Abstract (en)

The method proposed for the production of a metal-halide discharge lamp with a ceramic discharge tube is characterized in that first both ends (6a, 6b) of the tube are fitted with electrode systems and sealed, a filling bore (15) near the pump end (6a) of the tube remaining open, however, this bore not being closed until after the tube has been filled.
