## Test Procedure Overview

Issue 1: DOE requests comments on all aspects of DOE’s test procedures for GSFLs, GSILs, and IRLs.13 | Building Technologies Program eere.energy.gov 

## Test Procedure Agenda
2 4 Background and Legal Authority Updates to Industry Standards: GSFL, GSIL, IRL 2 1 Overview 3 New GSIL Lifetime Test Procedure14 | Building Technologies Program eere.energy.gov 

### The following updates to industry standards for the GSFL and GSIL test procedures are proposed. 

## Updates to Industry Standards Incorporated by Reference Currently Referenced

Standard Updated Standard to be Referenced Title ANSI C78.81 2005, ANSI C78.81 - 2003 ANSI C78.81 - 2010 American National Standard for Electric Lamps -Double- Capped Fluorescent Lamps Dimensional and Electrical Characteristics IESNA LM - 9 - 1999 IES LM - 9 - 2009 IES Approved Method for the Electrical and Photometric Measurement of Fluorescent Lamps IESNA LM - 45 2000 IES LM - 45 - 2009 IES Approved Method for the Electrical and Photometric Measurement of General Service Incandescent Filament Lamps15 | Building Technologies Program eere.energy.gov 

### DOE proposes to update all references to ANSI C78.81 (both 2003 and 2005) to ANSI C78.81 -2010. • ANSI C78.81 addresses dimensional and electrical characteristics for double - capped fluorescent lamps. • ANSI C78.81 - 2010 adds high -frequency and low-frequency lamp specifications for 25 -watt (W), 28W, and 30W, reduced -wattage 4 foot T8 medium bipin (MBP) lamps. • The low-frequency reference ballast specifications in ANSI C78.81 2010 for these lamps have no impact because they are identical to the specifications DOE currently directs manufacturers to use for those fluorescent lamps in section 4.1.2.1 of Appendix R. 

## ANSI C78.81 - 2010 for GSFLs16 | Building Technologies Program eere.energy.gov 

### DOE proposes to update IESNA LM -9- 1999 to the more recent version IES LM -9-2009 for fluorescent lamps. 1. Addition of guidance for high -frequency testing: root mean square (RMS) voltage regulation, instrument frequency response, reference ballast impedance, circuit setup. 2. Modifies lamp stabilization method to require more consecutive measurements be taken until stabilization criterion is met. 3. Addition of lamp stabilization guidance unique to T5 linear fluorescent lamps. 4. Adds impedance thresholds for voltage and current inputs to multimeter and power sources. 

## IES LM - 9 - 2009 for GSFLs17 | Building Technologies Program eere.energy.gov 

### DOE proposes to update IESNA LM -45 -2000 to the more recent version IES LM -45 -2009 for incandescent lamps. 1. Modifies lamp stabilization method requiring measurements to continue until stability criteria is met. 2. Modifies voltage and current regulation tolerances for AC power source. 3. Modifies instrument tolerances for AC voltage, current and wattage. 4. Adds impedance thresholds for voltage and current inputs to multimeter. 5. Adds a requirement for the degree of spectral match of the photo detector measurements to the V(λ) function. 

## IES LM - 45 - 2009 for GSILs18 | Building Technologies Program eere.energy.gov 

## Issues for Discussion

Issue 3: DOE requests comments on its proposed incorporation of IES LM - 45 - 2009, and its tentative conclusion that the update would neither significantly affect lamp efficacy values nor impose an undue testing burden. Issue 2: DOE requests comments on its proposed incorporation of IES LM - 9 - 2009, and its tentative conclusion that the update would neither significantly affect measured lamp efficacy nor increase the testing burden. In particular, DOE requests comments on the impact on lamp efficacy of high -frequency testing amendments and modifications to the lamp stabilization procedure in IES LM - 9 - 2009.19 | Building Technologies Program eere.energy.gov 

### Existing IRL test procedure incorporates IESNA LM -20- 1994. 10 CFR part 430, subpart B, Appendix R

• Revised edition of the standard has not been published. • Not aware of any current best practices or technical developments that necessitate modifications to the IRL test procedure. 

