[Docket Number EE-2007-BT-STD-0016]
RIN 1904-AB50
SummaryThe Energy Policy and Conservation Act of 1975 (EPCA), as amended, prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including fluorescent lamp ballasts. EPCA also requires the U.S. Department of Energy (DOE) to determine whether any new or amended standards would be technologically feasible and economically justified, and would save a significant amount of energy. In this final rule, DOE adopts new and amended federal energy conservation standards for fluorescent lamp ballasts. It has determined that the new and amended energy conservation standards for these products would result in significant conservation of energy, and are technologically feasible and economically justified.
DatesThe effective date of this rule is January 13, 2012. Compliance with the new and amended standards established for fluorescent lamp ballasts in today's final rule is required as of November 14, 2014.

IX. Approval of the Office of the SecretaryI. Summary of the Final RuleTitle III, Part B (1)
of the Energy Policy and Conservation Act of 1975 (EPCA or the Act), Public Law 94-163 (42 U.S.C. 6291-6309, as codified), established the Energy Conservation Program for Consumer Products Other Than Automobiles. Pursuant to EPCA, any new or amended energy conservation standard that DOE prescribes for certain products, such as fluorescent lamp ballasts (ballasts), shall be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) Furthermore, the new or amended standard must result in a significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) In accordance with these and other statutory provisions discussed in this notice, DOE adopts new and amended energy conservation standards for ballasts. The new and amended standards, which are based on ballast luminous efficiency (BLE), the ratio of total lamp arc power to ballast input power as defined in Appendix Q1 of title 10 of the Code of Federal Regulations (CFR), part 430, are shown in Table I.1. These new and amended standards apply to all products listed in Table I.1 and manufactured in, or imported into, the United States on or after the compliance date specified in theDATESsection.

Benefits and Costs to ConsumersTable I.2 presents DOE's evaluation of the economic impacts of today's standards on consumers of ballasts for the product classes analyzed as representative (see section V.B.6), as measured by the average life-cycle cost (LCC) savings and the median payback period (PBP). The average LCC savings are positive for all product classes. For example, the estimated average LCC savings are $37−$40 for 2-lamp instant start (IS) and rapid start (RS) ballasts that operate 4-foot T8 (2)
lamps in the commercial sector. When there was more than one baseline for a representative ballast type, DOE performed separate LCC analyses comparing replacement lamp-and-ballast systems to each baseline. Because T8 systems are generally more efficient and have lower overall LCCs than T12 systems, the LCC savings relative to the T8 baseline are lower than when comparing the same efficiency levels to a T12 baseline. At the adopted standard levels, however, LCC savings are positive for all replacement events and baselines analyzed.

B. Impact on ManufacturersThe industry net present value (INPV) is the sum of the discounted cash flows to the industry from the base year through the end of the analysis period (2014 to 2043). Using a real discount rate of 7.4 (3)
percent, DOE estimates that the INPV for manufacturers of ballasts in the base case ranges from $733 million to $1.22 billion in 2010 dollars (2010$). Under today's standards, DOE expects that ballast manufacturers may lose up to 36.7 percent of their INPV, which is approximately $268.6 million. Based on DOE's interviews with the manufacturers of ballasts, however, DOE does not expect any plant closings or significant employment loss. See section VII.B.2.b and VIII.B.3.b for additional discussion on this topic.C. National BenefitsDOE's analyses indicate that today's ballast standards would save a significant amount of energy over 30 years (2014-2043)—an estimated 2.7-5.6 quadrillion British thermal units (quads) of cumulative energy. This amount is equivalent to the annual energy use of 14 million to 28 million U.S. homes. (4)
The cumulative national net present value (NPV) of total consumer costs and savings of today's ballast standards in 2010$ ranges from $6.7 billion (at a 7-percent discount rate) to $21.6 billion (at a 3-percent discount rate). This NPV expresses the estimated total value of future operating-cost savings less the estimated increased product costs for products purchased in 2014-2043, discounted to 2011.
In addition, today's ballast standards would have significant environmental benefits. The energy savings would result in cumulative greenhouse gas emission reductions of 27-106 million metric tons (Mt) of carbon dioxide (CO 2) from 2014 through 2043. During this period, the standards would also result in emissions reductions (5)
of 22-39 thousand tons of nitrogen oxides (NO X) and 0.40-1.47 tons of mercury (Hg). (6)
The value of the CO 2 reductions is calculated using a range of values per metric ton of CO 2 (otherwise known as the Social Cost of Carbon, or SCC) developed by a recent interagency process. The derivation of the SCC values is discussed in section V.L. DOE estimates that the net present monetary value of the CO 2 emissions reductions is between $0.26 and $3.94 billion, expressed in 2010$ and discounted to 2011. DOE also estimates that the net present monetary value of the NO X emissions reductions, expressed in 2010$ and discounted to 2011, is $3.91 to $40.2 million at a 7-percent discount rate, and $7.67 to $78.8 million at a 3-percent discount rate. (7)
Table I.3 summarizes the national economic costs and benefits expected to result from today's standards for fluorescent lamp ballasts.

Net Benefits Including CO 2 and NOX†9.627
The benefits and costs of today's standards, for products sold in 2014-2043, can also be expressed in terms of annualized values. The annualized monetary values are the sum of (1) the annualized national economic value, expressed in 2010$, of the benefits from operating the product (consisting primarily of operating cost savings from using less energy, minus increases in equipment purchase and installation costs, which is another way of representing consumer NPV, plus (2) the annualized monetary value of the benefits of emission reductions, including CO 2 emission reductions. (8)
Although adding the value of consumer savings to the values of emission reductions provides a valuable perspective, two issues should be considered. First, the national operating cost savings are domestic U.S. consumer monetary savings that occur as a result of market transactions, while the value of CO 2 emissions reductions is based on a global value. Second, the assessments of operating cost savings and CO 2 savings are performed with different methods that use different time frames for analysis. The national operating cost savings are measured for the lifetime of ballasts shipped in 2014-2043. The SCC values, alternatively, reflect the present value of all future climate-related impacts resulting from the emission of one metric ton of CO 2 in each year, with impacts continuing well beyond 2100.
