### 5F-1 APPENDIX 5F. ADVANCED TECHNOLOGY SCENARIO

5F.1 INTRODUCTION

In the notice of proposed rulemaking (NOPR), the U.S. Department of Energy ( DOE ) analyzed efficiency levels that could be met by a sufficient diversity of c ommercially available

ballast s. In this a ppendix, DOE considers an alternative scenario in which manufacturers are assumed to have the capability to redesign certain representative ballast types to be more

efficient than the product s currently available in the market. This alternative technology scenario

affects all representative ballast types in the instant start (IS) and rapid start (RS) product class

.

5F.2 ASSUMPTIONS

During interviews, manufacturers indicated that ballasts that operate similar lamp powers often share similar topologies and components. Thus, it follows that their efficiencies should be

similar as well. This information led DOE to develop efficiency levels using a power

- efficiency relationship

. An analysis of test data revealed this relationship to be most accurately characterized by an equation relating ballast luminous efficiency (BLE) to the natural log oflamp arc power. However, within the IS and RS product class, DOE noticed that several higherpower ballasts exhib ited higher efficiencies than those predicted by the power

- efficiency equation. In the NOPR notice, DOE did not evaluate max tech at a level equivalent to these products because DOE could not confirm it to be technologically feasible for a sufficient

diver sity of ballasts (spanning several ballast factors, number of lamps per ballast, and types of lamps operated) . However, in this appendix, DOE is assuming that a max tech level based on these high efficiency ballasts is technologically feasible for a suffic ient diversity of products and therefore analyzes an EL4 for the IS and RS product class.

5F.3 METHODOLOGY

The methodology used to develop the manufacturer selling prices (MSPs ) and efficiency

levels (ELs) for the advanced technology scenario remains the same a s that presented in c hapter 5 of the NOPR technical support document ( TSD ). With the exception of EL4, this scenario

maintains the same efficiency level equations and representative units (with their corresponding characteristics) as analyzed in the NOPR n otice for the IS and RS product class.

5F.3.1 Development of the EL4 Equation

For the advanced technology scenario, DOE followed the same methodology outlined in the NOPR notice and chapter 5 of the NOPR TSD. In general, DOE plotted all of the test data

and found that a logarithmic relationship best modeled the observed trend between total lamp arc power and BLE. Next, DOE plotted curves that aligned with certain key divisions in product offerings using an equation of the form: BLE = coefficient * ln (t otal lamp a rc power) +

constant. DOE adjusted the coefficient and constant to delineate different efficiency levels.

### 5F-2 To develop EL4, DOE fitted a logarithmic relationship between total measured lamp arc power and efficiency to the most efficient 4 -lamp MBP IS and RS and 8- foot slimline ballasts

tested. The EL4 equation just allow s the most efficient commercially available 2- lamp 8 -foot

slimline ballast s and 4-lamp MBP IS and RS ballasts . EL4 is also met by the most efficient 1

- and 2- lamp 8

- foot slimline and 4- lamp high ballast factor MBP IS ballasts. The table below presents the equation for the new EL4, along with the existing equations for EL1, EL2, and EL3. In addition, the figure below shows all of the efficiency levels plotted against all of the ballasts

tested in the IS and RS product class.

5F.3.2 Representative Units

Although the EL4 equation was based on commercially available data, not all of the representative ballast types had a commercially available unit at this level. If a commercially available unit existed, as was the case for the 2- lamp 8

- foot slimline and 4- lamp MBP representative ballast types, the characteristics of the representative units were based on the tested performance of the ballast. However, for the 2- la mp MBP IS and RS (residential and

### 5F-3 commercial) representative ballast type, DOE did not identify any commercially available units

that met EL4 . Thus, DOE had to calculate the relevant technical characteristics , such as ballast

factor (BF) , input power, and ballast luminous efficiency (BLE).

To develop these theoretical units , DOE used both the EL4 equation and the characteristics of the representative unit s that met EL3

. DOE assumed that representative units

for the 2

- la mp MBP IS and RS (residential and commercial) ballast types that met EL4 would

have the same BF and operate the same total lamp arc power as the representative units at EL3.

