Techniques and user interfaces (UIs) are disclosed for controlling a solid-state luminaire (100) having an electronically adjustable light beam distribution. The disclosed UI may be configured, in accordance with some embodiments, to provide a user with the ability to control, by wireless and/or wired connection, the light distribution of an associated solid-state luminaire (100) in a given space. The UI may be hosted by any computing device (300), portable or otherwise, and may be used to control any given light distribution capability provided by a paired luminaire (100). In accordance with some embodiments, the user may provide such control without need to know details about the luminaire (100), such as the quantity of solid-state lamps, or their individual addresses, or the address of the fixture itself. In some cases, the disclosed techniques may involve acquiring spatial information of the space that hosts the luminaire (100) and/or providing user-selected distribution of light within that space.
