In all my real estate experience, I've only had one buyer who proclaimed with glee, "Oh, I love it. It is SOOO dark in here." I almost fell out, but it goes to show that there's something for everyone.  

Most buyers can't quite put a finger on what it is that they like or don't like about a home, but it often has to do with natural lighting. Whether you're selling your home or improving the one you've got, a sun tunnel may be just what you're looking for.

If you have a place in your home where you can't see what you're doing without turning on a light, that's the perfect place for a light tube. It has a little dome on your roof that isn't prone to leaking like conventional skylights, and the light bounces through a mirrored tunnel into your room. The ceiling fixture has a diffuser so it looks like a regular flush-mount light. You can even get models with a light bulb inside so you get light in the same spot day or night.

Tubular skylights are easy to install, and you can get them at most hardware stores or order online. I even saw some on eBay. Depending on how long your tunnel needs to be, you can complete this project from $300 to $500 for a typical installation. 

It's a very green way to improve your lifestyle!
