DIALux is a free of charge lighting design software application for calculation and visualisation. The program is provided by the Deutsches Institut für Angewandte Lichttechnik (DIAL - German Institute of Applied Lighting Technology). The DIALux software gives a quick and easy quantitative analysis of a design and includes simple 3D and rendering functions. The ULD data format for the luminaires comprises the 3D geometry of the luminaire, the light intensity distribution, and an article description. The plug-in packages of luminaire manufacturers contain additional planning data such as maintenance factors or UGR values.
