A protected lamp assembly includes a tubular lamp enclosed within a tubular protective housing. The lamp is supported by grommets or bushings of a resilient material that are retained within the housing. An end cap assembly may include the bushing for the lamp and also support the protective housing. Conductors through the end caps communicate with the lamp electrodes. In alternate embodiments the conductors may emerge from one of the end caps or the end caps may include a conductive coating with a connection to the lamp electrodes.
