National Lighting Bureau reports third-quarter 2010 Lighting Systems Index improvements
Third-quarter 2010 NEMA Lighting Systems Index (LSI) performance bested the second quarter’s by 0.9% and was 5.6% ahead of third-quarter 2009’s.
Third-quarter 2010 NEMA Lighting Systems Index (LSI) performance bested the second quarter’s by 0.9% and was 5.6% ahead of third-quarter 2009’s, the National Lighting Bureau (NLB) reports.
Established in 1998, NEMA’s LSI is a composite measure of lamps, luminaires, ballasts, emergency lighting, exit signs, and other lighting products shipped nationally and internationally from the United States by the 450 companies that comprise the National Electrical Manufacturers Association (NEMA). Adjusted for the season and inflation, the Index uses 2002 data for its 100-point benchmark.
The new commercial/industrial-construction markets are the principal drivers of lighting-equipment sales. Both are weak and will remain so through most of 2011.
NLB Executive Director John Bachner commented that existing lighting-system upgrades will probably account for most commercial and industrial equipment sales in the near term. Indeed, while the third-quarter LSI performance improvement can be attributed to growth scattered throughout the product groups tracked by the Index, fluorescent-ballast shipments registered the most appreciable increase, a development Bachner attributed to the July 1, 2010 phase-out of magnetic ballasts used for T12 fluorescent systems.
