Abstract
An electrodeless plasma lamp having a bulb containing a fill that forms a light-emitting plasma is described. The lamp includes a power amplifier to provide radio frequency power to the fill at a frequency in the range of about 50 MHz to 10 GHz and the power amplifier is configured to operate in at least two classes of operation. Control electronics of the lamp is configured to change the class of operation of the power amplifier during operation of the plasma lamp. For example, the power amplifier may be configured to operate as a class A/B amplifier during at least a first mode of operation and a class C amplifier during at least a second mode of operation.