Estimates of annualized benefits and costs of today's standards are shown in Table I.4. (The following monetary values are expressed in 2010$.) The results under the primary estimate are as follows. Using a 7-percent discount rate for benefits and costs other than CO 2 reduction, for which DOE used a 3-percent discount rate along with the SCC series corresponding to a value of $22.3/ton in 2010, the cost of the standards in today's rule is $363 million per year in increased equipment costs, while the benefits are $1.2 billion per year in reduced equipment operating costs, $92 million in CO 2 reductions, and $2.2 million in reduced NO X emissions. In this case, the net benefit amounts to $920 million per year. Using a 3-percent discount rate for all benefits and costs and the SCC series corresponding to a value of $22.3/ton in 2010, the cost of the standards in today's rule is $385 million per year in increased equipment costs, while the benefits are $1.3 billion per year in reduced operating costs, $92 million in CO 2 reductions, and $2.4 million in reduced NO X emissions. In this case, the net benefit amounts to $1.1 billion per year.

D. ConclusionBased on the analyses culminating in this final rule, DOE found the benefits to the nation of the standards (energy savings, consumer LCC savings, positive NPV of consumer benefit, and emission reductions) outweigh the costs (loss of INPV). DOE has concluded that the standards in today's final rule represent the maximum improvement in energy efficiency that is technologically feasible and economically justified, and would result in significant conservation of energy. DOE further notes that in all product classes, ballasts achieving the standard levels are already commercially available.II. IntroductionThe following section briefly discusses the statutory authority underlying today's final rule, as well as some of the historical background related to the establishment of standards for ballasts.A. AuthorityTitle III, Part B of the Energy Policy and Conservation Act of 1975, Public Law 94-163 (42 U.S.C. 6291-6309, as codified) established the Energy Conservation Program for Consumer Products Other Than Automobiles, (9)
a program covering most major household appliances (collectively referred to as “covered products”), which includes the types of ballasts that are the subject of this final rule. (42 U.S.C. 6292(a)(13)) EPCA prescribed energy conservation standards for these products (42 U.S.C. 6295(g)(5), (6), and (8)), and directed DOE to conduct two cycles of rulemakings to determine whether to amend these standards. (42 U.S.C. 6295(g)(7))
Pursuant to EPCA, DOE's energy conservation program for covered products consists essentially of four parts: (1) Testing; (2) labeling; (3) the establishment of Federal energy conservation standards; and (4) certification and enforcement procedures. The Federal Trade Commission (FTC) is primarily responsible for labeling, and DOEimplements the remainder of the program. Subject to certain criteria and conditions, DOE is required to develop test procedures to measure the energy efficiency, energy use, or estimated annual operating cost of each covered product. (42 U.S.C. 6293) Manufacturers of covered products must use the prescribed DOE test procedure as the basis for certifying to DOE that their products comply with the applicable energy conservation standards adopted under EPCA and when making representations to the public regarding the energy use or efficiency of those products. (42 U.S.C. 6293(c) and 6295(s)) Similarly, DOE must use these test procedures to determine whether the products comply with standards adopted pursuant to EPCA. Id. The DOE test procedures for ballasts currently appear at 10 CFR part 430, subpart B, appendices Q and Q1. Compliance with the ballast efficacy factor energy conservation standards, required until the compliance date specified in theDATESsection, is determined according to appendix Q. Compliance with the BLE standards adopted in this rule must be determined according to appendix Q1. The procedures in appendix Q1 were established by the ballast active mode test procedure final rule. 76 FR 25211 (May 4, 2011).
DOE must follow specific statutory criteria for prescribing new or amended standards for covered products. As indicated in the beginning of section I, any new or amended standard for a covered product must be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) Furthermore, DOE may not adopt any standard that would not result in the significant conservation of energy. (42 U.S.C. 6295(o)(3)) Moreover, DOE may not prescribe a standard: (1) For certain products, including ballasts, if no test procedure has been established for the product, or (2) if DOE determines by rule that the new or amended standard is not technologically feasible or economically justified. (42 U.S.C. 6295(o)(3)(A)-(B)) In deciding whether a new or amended standard is economically justified, DOE must determine whether the benefits of the standard exceed its burdens. (42 U.S.C. 6295(o)(2)(B)(i)) DOE must make this determination after receiving comments on the proposed standard, and by considering, to the greatest extent practicable, the following seven factors:
7. Other factors the Secretary of Energy (the Secretary) considers relevant.
EPCA, as codified, also contains what is known as an “anti-backsliding” provision, which prevents the Secretary from prescribing any new or amended standard that either increases the maximum allowable energy use or decreases the minimum required energy efficiency of a covered product. (42 U.S.C. 6295(o)(1)) Also, the Secretary may not prescribe a new or amended standard if interested parties have established by a preponderance of the evidence that the standard is likely to result in the unavailability in the United States in any covered product type (or class) of performance characteristics (including reliability), features, sizes, capacities, and volumes that are substantially the same as those generally available in the United States. (42 U.S.C. 6295(o)(4))
Additionally, 42 U.S.C. 6295(q)(1) specifies requirements when promulgating a standard for a type or class of covered product that has two or more subcategories. DOE must specify a different standard level than that which applies generally to such type or class of products for any group of covered products which have the same function or intended use if products within such group—(A) consume a different kind of energy from that consumed by other covered products within such type (or class); or (B) have a capacity or other performance-related feature which other products within such type (or class) do not have and such feature justifies a higher or lower standard. Id. In determining whether a performance-related feature justifies a different standard for a group of products, DOE must consider such factors as the utility to the consumer of such a feature and other factors DOE deems appropriate. Id. Any rule prescribing such a standard must include an explanation of the basis on which such higher or lower level was established. (42 U.S.C. 6295(q)(2))
Pursuant to the amendments contained in section 310(3) of the Energy Independence and Security Act of 2007 (EISA 2007), any final rule for new or amended energy conservation standards promulgated after July 1, 2010, is required to address standby mode and off mode energy use. (42 U.S.C. 6295(gg)(3)) Specifically, when DOE adopts a standard for a covered product after that date, it must, if justified by the criteria for adoption of standards under EPCA (42 U.S.C. 6295(o)), incorporate standby mode and off mode energy use into the standard or, if that is not feasible, adopt a separate standard for such energy use for that product. (42 U.S.C. 6295(gg)(3)(A)-(B)) DOE has determined that ballasts do not operate in an “off mode” as defined by EPCA (42 U.S.C. 6291(gg)(1)(A)(ii)), and that the only ballasts that consume power in a “standby mode” as defined by EPCA (42 U.S.C. 6291(gg)(1)(A)(iii)) are those that incorporate an electronic circuit enabling the ballast to communicate with and be part of a lighting control system. DOE's test procedures for ballasts address such standby mode energy use. 74 FR 54455 (October 22, 2009) and 76 FR 25211 (May 4, 2011); 10 CFR part 430, subpart B, appendix Q, section 3.2 and appendix Q1, section 3. DOE did not adopt standards for standby mode energy use, however, because DOE did not find any covered ballasts capable of operating in thismode in its search of the marketplace. Therefore, this final rule does not include energy conservation standards for standby mode energy use. See section III.B for more detail.
