The Firestone SunWave Daylighting System features a double-glazed, acrylic, prismatic layered dome that provides high visible light transmittance with wide light distribution. The system has more than 4,000 tiny prisms per square foot to refract, direct, and diffuse sunlight into thousands of tiny beams, decreasing the need for indoor electrical lighting by up to 70%. It catches up to 20% more light at low angles than standard shapes and transmits light to a work area without producing glare or hot spots or causing UV damage. SunWave is available in six standard sizes: 2' by 2 ', 4' by 4', 4' by 8', 5' by 5', 5' by 6', and 5' by 8'.
