Since 1986, Solatube International has been harnessing the power of natural sunlight to brighten the interiors of buildings where people live and work with tubular daylighting systems. Unlike traditional skylights, Solatube Daylighting Systems use advanced optics and breakthrough delivery technologies to illuminate previously unreachable areas like corners, closets, and rooms on lower floors.

This is the ideal solution for increasing natural light in a cost-effective, energy-efficient, and eco-friendly way as these systems can reduce the demand for electricity while keeping occupants connected to the outside environment and with natural daylight. Available for commercial spaces, federal tax credits for builders may apply.
