| Use term |
Compact: 60,000 hrs
separate category: 100,000 hrs |
6,000~20,000hrs The change in physical conditions in electrode hot operation leads to an increasingly serious mismatching with ballast and shortens the use term.. |
24,000 hrs
The reason for short use term is similar with metal halide |
3,000~6,000 hrs
The reason for short use term is similar with metal halide |
