Operating instructions
The lamps must be connected via suitable control
gear. A 240 V / 50 Hz ac supply is generally required.
If a different supply voltage is used (e.g. 400 V / 50 Hz)
control gear with appropriate taps must be used.
Permitted mains voltage deviation: ± 3%
Sudden fluctuations in mains voltage of more than
10% may cause the lamps to go out.
If the deviation from rated supply voltage (230 V or
400 V) is permanent, high-pressure discharge lamps
may exhibit changes in colour or luminous flux. Lamp
life may also be reduced.
Conventional control gear: Choke, igniter and pf
correction capacitor.
The right igniter for the particular lamp type must be
used to ensure reliable and safe ignition.
Igniters must always be installed close to the lamp.
The choke may be installed any distance from the
lamp, provided the permissible voltage drop is not
exceeded.
For power supplies with a neutral conductor the choke
should be connected to the live conductor. In the case
of luminaires in which there are no lamps installed,
the ignition equipment (igniter, ignition pulser) must
be disabled when voltage is applied otherwise the
igniters may produce radio interference.
The chokes and pf correction capacitors generally
needed for operating discharge lamps may, under
certain conditions, create oscillating circuits. These
circuits may then produce excessive currents and
voltages, which in turn can destroy the lamps, ballasts
and capacitors. Such resonance phenomena must be
avoided by appropriate circuits and fuses.
When high-pressure discharge lamps come to the
end of their lives a rectifier effect may occur (see IEC
62035). This is not manufacturer-specific. Because
of the excessive dc current components the ballasts
and igniters may become overheated.
High-pressure discharge lamps should therefore only
be operated with control gear with thermal protection.
This applies also to control gear with the option of
power reduction.

Only high-pressure discharge lamps with external
igniters are suitable for low-temperature applications
down to – 50 °C. Such applications call for special
(heatable) igniters such as MZN 400 SU-LT from BAG
Turgi (for lamps from 100 to 400 W).
CCG: Because of the series connected choke this is
around 0.5 to 0.7 (without compensation)
ECG: If POWERTRONIC
greater than 0.96. Compensation is therefore not
needed here.
Full luminous flux is reached only a few minutes after
the lamp is switched on. The start-up current may be
up to twice the operating current depending on the
control gear. (See also the graphs on p. 25)
HCI
If fuse wire is used it is sufficient for it to be rated at
twice the rated current of the lamp. If automatic
cutouts are used they should have characteristic “C”.
If adjusted to the upper limit value of 10 x rated current
there will be no triggering if fuse protection is at twice
the rated lamp current.
The lamps will restart only after they have cooled
down for 2 to 15 minutes.
Because of the high voltages involved in ignition the
lampholders must be designed for these high volt-
ages. Lampholders that meet these requirements are
available from appropriate manufacturers.
In principle, dimming of HCI
cally feasible, but OSRAM does not recommend it
for the lamps currently available on the market, be-
cause the typical characteristics of HCI
BALL
The higher thermal load capacity of the round ceram-
ic burner offers better dimming behavior in terms of
luminous efficacy and color rendering compared to
metal halide lamps with quartz burners or standard
cylindrical ceramic burners.
As before, however, dimming does lead to a change
in the chromaticity coordinates. Lamps operated at
dimmed settings suffer a greater loss of luminous flux
and a greater color shift over their lifetime.
