In almost 50 years of innovation, Lutron has invented hundreds of lighting control devices and systems, and expanded their product offering from 2 products to 15,000. Lutron dimmers not only set the perfect mood in a home, they also reduce energy consumption and extend lamp life. Taken as a whole, Lutron light controls have reduced electrical use by 9.2 billion kWh, reducing their customers' electric bills by $1 billion annually. The company has advanced the technology of lighting control while focusing on exceptional quality and design. Since the beginning, the company has maintained exceptional service, offering 24-hour technical support for its products, and a friendly customer service department.
