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？
谢谢！

表面的翻译是可以这么解释，也有L70与L50的说法。

那UL1993中的End-of-lamp-life tests是什么啊？

针对SSL，THE END-OF-LAMP-LIFE指的是灯的寿命测试，但只用测试光衰，以L70、L50标识寿命，不用测试至死灯。

At the end of lamp life the ballast shall behave in such a way that no overheating of lamp cap(s occurs at any voltage between 90% and 110% of the rated supply voltage.

For the test simulating end of lamp life effects, three tests are described:

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.

+ F& \- ?% c4 X0 l 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.
Lamps used in the ballast test circuits shall be new lamps seasoned for 100 h.
