[origin: EP0887841A2] The lamp has a ceramics gas discharge envelope of aluminium oxide, with 2 opposite ends fitted with ceramics end seals, each incorporating an elongate capillary tube, through which a respective 2-part conductor lead (9) is fitted. The inner part (14) of each conductor lead is provided by a pin of a halogenide-resistant metal, e.g. wolfram, with a maximum diameter of 0.4 mm, enclosed by a ceramics mantle (20, 21), the outer part (13) sealed to the end seal via a glass solder (18) over a length of at least 1 mm.
