An electrodeless HID lamp having a quartz arc tube having a gas fill contained therein, is energized to a discharge state upon the introduction of a high frequency RF current in close proximity thereto, also includes a starting aid stem which extends from the arc tube. An outer jacket surrounds the arc tube and a portion of the starting aid stem. The outer jacket is pinch sealed at the end from which the starting aid stem extends. This pinch sealing results in the formation of a sealed space between the outer jacket and the arc tube and further allows that, by the gripping of the starting aid stem at the pinch seal region, the arc tube is supported in a fixed non-contacting position within the outer jacket. A sealant material can be applied around the starting aid stem at the pinch seal region to prevent leakage of the sealed space formed within the outer jacket.
