A light fitting system has a light fitting for recessed mounting of a luminaire in a substrate such as a ceiling, which fitting comprises a luminaire support and a base for receiving the luminaire support and in relation to which base the luminaire support may be manipulated or moved or directed, and a tool for manipulating the luminaire support. The luminaire support and the luminaire support tool are configured for cooperative inter-engagement whereby the tool may be releasably inter-engaged with the luminaire support to enable manipulation of the luminaire support in relation to the base providing the advantage of a readily adaptable or manipulated luminaire support angularly adjustable or removable by means of the luminaire support tool thereby enabling adjustment and/or removal and replacement of a luminaire from a base without dismantling the fitting from the substrate into which it is mounted.
