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.
