2. General information on Philips CosmoWhite systems
2.1 Introduction
CosmoWhite has optimum performance for white light in outdoor
applications. Compared to the existing white light sources in outdoor
lighting (Mercury Vapor and Metal Halide) the CosmoWhite system
has superior performance in system efficiency (higher lamp efficacy +
ballast efficiency + better optical efficiency). Moreover, the lumen
maintenance is improved compared to existing ceramic or quartz
metal halide lamps used in outdoor applications. The lamp is very
compact: dimensions are optimized with respect to the optical
performance of the lamp in the luminaire.
Figure 1: Philips CosmoWhite 60W
2.2 Lamp technology
The arc tube technology of the CosmoWhite lamp is similar to the
technology used for Philips CDM-ceramic metal halide lamps:
• PCA (Poly Crystalline Alumina) discharge tube technology
• Rare earth metal iodide technology as used in all metal halide lamps
The CosmoWhite arc tube differs mainly from the CDM-arc tubes by its
geometry that is much longer and thinner. This geometry is optimized
to obtain the best optical performance in typical road and street
lighting optics.
The outer bulb of the CosmoPolis lamps is made from UV-block quartz,
with an outer diameter of 19mm (.75"). The lamp length and light center
length are dependent on the lamp power as shown in section 3.3.
The PGZ12 lamp base and holder are designed for CosmoPolis lamps.
More details about the base and holder are given in section 3.6.
The lamp construction is shown to the left. See Figures 1 and 2.

2.4 Philips CosmoWhite system operation
2.4.1 Starting characteristics
A resonant ignition voltage of 2-2.5 kVp is used by the CosmoWhite
ballast to ignite the CosmoWhite lamp. Pulses are applied to the lamp
with a certain on/off sequence (burst mode) with a total duration of
20 minutes maximum to allow warm restart of the lamp, and at the
same time prevent cycling of an end of life lamp.
As for all discharge lamps, the resistance of the gas in the discharge
tube is related to the gas pressure of the different elements in the
tube. Immediately after ignition the lamp voltage is lower and the
current is higher. After 1.5 to 2 minutes the gas pressure has been
built up and nominal lamp performance is reached. This is shown
in the run-up curves, see Figure 4.
CosmoWhite lamps do not re-ignite instantly. Hot re-strike time is
specified to be less than 15 minutes.
2.4.2 Dependable service of Philips CosmoWhite lamps
CosmoWhite™ lamps have a long rated average life1 of 18,0002 hours
(60W lamp) and 13,0002 hours (140W lamp). Additionally, at 12,000
burning hours (60W lamp) and 9,500 burning hours (140W lamp)
there is only a 10% lamp failure rate with a lumen maintenance of
more than 80%.
Note:
Values listed are for horizontal operation of CosmoWhite lamps. CosmoWhite lamps are
"universal burning", which means that they can be operated in both horizontal and vertical
applications. However, the light technical properties are slightly different in vertical burning
position compared to the horizontal position.
1) Rated average life is the life obtained, on the average, from large representative groups
of lamps in laboratory tests under controlled conditions at 10 or more operating hours per
start. It is based on survival of at least 50% of the lamps and allows for individual lamps or
groups of lamps to vary considerably from the average.
2) If operated vertically, 60w lamp has a 12,500 hour rated average life and 140W lamp has
a 12,000 hour rated average life.
6 OEM Design Guide Philips CosmoPolis
2.4.3 End-of-life behavior of Philips CosmoWhite systems
2.4.3.1 End of life causes
A CosmoWhite lamp can stop functioning after its Rated Average Life
as a result of causes which are similar to a CDM-lamp:
• Due to chemical reactions between the arc tube filling and the PCA
of the tube, the tube will become leaky. The hot gases will flow
through this leak into the outer bulb, noticeable as a weak
discharge in the outer bulb. In principle, it cannot be excluded that
the PCA will break and hot PCA parts may cause a rupture of the
outer bulb (“non-passive failure”)
• If the arc tube becomes leaky, the lamp stops functioning. However,
in some cases the lamp continues burning for a few hundred hours
with a strongly deviating color before it eventually stops completely.
When a lamp operates with strongly deviating color, this might be an
indication of the arc tube being leaky
• At near the lamp end of life, the lamp voltage can rise higher than
can be sustained by the ballast.This voltage rise can be caused by a
change in the chemical composition in the arc tube or by electrodes
wearing out.Thus, in case of a lamp voltage which is higher than can
be sustained, the lamp extinguishes
An overload situation, e.g. a 60W lamp operating on a 140W ballast,
will speed up the occurrence of the above-mentioned failure
mechanisms.
2.4.3.2 System behavior at lamp end-of-life
When the arc tube becomes leaky and the fill gas flows into the outer
bulb, a glow discharge will appear around the metal parts in the outer
bulb. In the arc tube itself no discharge is present anymore.
The glow discharge is not detrimental for any part of the system.
Additionally, the glow effects are limited in time by the electronic
ballast, which switches off the circuit after 20 minutes in case of a
leaky lamp.
When the lamp voltage reaches a high value, the ballast will switch off
the system.This way, disturbing cycling effects (lamps switching on and
off continuously) are prevented.

2.4.4 Influence of mains voltage
Contrary to lamps operating on conventional magnetic ballast, an
electronic ballast provides an almost constant power output (+/- 2%)
within the specified mains voltage performance range (188-305V).
This is favorable for lamp life and energy consumption (no overpower
situation possible). In Figure 5, the lamp power as a function of mains
voltage is shown.
In case of mains voltage below this specified performance range of the
ballast (see ballast specification), the ballast operates the lamp on a
lower power. When the mains voltage drops below ~160V, the ballast
shuts down.

3.1 Introduction
The CosmoWhite system is designed to offer optimal light distribution,
energy savings and miniaturization. To facilitate designing luminaires for
CosmoWhite systems, the critical points of the lamp and ballast are
given in this chapter, together with hints on how to prevent problems.
3.2 General recommendations for fixture design
The general recommendations for luminaire design by Underwriters
Laboratories and the nationally recognized testing laboratories (CSA,
ETL, FM, etc.) are also applicable to CosmoPolis systems. Lamp related
data can be found in IEC 61167 and ANSI C78. The luminaire
manufacturer is advised to conform to the standards of luminaire
design (i.e. UL 1598-Luminaires).

3.4.1 Lamp temperature
3.4.1.1 Set-up for lamp temperature measurements
All lamps and measurement connections must be electrically
insulated to withstand maximum ignition pulses of 5 kV.
The lamps have to be operated on the appropriate Advance ballast
(see chapter 2).
No sleeves have to be used around the lamps for the measurements.
8 OEM Design Guide Philips CosmoPolis
3.4.1.2 Choice and fixation of thermocouples
For the measurements as referred to in this document, NiCr
thermocouples are used.
The fixation of the thermocouples on the lamp is done by engraving a
small depression in the outer bulb. The junction point of the
thermocouple is located in this depression.
For a better fixation of the thermocouple, the two wires are twisted
at the opposite side of the lamp and are fixed at the sides with a high
temperature cement.
The critical temperatures of the lamp must be measured on a burning
lamp1. The critical points and the corresponding temperatures for the
different lamp types are given in the next sections.
3.4.1.3 Critical temperature points and values
The temperatures of the bulb and the pinch are most critical: The
temperature of the bulb is important for the operating temperatures
inside the lamp (arc tube temperature). If this temperature is too high,
the lamp properties and especially the lifetime properties can be
altered. The critical point is just above the light center, at the upper
side of the lamp, when the lamp burns horizontally.
The temperature of the pinch has to be limited to prevent the
oxidation of the molybdenum foils in the pinch of the lamp. Where
the electrodes leave the outer bulb, the molybdenum foil is in contact
with the air. If the temperature exceeds the specification, oxidation
might be accelerated and life might be shortened.
