Short Description

LightFluxColor® light measurement system offers integration spheres with 0.5 m, 1 m, 1.5 m and 2 m diameter. Each system comprises an uncooled spectrometer, an auxiliary and calibration lamp (NIST traceable, software and an electronic rack with power suppliers and switches. The integration spheres are designed per IESNA LM-79 standard and are capable of measuring in 2 pi and 4 pi geometries. The system could be upgrade with an AC/DC power operation module.

Labpshere´s LightFluxColor® (LFC) light measurement system is the most affordable and accurate system for testing LED lighting products per the IESNA LM-79 standard. The LFC has compared with Labpshere´s illumia®plus light measurements system a more simplified operation software and less application-specific modules. It features also the NIST traceable spectral flux standards for highest possible accuracy. The LFC-system is capable of measuring:

  • Total spectral flux (Watts/nm)
  • Luminous flux (Lumens)
  • Luminous efficacy (Lumens/Watt)
  • Radiant flux (Watts)
  • Chromaticity (x,y,u,v), CCT, CRI
  • Peak wavelength, dominant wavelength


  • Testing of luminaires in R&D and production environment
  • Packed and clustered LEDs
  • LED luminaires
  • Automotive lighting
  • LED replacement bulbs
  • Architectural lighting
  • LED Street lights testing
  • Trafic lighting
