Abstract: A lighting device and corresponding method are described herein. In various aspects, the lighting device may be implemented as an electrically powered lighting device (e.g., a C5W lamp). The lighting device may include a first electrical supply contact and a second electrical supply contact. The lighting device may also include one or more light emitting diodes disposed between a first terminal and a second terminal, such that the light emitting diode(s) may be conductive from the first terminal towards the second terminal. The lighting device may further include a rectifier circuit that contains first and second rectifier branches being conductive from the first supply contact towards the first terminal and from the second terminal towards the second supply contact, respectively; and third and fourth rectifier branches being conductive from the second supply contact towards the first terminal and from the second terminal towards the first supply contact, respectively.
