The reflector 104 may have any desired colour. For example, the reflector 104 may be white, silver or gold. A front bezel 315 may be selected to aesthetically complement the reflector 104. The reflector may comprise any suitable material or materials, and may have any suitable dimensions, shape and surface pattern. It is to be appreciated therefore that the present invention is not limited to the specific reflector shown in the Figures. According to the specific illustrated embodiment, the fixing ring 309 can be seen inside the reflector 104. In other words, the fixing ring 309 is visible within the reflector 104, by looking through the lower end 3 13 of the reflector 104. Therefore, the fixing ring 309, while serving a functional purpose, may also advantageously be used for visual effect. A fixing ring 309 may be selected to aesthetically complement the reflector 104. The fixing ring 309 may comprise any suitable material or combination of materials. In an example, the reflector 104 and the fixing ring 309 are aesthetically complementary. In an example, the reflector 104, the fixing ring 309 and the front bezel 315 are aesthetically complementary. The downlight 101 may have any suitable dimensions and may comprise any material or combination of materials. Preferably, and according to the specific illustrated embodiment, the downlight 101 is a fire rated downlight. The downlight 101 may have been 30-, 60- or 90-minute fire rated. In a specific example, the housing 103 comprises steel, and the fixing projections 403 of the first two-part coupling arrangement for releasably securing the LED lighting module 102 and the housing 103 comprise stainless steel. The central aperture 602 of the housing 103 is substantially blocked by the central connector element 601 of the LED lighting module 102 and each fixing aperture 404 is substantially blocked by a fixing projection 403 and surrounding material of the LED lighting module 102. Thus, openings through the housing 103 are substantially filled, minimising the presence of gaps through which flames can penetrate. According to the specific illustrated embodiment, the downlight 101 incorporates a watertight LED lighting module 102. The present invention therefore provides a downlight that is assemblable using only mechanical engagement of components and that incorporates water- and fire- resistance. Although illustrative embodiments and examples of the invention have been disclosed in detail herein, with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiment and examples shown and / or described and that various changes and modifications can be effected therein by one skilled in the art without departing from the scope of the invention as defined by the appended claims.