DOE emphasizes as well that Executive Order 13563 requires agencies “to use the best available techniques to quantify anticipated present and future benefits and costs as accurately as possible.” In its guidance, the Office of Information and Regulatory Affairs has emphasized that such techniques may include “identifying changing future compliance costs that might result from technological innovation or anticipated behavioral changes.” For the reasons stated in the preamble, DOE concludes that today's final rule is consistent with these principles, including the requirement that, to the extent permitted by law, benefits justify costs and that net benefits are maximized. Consistent with EO 13563, and the range of impacts analyzed in this final rule, the energy efficiency standards adopted herein by DOE achieve maximum net benefits.B. Background1. Ballast Efficacy Factor StandardsThe Federal energy conservation standards for ballasts expressed in terms of ballast efficacy factor are set forth in Table II.1 and Table II.2. The standards in Table II.1 were adopted in a final rule published on September 19, 2000, which completed the first of the two rulemakings required under 42 U.S.C. 6295(g)(7) to consider amending the standards for ballasts (hereafter referred to as the 2000 Ballast Rule). 65 FR 56739. The standards in Table II.2 were established by amendments to EPCA in the Energy Policy Act of 2005 (EPAct 2005), Pub. L. 109-58.

In summary, as reflected in the previous two tables, the ballasts currently regulated under EPCA consist of ballasts that are designed to operate: One and two nominally 40-watt (W) and 34W 4-foot T12 medium bipin (MBP) lamps (F40T12 (10)
and F34T12); Two nominally 75W and 60W 8-foot T12 single-pin (SP) slimline lamps (F96T12 and F96T12/ES); and
Two nominally 110W and 95W 8-foot T12 recessed double contact high output lamps (F96T12HO and F96T12HO/ES) at nominal input voltages of 120 or 277 volts (V) with an input current frequency of 60 hertz (Hz).In addition, several ballasts are exempt from standards. These exemptions consist of ballasts designed to operate those lamps listed in Table II.1 that: Are designed for dimming to 50 percent or less of its maximum output;
Are designed for use with two F96T12 high output (HO) lamps at ambient temperatures of −20 degrees Fahrenheit (F) or less and for use in an outdoor sign; or
Have a power factor of less than 0.90 and are designed and labeled for use only in residential building applications.2. History of Standards Rulemaking for Fluorescent Lamp BallastsEPCA establishes energy conservation standards for certain ballasts and requires that DOE conduct two cycles of rulemaking to determine whether to amend the standards for these ballasts, including whether to adopt standards for additional ballasts. (42 U.S.C. 6295(g)(5)-(8)) As indicated in section II.B.1, DOE completed the first of these rulemaking cycles by publishing the 2000 Ballast Rule. 65 FR 56740 (Sept. 19, 2000). In this rulemaking, the second rulemaking cycle required by 42 U.S.C. 6295(g)(7), DOE is amending the existing standards for ballasts and adopting standards for additional ballasts.
DOE initiated this rulemaking on January 14, 2008 by publishing in theFederal Registera notice announcing the availability of the “Energy Conservation Standards Rulemaking Framework Document for Fluorescent Lamp Ballasts.” (A PDF of the framework document is available at http://www1.eere.energy.gov/buildings/appliance_standards/residential/pdfs/ballast_framework_011408.pdf.) In that notice, DOE also announced a public meeting on the framework document and requested public comment on the matters raised in the document. 73 FR 3653 (Jan. 22, 2008). The framework document described the procedural and analytical approaches that DOE anticipated using to evaluate energy conservation standards for the ballasts, and identified various issues to be resolved in conducting this rulemaking.
DOE held the public meeting on February 6, 2008, where it: Presented the contents of the framework document; described the analyses it planned to conduct during the rulemaking; sought comments from interested parties on these subjects; and in general, sought to inform interested parties about, and facilitate their involvement in, the rulemaking. Interested parties at the public meeting discussed the active mode test procedure and several major analyses related to this rulemaking. At the meeting and during the period for commenting on the framework document, DOE received feedback that helped identify and resolve issues involved in this rulemaking.
DOE then gathered additional information and performed preliminary analyses to help develop potential energy conservation standards for ballasts. DOE published in theFederal Registeran announcement of the availability of the preliminary technical support document (TSD) and of another public meeting to discuss and receive comments on the following matters: Product classes; the analytical framework, models, and tools that DOE was using to evaluate standards; the results of the preliminary analyses performed by DOE; and potential standard levels that DOE could consider. 75 FR 14319 (March 24, 2010) (hereafter referred to as the March 2010 notice). DOE also invited written comments on these subjects. Id. The preliminary TSD is available at http://www1.eere.energy.gov/buildings/appliance_standards/residential/fluorescent_lamp_ballasts_ecs_prelim_tsd.html. In the notice, DOE also requested comment on other relevant issues that would affect energy conservation standards for fluorescent lamp ballasts or that DOE should address in the notice of proposed rulemaking (NOPR). Id. at 14322.
The public meeting announced in the March 2010 notice took place on April 26, 2010. At that meeting, DOE presented the methodologies and results of the analyses set forth in the preliminary TSD. Interested parties discussed the following major issues at the public meeting: The efficiency metric; how test procedure variation might affect efficiency measurements; requirements for ballasts in environments that are sensitive to electromagnetic interference (EMI); product classes; manufacturer selling prices (MSPs) and overall pricing methodology; markups; the maximum technologically feasible ballast efficiency; cumulative regulatory burden; and shipments. DOE considered the comments received since publication of the March 2010 notice, including those received at the April 2010 public meeting, in the development of the NOPR.
In April 2011, DOE proposed new and amended energy conservation standards for fluorescent lamp ballasts. In conjunction with the NOPR, DOE also published on its Web site the complete TSD for the proposed rule, which incorporated the analyses DOE conducted and technical documentation for each analysis. The TSD included the engineering analysis spreadsheets, the LCC spreadsheet, the national impact analysis spreadsheet, and the manufacturer impact analysis (MIA) spreadsheet—all of which are available on DOE's Web site. (11)
The proposed standards were as shown in Table II.3. 76 FR 20090, 20091 (April 11, 2011).

