The task of daylighting large areas in multistory buildings such as open-plan offices and school classrooms poses a challenge to designers who must also illuminate the building core. The horizontal SunCentral lighting system from SunCentral can be integrated in a ceiling canopy or atrium to gather and redirect sunlight captured outside from all roof surfaces. Using a series of luminaire beams, the light can be transmitted it up to 50 feet within a building. The fixture integrates LEDs that dim or brighten to deliver consistent light levels when its photosensors detect a change in available sunlight. The luminaires are available in recessed or pendant models.
