Abstract

An LED replacement lamp compatible with a ballast of a high-pressure Sodium lamp and a ballast of a mercury vapor lamp, the LED replacement lamp comprising, input connections for receiving a voltage from a ballast, a rectifier circuit (D1, D2, D3, D4) for rectifying the received voltage into a DC voltage, a shunt switch (M1) arranged for regulating power to an LED load (LED), the shunt switch being coupled between output connections of the rectifier circuit output connections for connecting to the LED load a sensing circuit for sensing a parameter of the received voltage or the rectified voltage, wherein upon sensing of activation of an ignitor of the mercury vapor ballast, the shunt switch is operated such that a root mean square voltage at the input connection is reduced such that the ignitor turns off.
