The information on this page pertains to the Department of Energy’s (DOE) analysis of and unit sales forecast for five lamp types, which was mandated by the Energy Independence and Security Act of 2007 (EISA 2007).

Among the requirements of subtitle B of title III of EISA 2007 were provisions directing DOE to evaluate and publish within 1 year a benchmark unit sales estimate for five types of incandescent lamps (rough service lamps, vibration service lamps, 3-way incandescent lamps, 2,601–3,300 lumen general service incandescent lamps, and shatter-resistant lamps). These lamp types were not made subject to the regulatory standards for general service incandescent lamps established by EISA 2007. Among the requirements of subtitle B of title III of EISA 2007 were provisions directing DOE to collect, analyze, and monitor unit sales of these five lamp types.

More specifically, section 321(a)(3)(B) of EISA 2007 amends section 325(l) of the Energy Policy and Conservation Act (EPCA) by, in part, adding paragraphs (4)(B) and (4)(C), which direct DOE to do the following for each of the five lamp types in consultation with the National Electrical Manufacturers Association (NEMA):

  • Collect historical unit sales data from 1990 through 2006
  • Construct a spreadsheet model based on coincident economic indicators that closely match the historical annual growth rates of each lamp type to provide a neutral comparison benchmark estimate of future unit sales
  • For each year from 2010 through 2025, collect unit sales data and compare the actual lamp sales in that year with the benchmark unit sales estimate to determine if the forecast has been exceeded.

If DOE finds that the unit sales for any of the five lamp types in a given year exceed the benchmark unit sales estimate by 100 percent (i.e., more than double the anticipated sales), then regulatory action on that lamp type will be initiated.

Standards for Certain Lamps Exempted from General Service Incandescent Lamp Standards

The five types of incandescent lamps discussed here were statutorily exempted from energy conservation standards due to their low market share. In order to verify that such basis for exemption remains valid, EISA 2007 directs DOE to monitor their shipments

In consultation with NEMA, DOE gathered historical shipment data on the five lamp types for 1990 through 2006. DOE then used that data to construct spreadsheet models for each lamp type that forecast unit sales estimates to 2025. The material below contains all the information associated with this forecast, including a Notice of Data Availability to inform stakeholders of the publication of the forecasts; a report that summarizes the definitions, methodology, and findings; and a spreadsheet that presents the numerical analysis.

Starting in 2011, in consultation with NEMA, DOE gathered actual shipment data for the previous year for a comparison of actual unit sales against the benchmark unit sales estimates. The results of these comparisons are available below.

To date, none of the five lamp types unit sales have crossed the statutory threshold for a standard. DOE will continue to monitor these five lamp types and determine whether an energy conservation standards rulemaking is required, consistent with 42 U.S.C. 6295(l)(4)(D)-(H).

Test Procedure for Certain Lamps Exempted from General Service Incandescent Lamp Standards

As these lamp types are currently not subject to regulatory standards, there are no test procedures.

Waivers, Exceptions, and Exemptions

The five types of incandescent lamps discussed here were statutorily exempted from energy conservation standards. As these lamp types are currently not subject to regulatory standards, there are no waivers or exception relief for these products.

Statutory Authority

As amended, Part A, the "Energy Conservation Program for Consumer Products Other Than Automobiles" of Title III of EPCA exempts several lamp types from the definition of General Service Incandescent Lamp. (42 U.S.C. 6291(30)(D)) Further direction for establishing standards for the five lamp types discussed here is given as "Energy Efficiency Standards for Certain Lamps" under Part A. (42 U.S.C. 6295(l)(4))

Historical Information

EISA 2007 (Pub. L. 110-140) was enacted on December 19, 2007, amending EPCA to direct DOE to collect, analyze, and monitor unit sales of the five lamp types discussed here.