In the NOPR, DOE invited comment in particular on the following issues: (1) The exemption for T8 magnetic (12)
ballasts in EMI-sensitive environments; (2) the appropriateness of establishing efficiency standards using an equation dependent on lamp-arc power; (3) the inclusion of several different ballast types in the same product class; (4) the methodology used to calculate manufacturer selling prices; (5) the efficiency levels considered; (6) the maximum technologically feasible level; (7) markups; (8) the inclusion T12 ballasts in the baseline analysis for life cycle costs; (9) the magnitude and timing of forecasted shipments; (10) the methodology and inputs DOE used for the manufacturer impact analysis—specifically, DOE's assumptions regarding markups, capital costs, and conversion costs; (12) the potential impacts of amended standards on small fluorescent lamp ballast manufacturers; (13) the trial standard levels (TSLs) considered; (14) the proposed standard level; and (15) potential approaches to maximize energy savings while mitigating impacts to certain fluorescent ballast consumer subgroups. 76 FR 20090, 20177 (April 11, 2011).
DOE held a public meeting on May 10, 2011, to hear oral comments on and solicit information relevant to the proposed rule (hereafter the May 2011 public meeting). At this meeting, the National Electrical Manufacturers Association (NEMA) presented test data that they found inconsistent with the data collected by DOE and that could affect the standards established in the final rule. In general, NEMA's ballast luminous efficiency values appeared to be lower than those obtained by DOE. NEMA and other stakeholders agreed that there were discrepancies between the two data sets and emphasized the importance of identifying the source of the differences. In addition, DOE received comments on the methodology used to account for compliance certification requirements, design variation, and lab-to-lab variation and on the appropriate shape of DOE's proposed efficiency level curves.
In light of these discrepancies, DOE published a notice of data availability (NODA) on August 24, 2011 to: (1) Announce the availability of additional test data collected by DOE and the data submitted by NEMA; (2) address the differences between test data obtained by DOE and test data submitted by NEMA; (3) describe the methodological changes DOE was considering for the final rule based on the additional data; (4) present efficiency levels developed using the revised methodology and all available test data; and (5) request public comment on these analyses. (13)
DOE considered the comments received in response to both the April 2011 NOPR and the August 2011 NODA when developing this final rule, and responds to these comments in the following sections.III. Issues Affecting the Scope of This RulemakingA. Additional Fluorescent Lamp Ballasts for Which DOE is Adopting Standards1. Scope of EPCA Requirement That DOE Consider Standards for Additional BallastsAs discussed in section II.A, amendments to EPCA established energy conservation standards for certain fluorescent lamp ballasts and directed DOE to conduct two rulemakings to consider amending the standards. The first amendment was completed with the publication of the 2000 Ballast Rule. This rulemaking fulfills the statutory requirement to determine whether to amend standards a second time. EPCA specifically directs DOE, in this second amendment, to determine whether to amend the standards in effect for fluorescent lamp ballasts and whether such standards should be amended so that they would be applicable to additional fluorescent lamp ballasts. (42 U.S.C. 6295(g)(7)(B))
The April 2011 NOPR notes that a wide variety of fluorescent lamp ballasts are not currently covered by energy conservation standards, and thus are potential candidates for coverage under 42 U.S.C. 6295(g)(7). DOE encountered similar circumstances in a recent rulemaking that amended standards for general service fluorescent and incandescent reflector lamps (hereafter referred to as the 2009 Lamps Rule). (14)
74 FR 34080, 34087-8 (July 14, 2009). In that rule, DOE was directed by EPCA to consider expanding its scope of coverage to include additional general service fluorescent lamps (GSFL). EPCA defines GSFLs as fluorescent lamps that can satisfy the majority of fluorescent lamp applications and that are not designed and marketed for certain specified, non-general lighting applications. (42 U.S.C. 6291(30)(B)) As such, the term “general service fluorescent lamp” is defined by reference to the term “fluorescent lamp,” which EPCA defines as “a low pressure mercury electric-discharge source in which a fluorescing coating transforms some of the ultraviolet energy generated by the mercury discharge into light,” and as including the four enumerated types of fluorescent lamps for which EPCA already prescribes standards. (42 U.S.C. 6291(30)(A); 42 U.S.C. 6295(i)(1)(B)) To construe “general service fluorescent lamp” in 42 U.S.C. 6295(i)(5) as limited to those types of fluorescent lamps would mean there are no GSFLs that are not already subject to standards, and hence, there would be no “additional” GSFLs for which DOE could consider standards. Such an interpretation would conflict with the directive in 42 U.S.C. 6295(i)(5) that DOE consider standards for “additional” GSFLs, thereby nullifying that provision.
Therefore, DOE concluded that the term “additional general service fluorescent lamps” in 42 U.S.C. 6295(i)(5) allows DOE to set standards for GSFLs other than the four enumerated lamp types specified in the EPCA definition of “fluorescent lamp.” As a result, the 2009 Lamps Rule defined “fluorescent lamp” to include:
(1) Any straight-shaped lamp (commonly referred to as 4-foot medium bipin lamps) with medium bipin bases, a nominal overall length of 48 inches, and rated wattage of 25 or more;
(2) Any U-shaped lamp (commonly referred to as 2-foot U-shaped lamps) with medium bipin bases, a nominal overall length between 22 and 25 inches, and rated wattage of 25 or more;
(3) Any rapid start lamp (commonly referred to as 8-foot high output lamps) with recessed double contact bases and a nominal overall length of 96 inches;
(4) Any instant start lamp (commonly referred to as 8-foot slimline lamps) with single pin bases, a nominal overall length of 96 inches, and rated wattage of 52 or more;
(5) Any straight-shaped lamp (commonly referred to as 4-foot miniature bipin standard output lamps) with miniature bipin bases, a nominal overall length between 45 and 48 inches, and rated wattage of 26 or more; and
(6) Any straight-shaped lamp (commonly referred to 4-foot miniature bipin high output lamps) with miniature bipin bases, a nominal overall length between 45 and 48 inches, and rated wattage of 49 or more.
