1. An electrodeless plasma lamp comprising:

  • a metal enclosure having a conductive boundary forming a resonant structure;

    a radio frequency (RF) feed to couple RF power from an RF power source into the resonant cavity;

    a bulb containing a fill that forms a light emitting plasma when the power is coupled to the fill, the bulb being received at least partially within an opening in the metal enclosure; and

    a controller to modulate the RF power to induce acoustic resonance in the plasma.
