9.1 INTRODUCTION

**The U**  **.S. Department**  **o f**  **Energy (DOE)**  **generated national**  **energy savings**  **(NES) and**  **net**

**present value**  **(NPV) results**  **based on**  **trial standard**  **levels (TSLs).**  **The TSLs**  **designate an** 

**efficacy 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”).**  **Chapter 5**  **of the**  **TSD and** 

**section V.A**  **of the**  **Notice of**  **Proposed Rulemaking**  **(NOPR) discuss**  **product classes**  **in greater** 

**detail. DOE**  **then scaled**  **the standards**  **for the**  **representative product**  **classes to**  **create standards** 

**for other**  **product classes**  **that were**  **not directly**  **analyzed.**

9.2.2 Trial Standard Le vels

**DOE developed**  **TSL s**  **that generally**  **follow a**  **trend of**  **increasing efficacy**  **by using**  **higher**

**quality phosphors.**  **The TSLs**  **also represent**  **a general**  **move from**  **higher wattage**  **technologies to** 

**lower wattage,**  **lower diameter**  **lamps with**  **higher efficacies.**  **DOE analyzes**  **systems that**  **meet**

**each efficacy**  **level in**  **the TSLs**  **by pairing**  **standard and**  **reduced­wattage lamps**  **featuring a** 

**variety of**  **design options**  **with appropriate**  **magnetic or**  **electronic ballasts.**  **As discussed**  **in the** 

**screening analysis**  **(NOPR TSD**  **chapter 4),**  **DOE uses**  **design options**  **with highly**  **emissive**

**electrode coatings,**  **higher efficiency**  **lamp fill**  **gas composition,**  **higher efficiency**  **phosphors,**

**glass coatings,**  **or lamp**  **diameter to**  **achieve higher**  **efficacy levels.**  **The TSLs**  **for the**  **five**

**TSL1, which**  **would set**  **energy conservation**  **standards for**  **GSFL to**  **EL1 for**  **all product** 

**classes, would**  **eliminate the**  **4­foot MBP**  **T12 baselines,**  **the 95W**  **T12 8­foot**  **RDC HO**  **baseline,**

**9­2 and**  **the 75W**  **T12 8­foot**  **single pin**  **slimline baseline**  **from the**  **market. In**  **the 4­foot**  **MBP product** 

**class, this**  **TSL could**  **be met**  **either with**  **a 40W**  **T12 lamp**  **using improved**  **700­series or**  **800­**

**series phosphors,**  **or with**  **a 34W**  **T12 lamp**  **using a**  **700­series phosphor.**  **A 4­foot**  **MBP lamp** 

**using only**  **halophosphors would**  **not be**  **able to**  **meet this**  **TSL. The**  **75W 8­foot**  **SP slimline**  **T12**

**and 110W**  **RDC HO**  **lamps would**  **need to**  **use an**  **800­series rare**  **earth phosphor**  **to meet**  **TSL1.**

**TSL1 also**  **represents a**  **level which**  **would likely**  **prevent the**  **commercialization of**  **T5 lamps** 

**which halophosphor**  **coating while**  **allowing for**  **800­series 4­foot**  **T5 MiniBP**  **and 4­foot**  **T5**

**MiniBP HO**  **lamps that**  **are currently**  **commercially available**  **to remain**  **on the**  **market.**

**TSL2 would**  **se t**  **energy conservation**  **standards for**  **GSFL at**  **EL2 for**  **4­foot MBP,**  **8­foot**

**SP slimline,**  **and 8­foot**  **RDC HO**  **lamps. The**  **34W T12**  **4­foot MBP**  **lamps would**  **likely be** 

**required to**  **use 800­series**  **rare earth**  **phosphors to**  **meet TSL2.**  **For 40W**  **T12 lamps,**  **TSL2 is** 

**expected to**  **require a**  **premium 800­series**  **rare earth**  **phosphor and**  **is the**  **maximum TSL**  **that a** 

**40W T12**  **would be**  **able to**  **meet. In**  **the 8­foot**  **SP slimline**  **product class,**  **TSL2 is**  **expected to** 

**require a**  **premium 800­series**  **rare earth**  **phosphor for**  **the 75W**  **T12 and**  **is the**  **maximum TSL**  **that**

**75W T12**  **would likely**  **be able**  **to meet.**  **This standard**  **level would**  **eliminate the**  **60W T12** 

**baseline and**  **require a**  **700­series phosphor**  **for this**  **lamp. In**  **the 8­foot**  **RDC HO**  **product class,** 

**TSL2 would**  **eliminate 110W**  **T12 lamps**  **and the**  **95W T12**  **baseline and**  **would require**  **rare earth** 

**700­series phosphors**  **for 95W**  **T12 lamps.**  **For T5s,**  **TSL2 still**  **represents the**  **first efficacy**  **level,**

**which would**  **allow for**  **800­series 4­foot**  **T5 MiniBP**  **and 4­foot**  **T5 MiniBP**  **HO lamps**  **to remain** 

