Laboratory for Lighting Analysis and Testing

Report

The services and measurements provided by our laboratory include:

  • Absolute photometric measurement (EULUMDAT or IESNA)
  • Symmetrization of results based on the DUT axis
  • CMAS: color uniformity verification using MacAdam ellipses
  • Stability verification: DUT stabilization checks with consecutive illuminance measurements
  • Smoothing function: mathematical correction of inconsistencies in the polar diagram
  • Custom reports: generation of PDF reports starting from LDT/IES files or spectral data

European Product Registry for Energy Labelling – EPREL and SVR 36‑83 Spectrometer

The SVR 36‑83 spectrometer is used for spectral irradiance measurement and the calculation of colorimetric parameters, including:

  • Tristimulus values X, Y, Z and components X1, X2
  • Chromaticity coordinates x, y (CIE 1931)
  • Chromaticity coordinates u’, v’ (CIE 1976)
  • Correlated Color Temperature (CCT)

 

  • Color Rendering Index (CRI)

  • Test Colour Samples (TCS) provided by the CIE method for CRI calculation

 

  • Chromatic difference (DC)
  • Fidelity index
  • Gamut Area Index (GAI)

 

  • Verification of DUT color uniformity and graphical representation of chromatic coordinates on the Planckian locus
