PHOTOMETRIC AND RADIOMETRIC LABORATORY


PISEO has state-of-the-art photometric and electrical measuring equipment for the characterization and qualification of light sources and lighting solutions.

Measurements

Photometric and colorimetric measurements

  • Total luminous flux (lm)
  • Emitted spectrum (360 nm to 830 nm)
  • Colorimetric data: color coordinates (x, y), color temperature (CCT), color rendering index (CRI)
  • Light distribution (.ies, .ldt files),
  • UGR, Ti
  • Luminance (cd / m2), uniformity
  • Chrominance
  • Optical Flicker

Electrical Measurements

  • Total system power (W)
  • Luminous efficacy (lm / W)
