The SkyVault Collector makes it possible to capture significantly more daylight than traditional skylights without heating the building interior. Featuring proprietary Raybender HD, LightTracker and Cool Tube Technologies, the vertical collector:
  • Maximizes daylight delivery by capturing and redirecting low-angle light down ward into the system
  • Minimizes solar heat gain by preventing heat-carrying infrared rays from entering the system


The Solatube M74 DS Amplifier significantly improves the delivery of daylight in high bay and high ceiling applications. Featuring 36 highly reflective facets made of proprietary Spectralight® Infinity material, the cone-shaped amplifier:
  • Reorients daylight to the visual task plane in occupied areas
  • Converts daylight at inefficient angles into useable light for increased optical efficiency of diffuser technologies
