Previously, the plant was illuminated with standard, high bay industrial-type luminaires with acrylic and aluminum reflectors. The fixtures, which utilized high-pressure sodium lamps, cast a yellowish light that made the atmosphere appear dark and gloomy. The luminaires also attracted dirt and were difficult to clean and maintain. We were also interested in increasing visibility for our employees because they must be able to see to process, inspect and ship product.
Studies show that a bright, well-lighted atmosphere contributes to improved employee morale.
Changing from high pressure sodium to metal halide lamps provides the perception of higher light levels. Prior to system selection, Walters set up a demonstration in the engineering office to provide department managers the opportunity to examine the Vantage units firsthand and provide feedback. Fixture spacing is 18 feet on center. According to Walters, one of the challenges maintenance personnel faced was where to place the fixtures around existing equipment. The plant includes several mezzanines, conveyors and tall product equipment and HVAC ducts that required the layout to be changed as the project progressed.
