Solatube Ø 74 cm system collector with double dome

Solatube Ø 74 cm series is a line of modular, high output tubular daylighting devices that deliver massive amounts of daylight to large volume spaces with high, open ceilings.

The Collector makes it possible to capture significantly more daylight than traditional skylights without heating the building interior. Featuring proprietary Raybender HD, LightTracker and INFRAREDuction Technology, the vertical collector:

  • Maximizes daylight delivery by capturing and redirecting low-angle light downward into the system 
  • Minimizes solar heat gain by preventing heat-carrying infrared rays from entering the system 

Applications

  • Airports
  • Convention Centers
  • Hospitality
  • Warehouse & Industrial
  • Retail
  • Military
