The subject of sun tubes or solar tube skylights keeps coming up in email exchanges with readers, because they’re often more efficient than conventional skylights. There are numerous competing brands and designs, but the basic concept is a skylight that directs light through a mirrored tube. Some designs like the Solatube skylight pictured above bend around obstacles. Some have flexible pipe, and some have one skylight with multiple tubes that direct light to different rooms.
Go to Google Images and search for “sun tube skylight” and you’ll see lots of options. This is a great way to add extra light to areas where windows are not practical.
