SPI Lighting is an independently-owned commercial lighting manufacturer located in Mequon, Wisconsin.
Lee A. Doerr, Jr. (president) purchased SPI Lighting in 1987 from Cooper Industries with the ambition of building on the company’s reputation as a pioneer of high-efficiency indirect lighting.
SPI grew rapidly in the following years, significantly expanding its manufacturing facilities, office personnel, and product line – most prominently with the acquisition of the architectural lighting company, Advent Lighting, in 1999.
Celebrating its 30th anniversary in 2017, SPI Lighting continues to innovate with energy-efficient LED lampings available in most fixtures, as well as custom design and manufacturing capabilities through its YD Lighting division.
While much has changed over the years, SPI Lighting remains committed to its core principles: service, performance, and innovation.
