Incandescent light bulbs were once considered industry standard - the kind that pops into mind when one pictures a "light bulb." They mostly see residential household use, though they often find their way into restaurants, hotels, and other sectors of hospitality where warm light is appropriate for relaxed, intimate settings. Because they use more energy than modern alternatives, incandescent bulbs generally are more expensive to run, and produce more heat in the areas they illuminate.
