2.4.4 Effect of switching

operations on

lamp life

Average rated lamp life is based on a switching cycle of 165 minutes on and 15 minu-

tes off in accordance with IEC 60901. If there are fewer switching operations than

under these standard conditions, average rated lamp life will be increased. If, however,

the lamp is switched on and off more than this, it will not last as long.

If an electronic control gear designed for pre heat start is used, the number of possible

switching operations is greatly increased against operation with a CCG thanks to op-

timum warm starting of the lamp.

The typical failure curves below show the basic relationship between the number of

switching cycles and lamp life under rated conditions.

After the lamps have been switched off it is necessary to wait a certain time, depending

on the type of equipment (see ECG specifications), to ensure optimum warm restart

(essential for maximum lamp life).
