History & Rulemaking Process3Alternative Methods Considered4Proposal: Resistor-BasedBE Correlated to BEF2Existing Test Procedure14 | Building Technologies Programeere.energy.govExisting Test Procedure•The existing test procedure calculates ballast efficacy factorbased on ANSI C82.2-1984•Proposed amendments to the existing test procedure–Method of measurement ANSI C82.2-1984 → ANSI C82.2-2002–For ballast operating conditions, replace ANSI C82.1-1997 with:ANSI C82.1-2004 forlow-frequency ballastsANSI C82.11-2002 for high-frequency ballastsIssue 2:DOE seeks comment on the updates

Variation–Reference lamp measured power can deviate up to 2.5% of therated lamp power, impacting input power and BEFMeasurement Variation–Testing facility ambient temperature variation–Lamps respond differently to thechange between low- and highfrequency operation, affecting BF measurementLimitations of BEF–BEF can not be used to directly compare ballasts that operatedifferent wattage lamps or numbers of lamps16 | Building Technologies Programeere.energy.govEfficiency Metric•Several commenters suggestedchanging the metric fromBEF to ballast efficiency(BE) or relative system efficacy(RSE)•DOE will continue setting standards using BEF to beconsistent with existing energy conservation standards,42 USC 6295(g)(5), (g)(8)•DOE proposes to measure ballastefficiency using a ballastresistor system and tocorrelate BE to BEFBECorrelationsBEF17 | Building Technologies Programeere.energy.govIssue for CommentIssue 1:DOE seeks comment on all aspects of the existingtest

Process3Alternative Methods Considered4Proposal: Resistor-BasedBE Correlated to BEF2Existing Test Procedure19 | Building Technologies Programeere.energy.govAlternatives–Improved Light Output Method•Much of the variation in the ANSIbased, light output testprocedure can be reduced byfurther specifying some keyfactors:–Lamp measured power, rated wattage ± 1.0%–Testing facility ambient temperature, 25oC ± 0.5oC–Operate the reference lamp at constant voltage–Use electrode heating in the referencecircuit for MBP, Mini-BP,and RDC lamps–Use light output measurementsfor the determination of ballastfactor for all ballasts and all lamps–For a given ballast, specifythe type of lamp and number oflamps to be operated during testing20 | Building Technologies Programeere.energy.govAlternatives–Improved Light Output Method•Potential Advantages–Familiar procedure to industry–Ballast is operating its natural load–Reduced measurement variation due to tighter tolerances•Potential Disadvantages–Tighter tolerances may be burdensome–The effects of lamp manufacturing variation are not eliminatedIssue 5:DOE seeks comment from interested parties who do notsupport the proposed resistor-based ballast efficiency method on theimproved light-output-based test procedure.21 | Building Technologies Programeere.energy.govAlternatives–Lamp-based BEcorrelated to BEF•The NEMA Ballast Technical Committee drafted a testprocedure for the measurement of ballast efficiency (BE)using a lamp and ballast system•Test Methodology1.Season the lamp for 12 hours2.Stabilize the lamp and ballast system for no more than 1 hour,until steady-state is reached3.Take input and output power measurements simultaneously•Convert BE to BEF using a transfer equation22 | Building Technologies Programeere.energy.govAlternatives–Lamp-based BEcorrelated to BEF•Potential Advantages–Most accurately characterizesthe real life operating conditions ofa lamp and ballast system.–The ballast load accounts for the fact that a lamp is a dynamicload–Less sensitive to lamp power and environmental conditions thanthe light output based method•Potential Disadvantages–Lamp to lamp variation may still be an issueIssue 5:DOE seeks comment from interested parties who do notsupport the proposed resistor-based ballast efficiency method on thelamp-based BE correlated to BEF method.23 | Building Technologies Programeere.energy.govAlternatives–Relative System Efficacy (RSE)•RSE uses the same test methodas the existing test procedure•RSE normalizes BEF for ballasts ofdifferent total rated lamppower•Advantages–RSE is potentially more comparableacross different ballast types–Uses a familiar test procedure•Disadvantages–RSE is based on the same varied inputs as the existing testprocedure for BEFIssue 5:DOE seeks comment from interested parties who do notsupport the proposed resistor-based ballast efficiency method on RSEtest procedure or any other procedure they believe is appropriate.24 | Building Technologies Programeere.energy.govPresentation Overview1Regulatory History & Rulemaking Process3Alternative Methods Considered4Proposal:

DOE seeks comment on DOE’s approach to uselight output-based measurement to determine ballast factor and theresulting variation in ballast factor due to lamp manufacturingvariations. DOE also requests comment on impact of this variation inBF on the calculated BEF (according to the proposed test procedure).Issue 8:DOE seeks comment on the effect of DOE’s approach of usinga single resistor value for measuring ballasts of all ballast factors (for aparticular ballast) and correlating measured BE to correlated BEFusing transfer equations specific to ballast factor bins.29 | Building Technologies Programeere.energy.govTest MeasurementsBE•Electrical measurements taken within 1 minute of energizing–Input voltage, current, power–Output power•Universal voltage ballasts should be tested at the followinginput voltages:–277 volts for commercial ballasts–120 volts for residential and cold-temperature sign ballastsBF•Measure BF according to ANSI C82.2-2002 with the followingamendments discussed in theimproved light output basedmethod:–Clarifications to BF measurement–Operate the ballast with the most common wattage lamp and themaximum number of lamps a ballast is designed to operate30 | Building Technologies Programeere.energy.govTransfer Equations - Overview•DOE tested BE and BEF for multiple ballasts in key productclasses•Found a linear relationship between BE and BEF•Scaled relationships to product classes not directly tested2-lamp, 32W MBP T8, Normal BF, IS/RS
