CRI OF LED HIGH BAYS

Chromatic performance of an LED high bay?

There are many factors to consider when choosing our LED high bay, but without a doubt one of the most important is the ICR / CRI color rendering index.

CRI & Lighting comfort

The CRI color rendering index is an internationally recognized system that indicates the ability of an LED high bay to reproduce colors compared to an ideal light source.

As the ideal light or benchmark for comparison, sunlight is used because it is the most natural source and best represents the true colors of objects.

The measurement range of the color rendering index is from 0 to 100.

Where 0 indicates absolute color distortion, while 100 indicates perfect reproduction of all colors.

The chromatic sample of an LED high bay is an independent value in each of the 14 colors defined from R1 to R14.

From the result of the first 8 values (R1 to R8) the representation of Ra (chromatic performance index) is obtained, this value is that found in the technical sheets of the LED high bays. The last six values (R9 to R14) give us additional information on the chromatic reproduction properties of the LED cover.

The UNE-12464-1 standard defines minimum values of light intensity and chromatic performance (Ra) necessary according to the use of the part to be lit, being the value of our LED high bay greater than Ra 80, adapted to use in industrial production areas, stores, storage areas, handling and loading of goods, ect.

Example of a spectral test (LM-79) of our LED high bays:

Our LED high bays have been tested in laboratories in Spain, thus verifying and offering our customers the security that they will obtain a luminous comfort in accordance with what is expected and indicated in the regulations.
