Color Quality Testing

Color Quality Testing at LightLab International Allentown, LLC is performed using either our Labsphere 2m integrating sphere or our LightLab R80A gonio-spectroradiometer. Both methods are capable of measuring the total light output of the test subject. Raw data includes the total integrated spectral power in each wavelength interval.

Metrics that are recorded during the testing are summarized in a report typically

  • Total Lumen Output (lumens)
  • Total Lamp/Luminaire Efficacy (lm/Watt)
  • CCT
  • Duv
  • CRI (Ra)
  • CIE 1931 chromaticity diagram (x,y)
  • Spectral Power Distribution
  • xy, u'v' chromaticity coordinates
