<p>A gas discharge lamp has a tubular envelope (1) containing tubular electrodes (30) at opposite ends. An annular support member (40) of a compressible ceramic fibre is supported in a groove (33) around each electrode and is compressed against the inside surface of the envelope. Movement of the electrodes (30) relative to the envelope (1) is damped by the support member (40). <IMAGE></p> |
