What is Color Rendering Index (CRI)?

The Color Rendering Index (CRI) is measuring the ability of a light source to simulate the colors of different objects accurately in comparison with the sunlight. Although there are critics of the subjective color rendering in practice, the CRI is widely used as a measurement of the quality of the light. Higher CRI corresponds to etter quality light, in scale from 0 to 100.

Generally LED lamps score above CRI 80, which is higher than many other light sources. LED Lamps with CRI above 90 are used for visual inspection tasks.

You should consider also the CRI (quality of light) and your individual visual preferences, but not only the luminous efficacy, when choosing a LED Light . Some people like the more yellow Warm (Soft) White light that resembles the light from the incandescent lamp. Other prefer the brighter and more true-color rendering Cool/Daylight white.
