Abstract

A downlighter comprises a casing 1 for housing electrical connections for connecting the downlighter to a source of mains electricity and a downwardly extending electrical contact collar 2 for receiving a bulb, fluorescent tube or other light fitting. A reflector 4 extends downwardly from the casing to a position below the light fitting, and a fabric hood 9 coated or impregnated with a liquid based intumescent material extends downwardly from the underside of the casing around the external wall of the reflector. The hood is connected at its lower end to an annular base of the downlighter and includes a top 11 to which is secured an intumescent gasket 12 formed with an aperture 14 through which the downlighter collar 2 extends with a clearance between the boundary of the aperture and the collar exterior.
