Abstract
The present invention provides a low pressure metal halide fluorescent lamp. The metal halide fluorescent lamp may have an oblate spheroid cavity discharge vessel filled with an ionizable metal halide surrounding an exciter housing. An exciter within the exciter housing may drive the ionizable metal halide in an inductively coupled electrode-less manner. One or more embodiments may include one or more heat spreaders and/or thermal transfer pipes for transferring heat from the exciter to a surface of the oblate discharge vessel.
