Solar tubes, also called light tubes, tubular skylights, and sun tunnels (among other nicknames), are cylinders that are mirrored on their internal faces and used to reflect sunlight. They are designed to be installed in the roof. When sunlight strikes the inside face of the top end of the cylinder, the light is reflected and bounces down into the building. A solar tube will of course only work when the sun is shining, or at least in daylight, but it does mean that you can work in a loft, basement, or windowless room without needing lights on all the time.
