RadioRAR 2 Lamp Dimmers function much like standard lamp dimmers, but can be controlled as part of a lighting control system. Lamp Dimmers are useful in locations where plug-in lamps need to be dimmed or non-dimmable lighting loads need to be switched. RadioRAR 2 Lamp Dimmers incorporate advanced features such as fade on/fade off, delayed long fade off, and rapid full on. RadioRAR 2 Lamp Dimmers are simple to install and easy to use.