In this rulemaking, DOE is directed to consider whether any amended standard should be applicable to additional fluorescent lamp ballasts. (42 U.S.C. 6295(g)(7)(B)) EPCA defines a “fluorescent lamp ballast” as “a device which is used to start and operate fluorescent lamps by providing a starting voltage and current and limiting the current during normal operation.” (42 U.S.C. 6291(29)(A)) For this rule, DOE referenced the definition of fluorescent lamp adopted by the 2009 Lamps Rule. This definition allows DOE to consider expanding coverage to include additional fluorescent lamp ballasts while not eliminating coverage of any ballasts for which standards already exist.2. Identification of the Additional Ballasts for Which DOE Establishes StandardsIn considering whether to amend the standards in effect for fluorescent lamp ballasts so that they apply to “additional” fluorescent lamp ballasts as specified in section 325(g)(7)(B) of EPCA, DOE considered all fluorescent lamp ballasts (for which standards are not already prescribed) that operate fluorescent lamps, as defined in 10 CFR 430.2. For each additional fluorescent lamp ballast, DOE considered potential energy savings, technological feasibility and economic justification when determining whether to include them in the scope of coverage. In its analyses, DOE assessed the potential energy savings from market share estimates, potential ballast designs that improve efficiency, and other relevant factors. For market share estimates, DOE used both quantitative shipment data and information obtained during manufacturer interviews. DOE also assessed the potential to achieve energy savings in certain ballasts by considering whether those ballasts could serve as potential substitutes for other regulated ballasts.
In the April 2011 NOPR, DOE proposed extending coverage to several additional ballast types including those that operate: Additional numbers and diameters of 4-foot MBP lamps, 8-foot HO lamps, and 8-foot slimline lamps; 4-foot miniature bipin (MiniBP) standard output (SO) lamps; 4-foot MiniBP HO lamps; and 8-foot HO cold temperature lamps commonly used in outdoor signs. DOE did not propose to extend coverage to additional dimming ballasts or T8 magnetic ballasts that operate in EMI-sensitive environments, provided that these magnetic ballasts were designed and labeled for use in EMI-sensitive environments only and shipped by the manufacturer in packages of 10 or fewer ballasts.
The Northwest Energy Efficiency Alliance (NEEA) and the Northwest Power and Conservation Council (NPCC), the Northeast Energy Efficiency Partnerships (NEEP), the Appliance Standards Awareness Project (ASAP), and in a joint comment, ASAP, the Alliance to Save Energy, the American Council for an Energy-Efficient Economy, the National Consumer Law Center, and the National Resources Defense Council (hereafter the “Joint Comment”) supported the proposed scope of coverage. ASAP and the Joint Comment stated that the expanded scope contributes significantly to the forecasted energy savings for this rulemaking. (NEEA and NPCC, No. 44 at p. 2 (15)
; NEEP, No. 49 at p. 2; ASAP, Public Meeting Transcript, No. 43 at pp. 80-2; Joint Comment, No. 46 at p. 2) DOE also received several comments regarding the proposed exemption for T8 magnetic ballasts that operate in EMI-sensitive environments, coverage of residential ballasts, and additional comments recommending further exemptions. These comments are discussed in further detail in the following sections.a. Ballasts That Operate in Environments Sensitive to Electromagnetic InterferenceDOE received comments at the April 2010 public meeting that standards could eliminate magnetic ballasts that are currently used in certain EMI-sensitive environments. DOE conducted research and interviews with fluorescent lamp ballast and fixture manufacturers to identify the following applications as potentially sensitive to EMI: Medical operating room telemetry or life support systems; airport control systems; electronic test equipment; radio communication devices; radio recording studios; correctional facilities; clean rooms; facilities with low signal-to-noise ratios; and aircraft hangars or other buildings with predominantly metal construction. (16)
DOE learned from manufacturer interviews that magnetic ballasts are typically recommended for situations in which EMI has been or is expected to be a concern.
Although there are several methods to reduce electromagnetic interference, available data do not indicate that EMI-related issues with electronic ballasts can be eliminated such that there are no longer safety concerns. For this reason, in the April 2011 NOPR DOE proposed an exemption for T8 magnetic ballasts designed and labeled for use in EMI-sensitive environments only and shipped by the manufacturer in packages containing 10 or fewer ballasts. DOE believed the exemption was necessary because in some environments, EMI could pose a serious safety concern that is best mitigated with magnetic ballast technology. DOE did not believe magnetic ballasts would likely be used as substitutes in current electronic ballast applications due to their higher cost and weight. 76 FR 20090, 20100-1 (April 11, 2011).
NEEA and NPCC, NEMA, and ASAP supported the exemption for magnetic ballasts in EMI-sensitive locations. (NEEA and NPCC, No. 44 at p. 2; NEMA, Public Meeting Transcript, No. 43 at p. 70; NEMA, No. 47 at pp. 2-3; ASAP, Public Meeting Transcript, No. 43 at pp. 80-2) ASAP and NEEA and NPCC suggested requiring the description “designed, labeled, and marketed for use in EMI-sensitive applications” to limit the possibility of exempted ballasts being sold in other applications. Philips commented that they are unsure how manufacturers would be able to control the marketing through distributors to the proper market. ASAP and NEEA and NPCC acknowledged that although manufacturers cannot control distribution, they can control how they market their products. (ASAP, Public Meeting Transcript, No. 43 at pp. 80-82; Philips, Public Meeting Transcript, No. 43 at p. 82; NEEA and NPCC, No. 44 at p. 2)
DOE did not receive any adverse comment regarding the exemption for T8 magnetic ballasts in EMI-sensitive applications and therefore, for the reasons discussed above, maintains this exemption in the final rule. DOE agrees with ASAP and NEEA and NPCC that this exemption should be designed such that, to the greatest extent possible, it does not become a pathway to circumvent compliance with standards adopted by this rulemaking. Therefore, DOE has modified the description of the exemption to cover ballasts “designed, labeled, and marketed for use in EMI-sensitive applications.” See appendix 5E of the TSD for more details on EMI-sensitive applications.b. Ballasts That Operate in the Residential SectorRadionic disagreed with DOE's decision to cover residential ballasts and stated that new residential modelsdeveloped to meet standards are likely to have a high initial cost. Because residential consumers are sensitive to first cost, Radionic stated that consumers will choose less expensive and less efficient technologies, thereby potentially decreasing energy savings. (Radionic, No. 36 at p. 1)
