I own a solar tube business and will recommend the 290 which is 14 inches in diameter for both rooms. Also, with the solar night light there is a 26% Federal tax credit on all materials and labor. The IRS forms are supplied by the vendor. They do not leak as the same principle flashing system is used as a plumbing boot for your stack pipes. Plumbing boots are more prone to leak as they are rubber and the UV rays deteriorate them, whereas the solar tubes use a metal flashing. I recommend the Solar Guys as they’ve been in business for many years as others have come and gone. The payback is not 30 years, but the benefits are instant. I have 5 here in my home in The Villages. My business is in Atlanta so I can’t help you.
