ABSTRACT:
An electrodeless lamp is started by coupling microwave power of a first frequency to a lamp cavity, while the discharge is maintained by coupling microwave power of a second frequency, wherein the first frequency is lower than the second frequency. A cooling fluid is impinged on the lamp bulb immediately before the application of the microwave power of the first frequency.
