Abstract
Devices (1) for producing light comprise inputs (11) for receiving feeding signals via ballasts (2) designed for fluorescent tubes to be replaced by non-fluorescent tubes, drivers (12) for driving light circuits (13), first receivers (14) for receiving definition signals defining features of the ballasts (2), and controllers (15) for, in response to receptions of the definition signals, adapting functions of the devices (1). The functions may comprise reporting functions, whereby apparatuses (3) are informed by the devices (1) about amounts of consumed power of the devices (1) and amounts of consumed power of the ballasts (2). Then, for example in dimming situations, overviews of total amounts of consumed power are realized. The functions may comprise driving functions whereby the light circuits (13) are driven in accordance with requirement data of the ballasts (2). Then, for example in dimming situations, first dimming levels may be forbidden and second dimming levels may be allowed.
