Today Jan and I installed some sun tubes upstairs. The one in the picture on the left will light up our closet area. The one on the right I will be extending through our bathroom down to the first floor to light up the entrance from the garage.

This is the one in our bedroom.
This one will continue through to downstairs. They are very bright (approx 3 - 100 watt bulbs)
This is what they look like on the roof. I hated cutting a hole in our new roof!
