The invention provides a general illumination luminaire comprising one or more adjustable light modules. In particular, the luminaire generally comprises one or more light modules, each one of which comprising one or more light-emitting elements, and optionally comprising a heat sink in thermal contact therewith and output optics for managing light output from the one or more light emitting elements. In general, the light modules are adjustably coupled to the luminaire via a coupling structure that provides one or more adjustment mechanisms for adjusting the orientation of the light modules for adjusting an output directionality of the luminaire, while substantially maintaining the spatial profile of the luminaire.
