SunShine units are leading edge High Performance Skylights (HPS), also called deep-well skylights, and are designed to use sunlight to provide cool, defused light to illuminate building interiors. • A technologically advanced skylight lens captures more light for use indoors from dusk until dawn and on cloudy days, regardless of the season. • A highly-reflective light well directs the sunlight into the building and ensures against undesirable gain or loss of heat. • A diffusion lens, unique to SunShine, disperses the light evenly throughout the building. • An integrated control system using photo sensors adds artificial light (internal or existing external) only as needed to maintain the desired constant light level.. How sunshine units are installed The skylights are well-sealed at the roof penetration. There are no limitations on the building structure, and SunShine units can be installed on any type of roof. On average, a 4 ft x 4 ft SunShine unit covers 800 to 1,200 square feet. Compared to other similar solutions, SunShine provides larger lighting coverage and does not weaken roof structure as there are fewer opening cuts required. The SunShine Daylighting Systems uses reflective components that capture the light, makes it brighter and evenly distributes it to the interior.
