Shepherdstown, WV - Lighting-equipment demand fell 4.7% between the second and third quarters of 2016, according to data developed by the National Electrical Manufacturers Association (NEMA) for its Lighting-Systems Index (LSI), a seasonality- and inflation-adjusted composite measure of luminaires, ballasts, miniature lamps, large lamps, and emergency lighting shipped throughout the United States by NEMA members. NEMA used 2002 data to create the LSI's 100-point benchmark.

According to Laurie M. Miller, NEMA's director of statistical operations, the year-over-year LSI decline was even more dramatic: Third-quarter 2016 demand was 9.7% less than third-quarter 2015 demand. Demand fell for all monitored equipment: luminaires, ballasts, miniature lamps, large lamps, and emergency lighting. 

National Lighting Bureau (NLB) Executive Director John Bachner commented, "The lighting market has changed and its rapid evolution shows no sign of let-up. Traditional lighting is being replaced by new technology, LED-based [light-emitting-diode-based] products in particular. For example, between the second and third quarters of 2016, halogen-lamp shipments fell 7.5%, compact-fluorescent-lamp (CFL) shipments fell 12.8%, and incandescent-lamp shipments fell 17.2%. By contrast, during the same period, LED A-line lamps shipments posted a 124.2% increase. The falling prices of many LED products make the lighting source's energy efficiency, versatility, adaptability, and longevity even more attractive. In short, the electric-illumination industry is changing. I suspect that the metrics used to monitor its health will be changing, too."
