Abstract

A method and a device for setting a target brightness value of a luminaire are provided, wherein a first brightness value is measured before switching off the luminaire and a second brightness value is measured after switching off the luminaire, and wherein the target brightness value is set on the basis of the first brightness value and the second brightness value. Furthermore, a corresponding luminaire is provided.
