CRI is a measure of the ability of a light source to render the original color of the object illuminated by the light source. The original color is defined by the color of the object when it is illuminated by sunlight.
The closer the color of the object rendered by the light source is to the color of the same object under the sun, the higher the color rendering index of the light source. The value of CRI ranges from 0 to 100. By definition, sunlight has a perfect CRI with a value of 100.
Note: The higher the CRI value, the better the quality in terms of the light source’s ability to render colors. This is important for lighting applications where color is important.
For example, if you need to light up your meat counter, then if you don’t want the meat to have an old, brown hue, then the color rendering of red is essential. The best CRI is to faithfully replicate the colors of goods and products in the store.
You may have noticed the produce area where the supermarket sells vegetables and fruits.
When using a light strip with a high color rendering index, the product presents a natural saturated color, which looks juicy, shiny and fresher. Therefore, they are clearly more attractive to customers.
The same goes for fresh meat. Under the light zone with high color rendering index, the meat is purple red and looks fresher. If the CRI is lower than 80, the color of the illuminated object will be distorted, as if it is covered by a gray veil. The object looks lacklustre and dull.
From the perspective of protecting human eyesight, long term use of light strips requires a CRI higher than 80. Light with a CRI lower than 80 will affect the human eye’s ability to distinguish colors. Prolonged exposure to light with a color rendering index of less than 80 may cause various vision problems. you may have some question about the CRI, what’s different with high CRI and low CRI? here you will get answer: What is CRI?