As discussed in the April 2011 NOPR, DOE believes that residential ballasts represent a sizeable portion of the overall ballast market and represent significant potential energy savings. DOE agrees with comments received in response to the preliminary TSD, stating that demand for residential fluorescent ballasts will likely grow substantially as residential building codes become more stringent. For example, California, Oregon, and Washington have codes that require fluorescent or higher-efficacy systems in homes. Similarly, the 2009 International Energy Conservation Code requires that 50 percent of all permanently installed lighting in residences have a minimum efficacy of 45 lumens per watt. 76 FR 20090, 20099 (April 11, 2011). DOE projects that increased lighting efficacy requirements will drive consumers to continue to purchase fluorescent systems despite incremental increases in first cost. Furthermore, DOE notes that consumers are already purchasing higher efficiency fluorescent ballasts despite their higher initial first cost relative to other lighting technologies. As discussed in section V.A.1 and section V.B.5.g, standards for residential ballasts save significant amounts of energy, and are technologically feasible and economically justified. Therefore, DOE includes residential ballasts in the scope of coverage for this final rule.c. Ballasts That Operate Below Minimum ANSI Current LevelsAt the May 2011 public meeting, the General Electric Company (GE) commented that DOE's efficiency levels for programmed start (PS) ballasts assumed high efficiency filament cut-out at all arc powers. GE stated, however, that some low ballast factor (BF) PS ballasts operate at currents below minimum American National Standards Institute (ANSI) levels for T8 and T12 lamps and thus require filament heating to maintain lamp life. GE and NEMA noted that these ballasts would be unable to meet BLE requirements proposed in the April 2011 NOPR due to cathode heating, but would offer energy savings due to their relatively low power levels and use in conjunction with occupancy sensors. Thus, GE requested that these low BF ballasts be exempt from standards. (GE, Public Meeting Transcript, No. 43 at pp. 236, 238; NEMA, No. 47 at p. 6)
NEEA and NPCC recognized the operating limitations presented by these ballasts, but expressed concern over the lack of information about their fraction of shipments, the markets where they are most commonly sold, and their cost relative to other, more common ballast types designed to operate the same type and number of lamps. Specifically, NEEA and NPCC commented that these ballasts might be the kind of currently exempted product provided to the residential market, and that their continuing exemption could result in an increase in sales and accompanying loss in energy savings. (NEEA and NPCC, No. 44 at p. 4) The Joint Comment also highlighted the possibility of an increase in the use of these low BF ballasts in all applications if they were exempt from standards. They stated that the current small market share did not mean that shipments would not increase substantially in response to an exemption, thereby decreasing the potential energy savings due to the standards adopted by the rulemaking. (Joint Comment, No. 46 at pp. 2, 3)
DOE reviewed ANSI C78.81-2010 (17)
and determined that ballasts designed to operate 4-foot MBP T8 lamps are required to use some level of cathode heating when operating lamps at currents less than 155 milliamperes (mA). Through testing, DOE learned the BF of these ballasts was similar to or less than 0.7. This low BF (which affects light output) is a unique utility that might be removed from the market if these ballasts were held to the established standard level. DOE analyzed test data for 4-foot MBP T8 programmed start ballasts with average currents less than 155 mA to determine if there was a trend between low current and low efficiency. DOE determined that as current decreased, the BLE also decreased. DOE concluded that none of the PS ballasts tested with an average current of less than 140 mA were able to meet the max tech efficiency levels analyzed in the PS product class. Therefore, DOE is exempting these PS low-current ballasts from the standards adopted in this final rule.
DOE does not believe that an exemption for these ballasts will lead to an increase in their use because when current is reduced, light output is also reduced. Consumers have light output requirements and would not consider a ballast that does not meet such a requirement to be an adequate substitute. Reduced light output could also require additional lighting fixtures to be purchased in order to meet expected lighting levels. It is unlikely, however, that consumers would purchase additional fixtures due to high first cost. As a result, DOE establishes an exemption for these PS, low-current ballasts. DOE has determined that the threshold for the exemption will be set at the current levels indicated in its testing, 140 mA for 4-foot MBP ballasts.d. Other ExemptionsRadionic commented that DOE should consider exempting outdoor ballasts, cold weather ballasts, “all ballasts for less than 30 watts”, ballasts that have a normal power factor (18)
(a power factor equal to or greater than 0.6 and less than 0.9), and ballasts that are produced in small quantities for special applications. (Radionic, No. 36 at p. 1)
DOE notes that several of the ballasts mentioned by Radionic are already subject to standards. For example, because outdoor and cold weather ballasts, apart from sign ballasts, are already covered by current standards, DOE cannot exempt them from standards in this rulemaking due to anti-backsliding statutory provisions (discussed in section II.A). Similarly, DOE interpreted “all ballasts for less than 30 watts” as ballasts that operate total lamp arc powers less than 30 W. Some of these ballasts (such as ballasts that operate F34T12 lamps) are covered by current standards and cannot be exempted in this rulemaking. In general, DOE specifies efficiency levels using a power law equation that assigns BLE values as a function of total lamp arc power. In other words, the equation takes lower lamp arc power into account when assigning appropriate standard levels. Even though they operate lower wattage lamps, these ballasts still demonstrate significant potential energy savings and DOE test data shows they are capable of meeting the standard levels adopted by this final rule. Therefore, DOE will not exempt ballasts that operate total lamp arc powers less than 30 W in this final rule.
