Abstract: An electrodeless lamp bulb for producing relatively high radiation output in the deep ultraviolet part of the spectrum when excited with microwave energy wherein the bulb envelope is made of synthetic quartz which is substantially water-free. This results in increased bulb lifetime, since loss of bulb transparency with exposure to deep ultraviolet radiation over time is substantially reduced. An electrodeless lamp incorporating the above-described bulb includes a microwave chamber in which the bulb is situated and means for coupling microwave energy to the chamber.
