Color Rendering Index

Color rendering index or Ra index, is measured with a value from 0 to 100, where 100 correspond to perfect daylight. The closer to this value is to a light source the better the color reproduction. The problem for LEDs has been that color reproduction has changed over time. Already after a few 1000 hours you see clear changes. This problem is usually experienced on light sources with lower Ra values ​​ranging from 40 to 70. Therefore it is important that when selecting a light source make sure that the LED has a high Ra value between Ra 80-100. Designlights LED lamps usually have between 40,000 and 50,000 hours of service life, and a Ra value at 80-96. We guarantee full color rendering until the end of the lightsource life.
