Fluorescent Lamp Ballasts 

Test Procedure Notice of 

Proposed Rulemaking Public 

Meeting 

The Department of Energy (DOE) is holding a 

public meeting that will first cover the test 

procedure notice of proposed rulemaking 

(NOPR) for fluorescent lamp ballasts and then 

the energy conservation standards rulemaking 

for the same products. This public meeting 

gives DOE an opportunity to present the 

proposals in the test procedure NOPR and to 

respond to stakeholder questions. DOE will 

also seek input from interested parties on the 

planned methodologies, assumptions, data 

sources, and the NEMA Alternative Test 

Procedure Handout.

This document outlines a draft NEMA 

test procedure for the measurement 

of fluorescent lamp ballast efficiency. 

DOE summarizes this test procedure 

as an alternative method under 

consideration in the fluorescent lamp 

ballast active mode test procedure 

NOPR in section III.E.2. DOE requests 

comment on this alternative test 

method as noted in section V.E.5 of 

the test procedure NOPR.

APPENDIX 5C. FLUORESCENT LAMP BALLAST TEST DATA 

5C.1 INTRODUCTION  The following appendix lists the test data DOE used to develop the engineering analysis. DOE chose to teballasts from many different manufacturers. Through an independent testing facility, DOE tested both the ballast and ballast efficiency (BE) of the ballast. For BEF, DOE used the test procedure outlined in 10 CFR 430, SubparBE, DOE used the test procedure proposed in the fluorescent lamp ballast active mode test procedure notice of p

Three examples of each ballast type were tested, and the average of the three test results is displayed for each balbelow. 5C.2 TEST DATA Table 5C.1 Ballasts That Operate Four-Foot MBP and Two-Foot U-Shaped Lamps
