I can only comment on Solatube, which is the brand installed by The Solar Guys on 441.
In 1998 when building our house in Wisconsin I wanted more light but didn't want the traditional skylights. I came across an article in a home magazine about a new type of skylight called Solatube. I did some research, got some info, gave it all to my builder and said I want these. He had never seen such a thing and thought I was nuts. He became a believer after he installed them in our house.
I had one put in our home in Duval when we moved to TV, and tomorrow the installer from The Solar Guys is coming to install one in our house in Bonita.
There are several brands available now, but Solatube was the first. You may want to check out their website.

I certainly recommend them. And now if The Solar Guys want to give me a few bucks off my bill tomorrow for the wonderful recommendation, that would be good!