Next , DOE evaluated the EL4 equation using the total lamp arc power assigned to the representative unit at EL3. This yielded the representative BLE for EL4. Then , DOE divided the total lamp arc power at EL4 by the calculated BLE at EL4 to determine the representative inpu t power. Using these values (input power, BF, and BLE) DOE calculated additional technical values (system lumen output, normalized input power, etc.) for comparison with representative

units at other efficiency levels

.

5F.3.3 Manufacturer Selling Prices

In addit ion to determining the technical information for all representative units at EL4, DOE also had to calculate the manufacturer selling price. As described in chapter 5 of the TSD, DOE developed prices using three main inputs: teardown data, blue book prices, and

manufacturer

- provided MSPs. In general, DOE used a combination of the teardown- and blue book-sourced prices throughout the analysis and used the aggregated manufacturer-supplied MSPs for normalization and comparison purposes.

For the advanced technology scenario, DOE needed to determine MSPs at EL4 for the four representative ballast types in the IS and RS product class. For the 8- foot slimline representative ballast type, DOE used blue book data for the commercially available unit to
estimate an MS P at EL4 (using the method described in chapter 5 of the NOPR TSD for blue book-sourced MSPs). Alt hough a commercially available unit was identified for the 4- lamp MBP representative ballast type, DOE did not identif y any blue book data or sufficient retai l data to develop an MSP. Similarly, DOE did not possess either type of price data for 2- lamp MBP IS and RS (residential and commercial) ballasts because neither type was commercially available. Thus, for these three representative ballast types, DOE emplo yed a scaling methodology. DOE multiplied the MSP at EL3 by the ratio of the 8- foot slimline MSP at EL4 to the MSP at EL3.

The equations identified for EL1, EL2, and EL3 have not changed from those presented in chapter 5 of the NOPR TSD. H owever EL4 represents the new efficiency level analyzed for the advanced technology scenario. EL4 affects both of the baseline ballasts a nd represents the

### 5F-4 maximum technologically feasible level for this representative ballast type . Though DOE did not

identif y commercially available 2

- lamp medium bipin ( MBP ) IS and RS ballasts that meet EL 4,

DOE believes ballast s could be designed and manufa ctured to meet th is new max tech level.

Ballasts at this level w ould use slightly better components and circuit designs than tho se ballasts that just meet EL3.

### 5F-5 5F.4.2 Results

Table 5F.4.1 and Table 5F.4 .2 present the engineering characteristics of the representative 2

- lamp MBP IS and RS ballast designs used in the engineering analysis and subsequent analyses. In general, for the 2- lamp MBP IS and RS representative ballast type, ballasts at higher efficiencies can operate at multiple input voltages and have a lower THD, similar BF, and similar PF compared

to the baseline ballast designs. For the advanced technology scenario, DOE used the same ballast prices for the baseline, baseline/EL1, EL2, and EL3, and the same lamp prices as those presented in chapter 5 of the NOPR TSD. To develop a ballast price at EL4, DOE used the scaling technique described in section 5F.3.3 . T he retail price of the replacement lamps reflects the number of lamps in the system (e.g., if it is a 2

- lamp system the retail price is the price of two lamps).

Table 5F.4.1 presents the engineering characteristics of the ballast replacement options for the baseline F32T8 system. Because

the ballast factors of the standards- case systems are slightly lower than the baseline system, the normal ized input power is slightly higher than the measured input power. If a direct substitution is made, mean lumen output does not change by more than eight percent relative to the mean lumen output of the baseline system.

### 5F-6 Table 5F.4.2 presents the engineering characteristics of the ballast replacemen t options for the baseline F34T12 system in the

2- lamp MBP IS and RS representative ballast type. The representative F34T12 baseline ballast has a relatively low BF of 0.80. Typical F32T8 replacements have a higher ballast factor which results in increased total lumen output. If a direct substitution is made, mean lumen output does not change by more than 15 percent relative to the mean lumen output of the baseline system.

