A lighting control program update system includes a wireless operation device, a plurality of lighting devices, and an update device. The wireless operation device outputs an operation instruction including first wireless operation device ID information. When the first wireless operation device ID information included in the operation instruction matches second wireless operation device ID information stored in the lighting devices, the lighting devices perform an operation in response to the operation instruction. The update device broadcasts a control program update instruction including third wireless operation device ID information that is identical to the first wireless operation device ID information to the lighting devices. When the third wireless operation device ID information matches the second wireless operation device ID information stored in the lighting devices, the lighting devices update a control program stored in response to the control program update instruction.
