To reduce energy consumption stemming from lighting, some of the fixtures in Army office buildings have been delamped and building energy managers have instituted the policy of turning lights off when not in use. Even with these measures, lighting is still one of the largest consumers of electricity. The current problem is to find ways to reduce the energy consumption of lighting systems when they are in use. The objectives of this research was to provide information on the performance and energy savings potential of constant level lighting (CLL) controls. Based on a review of product information, researchers selected the Conservolite Plus 20 for testing and installed it in 10 office spaces. After 4 months of operation, a survey of the office occupants revealed that they were satisfied with the CLL system. Although electrical cost savings were realized, the payback period varied greatly, depending on the cost of replacing old or inoperable lamps and ballasts. Before large scale installation of CLL systems, it is recommended that the power factor and harmonic distortion be monitored at a large facility.
