<p>The present invention relates to a lighting unit 42 comprising a recessed female structure 4 secured to and defining an aperture in a partition 14, and a male housing 3 mounted within the recessed structure. A light emitting element 38 is mounted within the housing and connected through an aperture of the housing to a power source. An intumescent material 32 is mounted in the housing above the light source. Light is emitted through a front side aperture of the housing by the light emitting element. The front may be protected by a water-proofing structure 44. The power source is accessible by separation of the housing from the recessed structure (figs.2A&B).</p> |
