Black and Decker Freewire Wireless Home Control
I just installed this system to control 7 different lights in my house. Some of the lights were inconvenient to turn on and off by hand because of where the switches are. It was very easy to set up the system. It supports creating 2 different "groups" that control several lights at the same time. For example, with one button press I can turn on the right set of lights for watching a movie. There is also a "house off" button that turns off all the lights with one press, and the remote can be wall mounted.
