SPI Lighting is a leading designer and manufacturer of American made architectural and performance luminaires.

In the 1970’s, Alan Ruud founded SPI Lighting. Ruud later sold it to McGraw-Edison, which became part of Cooper Industries.

In 1987, Lee A. Doerr, Jr. purchased SPI Lighting from Cooper Industries with the vision of building upon the company’s reputation as a pioneer of high-efficiency indirect lighting.

The company 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.

In the decades that followed, SPI Lighting continued to innovate with energy-efficient LEDs and became well known for its product innovation, factory flexibility, and custom capabilities.

In 2019, Mr. Doerr passed away. The following year, SPI Lighting joined Bukas Lighting Group, a North American LED lighting innovator concentrating on specification, architectural, and industrial grade lighting solutions. SPI Lighting continues to operate independently from the same vertically integrated manufacturing facility in Mequon, Wisconsin.

While much has changed over the past several decades, we remain committed to our core principles: service, performance, and innovation.
