Customer Reviews

Spectrum 21 in. Tubular Skylight with 12 ft. Flex Tube and Ceiling Lens is rated 3.5 out of 5 by 2.
Rated 4 out of 5 by from Nice skylight Nice light, but there was no instructions for the ceiling mount. It would have been great if it had come with those instructions.

Rated 3 out of 5 by from Decent This thing was very easy to install. I am dinging it due to quality. The locking mechanism for the tube to the top/skylight is sketchy. It has a twist lock style connection. I'd prefer something that is a little more permanent. Also, the skylight top is made of plastic. It started to show wear (scratches) within days of being installed.