### 5F-8 5F.5.2 Results

The tables below present the engineering characteristics of the representative residential ballast designs used in the engineering analysis and subsequent analyses. In general, for the residential representative ballast type, ballasts at higher efficiencies can op erate at 120 volts (V) and have a slightly higher ballast factor compared to the baseline ballast designs. For the advanced technology scenario, DOE used the same ballast prices for the baseline, baseline/EL1, and EL3, and the same lamp prices as those presented in chapter 5 of the NOPR TSD. To develop a ballast price at EL4, DOE used the scaling technique described in section 5F.3.3

. The retail price of the replacement lamps reflects the number of lamps in the system (e.g., if it is a 2

- lamp system the retail price is the price of two lamps).

The first table presents the engineering characteristics of the ballast replacement options for the baseline F32T8 system.

Because the ballast factors of the standards- case systems are sl ightly higher than the baseline system, the normalized input power is slightly lower than the measured input power. If a direct substitution is made, mean lumen output does not change by more than seven percent relative to the mean lumen output of the base line system.

The table below present s the engineering characteristics of the representative 4 -lamp MBP ballast designs used in the

In general, for the 4- lamp MBP IS and RS representative ballast type, ballasts at higher efficiencies can operate at multiple voltages and have a similar BF and PF as the baseline ballast designs. For the advance d technology scenario, DOE used the same ballast prices for the baseline/EL2 and EL3 units and the same lamp prices as those presented in chapter 5 of the NOPR TSD.

Table 5F.6.1 presents the engineering characteristics of the ballast replacement option s for the baseline F32T8 system. Because the BF of EL3 is slightly lower than the baseline system, the normalized input power is higher than the measured input power. By contrast, the BF at EL4 is sligh tly higher than the baseline system, so the normalized input power is lower than the measured input power. If a direct substitution is made, mean lumen output does not change by more than two percent relative to the mean lumen output of the baseline system.

The tables below present the engineering characteristics of the representative 8

- foot slimline ballast designs used in the engineering analysis and subsequent analyses. In general, ballasts at higher efficiencies operate multiple voltages and have simi lar ballast factors and power factors compared to the baseline designs. For the advanced technology scenario, DOE used the same MSPs for the baseline/EL1, baseline/EL2, and EL3 units and the same lamp prices as those presented in chapter 5 of the NOPR TSD. To develop a ballast price at EL4, DOE used the blue book (also described in chapter 5 of the NOPR TSD). The retail price of the replacement lamps reflects the number of lamps in the system (e.g., if it is a 2

- lamp system the retail price is the price of two lamps).

Table 5F.7.1 presents the engineering characteristics of the ballast replacement options for the baseline F96T12/ES system.

Because the ballast factors of the more efficient replacements are slightly lower than the baseline system, the normalized input power is higher than the measured input power. If a direct substitution is made, mean lumen output does not change by more than fou r percent relative to the mean lumen output of the baseline system.

### 5F-14 Table 5F.7.2 presents the engineering characteristics of the ballast replaceme nt options for the baseline F96T8 system in the 8-

foot slimline representative ballast type. Because the ballast factors of the standards- case systems are slightly lower than the baseline system, the normalized input power is slightly higher than the measu red input power. If a direct substitution is made, mean lumen output does not change by more than two percent relative to the mean lumen output of the baseline system.

### 5F-16 5F.8 MSP COMPARISON

As described in c hapter 5 of the NOPR TSD, DOE developed MSPs using three main inputs. These inputs included physical teardown analysis, blue book manufacturer price lists, andconfidential manufacturer supplied data. DOE used an average of blue book- and teardownbased MSPs when developing the final MSP to be assigned to an EL. Manufacturer MSPs were used for normalization and verification purposes. DOE chose to use the blue book and teardown data because this data was available in the public domain allowing for verification by DOE and interested parties. Manufacturer data is less verifiable by interested parties, so DOE decided not to use it as the primary data source for developing MSP data. Furthermore, manufacturer data was not available for all ELs in all representative balla st types. However, Table 5F.8.1 lists the prices based on each information source for each representative ballast type. All manufacturer

supplied MSP data included in these figures are aggregations of multiple data points. DOE als o presents plots for the three representative ballast types with the most complete data.
