Testing of luminaires for general lighting

Testing of luminaires

Our photometric laboratory offers a wide range of accreditation and extensive experience of our research staff. Test reports and photometric files are prepared individually for the tested luminaires. 
 
The indications of our test equipment are monitored continuously using standards registered by the Central Office of Measures to ensure fully reliable research results.
In addition, except research in the field of lighting technology, the laboratory offers a wide range of research aimed at developing and controlling the quality of lighting products.

The scope of research

Photometric measurements

  • Spatial distribution of luminous intensity with angular resolution up 0,1˚ using classic or fast goniophotometer
  • Luminous flux, luminous efficacy, 
  • Colorimetric parameters:
    • colour rendering index (CRI),
    • colour temperature (Tc), correlated colour temperature(CCT)
    • chromaticity coordinates
  • Goniospectroradiometric measurements
  • Assessment of blue light retinal hazard 
  • Luminance measurements using matrix luminance meter or single-spot photometer
  • Measurements of light source flickering, effective luminous intensity, timing parameters
  • Spectroradiometric measurements in wavelength range from 200 nm to 1100 nm
  • Colour, transmission and reflectance of luminaries materials  
  • Calculations and visualizations:
    • preparation of photometric files
    • isocandela and isolux distributions
    • glare estimations
    • calculations in Dialux.
