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.
