Lighting is extremely important to setting the desired ambiance of any setting, whether for entertainment, romance, or functional work area lighting. Lighting is also a safety feature as in lighting a path to a dark house after sundown. Lighting control can conserve energy and be a convenience feature when programmed to darken the entire house at the press of a single button, either at bedtime or when leaving the house. Lighting control can also be a deterrent to crime by automatically turning lights on/off to give a house a lived-in look even when no one is at home.
