The SolaMaster® Series Solatube® 330 DS-C 530 mm diameter tubular daylighting system pipes daylight from a dome on the rooftop via highly reflective tubing to a square ceiling diffuser in an internal space or room with a closed ceiling, such as office, retail, superstore or school.

An injection moulded impact-resistant polycarbonate roof dome, TP(a) rated with light enhancing dome technology, fits onto a roof flashing upstand attached to a 99.7% reflective, rigid aluminium tube directing natural light to a double glazed ceiling diffuser. The tube assemblies at the roof and ceiling locations incorporate adjustable angle sections to allow the tube direction to be changed in order to avoid obstacles or accommodate the ceiling diffuser location. A patented transition box seamlessly converts the round tubing into a square diffuser which fits into standard ceiling grids (600 x 600 mm).

The SolaMaster® Series Solatube® 330 DS-C tubular daylighting systems are designed to pipe daylight into commercial applications, thus enhancing working and living environments, and reducing energy costs by enabling artificial lights to be switched off during daylight hours. Typically used in larger rooms and open plan work spaces such as offices, hospitals, schools, and commercial buildings.
