OSRAM QUICKTRONIC-M ECG for circular FL 16 mm - Manual (Page 63)

In summary, we can say that the ECG should be installed in such a way
that spray, water drops and condensation cannot enter the ECG and that
moisture and condenses inside the ECG can run out.
An ECG can withstand condensation for short periods but long-term
exposure to moisture should be avoided. The ECG must be operated for at
least 30 minutes per day so that condensation inside the ECG can
evaporate.
The luminaire casing should not be hermetically sealed. Instead, it should
be ventilated so that the condensate that forms during the cool-down period
as a result of the change in temperature (a luminaire is switched on, say, at
–10 °C, warms up during operation to +30 °C and then cools down again to
–10 °C after it has been switched off) is not trapped inside the unit and can
evaporate safely.

6.2 T5-ECG in Sound
Studios
If electronic control gear for T5/ ∅ 16 mm-fluorescent lamps are to be used
in areas in which noise and electromagnetic interference (see also Section
2.7) are important factors there are special requirements that have to be
met when installing the ECG and the luminaires.
6.2.1 Noise and how to
avoid it
Generally speaking, noise is generated in electronic circuits as a „hum“ (at
50 Hz or 100 Hz) or as higher frequency interference in inductances
(chokes, transformers) and capacitors.
Compared with conventional control gear (chokes), electronic controlgear
with their high-frequency mode of operation (in which inductance values are
much lower) generate appreciably lower noise levels and are a problem
only in highly sensitive environments such as sound studios for CD quality
recordings. The fully electronic control gear for T5/
∅ 16 mm-fluorescent
lamps offered by OSRAM is much quieter than conventional ballasts.
T5/
∅ 16 mm-fluorescent lamps can only be operated by electronic
