Skylights are the natural light fixture from Sunoptics, America's leader in high-performance Prismatic Daylighting Solutions. Sunoptics Prismatic Skylights single-minded mission is to harness the power of the sun to maximize the cost-effective energy savings of daylighting. Sunoptics optimizes lighting performance through prismatic lenses that provide the maximum amount of light transmittance while maintaining 100% diffusion which eliminates undesirable hot spots, glare and UV damage to the daylighted space.
Sunoptics manufactures all of its own plastic with its state-of-the-art extrusion equipment which provides the ability to control the light transmission capability while maintaining the highest level of product quality in the industry. No other skylight manufacturer has this capability. Sunoptics state-of-the-art Photometric Lab as well as a multitude of third party testing confirms real-world performance of all our products.
