Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye.
Our luminaires are tested using rotating mirror photometers, which keep the luminaire stationary at a sufficient distance from the photocell that the luminaire can be considered a point source. Rotating mirror photometers use a motorized system and a mirror that directs light radiated from the luminaire in all directions to the distant photocell. From the photometric data it is possible to produce light
technical data according to utilized standards and applications.
The data serve as basis for lighting calculation programs in which
entire rooms, fitted with diverse luminaires, are calculated and
evaluated, exact illumination design plans can be produced.
All photometry is executed according to the EN13032-1 and CIEs (International Lighting Commission) regulations and guidelines.