**on the**  **market.**

**TSL3 would**  **se t**  **energy conservation**  **standards for**  **GSFL at**  **EL3 for**  **4­foot MBP,**  **8­foot**

**SP slimline,**  **and 8­foot**  **RDC HO**  **lamps. In**  **this product**  **class, the**  **32W T8**  **baseline would**  **be**

**eliminated from**  **the market.**  **To produce**  **a TSL3­compliant**  **32W T8**  **lamp, manufacturers**  **would**

**need to**  **use an**  **800­series rare**  **earth phosphor.**  **The 34W**  **T12 lamps**  **would likely**  **require an** 

**improved 800­series**  **rare earth**  **phosphor mixture**  **and possibly**  **other design**  **options, such**  **as a** 

**different gas**  **fill or**  **increased thickness**  **of the**  **bulb­wall phosphor.**  **Only reduced­wattage**  **(34W)**

**4­foot MBP**  **T12 lamps**  **are expected**  **to meet**  **this TSL.**  **In the**  **8­foot SP**  **slimline product**  **class,**

**TSL3 would**  **require the**  **use of**  **an 800­series**  **60W T12**  **lamp. This**  **standard level**  **is expected**  **to**

**eliminate all**  **75W T12**  **lamps and**  **require an**  **improved 700­series**  **phosphor for**  **the 60W**  **T12. In** 

**the 8­foot**  **RDC HO**  **class, TSL3**  **requires 95W**  **T12 lamps**  **to shift**  **to 800­series**  **rare earth** 

**phosphors. TSL3**  **also represents**  **the first**  **efficacy level**  **for 4­foot**  **T5 MiniBP**  **and 4­foot**  **T5**

**MiniBP HO**  **lamps, retaining**  **800­series versions**  **of those**  **lamps on**  **the market.** 

**TSL4, which**  **wo uld**  **set energy**  **conservation standards**  **for GSFL**  **at EL4**  **for 4­foot**  **MBP,**

**8­foot SP**  **slimline, and**  **8­foot RDC**  **HO, is**  **expected to**  **eliminate 4,100K**  **T12 lamps**  **from the** 

**marketplace. TSL4**  **is also**  **expected to**  **raise the**  **efficacy of**  **all full­wattage**  **T8 lamps**  **above the** 

**baselines for**  **the aforementioned**  **product classes.**  **In the**  **4­foot MBP**  **product class,**  **TSL4 could** 

**be met**  **by improved**  **800­series full­wattage**  **T8 lamps,**  **or by**  **800­series 30W**  **and 25W**  **T8 lamps.** 

**For the**  **8­foot SP**  **slimline product**  **class. 59W**  **T8 lamps**  **would likely**  **need to**  **use an**  **800­series**

**rare earth**  **phosphor to**  **meet TSL4.**  **TSL4, while**  **expected to**  **eliminate 8­foot**  **T12 RDC**  **HO**

**lamps from**  **the market,**  **would require**  **an improved**  **700­series mixture**  **to be**  **used in**  **T8 lamps**  **for**

**this product**  **class. TSL4**  **also represents**  **the first**  **efficacy level**  **for 4­foot**  **T5 MiniBP**  **and 4­foot** 

**T5 MiniBP**  **HO lamps,**  **retaining 800­series**  **T5 lamps**  **on the**  **market.**

**9­3 TSL5**  **represents the**  **max­tech EL**  **for all**  **GSFL product**  **classes. T12**  **lamps and**  **700­**

**series T8**  **lamps are**  **expected to**  **not be**  **able to**  **meet this**  **level. In**  **the 4­foot**  **MBP and**  **8­foot SP** 

**slimline product**  **class, T8**  **lamps would**  **need to**  **have a**  **premium 800­series**  **rare earth**  **phosphor**

**coating to**  **meet TSL5.**  **TSL5 could**  **also be**  **met by**  **the 28W**  **reduced­wattage 4­foot**  **MBP T8** 

**lamp and**  **the 57W**  **and 55W**  **reduced­wattage 8­foot**  **SP slimline**  **T8 lamps.**  **TSL5 would**  **require**

**movement 800­series**  **T8 lamps**  **in the**  **8­foot RDC**  **HO product**  **class. For**  **the 4­foot**  **T5 MiniBP** 

**SO product**  **class, a**  **standard­wattage (28W)**  **and reduced­wattage**  **(26W) T5**  **with an**  **improved**

**800­series phosphor**  **would need**  **to be**  **used in**  **order to**  **meet TSL5.**  **Because DOE**  **created only** 

**one efficacy**  **level for**  **the 4­foot**  **T5 MiniBP**  **HO lamps,**  **TSL5 would**  **set energy**  **conservation**

**standards 4­foot**  **T5 MiniBP**  **HO lamps**  **at EL1**  **and allow**  **800­series T5**  **HO lamps**  **to remain**  **on**

**the market.**
