The optical fibers end in hybrid luminaires where the sunlight is joined with electric light, either on demand or to automatically maintain a constant light level even as the available sunlight decreases.〔Maxey, Curt. "Fiber Optics Brings Sunlight Inside." Hybrid Solar Lighting: 1.Photonics.com. Web. 15 Oct. 2009..〕 ==Method of operation== Solar lighting systems capture light from the sun and conduct it towards a room using optical fibers. They use rooftop collectors, large mirrored dishes, that track the sun. The collectors adjust to aim the sunlight onto 127 optical fibers which are conducted into a single chord. The optical fibers are flexible and can be connected into hybrid light fixtures that are joined to diffusing rods that disperse the light. A single collector can power up to eight hybrid light fixtures covering . The hybrid lights also use artificial lighting which is mixed with the natural sunlight beamed in down the fiber optic chord. Photosensors focus on how much light needs to be generated to add to the natural light in order to keep a room illuminated at a constant brightness. When the sun is blocked by clouds around five percent of its sunlight requirement will need to be added. Hybrid solar lighting systems should be used in rooms with direct roof access.〔Schirber, Michael. "Hybrid Solar Lighting May Be Next Big Thing."
