мг70

добрый день! подскажите пожалуйста владельцы Мг по 70вт. на каком расстоянии у вас прожекторы над водой висят. у меня от защитного стекла до воды 20см. Кажется маловато?
и сразу еще вопрос. Эпра у меня osram powertronic pt-fit 70вт. Нигде не могу найти расстояние, на которое можно удалить это самое ЭПРА от лампы. Нигде в описании ничего нет. Если его переместить в тумбу, расстояние будет 4-5м.

2.2.4.3 Cable length between
the ECG and lamp The cable length between the POWERTRONIC ECG and the lamp/lu-
minaire is critical for:
• Reliable starting of the system
• Compliance with the EMC limit values of the lighting installation

Reliable lamp starting must also be ensured even under adverse con-
ditions such as low ambient temperatures, high humidity levels and
aged lamps.
The load capacity of the cable is definitive for the length of the cable. A
standard cable of approximately 80 pF/m can be taken as an orienta-
tion value for the cable capacity. The exact values must be requested
each time from the respective cable manufacturers.
If longer cable lengths are required, it is recommended:
1. to use cables with especially low capacities
2. to select a luminaire structure that has lamp-sided wiring with a low
coupling capacitor to PE.
In general for POWERTRONIC PTi ECG a load capacity of 120 pF ap-
plies which equals a cable length of about 1,5 m. A detailed overview
of the maximum possible load capacity for each ECG can be found in
the technical data in the Appendix.
As well as reliable ignition, the cable length has a major influence on
the EMC behavior of the lighting installation.
Detailed information can be found in the following section on cable
routing.
