescent and halogen replacement led lights currently on the market use less energy but are not true replacements as the white light they emit is of relatively poor quality. Natural outdoor light has a cri of 100 and is used as the standard of comparison for any other light source. A cri of 100 shows the true colors of the object.

So when we measure the cri of a 3000k led lamp it is being judged against a natural light source that has the same spectrum as a 3000k halogen spotlight. Led bulbs have grown in popularity recently mainly due to their energy efficient qualities and bright light production. The color rendering index is not very tangible for many people and is therefore hardly noticed. For example a 5000k led s color rendering performance would be compared to 5000k daylight not a 3000k halogen lamp.

Cri is independent of color temperature. Color rendering index for led lights. High cri led strip lighting offers the best of all worlds using a fraction of the energy used in traditional. In terms of cri for led most led lights produce a score of about 80 to 90 on the chart.

The general rule is. Pick from led light bulbs halogen light bulbs miniature light bulbs and specialty light bulbs. That s right despite the awful energy efficiency of halogen and incandescent bulbs they produce a full natural and excellent light spectrum.

Typically light sources with a cri of 80 to 90 are regarded as good and those with a cri of 90 are excellent. When switching to led lighting often only brightness and color temperature are taken into account. The effect of a light source on color appearance is measured in the color rendering index cri on a scale of 0 100. The cri value is another important parameter for good lighting quality especially in the home.
