Leviton was founded by Isidor Leviton in 1906. After immigrating from Russia to the United States, Isidor Leviton opened a small tinsmithing business producing mantle tips used for gas lighting. Soon with the introduction of Edison's light bulb, the small family business shifted production to manufacture a single electrical product - the pull-chain lamp holder. From that one electrical device, Leviton has been churning out groundbreaking products that improve electrical safety, enhance communication, provide efficiency and cost savings and add convenience, value and comfort to our world. Leviton dimmers can help you create the perfect ambiance. Available in a wide variety of designs, their controls help conserve energy and reduce overall energy costs.In addition to controlling lighting levels in the home, dimmers also conserve energy.
