Photometric Measurements

SphereOptics operates a Lighting Test Laboratory for demonstration purposes and for the photometric testing of lamps, LEDs and luminaires. For light sources, displays and signs, we measure the amount of light produced, its colour, its rendering quality and its spatial or angular distribution. We also report the energy efficiency (LOR, luminous efficacy, energy efficiency index). We compile photometric data in .ies and .ldt (EULUMDAT) standard formats as well as UGR glare rating tables.
