Cri Led Lamp

Cri is independent of color temperature.

Cri led lamp.

Incandescent and halogen light sources have a cri of 100. Color rendering index for led lights. Natural outdoor light has a cri of 100 and is used as the standard of comparison for any other light source.

The cri value is another important parameter for good lighting quality especially in the home. 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 result is a brighter room but with a much more natural accurate output of light. Pick from led light bulbs halogen light bulbs miniature light bulbs and specialty light bulbs.

High cri led lighting is a light emitting diode led lighting source that offers a high color rendering index cri. 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. High cri led lighting high quality energy efficient high cri not all white light is the same. That s right despite the awful energy efficiency of halogen and incandescent bulbs they produce a full natural and excellent light spectrum.

The effect of a light source on color appearance is measured in the color rendering index cri on a scale of 0 100. When switching to led lighting often only brightness and color temperature are taken into account. For example a 5000k led s color rendering performance would be compared to 5000k daylight not a 3000k halogen lamp. The lamp receives a score from 0 100 for each color based on how natural the color is rendered in comparison with how the color looks under a perfect or reference light source at the same color temperature as that lamp.

The cri of philips led lighting products is always higher than 80 close to natural light. The color rendering index is not very tangible for many people and is therefore hardly noticed. 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. The higher the cri the better the color rendering capacity.

In terms of cri for led most led lights produce a score of about 80 to 90 on the chart. High cri led strip lighting offers the best of all worlds using a fraction of the energy used in traditional. Typically light sources with a cri of 80 to 90 are regarded as good and those with a cri of 90 are excellent. Led bulbs have grown in popularity recently mainly due to their energy efficient qualities and bright light production.
