For more expansive areas and higher light levels, choose a 21-C or 21-O Solatube Daylighting System. Our patented transition box converts the round tubing to a 24" (600mm x 600mm) square diffuser, allowing easy installation in suspended ceilings as well as hard ceiling applications.

The Brightest Idea in Daylighting Expansive spaces require extraordinary amounts of natural light so we designed the SolaMaster Series.
