ROSSLYN, Va.—The NEMA Lighting Systems Index is a composite measure of NEMA member companies’ U.S. shipments of a variety of lighting products, including lamps, luminaires, ballasts, emergency lighting, and exit signs, and is designed to track underlying demand for these types of equipment. Product shipments data are drawn from statistical surveys conducted regularly by NEMA and are adjusted for inflation and regularly recurring seasonal fluctuations.
The first quarter of 2017 saw a 1.4 percent increase compared to 4Q 2016 but a 3.4 percent decline when compared to 1Q 2016. Emergency lighting, fixtures, and lighting controls posted quarter-over-quarter increases while the remaining components declined during the same period.
The same components also posted year-over-year increases, but were offset by the decline in ballasts – HID and florescent, LED drivers, large lamps, and LED replacement lamp shipments.
