NEMA’s indexes for incandescent and compact fluorescent (CFL) lamp shipments increased by 29.4 and 3.6 percent, respectively, during Q4 2011 compared to Q3 2011. Incandescent lamp shipments posted a year-over-year gain of 41 percent while CFLs declined by 6.6 percent. The calendar year comparison also showed divergent paths. Shipments of CFLs decreased by 6.6 percent compared to 2010. Conversely, incandescent lamp shipments rose 16.4 percent during 2011. A preponderance–62.1 percent–of the increase over last year occurred during Q4.
Incandescent lamps increased its share of the combined incandescent-CFL market registering a reading of 82.8 percent. Meanwhile, the share of CFLs decreased to 17.2 percent –a ratio of slightly less than one in six lamps sold. The increase in the foothold by incandescent lamps is likely to continue while the new efficiency regulations established by EISA 2007 are phased-in over the next few years. CFLs and other substitute lamp types such as halogen A-Line and LED lamps are then expected to carve out increasing shares of the traditional A-Line market.
