A light fitting for recessed mounting of a luminaire 100 on a substrate comprises a base 20 having a longitudinal axis X-X, a luminaire support 30, and an adjustable coupling mechanism to adjust the position of the luminaire support 30 in relation to the base 20 along the longitudinal axis. The adjustable coupling mechanism is operable by way of manipulation of the luminaire support 30 to couple or decouple the luminaire support from the base 20. The adjustable coupling mechanism comprises a tooth arrangement 60-66 on the luminaire support 30 engageable with a tooth engagement means 52a-52e on the base 20. The adjustable coupling mechanism enables the luminaire support 30 to occupy at least two different positions along the longitudinal axis X-X of the base 20. |
