Theonly commercially available product that meets this level uses aproprietary silverized reflector. However, DOE believes it can alsobe achieved by using advanced IR coatings.DOE invites comments on the efficacy levels considered for IRL, inparticular EL1 and EL5.DOE also invites comments on the performance characteristics (e.g.lumen output, lifetime, wattage) established for IRL model lamps used inthe engineering analysis – specifically, the properties of the improvedhalogen IRL that uses xenon as a fill gas (the lamp established for EL 1)IRL Efficacy Levels(Issues #6, #7)Engineering Analysis26Scaling to Other Fluorescent Lamp Product Classes:Product Classes with CCT > 4500K(Issue #9)DOE needed to scale from a representative product class to thecorresponding fluorescent product class with CCT > 4500KDOE decided to establish a separate scaling factor for each EL andproduct classAfter analyzing catalog data for the lumen output of lamps with a CCTgreater than 4,500K and less than 4,500K, DOE found NEMA’srecommendation to be consistent with commercially availableproduct and adopted these efficacy reductions.Reductions range from 2.6% to 7.2%Engineering AnalysisDOE invites comments on the methodology used to scale efficacy levelsfrom representative product classes to high CCT lamps for GSFL27Scaling to Other Fluorescent Lamp Product Classes:2-Foot U-shaped with CCT≤4500K(Issue #9)DOE used manufacturer catalog data to develop efficacy levels for Ushaped lamps with similar technology impact as 4-foot MBP efficacylevelsDOE then used compliance reports to determine the efficacy at whichcommercially-available lamps would comply.Due to limited compliance report data, where data was unavailable,DOE used the same percentage efficacy reductions for U-shapedlamps as it did for 4-foot MBP lamps.Reductions from 4-foot MBP efficacy levels range from 5.6% to 7.7%Engineering AnalysisDOE invites comments on the methodology used to scale efficacy levelsfrom representative product classes to 2-foot U-shaped lamps28Scaling to Other IRL Product Classes:Modified Spectrum Lamps(Issue #9)DOE identified several IRL with modified-spectrums and comparedtheir performance with standard (i.e., non modified-spectrum)lamps.DOE assessed the efficacy differences between standard andmodified spectrum IRL by measuring the efficacies of commerciallyavailable IRL.By analyzing this test data, DOE established that a reduction of19% from the standard-spectrum efficacy levels would beappropriate for modified spectrum IRL.DOE invites comments on the methodology used to scale efficacy levelsfrom representative product classes to modified spectrum lamps.Engineering Analysis29Scaling to Other IRL Product Classes:Lamps with Smaller Diameters(Issue #9)A smaller diameter IRL has an inherently lower optical efficacy thana larger diameter lamp given a similar filament size.To determine an appropriate scaling factor for IRL with diametersless than or equal to 2.5 inches, DOE examined the inherentefficacy differences between the PAR20 lamp and its PAR30 orPAR38 counterpart by comparing catalog efficacy data of eachlamp type from several lamp manufacturers.In its analysis, DOE found thatthe reduction in efficacy causedbythe reduction in lamp diameter was approximately 12% for IRL.Engineering AnalysisDOE invites comments on the methodology used to scale efficacy levelsfrom representative product classes to smaller diameter lamps.30Scaling to Other IRL Product Classes:Higher Voltage Lamps(Issue #9)Lamps rated at 130V use different test procedures than lamps ratedat 120VDOE derived an efficacy scaling factor which would result inequivalent performance of both classes of IRL when operatingunder the same voltage conditionsDOE determined that a lamp operating at 130V would be 15% moreefficacious than a lamp of a similar wattage operating at 120V.Engineering AnalysisDOE invites comments on the methodology used to scale efficacy levelsfrom representative product classes to higher voltage lamps.31Request for Additional CommentsDOE invites comments on any other issues pertaining to theEngineering Analysis.Engineering Analysis32NOPR Analyses Flow DiagramEngineeringAnalysisLife-CycleCost &PaybackPeriodAnalysesNationalImpactAnalysisReviseANOPRAnalysesTrialStandardLevelsConsumerSubgroupAnalysisManufacturerImpactAnalysisUtilityImpactAnalysisEmploymentImpactAnalysisEnvironmentalAssessmentRegulatoryImpactAnalysis33Life-Cycle Cost and Payback Period AnalysesPurpose•To analyze the economic impacts ofpossible standards on individualconsumersApproach•Life-Cycle Cost (LCC) calculated forall baseline lamps and their higherefficiency alternatives in each productclass in order to characterize theeconomic impacts on each type of consumer•Various events that trigger the purchasing of a lamp are considered•Each product class analyzed in relevant sectors: commercial, industrial, and/orresidential•At some standard levels, there are multiple pathways to save energy (e.g.,reduced-wattage lamps or lamp and ballast combinations with reduced systempower). For these levels, a rangeof LCC results are presented.Life-Cycle Cost Analysis34Why Do Consumers Buy Lamps?Various events that trigger the purchasing of a lamp involve differenteconomics. DOE analyzes five such events:Lamp Failure- a lamp fails and must be replaced.Standards-Induced Retrofit- an increase in the efficacy standardprompts end-users to retrofit lamps and ballasts where, in the base case,they would otherwise only replace the lamp; only for T12 base case.Ballast Failure- an existing ballast fails and the consumer purchases anew lamp and ballast.Ballast Retrofit– consumers who were going to voluntarily retrofit theirexisting lamp and ballasts do so, and at certain ELs are impacted bybeing forced to a higher standard.New Construction and Renovation- all the new fixture installations wherethe lighting design will be new or can be completely reconfigured.Life-Cycle Cost Analysis;;;;Presented inthe NOPR35Key Inputs to LCCLife-Cycle Cost AnalysisInputDescriptionConsumer Product Price Applied discounts to manufacturercatalog (“blue-book”) pricing.Sales TaxDerived from the Sales Tax Clearinghouse.Installation CostLabor rates from RS Means and U.S Bureau ofLabor Statistics.Labor times from 2000 Ballast Rule and RS Means.

