At the Donjon Shipbuilding and Repair production, fabrication and assembly facilities, lighting maintenance was a constant battle. Located on the Lake Erie shore in Erie, Pa., the over 200,000 sq. ft. facility boasts a 92-foot ceiling height on the main floor, plus a 125-foot high ceiling over a portion of the massive graving dock. Longer than four football fields, the Donjon graving dock is one of only two on the Great Lakes able to accommodate 1,000-foot self-unloading vessels for construction, repair, conversion, repowering and maintenance.
The Challenge: Failure at Soaring Heights
Even with a whopping 266 1,000W metal halide fixtures in place, fewer than 60 were typically in operation at any given time. In addition to the notoriously short life of the metal halide lamps, the damp, harsh, high-vibration environment inside the open air facility took a major toll on both bulbs and ballasts. Of course, the exceptional ceiling height made getting up there to change bulbs and fixtures a huge obstacle.
