Efficiency and declaration requirements exist for various lamps, and in some cases for their control mechanisms and luminaires.
In the legal documentation of the EU, the term "lamp" refers exclusively to the light source. The SFOE has adopted this usage, even though in Switzerland the term is used to refer to both the light source (e.g. energy-efficient lamp) and the device itself (e.g. table lamp).
The Swiss Federal Energy Ordinance stipulates that lamps and luminaires must be declared using the energy label. For lamps, in addition to the energy efficiency category, the label also indicates the power consumption per 1000 operating hours, and for luminaires, with which energy efficiency category of the light bulbs and other illuminants the luminaire is compatible.
