Light tunnel with rigid light transmitting tube SRT

Rigid Light Tunnel SRT



The rigid light tunnel is an effective method of illuminating 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 inside of the rigid light tunnel’s tube acts much like a mirror, effectively reflecting light through the tube into the space below. The tube’s interior is lined with a silver light-reflective layer illuminating a room with even the highest ceiling, making the SRT rigid light tunnel suitable for almost any type of residential or industrial building.
