A large screen displays a diagram of concentric rings with text indicating distances in meters, set within a dark room with a ceiling of exposed lighting fixtures. The scene shifts to a wall with the word "lighght" illuminated by a spotlight, then to a man observing two smartphones mounted on a wall, followed by a man posing beside a large framed drawing of waves, then a dark screen showing a car driving on a bridge in a foggy landscape, and finally a man with glasses speaking on a television screen in a dimly lit room.
