LightCube is a prismatic skylight that provides the maximum level of light transmission while providing 100% diffusion for glare-free, energy-free cool natural light into a building. Coupled with lighting controls, this daylighting solution helps to illuminate office and retail environments. With no moving parts, LightCube eliminates maintenance concerns and seamlessly integrates into traditional T-Bar grid ceilings. It also allows for electric lights to be turned off for an average of 8 hours a day, over 3,000 hours annually.
