Protective lighting is used typically in prep areas, refrigerators, freezers and dining rooms. Many businesses are required to use light bulbs coated in plastic whereas if a bulb were to break, glass and chemicals are contained. Protected light bulbs prevent injury to workers and customers. Staff workers never have to touch shards of broken glass if the lighting is protected. In addition, if a bulb breaks in the kitchen or dining room, there’s no worry about it contaminating food. Protective lighting also features bulbs that are able to filter out types of light and radiation that can diminish the flavor and appearance of foods.
