This dimmer also includes all the interchangeable faces you need in one convenient package, bundled together in the three most popular colors - white, light almond and ivory - if you change your mind on the color, swapping out the face place is literally a snap! The convenient slide ON/OFF is easy to operate and there is no de-rating required in multi-gang applications. The device is also contained in a tough, impact-resistant thermoplastic housing and offers both single pole and three-way functionality in one device and no de-rating is required in multi-gang applications. Dimmers are a simple, easy way to help save energy and extend bulb life by reducing the amount of electricity needed to power the lights. They also allow you to match the light level you need for the task at hand or simply create ambiance in a room.
