Extension tubes can be added in increments of 24 in. (600 mm) to extend tube runs to the desired length without sacrificing performance. Our unique telescoping tubing system allows for easy adjustment in the field so tubing rarely has to be cut. Spectralight® Infinity Tubing has the highest reflectivity in the world making it possible to create extensive tube runs of up to 20 ft. (6 m) for the Solatube 160 DS and up to 30 ft. (9 m) for the Solatube 290 DS.
