Wall sconces and wall lights have an advantage in their fixed location. Their disadvantage is that they may complicate any potential changes in internal furnishing. Wall-mounted lights are suitable in places where the interior design is made as a long-term solution and there are no expectations of changes in utilization of the walls. The wall lights are more frequent in restaurants to illuminate the tables. Wall-mounted fixtures in apartments are often located on sides of a large picture or mirror, sometimes they are located on sides around the door in palace's constructions.
