NEMA’s Lighting Systems Index (LSI) ticked 0.9% higher on a quarter-to-quarter basis during 2010Q3. On a year-over-year basis, the index showed a 5.6% gain compared to the third quarter of 2009. Although the LSI has trended higher since hitting a cyclical (and all-time) low during the second quarter of 2009, aggregate lighting equipment demand remains at a very low level. In terms of the underlying mix of lighting systems products, growth was scattered across all five groups, but only fluorescent ballast shipments registered anything resembling an appreciable increase in demand from a year ago.
