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.
The collectors adjust to aim the sunlight onto 127 optical fibers which are conducted into a single chord.
A single collector can power up to eight hybrid light fixtures covering 1,000 square feet (93 m2).
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.