Figure 8: Thermocouple connected to bulb and pinch
To measure the temperature of the pinch, the thermocouple should
ideally be fixed on the pinch at the spot where the joint is between
the outer lead and the molybdenum foil. This temperature is most
critical in the base-up burning position. However, since this point is
not accessible when the lamp base is mounted on the lamp, related
temperatures are given just below the lamp base (See Figure 8 and
Table 5). Lamps should be stabilized for at least ten minutes prior
to the measurement.

1) In previous versions of Philips OEM guides, the cool-down method was advised for
measurement of the lamp temperatures. The argument for the use of this method
compared to measurement on burning lamps, was the fact that the influence of heating
of the thermocouple by direct radiation by the lamp would be excluded. However, with the
current thermocouples the amount of radiation captured by the small thermocouple
junction surface is so small that it can be neglected.
OEM Design Guide Philips Cosmo 9
3.4.2 Electronic ballast temperatures
The temperature of the electronics is the most important parameter
for lifetime and reliability of the ballast. In the ballast design everything
possible is done to keep the component temperatures as low as
possible but the design of the luminaire and the ability to transfer the
heat out of the luminaire is of utmost importance.
Definitions
Ballast temperature: Temperature measured on the Tc point of the ballast.
Ballast ambient temperature: Temperature inside the luminaire around
the ballast.
Luminaire ambient temperature: Temperature outside the luminaire.

Temperature
To enable temperature measurement in a luminaire without measuring
the individual components in the electronic ballast, a Tc point has been
defined (see Figure 10). This point, or the indication where this point
is located can be found on the label of the electronic ballast.The
specified temperature of this point is related to critical temperatures
of components and solder joints inside the electronic ballast.
How this point is related to the component temperatures is
schematically shown in Figure 11.
The Tc point specification of the CosmoWhite ballast has a lower
temperature value than the Tc point spec of some other electronic
ballast in this power range. This is related to the fact that the
CosmoWhite ballast has less power losses and that the Tc point is
at a different location with respect to critical components.These two
facts together ensure a longer lifetime.
Figure 11
In the definition of the Tc point a homogeneous temperature around
the ballast is assumed. In luminaires, especially compact versions, the
temperature around the ballast is not always homogeneous due to
the heat from the lamp. If the temperature around the ballast is not
homogeneous it is advised to also measure the points, indicated in
Figure 12.
Any point in the yellow part of the ballast: < Tc (for required lifetime).
Any point in the red part of the ballast < Tc -5°C (for required lifetime).
The temperatures stated above are only valid for a situation where the
ballast is cooled via the bottom surface. If additional cooling measures
are used please contact your Advance representative. You
will need a ballast with internal attached thermocouples on critical
spots in the ballast to determine if the ballast operates thermally
within specifications.
Figure 12
10 OEM Design Guide Philips CosmoPolis
Example:
If in the application the Tc point measures 80ºC (at which the lifetime
spec of 60,000 hours with 95% survival rate (of the ballast still
operating) is reached for CosmoWhite 60W and 140W ballast) any
point in the yellow part must be 80ºC or lower and any point in the
red part must be 75ºC or lower to achieve the specified lifetime.
Tc temperature and value on the ballast label
In the CosmoWhite product range the Tc point temperature printed
on the ballast label is the maximum temperature the ballast is allowed
to reach.
The Tc point temperature at which the nominal lifetime of 60,000
hours with 95% survival rate (of the ballast still operating) is reached
is 10ºC below the temperature marked on the ballast.
The lifetime at the maximum temperature will be approximately half
the nominal lifetime, at the same failure rate.
This principle also works the other way around. If the Tc point
temperature of the ballast is lower than the temperature at which the
nominal lifetime is reached, the lifetime of the ballast will increase.
However, the number of failed ballasts after a period of e.g. 90,000
hours—compared to the number of failures after 60,000 hours at the
same Tc point temperature—will have increased. The reason for this
is the failure rate will only marginally decrease if temperature goes
down. The failure rate is 0.08% per 1000 hours at Tc = 80°C.
