Any of the three tests may be used to qualify electronic ballasts. The ballast manufacturer shall determine which of the three tests will be used to test a given ballast based on the design of that particular ballast circuit. The chosen test method shall be indicated in the ballast manufacturer’s literature." @, S0 W% f* P8 w. ^

NOTE Checking ballasts against their capability to cope with the partial rectifying effect is recommended by IEC 61195, Annex E, and IEC 61199, Annex H.' d ]; T6 q: c7 O
Lamps used in the ballast test circuits shall be new lamps seasoned for 100 h. |

请问THE END-OF-LAMP-LIFE是灯的寿命测试吗？同光衰测试至死灯应该是一个意思吧？
