Cri Led Lamp

High cri led lighting is a light emitting diode led lighting source that offers a high color rendering index cri.

Cri led lamp.

For example a 5000k led s color rendering performance would be compared to 5000k daylight not a 3000k halogen lamp. Led bulbs have grown in popularity recently mainly due to their energy efficient qualities and bright light production. When switching to led lighting often only brightness and color temperature are taken into account. Pick from led light bulbs halogen light bulbs miniature light bulbs and specialty light bulbs.

Typically light sources with a cri of 80 to 90 are regarded as good and those with a cri of 90 are excellent. The general rule is. 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. 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.

Incandescent and halogen light sources have a cri of 100. 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 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.

Color rendering index for led lights. The effect of a light source on color appearance is measured in the color rendering index cri on a scale of 0 100. A cri of 100 shows the true colors of the object. High cri led lighting high quality energy efficient high cri not all white light is the same.

The higher the cri the better the color rendering capacity. Cri is independent of color temperature. Natural outdoor light has a cri of 100 and is used as the standard of comparison for any other light source. The cri of philips led lighting products is always higher than 80 close to natural light.

That s right despite the awful energy efficiency of halogen and incandescent bulbs they produce a full natural and excellent light spectrum. The result is a brighter room but with a much more natural accurate output of light. Color rendering index led light bulbs. 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.
