Photometric measurements

Photometric measurements of lighting fixtures allow to determine lighting parameters such as light flux, distribution curve, photometric mass, lighting angle, UGR, light efficiency and lighting fixture efficiency. Photometry is performed on the basis of PN-EN 13032 standard, in a specialized photometric darkroom, and the result of measurements is presented in the form of LDT or IES files designed to design lighting in programs such as DiaLux, Relux.

Street lighting

Measurements of street lighting

Road luminance measurements are taken to control lighting conditions, which is a key factor in maintaining high standards. Meeting the lighting criteria, strictly defined in the PN-EN 13201 standard, translates directly into the comfort and safety of drivers and pedestrians using the roads. Measurements of luminance should be performed directly after the road lighting installation and cyclically during operation, which allows to verify the maintenance of the assumed lighting parameters.