Example:
If a CosmoWhite ballast is operating in the application at Tc = 80ºC/176°F
the lifetime will be 60,000 hours with 95% survivors after 60,000 hours
(0.08%/1000 hours=5% after 60,000 hours). If the ballast is operated at
a temperature below the Tc = 80ºC/176°F the lifetime will be longer.
Advice to obtain maximum lifetime possible:
• Ensure good thermal contact between ballast and “coolest”
spot of luminaire
• The CosmoWhite ballast has heat producing components both in
the upper and lower part of the ballast. Therefore cooling via the
bottom may not give the optimal result. For optimal result it is
advised to also cool the sides of the ballast, including the upper
part of the sides. Be aware that for proper verification of ballast
temperature in this case a ballast with thermocouples supplied by
Advance is needed
• Shield the ballast from the heat of the lamp and reflector.The best
is a two chamber solution, or special measures to transfer heat via
air flow away from the ballast
NOTE: The Tc temperature limits mentioned here and on
the ballast label take precedence over maximum AMBIENT
temperature values mentioned on the ballast label!
Ignition is possible at temperatures as low as -20ºC/-4°F. At very low
temperatures it can take a bit more time to ignite the lamp.

3.5 Influence of ambient temperature on the lamp
In general, HID-lamps are not sensitive to ambient temperatures
as, for example, fluorescent lamps can be, where the ambient
temperature influences the cold spot temperature and, by that, the
free availability of the mercury in the lamp.

3.6 Lamp base and lamp holder
CosmoPolis features a PGZ12 lamp base and holder. A list of the
lamp holder suppliers is given in the Appendix of this guide.This
lamp holder combination is designed for the CosmoPolis system
with the following properties:
• The cap (base) is polarized, which means it has pins with different
diameters (Figure 13), such that it can only be inserted in the lamp
holder in one unique way. This implies that:
- The ignition pulse is always applied on the short pole of the
lamp.The symbol on the lamp holder and ballast is indicated
so that the wires can be connected properly
- The lamps are always mounted in the same position in the
optics (i.e. with the long frame wire at the bottom if burning
horizontally).The holder is equipped with a special feature
to define its orientation in the luminaire (marked with arrow
in Figure 14)
- Good electrical interface between lamp cap (base) and lamp
holder needs to be according IEC60838-1 (miscellaneous
lamps holders—Part 1 general requirements and tests,
Section 15: Endurance), realized by proper material choices
- The PGZ12 is a “pre-focused” lamp base, which means that the
arc tube is aligned with the reference plane of the cap before
fixing the bulb in the cap. Additionally, the specific fit of the
cap in the holder (reference plane of cap is pulled against
upper rim of holder) guarantees minimal tolerance of the
position of the lamp with respect to the reflector. Both of
these elements allow a better positioning of the arc tube
in the reflector and hence lead to a more reliable and
reproducible light output/distribution compared to other
lamp base/holder types such as Edison or G12 caps.This
ensures an optimized optical efficiency in road/street lighting
- The twist and lock concept guarantees an optimal mounting
of the lamp in the luminaire, also integrity in high vibration
applications
See Appendix for a list of lampholder suppliers.
Note 1: All CosmoPolis lamps use the same PGZ12 lamp cap and
holder, without any key to prevent a misconnection. A misconnection
of lamp and ballast (for example a CosmoWhite 60W lamp on a
CosmoWhite 140W ballast) can cause lamp or, very rarely, ballast
failure. In Table 6 below, the effects that occur in all possible
combinations of the different CosmoPolis lamps and ballasts are listed.
No safety issues are encountered in any of these situations.
Note 2: Lamp should be held by the quartz bulb, not by the metal
lamp base, while inserting the lamp.
3.7 Guidelines to comply with norms
3.7.1 Lamp handling—
Fingerprints on metal halide lamps in a quartz outer bulb
(including Philips CosmoPolis lamps).
