When planning according to EN 13201:2015, you must add details with regard to the number of operating hours of the luminaire arrangement.
Click again on the small triangle on the right. Here you can enter the time periods and the related dimming values for the luminous flux.
Via "+" you can add a further time period. This input only appears in the standard EN 13201:2015 because here it is necessary to calculate the energy parameters of a lighting installation.
