Don't forget that regular compact fluorescents don't work with dimmer switches. I did and installed the system with my CFL's still in. When I went to flip the power back on, I was treated to a strobe light show by all the lights now on the new switches.
One thing to note is that these switches are a bit deeper than standard switches. For newer switch boxes this shouldn't be a problem, but I installed these in a 1950's ranch house and the older boxes are quite a bit smaller. This made for a very tight fit for all the individual switches, and for the one double gang switch I had to replace, they did not fit side by side. I had to call in an electrician for help on that one.
Overall, the AuroRa is a really great system if you are a do it your selfer that wants very basic lighting control. For me, the AuroRa was ideal because our space is open and had exactly 5 switches that we wanted to control. By having the master control at my bedside, a simple push of the button turns off all the lights in our main living area and entrance way without having to leave the comfort of warm bedsheets.
If you have more than 5 switches that need lighting control, another AuroRa system will need to be added since each control is limited to 5 switches. Also, even though communication between controls and light switches is via RF, it is proprietary to Lutron and cannot be controlled by a universal RF remote like the Logitech Harmony 1000 which means a few more remotes in the house.
