Founded in 1978, Sunoptics Prismatic Skylights is a worldwide leader in high-performance daylighting. Our mission is to harness the power of the sun to maximize the cost-effective energy savings of daylighting.
In 2011, Sunoptics joined forces with Acuity Brands to combine daylighting, electric luminaires and advanced lighting controls to offer the industry's most complete set of sustainable and energy-efficient lighting solutions.
For a number of years, Sunoptics and Acuity Brand's Lighting Controls and Design products have been available in an integrated solution that enhances the value of prismatic skylighting solutions.
Sunoptics leverages unique design, materials and construction to optimize lighting performance through prismatic lenses. These lenses provide maximum 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. This provides us the ability to control the light transmission capability of our plastics while maintaining the highest level of product quality in the industry. No other skylight manufacturer has this capability. Our state-of-the-art Photometric Lab as well as a multitude of third party testing confirms real-world performance of all our products.
Sunoptics High Performance Prismatic Skylights have been installed in several hundred million square feet of buildings worldwide. These skylights have the potential of replacing over 500 megawatts of electrical lighting energy during a utilities' peak load hours. According to a recent study by Heschong Mahone Group, Inc., a leading expert in daylighting engineering and design, if the U.S. retrofitted all existing buildings that it makes sense to daylight, the potential peak load reduction would equal 20,000 megawatts. That's like replacing the energy produced by more than 40 coal fire energy plants.
