Beschreibung
Zusammenfassung:	A lamp for use in subterranean galleries such as mines in which the cold-cathode discharge tube is received in a housing which, in turn, is removably mounted in a receptacle and is held in place by a ring clamping a flange of the housing against a flange of the receptacle. The housing may be provided with a translucent cover so that the housing can be removed and replaced as a unit. A reed switch on the receptacle cooperates with a magnet on the housing to deenergize the terminals of the housing upon its removal. The terminals of the discharge tube are embedded in an insulating potting mass within the housing.