Ballasts with a normal power factor are classified as residential ballasts. DOE continues to cover residential ballasts as discussed in section III.A.2.b. For residential ballasts, as well as all other types listed above, Radionic didnot provide DOE with any specific information regarding ballasts produced in small quantities for special applications, or specific data indicating that these ballasts would be unable to meet any standards. DOE has looked at the market and has not identified any applications, other than those already defined, in which ballasts are unable to meet standards and would require an exemption. For all of the ballast types Radionic listed, DOE has determined that the adopted standard levels are technologically feasible and economically justified.3. Summary of Fluorescent Lamp Ballasts To Which DOE Extends CoverageWith the exception of the comments discussed previously in this section, DOE received no other input related to coverage of fluorescent lamp ballasts. In addition, DOE's revised analyses indicate that energy conservation standards for the ballasts for which DOE proposed coverage in the April 2011 NOPR are still technologically feasible, economically justified, and would result in significant energy savings. Therefore, in summary, this final rule extends coverage to the following fluorescent lamp ballasts:
(1) Ballasts that operate 4-foot medium bipin lamps with a rated wattage (19)
of 25W or more, and an input voltage at or between 120V and 277V;
(2) Ballasts that operate 2-foot medium bipin U-shaped lamps with a rated wattage of 25W or more, and an input voltage at or between 120V and 277V;
(3) Ballasts that operate 8-foot high output lamps with an input voltage at or between 120V and 277V;
(4) Ballasts that operate 8-foot slimline lamps with a rated wattage of 52W or more, and an input voltage at or between 120V and 277V;
(5) Ballasts that operate 4-foot miniature bipin standard output lamps with a rated wattage of 26W or more, and an input voltage at or between 120V and 277V;
(6) Ballasts that operate 4-foot miniature bipin high output lamps with a rated wattage of 49W or more, and an input voltage at or between 120V and 277V;
(7) Ballasts that operate 4-foot medium bipin lamps with a rated wattage of 25W or more, an input voltage at or between 120V and 277V, a power factor of less than 0.90, and are designed and labeled for use in residential applications; and
(8) Ballasts that operate 8-foot high output lamps with an input voltage at or between 120V and 277V, have an enclosure with an Underwriters Laboratories (UL) Type 2 rating, and are designed, labeled, and marketed for use in outdoor signs. (20)
The following ballasts are exempt from coverage:
(1) Additional dimming ballasts;
(2) Low frequency T8 ballasts that are designed, labeled, and marketed for use in EMI-sensitive environments and sold in packages of 10 or fewer;
(3) PS ballasts that operate 4-foot MBP T8 lamps and deliver on average less than 140mA to each lamp.B. Off Mode and Standby Mode Energy Consumption StandardsEPCA requires energy conservation standards adopted for a covered product after July 1, 2010 to address standby mode and off mode energy use. (42 U.S.C. 6295(gg)(3)) Because DOE is required by consent decree to publish a final rule establishing any amended standards for fluorescent lamp ballasts by October 28, 2011, (21)
this rulemaking is required to consider standby mode and off mode energy use. DOE determined that it is not possible for the ballasts at issue in this final rule to meet the off-mode criteria because there is no condition in which a ballast is connected to the main power source and is not already in a mode accounted for in either active or standby mode. In the test procedure addressing standby mode energy consumption, DOE determined that the only ballasts that consume energy in standby mode are those that incorporate an electronic circuit that enables the ballast to communicate with and be part of a lighting control interface (e.g., digitally addressable lighting interface (DALI) enabled ballasts). 74 FR 54445, 54447-8 (October 22, 2009). DOE believes that the only commercially available ballasts that incorporate an electronic circuit to communicate with a lighting control interface are dimming ballasts.
As discussed in the April 2011 NOPR, DOE did not expand the scope of coverage to include additional dimming ballasts. Therefore, the only covered dimming ballasts are the four products specified in 10 CFR 430.32(m)(5) that operate reduced-wattage lamps. DOE research has not identified any dimming ballasts currently on the market that operate these lamps because the fill gas composition of reduced-wattage lamps makes them undesirable for use in dimming applications. Because DOE is not aware of any other dimming products that are covered by existing standards, DOE was unable to characterize standby mode energy consumption. Therefore, DOE does not adopt provisions to address ballast operation in standby mode as part of the energy conservation standards that are the subject of this rulemaking.IV. General DiscussionA. Test Procedures1. BackgroundAs noted previously, manufacturers must use the test procedures for ballasts at 10 CFR part 430, subpart B, appendix Q to determine compliance with the currently applicable ballast efficacy factor standards. On March 24, 2010, DOE issued a NOPR in which it proposed revisions to these test procedures. 75 FR 14288. The principal change DOE proposed to the existing test methods was, in an effort to reduce measurement variation, to eliminate photometric measurements used to determine ballast efficacy factor (BEF). Instead, DOE proposed to use electrical measurements to determine ballast efficiency (BE), which could then be converted to BEF using empirically derived transfer equations. The proposed changes specified that the ballast operate a resistive load rather than a lamp load during performance testing. For consistency with previous methods, no changes were proposed for the measurement of BF (which required photometric measurements). The preliminary TSD for this rulemaking considered standards in terms of BEF, as determined by the methods proposed in the active mode test procedure NOPR.
After reviewing comments submitted in response to the active mode test procedure NOPR (75 FR 14287, March 24, 2010) and conducting additional research, DOE issued a supplemental NOPR (SNOPR) proposing a lamp-based ballast efficiency metric instead of the resistor-based metric proposed in the NOPR. 75 FR 71570 (November 24, 2010). The new metric, BLE, was equal to the total lamp arc power divided by ballast input power. DOE believed thislamp-based metric more accurately assessed the real-life performance of a ballast and also reduced measurement variation relative to the existing test procedure for BEF. DOE also proposed a method for calculating the BF of a ballast by dividing the measured lamp arc power on the test ballast by the measured lamp arc power on a reference ballast. In cases where reference ballast operating conditions were unavailable, the SNOPR provided a reference lamp power (specific to the ballast type) from an ANSI standard or from empirical results. The April 2011 NOPR for the standards rulemaking used the BLE procedures specified in the test procedure SNOPR to propose energy conservation standards.
The final rule for the active mode test procedure, which was published in theFederal Registeron May 4, 2011, adopted the BLE metric proposed in the SNOPR with a few modifications. 76 FR 25211. To account for the increase in lamp efficacy associated with high-frequency lamp operation versus low-frequency, DOE had proposed an adjustment to the BLE of low-frequency systems. DOE had proposed that low-frequency BLE be multiplied by 0.9 to account for the approximately 10 percent increase in lighting efficacy associated with high-frequency lamp operation. For the final rule, DOE assigned specific lamp operating frequency adjustment factors for each ballast type considered. The adjustment factors more accurately approximated the increase in lighting efficacy associated with high-frequency lamp operation. In addition, in the final rule, DOE did not adopt a BF measurement procedure because BF was no longer used to define product classes for energy conservation standards.
