9.1 INTRODUCTION
The U.S. Department of Energy (DOE) generated national energy savings ( NES ) and net present value ( NPV ) results based on trial standard levels (TSLs). The TSLs designate an effic iency level (EL) for each product class. ELs are developed for each product class in the engineering analysis. In this chapter, DOE is only presenting the TSLs of the product classes that DOE analyzed directly (the “representative product classes”).

9.2 REPRESENTATIVE PRODU CT CLASSES
In chapter 3 of the technical support document ( TSD ) , DOE i dentifies five product classes for fluorescent lamp ballasts. Rather than analyze all product classes, DOE selected certain product classes as “representative” to analyze in further detail. Representative product classes include: (1) instant start (IS) and rapid start (RS) ballasts that operate 4 -foot medium bipin (MBP) and 8- foot slimline lamps; (2) programmed start (PS) ballasts that operate 4 -foot MBP, 4 -foot T5 miniature bipin (MiniBP) standard output (SO), and 4-foot T5 MiniBP high output (HO) lamps ; ( 3) IS and RS ballasts that operate 8- foot HO lamps ; and (4) sign ballasts. Details on how these product classes were selected can be found in chapter 5 of the TSD. Table
9.1 shows all of the product classes and designates those which were considered to be representative.

DOE analyzed the benefits and burdens of a number of TSLs for the ballasts that are the subject of today’s proposed rule. Table 9.2 presents the trial standard levels and the corresponding product class efficiency levels. Se e the engineering analysis in chapter 5 of the
TSD for a more detailed discussion of the efficiency levels.

TSL 1 , which would set energy conservation standards at EL1 for all product classes, would eliminate currently available 2

- lamp MBP T12 RS (commercia l and residential), lowefficiency 2

- lamp 4-foot MBP T8 PS, magnetic 8 -foot HO, and magnetic sign ballasts. TSL 1 would require IS and RS 2- lamp MBP ballasts that operate T8 lamps. TSL 1 does not impact 8- foot slimline or 4

- lamp MBP IS and RS ballasts

. TSL 1 also prevents the baseline inefficient T5 standard and high output ballasts from becoming prevalent in future years. Because s ig n ballasts have only one EL, TSL 1 represents the max tech level for the sign ballast representative product class. TSL 2 and TSL 3 also require EL1 for sign ballasts.

TSL 2 would set energy conservat ion standards at EL2 for the IS and RS, PS, and 8-foot
HO IS and RS product classes. This level would eliminate standard

. TSL 2 eliminates the least efficien t T12 2- lamp slimline ballasts, and is just met by the least efficient T8 8-foot slimline ballasts. TSL 2 does not affect 4- lamp MBP T8 IS ballasts. For PS ballasts, h igh

efficiency 4-foot MBP and high

- efficiency T5 standard and high output ballasts are required at TSL 2. This TSL would eliminate the least efficient currently available standard and high output T5 ballasts. TSL 2 for the 8 -foot HO IS and RS product class results in the elimination of current T12 electronic ballasts, but can be met with T8 el ectronic ballasts.

TSL 3 would set energy conservat ion standards at EL3 for the IS and RS, PS, and 8-foot HO IS and RS product class. TSL 3 represents the highest EL analyzed in all representative9-3 product classes and is t he max tech TSL. Ballasts that meet TSL 3 represent the most efficient models tested by DOE in their respective representative product classes.
