Fuses
Fuses for all discharge lamps must be proportioned for short time current peaks and the increased run-up current (up to 2 times the
nominal current). We recommend using time lag fuses and automatic devices.
See special instructions for the fuses of metal halide lamps.
Power Factor
no compensation required.
When operated with a ballast the capacity cos
ϕ
of HRI-, HRL- and RNP lamps is about
0,5 . . . 0,7.
When operated with a leakage transformer SOX-lamps obtain a power factor of about 0,3.
For information on capacitors please see tables.
Luminous Flux
The values of the luminous flux always refer to the quoted burning position and the nominal wattage of the lamps. They are defermined
after 100 burning hours with reference gear at laboratory conditions.They are practically independent from the ambient temperature.
Planning note: decline in luminous flux, cf. separateTechnical Information.
When real burning position does not comply with that stated, dramatic changes are to be expected especially in luminous flux, colour
temperature and service life.Technical data for RCC/HRI lamps 250-1000W can only be achieved when operated with RNP ballast.
(Exceptions: HRI-E N/Si, HRI-T N/SI und HRI-T 400W blue).
Radio Interference
Radio interference normally does not occur except for switching the lamp on. In some cases there have been sporadic
interferences withy HRL and MRL lamps used in overhead line systems.This can be avoided by means of a capacitor in parallel connec-
tion of 0,1
µ
F/1000V to the lamp. Please, never use capacitors for HRI-lamps which need an impulse of high frequency voltage!
Installation
Lamp and ballast may be installed in arbitrary distance, whereas the distance between lamp and ignitor must not be more
than approx. 1,5m.
Please switch off a luminary/ flood light without lamp in order to avoid overload by continuous operation of the ignitor.
If the centre lead is not used in three-phase installations and only the common leads are fused, resonance/ resonant circuits may occur.
This way lamps and operation gear may be damaged or even destroyed.
One-based lamps with big outer bulbs (HRI
≥
1000W, RNP-T 1000W and SOX) need some support/ stress-strain relief at the opposite
end from the base.
For employed/ planned luminaries/ flood lights EN 60598-1 (thermal properties and electric fusing) is to be observed.
Guarantee will not be applicable when lamps are operated in improper armatures and in not permitted conditions.
Safety at Operation
Because of the emitted UV-radiation and of the high operating pressure as a principle all HRI and RCC are to be used in suitable fully closed
luminaries/flood lights, if admission for operating in open fixtures is not specifically stated for this lamp. As a breakage of the lamp bulb cannot
be excluded, luminaries must be fitted with a temperature-change resistant and fracture safe front screen. Operation of lamps with damaged
outer bulb is dangerous and not approved.
At the end of lamps’ service life there may occur rectifier effects, which may lead to overheating of the ballast by direct current.There-
fore, thermal protection is to be provided for acc. to IEC 62035.
Circuits which can cause resonance effects are to be avoided as a rule.
Please change lamps promptly at the end of their service life which show one of the following properties: change of colour, loss
of light, no ignition, periodic ignition and extinction.
Operation off Nominal Conditions
Short switching cycles (< 3h on, ½ h off) shorten the lamp’s life. Therefore, operation on demand such as with a motion detector is not
sensible.
At low temperatures < –20°C (down to –50°C) lamps start for sure only with external, especially suited, heated igniters.
Reduction of power (additional impendance) of 50% is possible for HRL and RNP when starting with nominal conditions. This is not ap-
plicable for HRI and RCC, because there can occur changes of colour and/ or shortening of life time.
