An incandescent lamp with a low voltage burner (BM) and integrated voltage conversion means (VCM) having switching elements (Q1, Q2) driven by a separate control circuit (CC) comprising an integrated circuit (IC). The voltage conversion means are suitable for operation at a high temperature and causes only limited amounts of EMI.
