DIALux evo automatically sets the visual task and the surrounding area to a height of 0.8m when creating work areas according to EN12464. The background area, however, is set to a height of 0m.
According to convention, the background area is always on the floor. In the standard, the specification of 0m is not directly formulated. However, this value can be found in numerous documents from manufacturers such as Trilux, Philips, etc., who have actively contributed to the standard.
