The National Electrical Manufacturers Association (NEMA) represents nearly 400 electrical, medical imaging, and radiation therapy manufacturers. Demand for lighting equipment, as measured by NEMA’s Lighting Systems Shipments Index, increased by 2.2 percent year-over-year and by 0.4 percent quarter-to-quarter during 2015 Q2. The increase was driven by emergency lighting and fixtures which gained ground on a year-over-year basis while the ballast and lamp–large and miniature–components offset these gains with year-over-year declines.
