At all times while any alcoholic liquor licensed premises is open for business, the interior lighting therein shall be sufficient to make easily discernible upon immediately entering the main entrance the appearance and conduct of all persons and patrons in that portion of the premises where alcoholic liquors are sold, served, delivered or consumed. In no event shall the intensity of the interior lighting be less than one foot-candle power light when measured to a point thirty inches (30") from the floor whenever persons and patrons are sitting or standing within the premises. This requirement shall apply in all cases except in licensed establishments where floorshows are permitted under city ordinance. In such cases, the floor showroom lights only may be dimmed during the floorshow, and at the conclusion of each floorshow, the lighting must then immediately be restored to the minimum standards of light intensity prescribed.