This final rule for energy conservation standards evaluates standards for ballasts in terms of the BLE metric adopted in the active mode test procedure. Appendix Q1 of 10 CFR part 430 Subpart B will be used to evaluate compliance with the standards adopted in this final rule. 76 FR 25211, 25213 (May 4, 2011)
DOE received comments in response to the April 2011 NOPR regarding the new fluorescent ballast testing procedure and BLE metric. Several stakeholders expressed support for the BLE metric. The Pacific Gas and Electric Company, Southern California Edison, the Southern California Gas Company, and San Diego Gas and Electric (hereafter the “CA Utilities”) commented that the new BLE metric is an improvement over the existing BEF metric because it allows for efficiency comparison across a wider range of ballasts. (CA Utilities, No. 45 at p. 1) NEEP and CA Utilities stated that the new BLE metric successfully simplifies testing requirements and enables the vast consolidation of product classes, which will make the compliance and enforcement processes easier. (NEEP, No. 92 at p. 3; CA Utilities, No. 45 at pp. 1-2) CA Utilities also approved of the new test procedure, commenting that they support the use of lamps to measure lamp arc power instead of sets of resistor banks designed to simulate lamps. CA Utilities stated that actual lamps, which have varying impedance based on power, more accurately represent real world loads on ballasts. They added that maintaining different sets of resistor banks at every ballast factor would have increased the testing burden for manufacturers. (CA Utilities, No. 45 at p. 2)
DOE also received several comments requesting clarification on the new test procedure. These comments are discussed in the following sections.2. Transfer FunctionGE asked if DOE would be creating transfer functions, similar to those proposed in the active mode test procedure NOPR, to convert BLE to BEF for marketing purposes. GE noted that as BEF will continue to be more relevant for consumers using lumens and system watts, manufacturers will continue to publish those numbers even though they will not test the ballasts with that metric. (GE, Public Meeting Transcript, No. 43 at p. 237) As discussed in section VII.D, to verify that no backsliding had occurred, DOE developed a method to convert BEF to BLE in order to compare current and newly adopted standards. However, DOE requires manufacturers to certify compliance in terms of the BLE metric only and therefore does not provide a transfer function for converting BLE to BEF for marketing purposes.3. Reference LampGE noted that it is not always clear what lamp should be used when testing a ballast and requested clarification on this matter. (GE, Public Meeting Transcript, No. 43 at pp. 236-7) DOE notes that Table A in the ballast test procedure, Appendix Q1 of 10 CFR part 430 Subpart B, provides the appropriate lamp wattage, diameter and base to use in testing for each covered ballast type. For example, the first row of Table A shows that ballasts “that operate straight-shaped lamps (commonly referred to as 4-foot medium bipin lamps) with medium bipin bases and a nominal overall length of 48 inches” should be tested with 32W T8 MBP lamps.4. Total Lamp Arc PowerThe People's Republic of China (P.R. China) noted that in the April 2011 NOPR, the term “total lamp arc power” was not well-defined. They noted that ANSI C78.81-2010 specifies “arc wattage” for various fluorescent tube lamps but does not define “total lamp arc power.” Furthermore, while the test procedure SNOPR included a definition for “total lamp arc power,” it also included a table that listed a low and/or high frequency “reference lamp arc power” for each covered ballast type. 75 FR 71570, 71592 (November 24, 2010). P.R. China indicated that these terms caused confusion regarding the appropriate value to be used when calculating the efficiency standard. Therefore, they suggested DOE clarify the specific value of “total lamp arc power” and use consistent terminology to avoid confusion. (P.R. China, No. 51 at p. 3-4)
CA Utilities and NEEA and NPCC agreed that it was unclear which arc power should be used to calculate the applicable BLE standard. CA Utilities recommended that DOE require manufacturers to use the average lamp arc power of the tested sample to determine the BLE for a given model. (CA Utilities, No. 58 at p. 4; NEEA and NPCC, No. 59 at p. 3)
DOE notes that reference lamp arc power refers to the arc wattage listed in ANSI C78.81-2010 and, as shown in that standard, can vary depending on whether the reference ballast operates at low or high frequency settings. (22)
These values were provided in the test procedure SNOPR for the purposes of calculating ballast factor. However, because the test procedure final rule did not adopt a procedure for calculating ballast factor, reference lamp arc powers are no longer relevant. Total lamp arc power is a measured, not listed, value and is evaluated according to the recently adopted test procedure.
DOE also notes that 10 CFR 429.26 does not currently reflect the new ballast luminous efficiency metric. DOE plans to consider certification procedures in upcoming rulemakings related to compliance certification and enforcement. (23)
For this final rule, DOEcomputed the reported ballast luminous efficiency and total lamp arc power assuming the ballast basic models would be certified in the following manner. To certify compliance, manufacturers would calculate the total lamp arc power and BLE for each sample tested according to 10 CFR 430, Subpart B, Appendix Q1. They would then average the total lamp arc power of each sample and input that average into the appropriate energy conservation standard efficiency level. The output of that equation dictates the minimum BLE that the reported BLE for each basic model must meet or exceed. To calculate the reported BLE for each basic model, manufacturers would follow the provisions laid out in 10 CFR 429.26(a)(2)(ii).B. Technological Feasibility1. GeneralIn each standards rulemaking, DOE conducts a screening analysis based on information it has gathered on all current technology options and prototype designs that could improve the efficiency of the products that are the subject of the rulemaking. As the first step in such analysis, DOE develops a list of technology options for consideration in consultation with manufacturers, design engineers, and other interested parties. DOE then determines which of these means for improving efficiency are technologically feasible. DOE considers technologies incorporated in commercially available products or in working prototypes to be technologically feasible. 10 CFR 430, subpart C, appendix A, section 4(a)(4)(i).
Once DOE has determined that particular technology options are technologically feasible, it further evaluates each of them in light of the following additional screening criteria: (1) Practicability to manufacture, install, or service; (2) adverse impacts on product utility or availability; and (3) adverse impacts on health or safety. For further details on the screening analysis for this rulemaking, see chapter 4 of the final rule TSD.2. Maximum Technologically Feasible LevelsWhen DOE considers an amended standard for a type or class of covered product, it must determine the maximum improvement in energy efficiency or maximum reduction in energy use that is technologically feasible for that product. (42 U.S.C. 6295(p)(1)) Accordingly, DOE determined the maximum technologically feasible (“max tech”) ballast efficiency in the engineering analysis, using the design options identified in the screening analysis (see chapter 5 of the final rule TSD).
As a first step to identifying the max tech efficiency level, DOE conducted testing of commercially available ballasts. DOE was unable to identify working prototypes that had a higher efficiency than the tested products. Therefore, DOE has determined that TSL 3B, which is based on the most efficient commercially available ballasts tested, represents the highest efficiency level that is technologically feasible for a sufficient diversity of commercially available products (spanning several ballast factors, number of lamps per ballast, and types of lamps operated) within each product class. The max tech efficiency levels require the use of electronic ballasts with improved components (such as high efficiency transformers, diodes, capacitors, and transistors). The max tech levels also require IS instead of RS ballasts, or some form of cathode cut-out technology for PS ballasts. Table IV.1 presents the max tech levels for each product class.
