Modern Lighting System Design for the Holland Tunnel

In 1927, a modem vehicular tunnel lighting system consisted of incandescent lamps mounted within the tunnel walls to provide illumination on the roadway. New York´s Holland Tunnel, which was opened to traffic during that year, was designed with such a lighting system. In 1960, it was decided to modernize this system. To accomplish this, a new fluorescent lighting fixture and system that had to provide a high level of illumination in the tunnel while utilizing and adapting the existing tunnel electrical system at minimum cost, was designed, developed, and installed.
