In a lighting device, when determining that both of a first measuring value and a second measuring value are not an abnormal value, a controller is configured to control an output of a power converter based on the first and second measuring values. The first measuring value is a temperature inside a main body of the lighting device, sensed by a first temperature sensor. The second measuring value is a temperature of a light source, sensed by a second temperature sensor. When determining that at least one of the first and second measuring values is the abnormal value, the controller is configured to control the output of the power converter to another value that is different from a value of the output set based on the first and second measuring values.
