Abstract

To reliably support a metal halide discharge vessel within an outer bulb, spite of possible shock or vibration, and to accomodate thermal expansion in use, a support structure (6) is provided, melt-connected to the base (4) and having a cross bar portion (15) positioned transversely to the lamp axis of a length substantially less than the diameter of the outer bulb (1), and electrically and mechanically connected to one of the current supply leads (11) of the discharge vessel. The cross bar portion is connected through respectively inclined connecting portions (16, 17; 16', 17') to transversely extending first and second holding portions (20, 21; 20', 21') located within the outer bulb, and extending in chord across the outer bulb at respectively opposite sides of the discharge vessel.
