Light tunnel with flexible light transmitting tube SLT

Flexible Light Tunnel SLT


Flexible light tunnels SLT are a great way to brighten up small spaces and dimly lit rooms. Areas such as corridors, hallways and bathrooms benefit from the light from a tunnel especially since they often are too small or centrally located making it impractical to install windows.

The sun’s rays are reflected off the walls of the flexible tube on to the light diffuser fitted into an internal ceiling. The diffuser spreads the light, evenly lighting the whole inside of the room. Thanks to the light tunnel, natural light can now be used throughout a building enhancing the user’s comfort, and saving electricity. The light tunnel may also be used at night by installing a light kit.
