Abstract

A high-pressure gas discharge lamp provided with a gas filling which comprises at least 10<->7 gram atoms of germanium per cubic cm of the discharge vessel and selenium. The selenium-germanium ratio has a value of between 0.5 and 4. Furthermore the gas filling may comprise tin and a halogen in which the selenium-halogen ratio is chosen between 0.02 and 4. In addition to the said elements the lamp preferably includes a starter gas (rare gas) and a buffer gas (mercury). The lamp emits the continuous molecular radiation of germanium selenide and a very satisfactory colour rendition is possible in a wide range of colour temperature.
