Choose by Lighting Needs
Tubular skylights bring soft natural light into the home. 99% of UV rays are absorbed to protect rugs, furniture, and clothes from fading.
Light output will vary by time of day, roof orientation and shaft length. Tubular skylights are not recommended for heavily shaded roofs.
Below are guidelines to help determine the size and number of skylights for a given space.

Choose by Length Requirements
The standard kit length is 48”. 20” and 48” extension tubes are available to allow the skylight to be installed to longer lengths. The tubes have a highly reflective mirror finish but the maximum amount of light decreases as the length increases.

Angled Tube Installation
Two adjustable tubes can be angled up to 45° to avoid interference with pipes, ducts, wires, etc.
This allows you to locate the diffuser in the best spot on the ceiling. Two adjustable tubes are included with every kit.
