Sunoptics 5’0” x 6’0” Signature Series Double Glazed units using Impact Modified Clear Prismatic Acrylic over High White Prismatic Acrylic are used to daylight over 2,000 Wal-Mart Supercenters worldwide. Wal-Mart officials have documented that at 1.2 watts per square foot of light energy, and an average of 2,800 hours a year of turning lights off, one 5' x 6' Sunoptics Prismatic Skylight has the energy saving capability of 2 kW of Solar Photovoltaic Panels for a fraction of the cost and space needed. Today, Sunoptics Prismatic Skylights is the sole specified product for Wal-Mart's daylight harvesting program.
During the early stages of construction, no electric lights are needed inside the building which otherwise would require many electrical cords strewn throughout the site to perform the required work.
With the skylights installed, light levels average just over 100 foot candles throughout the building.