## Test Procedures for IRLs

Issue 4: DOE requests comment on whether any amendments to the IRL test procedure are necessary and welcome any suggestions for amendments.20 | Building Technologies Program eere.energy.gov 

## Test Procedure Agenda
2 4 Background and Legal Authority Updates to Industry Standards: GSFL, GSIL, IRL 2 1 Overview 3 New GSIL Lifetime Test Procedure21 | Building Technologies Program eere.energy.gov 

### • EISA 2007 amended EPCA by prescribing GSIL minimum rated lifetime requirements to be phased in between January 2012 and January 2014. • Proposed GSIL Lifetime Test Procedure

**−** Industry standard: IESNA LM - 49 - 2001, “IESNA Approved Method for Life Testing of Incandescent Filament Lamps.” o Coincides with rated voltage testing prescribed in the IESNA Lighting Handbook. o Referenced by Federal Trade Commission in regulations for product labeling.

**−** Definition of “rated lifetime for general service incandescent lamps”: rated lifetime is the length of operating time between first use and failure of 50 percent of the prescribed sample size.

**−** Sample size of 20 lamps. 

## GSIL Lifetime Test Procedure Overview22 | Building Technologies Program eere.energy.gov 

## IESNA LM - 49 - 2001: Summary

• Prescribes lifetime testing at a rated voltage. • Requires lamp to be checked for failure at regular intervals and cooled on a daily basis. • Provides instrument specifications for voltage, current and frequency. • Specifies test conditions for vibration, temperature and airflow. • Addresses lamp orientation, spacing, handling, marking of lamps, and lamp holder specifications.23 | Building Technologies Program eere.energy.gov 

### • DOE proposes to disallow use of accelerated lifetime testing

**−** LM - 49 permits accelerated lifetime testing for non - halogen GSILS; few non - halogen GSILs will meet 2012 energy conservation standards.

**−** Difficult to conduct for halogen lamps due to the tungsten - halogen regenerative cycle which is designed around certain operating temperatures 

### .

**−** Accurate scaling factors will require numerous comparison tests and need to be developed for each lamp design. 

## IESNA LM - 49 - 2001: Accelerated Lifetime Testing

Accelerated Lifetime Testing • Operate lamps at overvoltage, increasing operating temperature and shortening lamp lifetime • Use empirically derived scaling factors to determine full lifetime of lamp24 | Building Technologies Program eere.energy.gov 

### DOE proposes a minimum sample size of 20 lamps. • Minimum of two lamps per month for seven months of production out of a 12 - month period • Consistent with statutory definition of lifetime which requires “statistically large group of lamps.” (42 U.S.C. 6291(30)(P)) • Consistent with required sample size of 21 lamps for measuring lamp efficacy. 

## GSIL Lifetime Testing: Sample Size25 | Building Technologies Program eere.energy.gov 

## Issues for Discussion Issue 5: DOE requests comment on its proposal to adopt IESNA LM - 49 - 2001 as the standard for GSIL lifetime testing. Issue 6: DOE requests comments on its proposal to disallow accelerated lifetime testing as part of the GSIL test procedure. Issue 7: DOE requests comments on its proposal to require a minimum sample size of 20 lamps for GSIL lifetime measurements.26 | Building Technologies Program eere.energy.gov 

## GSIL Certification Requirements

Issue 8: DOE requests comment on its proposal regarding GSIL certification filing requirements. GSIL new model filing requirements are similar to those for GSFLs and IRLs. • Initial certification report describing the methodology by which it was determined the model meets or exceeds standards submitted prior to or concurrent with distribution of new model. • Final certification report based on full sampling provisions to be submitted one year following the start of manufacturing of new model.27 | Building Technologies Program eere.energy.gov 

## Issues for Discussion
Issue 9: DOE seeks comment regarding whether the proposed amendments in today’s NOPR would have a significant economic impact on any small entities. In particular, DOE requests comments on its preliminary analysis of initial setup and labor costs for conducting lifetime testing of GSILs.28 | Building Technologies Program eere.energy.gov In all correspondence, include all of the following:
