Not all areas in a restaurant require the same type of lighting, nor do they require the lights to be on for the same period. The intensity and degree of lighting is also different if one wants to achieve better energy efficiency. Besides replacing the lightbulbs, based on increasing efficiency and to achieve adequate lighting of the space, thereby reducing and op- 140
