NEMA Business Information Services (NEMA/BIS) works closely with members of the NEMA Lighting Systems Division to collect domestic product shipment data. On a quarterly schedule, NEMA/BIS uses the data collected from members and seasonal adjustment factors to produce three lamp index reports which are focused on A-line, high intensity discharge (HID), and linear florescent lamp shipments.
Two graphs are provided for each product group. The index is displayed on a line graph which depicts the changes in the market over time. A bar chart shows market penetration by product type within the consumer lamp market.
A-Line Lamp Market
LED A-line lamps continue to grow, accounting for 32.4 percent of the market in third quarter 2016, and posting a 124.2 percent increase in shipments compared to 3Q 2015. They posted a 65.1 percent quarter-over-quarter (q/q) increase in the third quarter of 2016 compared to the previous quarter. Halogen, incandescent, and compact fluorescent lamps (CFLs) all posted a q/q decrease of 7.5 percent, 17.2 percent, and 12.8 percent, respectively. Incandescent lamp shipments showed a 5.6 percent increase in 3Q 2016 compared to 3Q 2015, while halogen and CFLs posted a 11 percent and 53.9 percent decrease for the same time period.
Halogen A-line lamps account for 44.5 percent of the consumer lamp market in 3Q 2016. CFLs captured 13.2 percent of the 3Q 2016 consumer lamp market and incandescents, 10 percent. Incandescent A-line lamps largely consist of 15W and 25W lamps.
Linear Florescent Lamp Market
Since 2014 the linear florescent lamp index has been on a downward trend and that trend continues in 3Q 2016. The index for T8 lamps which account for 63.0 percent of the consumer lamp market decreased on a year-over-year (y/y) basis by 27.3 percent in 3Q 2016 compared to 3Q 2015. T5 and T8 shipments also continued to decline decreasing by 27.7 and 27.3 percent respectively on a y/y basis.
In 2010, NEMA/BIS added tubular light-emitting diode (T-LED) shipments to the market penetration graph to begin tracking their impact on the market. When more historical data is available, T-LED shipments will be added to the index. In 3Q 2016, T-LEDs accounted for 12.8 percent of the florescent lamp shipments. T5 lamps claim a 9.4 percent share of the 3Q 2016 market and T12 lamps 14.8 percent.
HID Lamp Market
NEMA’s shipment index for high intensity discharge (HID) lamps continued to decline in the third quarter of 2016. Compared to the same quarter last year, metal halide lamp shipments fell 25.4 percent, sodium vapor lamps decreased by 15.2 percent, and shipments of mercury vapor lamps decreased by 11.0 percent.
Metal halide lamps accounted for 60.3 percent of the HID market in 3Q 2016, while sodium vapor and mercury vapor account for 35.6 percent and 4.2 percent respectively.
Lighting System Index
NEMA’s Lighting System Shipment Index, a measure of demand for lighting equipment, decreased by 9.7 percent in 3Q 2016 compared to 3Q 2015 and 4.7 percent decrease compared to 2Q 2016.
The decrease was driven by all components of the index that includes fixtures, emergency lighting, ballast, and lamp (large and miniature) components, all of which posted year-over-year decreases.
