Abstract: Low pressure gas discharge lamp comprises a gas discharge vessel containing a gas filling of a group IV chalcogenide and a buffer gas; inner (2) and outer electrodes; and devices for producing and maintaining a low pressure gas discharge. Preferred Features: The chalcogenide is a sulfide, selenide or telluride. The group IV element is silicon, germanium, tin or lead. The chalcogenide is especially silicon sulfide, germanium sulfide, germanium selenide, germanium telluride, tin sulfide, tin selenide or tin telluride. The gas discharge vessel has a luminescent coating (4) on its external surface or on its internal surface.
