You can replace up to a four switch panel in your home with a Brilliant, and you can replace dimmable and non-dimmable light switches. Behind your light switch, you will find a "gang box" where the wires are housed, and your wiring needs to be up to code with load, line, ground, and neutral wires.
There are some configurations (e.g. 3-way) when you may need to replace more than one switch that control the same lights. For more information about 3-way, 4-way, and multi-way switch configurations, please see our diagrams here.
For which fixtures can work with your switch, please see here.
