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 test a var

different manufacturers. Through an independent testing facility, DOE tested both the ballast efficacy factor (BEF) and bballast. For BEF, DOE used the test procedure outlined in 10 CFR 430, Subpart B, Appendix Q. For BE, DOE used the the fluorescent lamp ballast active mode test procedure notice of proposed rulemaking. Three examples of each ballast ty

average of the three test results is displayed for each ballast type in the tables below. 5C.2 TEST DATA Table 5C.1 Ballasts That Operate Four-Foot MBP and Two-Foot U-Shaped Lamps
