The lamp includes an inflatable balloon-like enclosure composed of translucent or transparent material. The latch unit is normally at a closed position for blocking the opening. A driven radiating section includes a first top-loading element and a feed conductor that electrically connects the feed point linearly to the first top-loading element, yet with the driven radiating section not electrically connected to a grounding surface. When the volume and the port are not found, the storage management program judges whether an alternative volume for the reserved volume is present using a volume adjustment subprogram. The impinger ruptures a hole in the burst disk of the pressure vessel and the gas in the pressure vessel is able to quickly exit the pressure vessel. The first coupling ring with a first thread is screwed onto one plug contact to be fixed to the plug element while the second coupling ring with a second thread that overlaps the first coupling ring, is screwed onto a mating thread section at the other plug element.
