Relationship between luminous flux and hours burned (maintenance) for CCG operation
Relationship between luminous flux and hours burned (maintenance) for ECG operation
The curves shown here are the result of a large number of investigations under controlled and constant
laboratory conditions. In actual practice, individual lamps or groups of lamps may deviate from these
values.
A 3-hour switching cycle is used (165 minutes on / 15 minutes off).
The initial value for luminous flux corresponds to the 100 h value.
