I'm trying to find information on somethign I've seen on the telly a few times. They're cylindrical tubes, mirrored on the inside, the top pokes through the roof, with a plastic clear dome to stop water getting in, and the bottom looks like one of those halogen flush lights, except much bigger (6-10 inches diameter).
They're basically used to get more light into a dark room, the trouble is I can't find any more information on them! Anyone got any ideas?
