The National Electrical Manufacturers Association (NEMA) and the National Lighting Bureau (NLB) have reported that the second quarter 2012 NEMA Lighting Systems Index (LSI) has gained 2.9 percent from first-quarter performance and 6.6 percent over second-quarter 2011. The LSI was established in 1998 and is a composite measure of luminaires, ballasts, miniature lamps, large lamps, and emergency lighting shipped nationally and internationally from the United States by the 450 companies that are NEMA members. In a prepared statement, NLB Executive Director John Bachner commented that the gains are notable “because all five categories of lighting systems products tracked by the Index registered solid gains compared to the second quarter of 2011.”
