Is the light from prismatic daylight adequate to replace electric lights?
YES. In fact a properly designed daylighted space with Sunoptics Prismatic Skylights have been proven to be able to shut off electric lights for an average of 8 hours a day during the highest cost of energy time of the day. Sunoptics skylights have the highest level of light transmission with 100% diffusion of any other skylight on the market and can replace electric lighting sources for 70 to 80% of the daylight hours.
