The U.S. Sunlight spectrum series of skylight tubes offer an industry first for light tunnels - a ventilation option. With simple snap-on, snap-off installation, convert your spectrum skylight tube in to a passive ventilator. This simple addition makes the spectrum series an even better choice for restrooms, kitchens, garages, laundry rooms and any place where day lighting and ventilation are desired. Simply install utilizing the ventilation tabs on the roof dome and install or remove the ceiling ventilation hardware to convert to passive ventilation or revert back to energy efficiency. Additionally, designed with your home’s aesthetic appearance in mind, install your new tubular skylight on either the front or backside of your house. Simple installation, hail-resistant dome and engineered for a leak-proof installation - the spectrum skylight tube is the perfect option to add natural light in your home.

  • Captures light above your roof and tunnels it to just about any location in your house with the larger 18 in. roof dome
  • Impact-resistant roof lens - hail resistant and capable of carrying a live load of over 260 lbs.

  • Single piece flashing - 1-piece sleek roof lens flashing blends with any roof type, allows for leak-proof installations and is a visually stunning improvement over traditional dome-shaped tube lights

Rated 4.5 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Works fine, easy to install. The flexible tubing made this an EZ install. The skylights with the stiff metal tubing can limit where you put the skylight. Down side about the flexible tubing is it doen't transfer as much light as the stiff metal tubing, but it definately was easier to install. I plan to purchase another one for our kitchen.

Rated 5.0 out of 5.0 by The design is excellent! This has got to be one of the best thought out designs I have seen in a while. It is easy to install yet simple & well built. The design also allows easy service as well. I tried it out & liked it so well I bought another for a different room. December 17, 2013
