1. A light engine having a driver interface, wherein the light engine is configured to be driven by a driver via the driver interface, the light engine comprising:
a circuit comprising at least one light-emitting diode (LED) strand comprising at least one LED;
a first control unit comprising a first memory unit configured for storing a maximum allowable current value for the light engine, the maximum allowable current value corresponding to a peak electric current at which the light engine operates normally; and
a first digital interface configured for at least one of receiving data and sending data, wherein the first control unit is configured to output the maximum allowable current value stored in the first memory unit via the first digital interface for configuring the driver so that an electric current provided by the driver does not exceed the maximum allowable current value of the light engine.
