The control device individually controls operations of the two or more lighting devices. Each lighting device includes a light source, a sensor for measuring light intensity of the light source, and a controller circuit for controlling the light source. The control device includes a replacement detector circuit, and the replacement detector circuit determines whether any of the lighting devices has been replaced, and obtains a determination result distinguishing a replacement lighting device from remaining lighting device(s). When the replacement detector circuit has obtained the determination result, the control device controls at least one of the lighting devices based on the measurement value outputted from the sensor of the replacement lighting device and the measurement value(s) outputted from the sensor(s) of the remaining lighting device(s), so that a difference between light intensity of the replacement lighting device and light intensity derived from the remaining lighting device(s) falls within a predetermined range.
