CRI value for LED lamps

CRI is an abbreviation and stands for Color Rendering Index. The color rendering is expressed in RA, on a scale from 0 to 100. The light source is compared with daylight. A CRI of 0 indicates that there is no any color. Lighting with a CRI of 100 corresponds to daylight. Most LED lamps have a CRI value between 70 and 90.

What is the best CRI value?

In principle applies; the higher the number, the better the lamp displays colors. So CRI 100 is the very best. However, an LED lamp with the highest CRI is not necessary. We usually make the following distribution:

CRI of 60-79; reasonable color rendering,

CRI of 80-89; high color rendering,

CRI of 90 and above; excellent color rendering, true to nature.

Lighting with a CRI between 80 and 89 has a high color rendering. This display is actually more than adequate for most applications. A higher CRI is needed for companies where accuracy is important, such as spray booths in the automotive industry. Shops and shop windows also need lighting with an excellent CRI. It is of course not desirable for customers to walk out to see what color the product is.

Warm LED lighting

The CRI value is calculated by measuring the color rendering of eight reference colors (R1-R8). An average of this is calculated. This average is the CRI value. However, the CRI value is independent of the color temperature. Color temperature or light color says something about atmosphere.

We express light color in Kelvin. A different light color is desirable in the office than, for example, in a showroom. The right light color also affects productivity. That is why it is important to have a custom lighting plan made. All aspects are taken into account and you can make a well-considered switch from conventional lighting to LED.
