Abstract
A lamp comprises an input for connection to a high frequency ballast for gas discharge lamps. A power supply unit obtains power from a LED on voltage of the LED of the lamp, and the power supply unit powers an isolation switch at the input. During a preheat stage of the ballast, the power supply unit does not close the isolation switch, but the isolation switch is closed when the high frequency ballast is in a later state, i.e. the ignition phase.
