LSI Industries Inc

James A. Clark leads LSI Industries, a publicly traded manufacturer founded in 1976 by Robert Ready. The company began as a petroleum-station lighting supplier and went public on NASDAQ in 1985 (ticker LYTS). LSI produces lighting for outdoor, indoor, emergency, and sports applications, alongside graphics and digital signage. The firm serves automotive, grocery, pharmacy, parking, refueling, QSR, retail, warehouse, and data-center markets. Named client CarMax is highlighted in a case study. LSI also makes its own LED circuit boards and offers wireless lighting controls, with a portfolio including brands such as ADL Technology, Atlas Lighting, EMI Industries, and JSI Store Fixtures. LSI operates from Cincinnati, with additional sites listed as ADL Technology, Atlas Lighting, EMI Industries, JSI Store Fixtures, Royston Group, CBSF, and others. The company employs an unspecified number of professionals. In May 2026, LSI published a case study featuring CarMax as a client. LSI is distinctive as a publicly traded industrial manufacturer rather than a family office or investment firm. It operates under the leadership of James A. Clark, who has driven a transformation toward LED and wireless controls. The firm's heritage traces to a single founder's insight about poorly lit gas stations, and it now competes in the broader commercial and sports-lighting market, with a focus on American-made products.
