1. An inductively powered lamp assembly comprising:

  • an inductive secondary to receive power from an inductive primary, the inductive primary having a reactance;

    a lamp disposed in series with the inductive secondary, the lamp having an impedance; and

    a capacitor disposed in series with the inductive secondary and the lamp, the capacitor selected to have a reactance that is substantially equal to or slightly less than the sum of the impedance of the lamp and the reactance of the inductive secondary, whereby the capacitor, the lamp and the inductive secondary operate substantially at resonance.
