Verbiage:
Shipments of traditional A-line incandescent lamps, as measured by NEMA’s lamp shipment index, decreased for the third consecutive quarter in Q2 2013, reaching a low point for the series. Second quarter activity showed a decline of 8.6 percent from the previous quarter. Moreover, the index fell by 20.6 percent on a year-over-year basis.

High-intensity discharge lamps:
The index for mercury vapor lamp shipments continued to track downward, declining by 8.2 percent on a year-over-year (y/y) basis. Likewise, shipments of metal halide lamps fell 6.4 percent y/y, landing at the second lowest level in the series history. Sodium vapor was the lone HID index segment to show improvement. Following four consecutive quarters of y/y declines, the index stabilized during 2013 Q2 by registering a gain of 0.4 percent.
