The Harry S. Truman Building is the State Department’s Washington, D.C. headquarters. Its main corridor spans two city blocks and contains more than 150 lighting fixtures. But that’s just a sliver of the building, which contains 34,000 fluorescent lights with ballasts in its 2.6 million-square-foot structure.
