Lutron Electronics is an American technology company founded in 1961 by Joel Spira in Coopersburg, Pennsylvania. The company is privately held and remains under family ownership. Lutron is widely credited with inventing the solid-state dimmer in 1961, a breakthrough that established the company as a pioneer in lighting control technology.
Lutron specializes in lighting control systems, motorized window shading, and related building automation technologies. In the luxury residential market, the company's flagship offering is the Lutron HomeWorks QSX system, a whole-home lighting and shading control platform that allows precise adjustment of lighting scenes, natural daylight management, and integration with home automation and audio-visual systems. The RadioRA 3 and Caseta systems serve the premium and accessible tiers, respectively.
The company's product range includes architectural dimmers, keypads, occupancy and daylight sensors, motorized roller shades, drapery tracks, and exterior shading systems. Lutron's Sivoia QS and Palladiom shading lines are particularly prominent in the luxury segment, offering whisper-quiet motorized window treatments in a wide range of fabrics and configurations. The Ketra brand, acquired by Lutron in 2018, provides tunable white and full-spectrum LED lighting for circadian and wellness-focused applications.
Lutron operates manufacturing facilities in Coopersburg, Pennsylvania, and multiple locations in the United States and internationally. Products are sold through authorized dealers, lighting designers, architects, and electrical distributors. Lutron systems are installed in luxury residences, five-star hotels, commercial buildings, and institutional facilities worldwide. The company holds over 2,700 patents globally.
