Note: Using a warm start designed ECG build upon an older technology, it is possible that after the
lamps have been switched off, it is necessary to wait a certain time, before switching on the lamps
again, to ensure a reliable warm restart of the lamps (see ECG specifications).
In any case, using the modern types of ECG, best available technology (BAT), it is not necessary to
wait a certain time anymore, there is no restriction on switching cycles or switching off time periods
affecting the lamp life, under normal operation conditions.
If an electronic control gear designed for an instant start is used, the number of possible switching
cycles is strongly decreased compared to an operation with warm start ECG. For an operation with
instant start ECG, a maximum of 2 switching cycles per day is recommended, without affecting the
lamp life.
