We love the lighting result and would recommend your product to anyone.

Even after seeing it at neighbors, I couldn't believe the difference it made in my house. We love them.

- Ed S.

Great product, I can't believe how much light it brings in. My wife wanted at first to turn it off, but now she loves it!

- Mark W.

We couldn't be happier with our new lighting. The men we dealt with were kind and honest. Our installer was very capable and quick. I was surprised that he cleaned up, too!

- Rebecca B.

Really brightens the rooms, a great product, should cut our electric bill.

- Daniel M.


Immediately upon installation we were extremely impressed with the results. A once almost dreary interior room has been transformed into a bright, welcoming one.

- Paul F.

I love the amount of light solatube adds to my once dark and dreary bathroom. It also lightens up the hallway that leads to the bathroom.
