This Master’s thesis is to delineate a luminaire design which has a flexible functional form, can be controlled by the user, and which creates multidirectional light distribution within an indoor space.  A lighting solution with varied light distributions can change a space’s different spatial experiences, granting a flexibility which is controlled by the user to direct light rays into walls, floors, ceilings or to create variations of these. A flexible luminaire in terms of light distribution allows, vertical and horizontal surfaces to be valued equally, because through a minimal intervention it is possible to shift the focus from one surface to another, providing a holistic interplay in space. The participants, who took part in the evaluation program of the final luminaire, freely introduced their possible activities in the predefined dining room, with different lighting proposals according to personal preferences of spatial experience. The designed luminaire was the only accessible tool to influence the space, and they managed to achieve their ideal atmospheres, and experiences, by the process of adjusting the luminaire with controlled light distribution. The varied results of the patterns of brightness and darkness on the vertical and horizontal surfaces in the predefined real space, prove the flexibility of the final design of the luminaire, MM Lamp. The luminaire fulfills the predefined design objectives of being user adjustable as well as creating varied light distribution.
