### APPENDIX 7A ADDITIONAL END

- USER PRICE RESULTS

7A.1 INTRODUCTIONBecause fluorescent lamps operate on a ballast in practice, DOE analyzed lamp-andba llast systems in the engineering analysis. Therefore, in addition to developing end-user prices for lamps, the U.S. Department of Energy ( DOE ) also determined end-user prices for ballasts. The se ballast prices were used as inputs in the life-cycle cost (LCC) analysis and the national impact analysis (NIA). This appendix presents the methodology DOE followed and the resulting fluorescent lamp ballast end-user prices.

7A.2 METHODOLOGY To determine the end-user ballast prices in this rulemaking, DOE utilized information from the recent rulemaking for fluorescent lamp ballasts, finalized in 2011 (hereafter the “2011 Ballast Rule”). 76 FR 70548 (Nov. 14, 2011 ). In the 2011 Ballast Rule, DOE performed teardowns and a manufacturer markup analysis to develop manufacturer selling prices (MSPs) for representative ballast designs. DOE then applied distribution channel markups to derive enduser prices. See chapters 5 and 7 from the technical support document (TSD) for the 2011 Ballast R ule for more information. a 

### For this rulemaking, DOE utilized the end-user prices from the 2011 Ballast Rule to determine prices for replacement ballasts. Because the fluorescent ballast prices de veloped in the 2011 Ballast Rule were presented in 2009$, DOE converted the end-user prices to 2011$ by multiplying the 2009 prices by the ratio of the 2011 Consumer Price Index (CPI) to the 2009 CPI.

DOE analyzed fixed light output ballasts in the engineering analysis and dimming ba llasts in a lighting controls sensitivity. DOE developed different prices for each ballast type.

7A.2.1 F ixed Light Output BallastsAs stated in chapter 5 of this preliminary TSD, for this rulemaking, DOE analyzed lampa nd -ballast systems with the same starting method and number of lamps as those analyzed in the 2011 Ballast Rule. In addition, because a ll ballasts selected by DOE comply with the standards adopted by the 2011 Ballast Rule, DOE assumed the prices of the representative ballasts in this rulemaking would be the same as the prices of the representative ballast units at the adopted

e fficiency level in the 2011 Ballast Rule.

Although DOE analyzed normal ballast factor (BF) ballasts as representative in the 2011 Ballast Rule, DOE also analyzed low BF ballasts in this rulemaking. Based on a review of blue book va lues and manufacturer feedback, DOE found that, in general, ballast prices for low and normal BF ballasts are very similar. Because the low BF replacement ballasts meet the efficiency leve l adopted by the 2011 Ballast Rule and DOE determined that low BF ballasts have the same

### prices as normal BF ballasts, DOE utilized the same end-user pricing for low BF ballasts as the

re presentative ballast units at the efficiency level adopted in the 2011 Ballast Rule.

7A.2.2 Dimming Ballasts Because most dimming ballasts are exempt from energy conservation standards, b 

### DOE did not analyze these ballasts in the 2011 Ballast Rule. Therefore, it was necessary to develop
pr ices for the dimming ballasts analyzed in the lighting controls scenario of this rulemaking (s ee

a ppendix 6A of this TSD for further details on the lighting control scenario). To determine prices for dimming ballasts, DOE compared the blue book prices of dimming ballasts to comparable fixed light output ballasts and develop ed a scaling factor to apply to the end-user prices of fixed light output ballasts developed in the 2011 Ballast Rule.

For the product classes analyzed in the lighting controls scenario ( i.e. , 4-foot medium bipin (MBP), 4-foot T5 miniature bipin (MiniBP) standard output ( SO ) , and 4-foot T5 MiniBP high output ( HO ) lamps in the commercial and industrial sectors), DOE matched commercially available fixed light output ballasts with a comparable dimming ballast offered by the same manuf acturer. DOE considered ballasts with similar specifications, including starting method, maximum number of lamps operated, and efficiency, to be comparable. DOE calculated the percent difference in blue book prices for each pair of dimming and fixed light output ballasts. The average percent increase from fixed light output ballasts to dimming ballasts was 120
pe rcent. Because DOE determined that programmed start (PS) fi xed light output ballasts were the most similar to the dimming ballasts selected for this analysis, DOE applied a scaling factor of 2.2 to the end-user ballast prices developed for the 2-lamp PS 4-foot MBP, 4-lamp PS 4-foot MB P, 2-lamp PS 4-foot T5 MiniBP SO, and 2-lamp PS 4-foot T5 MiniBP HO systems.
