Interpretation of Active Mode 

### EPCA Definition of “Active Mode” (42 U.S.C. 6295(gg)(1)(A)(i)) DOE must interpret the definition of “active mode” in the context of fluorescent lamp ballasts to clarify the definitions of “off mode” and “standby mode” which both use the term “active mode.” “[T]he condition in which an energy-using product– (I) is connected to a main power source; (II) has been activated; and (III) provides 1 or more main functions.”

### DOE Interpretation of “Active Mode” For Fluorescent Lamp Ballasts

 A ballast is in “active mode” if it is operating one or more fluorescent lamps.  To account for both dimmable and non-dimmable ballasts, DOE defines active mode as when the lamp-and-ballast system exhibits any non-zero level of light output.  Therefore “active mode” exists when light output is greater than zero percent.

Interpretation of Standby Mode 

### EPCA Definition of “Standby Mode ” (42 U.S.C. 6295( gg)(1)(A)(iii)) “[T]he condition in which an energy-using product– (I) is connected to a main power source; and (II) offers 1 or more of the following user-oriented or protective functions:

(aa) To facilitate the activation or deactivation of other functions (including active mode) by remote switch (including remote control), internal sensor, or timer. (bb) Continuous functions, including information or status displays (including clocks) or sensor-based functions.” DOE is focusing on two aspects of the EPCA definition: • Connection to a main power source • Activation or deactivation of other functions by remote switch or internal sensor 11

12 

### DOE Interpretation of “Standby Mode” for Fluorescent Lamp Ballasts  Most ballasts are turned off via switches that disconnect main power, so they do not enter standby mode.  Standby mode only applies to ballasts with a lighting control interface.



## • At zero light output, the ballast consumes energy while waiting for instruction from the li ghting control system.

Interpretation of Off Mode 

### EPCA Definition of “Off Mode” ( 42 U.S.C. 6295(gg)(1)(A)(ii)) “[T]he condition in which an energy-using product– (I) is connected to a main power source; and (II) is not providing any standby or active mode function.”

EISA directs DOE to address “off mode” in this test procedure. (42 U.S.C. 6295(gg)(2))

### DOE Interpretation of “Off Mode” for Fluorescent Lamp Ballasts

 Off mode does not apply to fluorescent lamp ballasts. 

## • A ballast in a system producing any amount of light output is in Active Mode. 

## • At zero light output, a ballast connected to a main power source while waiting for lighting control instruct ions is considered to be in Standby Mode. 

## • If a ballast is not operating the lamp to produce light and not in standby mode, the ballast must be disconnected from the main power source, which doesn’t meet the criteria of Off Mode.  Thus, DOE proposes not to incorporate a test method for off mode energy consumption.

### Covered Ballasts
 DOE is considering “standby mode” as only applicable to ballasts that incorporate a lighting control interface.  Although DOE does not currently cover many fluorescent lamp ballasts that have a lighting cont rol interface (like T8 ballasts or dimming ballasts), DOE has the authority to cover these ballasts in the ballast energy conservation standards rulemaking initiated on January 22, 2008. (73 FR 3653) Scope of Applicability

Issue 4: DOE invites comment on its interpretation of which ballasts are covered by the standby mode test procedure.

Scope of Applicability 

### Effective Date

 The fluorescent lamp ballast sta ndby and off mode test procedure final rule EISA deadline is March 31, 2009. (42 U.S.C. 6295(gg)(2)(B)(ii))  The final rule will become eff ective 30 days after its publication.  The standby test procedure final rule will not change how manufacturers measure and establish compliance with existing energy conservation standards.  If new standby mode energy conservation standards are adopted, these standards will not be effective until 5 years after the effective date of the previous amended rule but not within 3 years after the publication of the fluorescent ball ast energy conservation standards rulemaking final rule in June 2011. (42 U.S.C. 6295(g)(4)(C))

### Active Mode Test Procedure for Fluorescent Lamp Ballasts

 DOE is planning to initiate a test procedure rulemaking in 2009 to review and possibly amend the active mode efficiency measurement of ballasts.  In the fluorescent lamp ballast active mode test procedure rulemaking, DOE will consider updating the references to industry standards so that they harmonize with the referenced standards in today’s proposed standby mode test procedure.

### Standby Mode Overview for Fluorescent Lamp Ballasts
 Only applies to ballasts that are part of a lighting control system.  In standby mode, the ballast produces zero light output, yet consumes energy while awaiting a control signal.



### Standby Power = Input Power + Control Signal Power Standby Mode Overview

No Lumen Output Mains Ballast Lamp
Lamp No Regulated

Current Input Power No Lumen Output

Control Signal Control Signal Power

22 

### Method for Measurement of Standby Power 1. Send a signal to the ballast instructing it to have zero light output. 2. Measure the input power to the ballast (in watts) in accordance with ANSI Standard C82.2–2002, section 13. 3. Measure the alternating current (AC), direct current (DC), or power line carrier (PLC) control signal using the appropriate method.



## • DOE estimates that control systems us ing wireless signals supply less than 1.0 watts of power to the ballast, so wireless control signal power is not measured.

### Proposed Definition and Standby Mode Measurement for: Alternating Current Control Signal AC control signal : “an alternating current (AC) signal that is supplied to the ballast using additional wiring for the purpose of controlling the ballast and putting the ballast in standby mode.”
 Measure the AC control signal power (watts), using a wattmeter (W), connected to the ballast in accordance with the circuit below.

### Proposed Definition and Standby Mode Measurement for: Direct Current Control Signal DC control signal : “a direct current (DC) signal that is supplied to the ballast using additional wiring for the purpose of controlling the ballast and putting the ballast in standby mode.”
 Measure the DC control signal voltage, using a voltmeter (V), and current, using an ammeter (A), connected to the ballast in accordance with the circuit below.

### Proposed Definition and Standby Mode Measurement for: Power Line Carrier (PLC) Control Signal

 Measure the PLC control signal power (watts), using a wattmeter (W), connected to the ballast in accordance with the circuit below.  The wattmeter must have a frequency response that is at least 10 times higher than the PLC being measured in order to measure the PLC signal correctly. The wattmeter must also be high-pass filtered to filter out power at 60 Hertz.

PLC control signal : “a power line carrier (PLC) signal that is supplied to the ballast using the input ballast wiring for the purpose of controlling the ballast and putting the ballast in standby mode.”

Standby Mode Overview 

### Proposed Definition and Standby Mode Measurement for: Wireless Control Signal Wireless control signal : “a wireless signal that is radiated to and received by the ballast for the purpose of controlling the ballast and putting the ballast in standby mode.”
 Wireless control signal power is not measured because DOE estimates that the power supplied to a ballast using a wireless signal is much less than 1.0 watt.

### New Test Conditions for Measuring Standby Mode Power
 Current fluorescent lamp ballast active mode power test procedure references ANSI C82.2-198 4 for test conditions.  The proposed standby mode power test procedure references ANSI C82.2-2002 (current version) for test conditions.  DOE will consider updating the ANSI references in the active mode power test procedure during a rulemaking scheduled to begin in 2009. New Test Conditions
