This September 2020 study by a team from the University of Oregon summarizes the results of a field study which compared Luminaire Level Lighting Controls (LLLC) to Networked Lighting Controls (NLC). Specifically, the research set out to determine if LLLC systems, applied as one-for-one (1:1) replacement retrofit solutions, can provide lighting energy savings and lighting quality comparable to more comprehensive networked lighting control (NLC) redesign solutions. The latter also require significant cost investment in design, specification, and install. Cost data indicates LLLC savings of one-third to one-half the cost of more comprehensive NLC solutions. Methodology and detailed analysis are provided.
