4.4 Operating values of the lamps as a function of mains voltage
Operating position:
Base up, free-operating
Ambient temperature: 25 °C
Typical curves for the electrical an photometric data as a function of mains voltage for OSRAM DULUX® lamps
in reference magnetic ballast operation.
For ECG operation the variation of luminous and electrical parameters with variation of mains
voltage depends strongly on the individual ECG design. There are current controlled, power
controlled and mixed controlled characteristics available, which keep the respective electrical
parameters more or less constant. The photometric parameters of the lamp will follow the
operational parameters of the ECG.
