A single use, sealed underwater light fitting which can be replaced quickly and easily, but which is relatively cheap to manufacture, comprises a housing (1), two bulbs (14) and a power supply cable (6). The housing comprises a front cover (7) and a rear cover (8) sealingly connected to each other. The front cover (7) comprises a light transmissive lens portion (10) and an integral surrounding flange portion (11) which is provided with bolt holes (12) for releasably mounting the light fitting into a niche (2) provided in a wall or other surface. The rear cover (8) has an entry means (33) with a watertight seal (32) for the power supply cable (6) to enter the housing. The power supply cable has a wet-mateable connection (5) at its end which extends outside the housing. The light fitting has two bulbs (14), so that it does not need to be replaced immediately after the failure of one bulb. The light fitting is replaced simply by removing the bolts from the flange portion (11) and then disconnecting the wet-mateable connection (5). |
