Menlo Park, New Jersey, served as Edison's primary research laboratory. It was the world's first industrial research lab, equipped with workshops, laboratories, and a library, enabling Edison and his team to conduct experiments and develop inventions.

Edison moved his laboratory to West Orange, New Jersey, expanding its size and capabilities. The West Orange laboratory became a major center for research and development in various fields, including electricity, phonography, and motion pictures. The site included numerous buildings and a vast library.

While not a laboratory, Glenmont, Edison's estate in West Orange, provided him with a place to relax and contemplate his work. It also served as a meeting place for his colleagues and business associates.
