Various embodiments are directed to a method of manufacturing a lighting device. In one example, the method comprises providing a glass envelope having one or more openings, inserting a first device component through one of the one or more openings, and providing at least one of the one or more openings with a glass cap by way of melt-joining. Prior to melt-joining the first device component is moved to a position within the glass envelope away from the at least one of the one or more openings. The first device component is repositioned and/or expanded within the glass envelope after melt-joining.
