Fill the room with healthy, natural light. And save energy, which will also save you money! The Daylite Tube is a highly reflective, cylindrical skylight, that runs from the roof down into a room providing the illuminance of full spectrum lighting. Sunlight enters the tube through a clear acrylic dome. The inner prismatic lens (fly-eye) captures the light from all angles and collimates it down the reflective tube, to be evenly spread through out the room via a second prismatic diffuser lens. On sunny days, the Daylite Tube can provide the equivalence of 738 Watts of incandescent light. Even on cloudy days, the Daylite Tube can provide 100 to 180 watts of illuminance.
