In most cases no, you won’t have to. The NuBryte is a standalone product and works with incandescent, halogen, and dimmable CFL and dimmable LED lights.
If you have non-dimmable CFL or non-dimmable LED's, they will need to be replaced as these are not supported.
Note that if your prefer not to use the dimming function, you can press the X button when asked "Are Your Bulbs Dimmable" during the initial setup (or at any time from Menu > Settings > Wizard) but even in this case if you are using a CFL or LED bulb, it still must be rated dimmable.
