Colorimetric tests

ENAC Accredited Colorimetric Tests

LED luminaires: UNE-EN 13032-4; CIE 250; CIE 15; CIE 13.3. 
Luminaires with sources other than LEDs: UNE-EN 13032-1; CIE 250; CIE 15; CIE 13.3.

In addition to the amount or distribution of light provided by a luminaire, one of the aspects that we can easily appreciate visually is the color of the light. The analysis of the colorimetric characteristics of the luminaire can be done by measuring its spectral distribution.

From the measured spectral values, the different colorimetric parameters can be calculated.

Colorimetry test report: 

The results provided in a colorimetry test report can be: 
  • Normalized spectral distribution. 
  • Color coordinates (x, y). 
  • Color coordinates (u', v').
  • Correlated color temperature and desviation from the black body (Duv).
  • Color rendering index ( Ra). 
  • Angular variation and angular uniformity of color.

Test and calculation results are always provided in our reports together with their corresponding measurement uncertainties.
