1. An arrangement comprising:

  • a source providing a power line voltage between a first and a second power line terminal;

    a power track having a first and a second track conductor;

    the power track being operative to receive and hold a number of track lighting units;

    each one track lighting unit having a pair of load terminals;

    which load terminals, when the one track lighting unit has been received and is indeed being held by the power track, make electrical connection with the track conductors; and

    voltage conditioner means connected in circuit between the power line terminals and the track conductors;

    the voltage conditioner means being operative to convert the power line voltage provided between the power line terminals to a track voltage provided betweeen the track conductors;

    there being, through the voltage conditioner means, an electrical conduction path between the first track conductor and one of the power line terminals;

    the fundamental frequency of the track voltage being substantially higher than that of the power line voltage.
