Techniques are disclosed for identifying and controlling light-based communication (LCom)-enabled luminaires. In some cases, the techniques include a luminaire communicating its ID to a computing device via one or more LCom signals. In some cases, a user may be able to aim a rear-facing camera of a smartphone at the luminaire desired to be controlled. Once the luminaire is in the field of view of the camera, the ID of the luminaire can be determined using one or more LCom signals received from the luminaire. The ID of the luminaire may be, for example, its internet protocol (IP) address or media access control (MAC) address or another unique identifier. Once a luminaire has been identified, commands can be issued to the luminaire to adjust one or more characteristics of the light output, such as changing the dimming percentage of the light output.
