 What options do you have in skylights? Because I've always known the long square ones. I've seen those on people's homes before. But you were telling me that there's an easier option if somebody wants to add some natural light in a room that didn't have it. Like a bathroom would be a great place. You'll get a little moonlight action in there as well or in like a living room. Where do people mainly get the lights? And tell me about the tube lights because sun tunnels. Tell me about that. I've never heard of that earlier than just five minutes ago.