When low wattage quartz metal halide lamps were introduced it was
stated that the lamp should be cleaned with alcohol if it was touched
by bare fingers. This was based on the same theory as that of halogen
lamps, where the quartz wall temperature is much higher during the
burning of the lamps: the grease and acids of the fingerprints are
burning into the quartz at these temperatures. This has an influence
on the light distribution of the lamp and can result in a possible short
life as the quartz is weakened.
However, the maximum temperature of the outer-bulb of ceramic metal
halide lamps in quartz bulb is much lower (e.g. max < 550ºC/1022°F
for a 140W CosmoWhite lamp). Life tests confirm that after a few
hundred hours all fingerprints are gone. For this reason, the phrase in
the instructions for use (‘wipe-off the lamp with alcohol in case of
fingerprints’) was removed from the instructions for use for CDM
and CosmoPolis lamps.
Information regarding lamp installation instructions can be found
on page 21 and 22.
3.7.2 UV-related data
The CosmoPolis lamps are equipped with a UV-block quartz outer
bulb, thus drastically reducing the UV-output of the lamps. It must be
clear that UV-block lamps have a reduced UV-output and that the UV
is not completely eliminated.
The UV-block of the outer bulb is not done by a special filter or layer
on the quartz but by adding a dope of some metals in the component
mix that is used for the manufacturing of the quartz in the furnace.
The amount of UV that is emitted by the CosmoPolis lamps, can be
expressed using two related quantities, i.e.
• The Permissible Exposure Time (PET), that indicates the maximal
time a human being can be exposed to the light source without risk
for harming skin or eyes. From the spectral power distribution of
the light source and an assumed luminance level of 1000 lux, the
PET value can be calculated
• For the CosmoPolis lamps, the PET values are far above 24 hrs/klux
(actually ~ 1000 hrs/klux) and therefore no restrictions on the
front glass are required with respect to UV-filtering
• The damage factor, that gives an indication for the risk of fading of
the illuminated goods by the emitted UV-light.The damage factor
for all CosmoPolis lamps is smaller than 0.3
All UV-data are summarized in Table 7. Complete UV-spectra can be
obtained on request.

3.7.3 Electromagnetic Interference (EMI)
Advance CosmoWhite
The CosmoWhite ballast operates the lamp on a low frequency
square wave. Guidelines to optimize EMI performance when the
ballast is in the luminaire are stated below.
To achieve the lowest possible level of interference, the following
points should be considered:
1. Keep the mains input wiring (line and neutral) to the ballast
close together
2. Route the mains input wiring immediately away from the ballast.
Preferably, do not route the wiring along or on top of the ballast
3. Keep the lamp wires close together and as short as possible
4. Do not put the lamp wires close to the mains input wiring
This is schematically shown in Figure 15.
LAMP
MAINS
BALLAST
Figure 15: Ballast wiring in luminaire
For optimal EMI behavior the large metal parts of the luminaire
(eg. bottom plate etc) must always be connected to the earth ground
contact of the ballast. Connection of the earth ground terminal to the
metal parts of the luminaire should be kept as short as possible.
Remote ballasting (pole mounting) with CosmoWhite ballast
The CosmoWhite ballast is suitable for pole mounting. It has a
specified cable/wire capacitance of 1000pF, which in practice is up to
10m of cable (with low capacitance cable types this could be more).
The size of the ballast is suitable for mounting in many poles.
In case of pole mounting the gear should always be mounted with the
connectors in the downward direction, to prevent moisture from
entering the connector block.
14 OEM Design Guide Philips CosmoPolis
3.7.4 Lightning strike and transient protection
The CosmoWhite ballast is provided with a transient protection
circuit at its mains input. The protection is capable of absorbing at
least ten times a common mode surge of 10kV/5kA (a so called bi-wave
surge as described in IEEE 62.41.2 between [L&N]-G and lamp holder
NOT connected to GND). This protection gives a substantial
improvement in the survival rate after a lightning strike or other
transient voltage. Absorption of the transient current will limit the
surge voltage in amplitude and duration and is therefore very essential
for the robustness of the product.
