The best way to get light (during the day) is to somehow come up with a structural modification that would not be that much of a pain. Some folks have already done it, adding an opening to their roof or windows, depending on what would not cost that much to integrate.
But if you want something advanced, the Lightscoop Skylights should be something interesting. The solution is something which is adjustable that can fill home interiors with natural lighting and eventually save you a lot as far as your electricity bill is concerned.
The Lighting Research Center (LRC) at the Rensselaer Polytechnic Institute have come up with this magnificent solution, an appended modification which should easily be something conservative home folks are going to be interested in.
The new design allows users to adjust skylights dependent on the weather, while also blocking the costly solar gain that can occur during summer.
