Measurements in an integrating sphere allow the characterization of the photometric and colorimetric performances of a light source or a light system.
Based on a radiometric measurement using a spectroradiometer, this characterization is carried out under COFRAC accreditation (scope available on www.cofrac.fr.) under controlled test conditions, in accordance with internationally recognized standards: NF EN 13032-1, NF EN 13032-4, CIE S025 and LM-79.
Through these measures, we can provide you with accredited reports containing the following characteristics:
- Luminous flux (lumens)
- Light emission spectrum (wavelength from 300nm to 1100nm)
- Color data: color coordinates (x, y), color temperature (CCT), color rendering index (CRI), Ra, 14 color CRI, TM-30 (Rg, Rf)
- Total electrical power consumed (W)
- Luminous efficacy (lumens / W)
- Power factor
- Energy efficiency class *
- Harmonic distortion rate *Flux lumineux (lumens)