To make sure that the lightning strike protection works as intended,
the following guidelines for the luminaire have to be followed:
• The distance from the lamp contacts to any metal part connected to
the earth terminal of the ballast must be >8mm (.31"), and preferably
>10mm (.40")
• The lamp wires must have the classification ‘double insulated’ or
‘reinforced insulation’
During the surge of a lightning strike the mains input including the
ballast, lamp wiring and lamp will rise to a level in the range between
6kV to 8kV, before the protection will bypass the surge current to
ground. During this high voltage surge nothing else may breakdown, to
prevent permanent damage to the system.Therefore the distance of
8mm (.31") minimum is required.
The protection circuit will bypass the surge current to the ground
connector terminal on the ballast. It is important that this current can
flow as direct as possible back to earth ground. For that reason, the
ground contact of the ballast must be connected to large metal parts
of the luminaire and if possible also to the metal pole.
Please note that large metal parts of the luminaire, like the bottom
plate, must always be connected to the ground contact of the ballast.
This is needed for minimal EMI and optimal lightning strike protection.
Information which should be provided to the installer: In case a
grounding wire/cable with a metal arm is used the lightning protection
can be improved by connecting this arm to the metal pole.
In Figures 16 to 24, luminaires with metal, wooden and concrete poles
are shown and it is indicated how the wiring should be done in those
different cases.

3.8 Grounded and double insulated luminaires
The CosmoPolis ballast is suitable for use in both grounded and
double insulated luminaires. How the ballast must be used in the
different situations is explained in the next two paragraphs. In a
grounded luminaire a ground connection cable is present, and touchable
non-insulated metal parts are allowed, since their safety is ensured by
the ground cable connection. In a double insulated luminaire ground
cable connection may not be present. Here metal parts that can be
touched have to be safe without the help of a ground cable connection.
Figure 25
3.8.1 Grounded fixtures
In grounded fixtures the metal in the luminaire is connected to
ground via a ground wire.The ground connection of the ballast must
be connected to the ground in the luminaire for EMI and also
lightning strike protection (see previous chapter). In case there are no
metal parts at all present in the luminaire, the mains ground is directly
connected to the ground connection of the ballast.
3.8.2 Double insulated
In double insulated fixtures there is no ground cable connection
to the luminaire.
It is strongly recommended to connect metal parts of the luminaire to
the CosmoWhite ballast, to reduce EMI and to obtain maximum lightning
stroke protection.
The CosmoWhite ballast has reinforced insulation, which protects these
metal parts connected to the ground connection of the ballast against
becoming live in any normal operating or fault mode.
To comply to the insulation double insulated criteria, not only must the
gear be compliant, but also the luminaire precautions for the lamp cables
must be taken.
Important notice:
To have maximum protection against lightning strike surges, it is strongly
recommended the below points are followed:
• The distance from the lamp contacts to any metal part connected to
the earth terminal of the gear must be > 8mm and preferably 10mm
or more
• The lamp wires must have the classification ‘double-insulated’ or
‘reinforced insulation’. Putting a sleeve around the two wires to
keep them close together will reduce EMI and improve the lightning
stroke robustness
The dotted line (see Figure 25) shows the difference between
insulation grounded and double insulated.
3.9 Containment safety
As in the case for CDM-lamps, the chance for non-passive failure of
the CosmoWhite arc tubes at end-of-life (by e.g. wrong ballast choice
or short circuit situation) cannot be excluded. When the burner shatters,
this can lead to cracks or even shattering of the outer bulb.Therefore,
CosmoWhite lamps must be operated in fully enclosed luminaires,
able to contain all the broken hot parts of the lamp.
However, it must be noted that the occurrence of non-passive failures
is very unlikely.
OEM Design Guide Philips Cosmo 17
3.10 Optical design
The surface finishing of the reflector material to be used for the
CosmoPolis lamps should be faceted, patterned or matte.These
surfaces will mix the light from the arc to a more homogeneous beam.
