Claim:
1. A luminaire which changes illumination state according to a dimming command transmitted on radio waves from a dimming controller, the luminaire comprising: a light source; a wireless communication circuit configured to communicate with the dimming controller; a storage which stores an identifier of the dimming controller; and a control circuit configured to, when the wireless communication circuit receives, while the luminaire is in a paired state with the dimming controller, the dimming command transmitted from the dimming controller, dim light of the light source according to the dimming command received, the paired state being a state in which the identifier of the dimming controller is stored in the storage of the luminaire, wherein the control circuit includes a communication check mode for checking whether or not the luminaire is able to communicate with the dimming controller, and in the communication check mode, the control circuit is further configured to, regardless of whether or not the luminaire is in the paired state with the dimming controller, bring the luminaire into a predetermined illumination state by dimming the light of the light source when the wireless communication circuit receives a communication check command which is for checking communication between the luminaire and the dimming controller and is transmitted from the dimming controller.
