| 1. A flash lamp (10) comprising a gas-filled discharge tube (11) made of glass and, at each end, a power electrode (14, 15),
characterized in that
a glass is used which with a thickness of 0.5 mm has one or more of the following transmission parameters Tw:
at 180 nm: Tw>5%, preferably >9%
at 200 nm: Tw>30%, preferably >45%,
at 254 nm: Tw>60%, preferably >80%,
and further characterized in that
at least one power electrode (14, 15) is connected with the discharge tube by means of glass solder (13a, 13b), the glass solder having a softening point and/or a transformation point which is at least 60° C. below the respective one
of the glass of discharge tube (11).
