Today, architectural lighting is an integral element of any residential complex, shopping center, business center, cultural heritage sites and even private houses and residences. Without it, any idea of the architect, obvious in daylight, is lost as soon as dusk falls. With the help of the light concept, you can not only create a night look of the building, but introduce a new idea, emphasize the architectural features of the building, as if putting on a new «dress» on the facade. In addition to the decorative component, the lighting of buildings has a functional purpose.