Arc color differences exist due to the different molecular weights of the
metals and deposits of the metals in the bottom of the arc tube that will
be projected in the beam, so the reflector needs to mix the light well.
The volume of the optical system is also important. If this volume is
too small, the lamp and possibly the ballast will run too hot and will
experience short life. Critical temperatures as specified in section 3.4
should be taken into account to guarantee the life specifications for
lamp and ballast.
Reflection surfaces parallel to the lamp are not advised, as they will
reflect the heat of the lamp back to the parts inside the lamp.The
critical parts are: the whole arc tube and the ‘getter’ disk (the square
metal object with the grey round metal deposit). When this disk is
thermally overloaded, the area around the disk will rapidly blacken.
The arc tube is sensitive to any extra heat load at both ends. This
might overload the seals causing a crack in the ceramic or leaky glass
seal.The body cannot have an extra thermal load as it will accelerate
certain chemical processes inside, leading to shorter life of the lamp.
When designing a fixture, first measure the lamp temperatures as
explained in the beginning of this chapter. However, this only yields
temperatures on the outer bulb, not inside the lamp.
As an extra check on the optical system, a cool-down curve of the
lamp temperature can be found in the following way:
• The temperature after switch off of the lamp should be recorded
for about 20 seconds. In some cases a strong discontinuity in this curve
from 1 to 3 seconds after switch-off can be found. This might be
an indication of extreme heating of the thermocouple and hence
the lamp surface by reflection from the optical system, which should
be avoided.
For HID-lamps, often a comparative measurement of the lamp voltage
inside and outside the luminaire is used to check whether the lamp
is too hot. As the lamp is surrounded by a narrow reflector and/or
housing, a lamp voltage rise can occur due to trapped or reflected
heat. For lamps operating on an electromagnetic ballast, an increase of
the lamp voltage in the luminaire results in a lamp power increase that
leads to a further temperature increase of the arc tube and an even
higher lamp voltage increase. For lamps operated on an electronic
ballast such as CosmoPolis lamps, the lamp power is stabilized by the
ballast such that the voltage rise is much less.
18 OEM Design Guide Philips CosmoPolis
However, for CosmoWhite lamps, it has been found that the lamp
voltage does not increase significantly, as long as the reflector/housing
is sufficiently sized, i.e. for bulb temperatures not exceeding the values
in Table 5 (see section 3.4).
As such, for CosmoWhite lamps the lamp voltage is not a
good measure to assess whether a luminaire is critical with
respect to lamp temperature or not.
Even if there would be a minimal lamp voltage rise, the lamp power
does stay constant (consequence of the use of an electronic ballast).
Therefore, light technical properties like luminous flux, color rendering,
and color coordinates remain practically unchanged in a luminaire.
3.11 Summary: Attention points for luminaire design
• All CosmoPolis lamps have to be operated in fully enclosed luminaires
• The lamp-luminaire combination must be tested in the most
unfavorable situation in order to measure if certain points of the
lamp (or luminaire) do not exceed the given temperature limits
• Lifetime of the lamp will be shortened when a CosmoPolis lamp
is operated in a reflector that is too small in volume or that is not
well designed
• The CosmoPolis lamps are designed for universal operating position,
but the light-technical properties (e.g. color temperature) are
optimized for horizontal burning position. Therefore, light-technical
properties in vertical burning position can slightly differ from the
specified values
• For the optical system, the use of a surface finish which mixes the
light (e.g. faceted reflectors) is recommended
• Make sure that the temperature on the Tc point of the ballast is
10ºC below the maximum rated temperature. This will ensure the
nominal lifetime is achieved
• For optimal surge/lightning protection of the system make sure
there is sufficient distance between parts in the luminaire connected
to the lamp output on the ballast and parts connected to the
ground connection of the ballast
• Make sure that the wiring inside the luminaire complies with the
description in this guide

4.4 Spectral power distribution
For the spectral power distributions of CosmoWhite 60 and 140W
(see Figure 30 and 31).