In thissituation there is no lamp failure event.To model lamp replacements, DOE used high operating hours (1,210hours/year) resulting in a lamp lifetime of 12.5 years. The replacementlamp has on average 2.5 years of useful life before the ballast orfixture is replaced.DOE invites comments on the choice of ballast lifetimes used in thecommercial, residential, and industrial sectors and the operating hoursfor GSFL in the residential sector.Life-Cycle Cost Analysis38GSFL LCC and Installed Cost Results(4-foot MBP operating in the Commercial Sector)Consumers canoften achievegreater savingsby voluntarilypurchasing athigher efficiencylevels.Life-Cycle Cost AnalysisRequiring theretrofit of a ballastat EL4 and EL5results in largeincreasedinstallation costs.39GSFL LCC and Installed Cost Results(4-foot MBP residential)Life-Cycle Cost AnalysisRequiring theretrofit of aballast at EL4and EL5 resultsin largeincreasedinstallationcosts.40IRL LCC and Installed Cost ResultsLife-Cycle Cost Analysis41Request for Additional CommentsDOE invites comments on any other issues pertaining to Life-Cycle Costand Payback Period Analyses.Life-Cycle Cost Analysis42NOPR Analyses Flow DiagramEngineeringAnalysisLife-CycleCost &PaybackPeriodAnalysesNationalImpactAnalysisReviseANOPRAnalysesTrialStandardLevelsConsumerSubgroupAnalysisManufacturerImpactAnalysisUtilityImpactAnalysisEmploymentImpactAnalysisEnvironmentalAssessmentRegulatoryImpactAnalysis43PurposeNational Impact AnalysisShipments Analysis•To estimate lamp shipments and the product mix of the stock over time (2012-2042) in the base case and standards case.National Impact Analysis•To estimate the National Energy Savings (NES) from GSFL and IRL efficacystandards at different levels.•To estimate the national economic impact on the nation (or the Net PresentValue (NPV)) from GSFL and IRL efficacy standards at different levels.44Estimate base-case shipment forecasts (2012-2042)•Develop shipment models thataccount for shipments due to:– Lamp Replacements– Ballast Replacements (only GSFL)– Fixture Replacement (only GSFL)– Renovation– New Construction•Historical shipments used to generateinitial lamp stocks and to calibrateshipments model.•Included base-case shipmentscenarios to account for the penetration of otherlighting technologies (e.g., LED, R-CFL,CMH) into the GSFL and IRL markets•Established market-share matrices to characterize theproduct distribution of theshipments and stock.Estimate standards-case shipments forecasts (2012–2042)•Developed with same data as used to estimate base-case forecasts.•Included several standards-case scenariosto model possible consumer responseto standards.ApproachNational Impact Analysis45Growth Rates(Issue #11)DOE invites comments on the growth rates used in the residential sectorGSFL and IRL shipments analysis.Forecasted growth in commercial and industrial floor space andresidential buildings•Used AEO 2008 for commercial floor space and residential building growthforecasts•Used Manufacturer Energy Consumption Survey (MECS) historical growth tocalculate the industrial sector floor space growth.Accounted for historical trends in number of lamps per residentialhousehold•Used a California study to estimatethe average number of GSFL and recessedcans in homes constructed from 2001 to 2005•Based on distributions of home age andbuilding growth, DOE estimated theaverage number of GSFL and recessedcans in homes from 2005 to 2042.•Average residential growth rates – GSFL: 1%; IRL: 2.6%National Impact Analysis46Emerging Technologies(Issue #11)DOE invites comments on the market penetration of emergingtechnologies in the GSFL and IRL shipments analysis.To account for the market penetrationof other lighting technologies intothe GSFL and IRL markets, DOE modeled two base-case shipmentscenarios:•Existing Technologies – forecasts the penetration of technologies that are currentlyavailable and have reached maturation in terms of price and efficacy.•Emerging Technologies - forecasts the penetration of maturetechnologies andthose that are still undergoing significant changes in price and efficacy.Methodology to establish market penetration forecasts•Estimated price andperformance forecasts of LEDs and CMH.•Calculated payback period of LEDs, CMH,and R-CFL compared to GSFL and IRL•Used payback period and marketpenetration relationships to develop forecasts.Existing Technologies Additional Emerging TechnologiesGSFLGSFL (including T5) LED, CMHIRLIRL, R-CFLLED, CMHNational Impact Analysis47GSFL Shipments: 4-foot MBP4-foot T8 MBP shipments grow due tonew construction and retrofitting of 4-foot T12 and 8-foot T12 SP Slimline systems2000 Ballast Rule effectively eliminatesthe sale of 4-foot T12 MBP magneticballasts causing T12 lamp shipments todecline.
