FAKRO light tunnels enable illumination of all rooms in the building, even those which cannot be fitted with roof windows or vertical windows. Using the FAKRO light tunnels in a room devoid of daylight lets natural light inside for better illumination. In other rooms, the light tunnel can constitute an additional light source, enhancing the users comfort and saving energy. It carries daylight via the light transmitting tube. Sunlight is reflected from the walls of the flexible, reflective tube and is directed downwards to the diffuser. The diffuser which is fitted in the ceiling evenly distributes natural light, illuminating the room. FAKRO SLC Hanger Features Used when an overall light transmitting tube is longer than 5m. Hangers are applied to take part of the tubes weight and to prevent it from tearing away from the light tunnel flashing.