Figure 30: Spectral power distribution CPO-TW White 140W
4.5 Operating positions of the lamp
The CosmoWhite lamps are “universal burning”, which means that
they can be operated in both horizontal and vertical applications.
However, the light-technical properties are slightly different in vertical
burning position compared to the horizontal position. When rotating
the lamp from the horizontal towards the vertical position, the color
temperature, CRI, luminous efficacy and lamp lifetime drop compared
to the horizontal data.
5. Ballast specification
and application
5.1 Grounded and double insulated
Figure 31: Spectral power distribution CPO-TW White 60W
5.1.1 Grounded
In grounded applications the outside of the ballast is allowed to have
touchable metal parts that can become live in case of a ballast failure.
Also the earth connection of the ballast is allowed to become live in
case of a failure.The safety in this case is guaranteed by the fact that a
connection wire for ground is present and this will make sure voltages
will not rise higher than a few volts.
5.1.2 Double insulated
There are two kinds of electronic ballasts with a functional ground.
The first is the type which has a plastic housing and a ground connector
that is not double isolated.This type of product can be used in a double
insulated luminaire. But, when the ground terminal is connected to metal
parts in the luminaire, these metal parts need to be double isolated.
Reason for this is that because the ground terminal is not double
isolated it can become live in case of a ballast failure.
The second is the type that has a plastic housing and also a double
isolated earth terminal.The CosmoPolis ballast is of this type.
If it is used in a double insulated luminaire, metal parts of the luminaire
can be connected to the earth terminal. No double isolation of these
metal parts is needed.
For information on design of the luminaire regarding this subject
see Chapter 3.
5.2 Lightning strike/transient protection
The CosmoPolis ballast has a protection against 10kV surges in
combination with the ability to direct high currents to ground for a
short period.This decreases the number of failures on a main line in
case of a lightning strike.
Lightning strikes
The Advance CosmoWhite ballast is designed to withstand 10 surges
of 10kV / 5kA (IEEE 62.41.2 between [L&N]-G and lmap holder NOT
connected to GND).
For information on design of the luminaire regarding this subject
see Chapter 3.
OEM Design Guide Philips Cosmo 23
5.3 Lifetime
The lifetime of the electronic ballast mainly depends on its
temperature, as explained in section 3.4.2. The CosmoPolis
ballast types have a nominal lifetime specification of 60,000
hours with 95% survival rate.
Figure 32 to the left shows the lifetimes of typical electronic ballasts.

• Mains:
Orange connectors (not polarity sensitive)
• Metal parts of luminaire:
Purple connector (tied to the green earth ground connector inside
of the ballast)
Connector of the ballast is suitable for wires AWG 20 to 12. Insulation
must be stripped from the wire for 0.50 inch.
Solid wires can be pushed in directly. Release the wire by depressing
the release button and pulling the wire.
Stranded wires should be pushed in while depressing the release
button. Release the wire by depressing the release button and pulling
the wire.
5.5 Operating in abnormal conditions
Temperature switch-off behavior
If the CosmoPolis ballast is used at excessive temperatures, thermal
protection will protect the ballast against damage. The ballast will be
switched off by this thermal protection.
The thermal protection becomes active at a ballast Tc point
temperature of 93ºC199°F.This the minimum value at which it can be
activated. There is a tolerance range on the activation temperature.
The minimum activation temperature must be used to determine at
which luminaire ambient temperature the ballast will switch off.
Over voltage
The CosmoPolis ballast can withstand the following situations:
400V
5 minutes
350V
2 hours
320V
48 hours
Note that high mains voltages adversely affect ballast lifetime.
The ballast switches off in case the mains voltage exceeds 277V.
This means that in the over voltage situations the ballast will switch
off within time periods as mentioned above.
5.6 Installing wiring
Installing the ballast wiring must be done with care.The lamp output
must in no case be short circuited with the ground (when the ballast
is in operation) or mains (when mains voltage is present) because this
will destroy the ballast.
