light source only
when the cover is
closed. Position
the device horizon­tally. The xenon lamp
particles can reach
temperatures of up
to 1000 °C (1832 °F).

Risk of fire, burns,

5. Operation

5.1 Installation

Please ensure that the light source is placed onto its feet and is positioned horizontally; otherwise thermal
changes may occur, reducing the operating life of the xenon lamp.

The xenon lamp is filled with hot vapor and is subject to gravity, which has a horizontal pull.

The xenon lamp ignites with a series of short (> 1 microsecond) high-voltage pulses of up to 10 kV. This
sounds like a series of mouse clicks. An ionized arc is created between the electrodes.

5.2 Commissioning

5.3.2 Light Output Stability

Fluctuations in the light output of up to 5 % and occasional gas flares or bright flashes of red or pink light are
normal.

Xenon lamps contain small amounts of metals. These metals are present both in liquid and in solid form and
may show as dark-reddish or reddish-brown spots or as a film on the inner surface when the xenon lamp is
cold. These phenomena are normal and do not affect the operation of the xenon lamp. They disappear once
the xenon lamp has been put into operation.

The discharge between the two closely positioned electrodes, which are sealed in a quartz glass envelope,
generates light through an electric arc. During operation small amounts of metals are heated to a liquid state,
producing the vapor required for the desired light color.

Light generated in such a way is very intense.

Appropriate precautions in relation to light intensity and heat must be taken:

- The Endolight Xenon light source operates at very high temperatures and under extremely high pressure.

Particles can reach up to 1000 °C (1832 °F) and can cause burns, fire or damage to property. Proper instal­lation, cooling and ventilation is required to ensure reliable operation.

Page 18

Operation

CAUTION

Do not look directly
into the light source
and avoid direct
contact with the light
source. Risk of inju­ries; damage to

the eyes or skin

NOTICE

Do not touch the
xenon lamp. Only
touch the lamp
socket.

Skin oils from finger­prints or other impu­rities on the xenon
lamp will decrease
lamp performance
or cause premature
failure of the xenon
lamp.

- Operate the xenon lamp only in its closed light source housing.

- The UV light from the xenon lamp can cause serious eye damage and skin irritation.

- Always let the xenon lamp cool off for 10 to 15 minutes before replacing it.

- Handle the xenon lamp with caution.

- Do not touch the xenon lamp. Only touch the lamp socket. Skin oils, fingerprints or other impurities on the

xenon lamp will decrease the performance or cause premature failure of the xenon lamp.

- Switching the FOT Xenon light source on and off in rapid succession will shorten its life span.

- Xenon lamps are highly efficient and sensitive to changes in temperature and external influences. Varia-

tions in performance and color may occur.

- After switching the xenon lamp off it should be left to cool for 10 to 15 minutes before turning it back on to

ensure a trouble-free startup. If you do not observe this waiting period, the xenon lamp may not ignite be­cause the pressure within the chamber is too high and no arc between the electrodes can be generated.

- The more stable the mains voltage, the longer the service life of the xenon lamp and the better the quality

of the emitted light.

- Avoid any damage and mechanical disruptions when installing, assembling or replacing the xenon lamp.

- The maximum operating temperature must not be exceeded and good ventilation must be provided at all

times.

- The high quality of the light output is typically retained during the lifetime of the lamp at 75 % or more of its

original value.

- Xenon lamps use high-voltage short-term pulses to initiate operation.

- This model is a DC (direct current) xenon lamp. Ensure proper electrical wiring to prevent damage to the

xenon lamp.

- It takes about 24 seconds to achieve full light output. After the ignition process, the mixture of metals,

halogens and rare earth elements must first heat up to melt the solid components and let them evaporate.
During the warm-up phase instabilities may occur, such as a flickering or blinking of the lamp.

Endolight FOT Xenon

Page 19

Operation

Because a variety of factors influence the service life of the xenon lamp, the stated life span is only an aver­age value.

The xenon lamp is considered defective if it does not start or if the light yield has fallen to half its original
value. The operating life of the xenon lamp depends on how often it is started. If the xenon lamp is switched
on and off frequently in rapid succession, the service life is reduced by approximately 50 %.

If the xenon lamp is operated in a continuous mode, its service life improves by up to 30 %.

Decommissioning, Disposal

10. Decommissioning, Disposal

The light source is manufactured in accordance with RoHS Directive 2011/65/EU.

The xenon lamp consists largely of quartz glass and it contains a small amount of mercury and inert gas.
Argon and xenon are used as filling gases. In addition, small quantities of other materials are used, but they
do not play a significant role. The electrodes are made of tungsten. They are coated with nickel and molybde­num and fused into the quartz glass.

Disposal must be carried out according to the following steps and in line with local regulation guidelines for
the disposal of hazardous waste:

Mercury may leak when the xenon lamp breaks.

CAUTION

Risk of poisoning,
respiratory distress,
health hazard

Do not breathe in any mercury vapor.

Mercury vapor is toxic and can damage your lungs and nervous system. If mercury leaks out, air the room
thoroughly (for approximately 30 minutes, depending on room size and conditions). A high concentration
of vapors may cause short-term symptoms such as pneumonia, chest pain, shortness of breath, coughing,
gingivitis, salivation and stomatitis. When the substance comes into contact with the skin and/or eyes it can
cause redness and irritation.

Inhalation of quartz may lead to shortness of breath and coughing.

Inhalation of tungsten dust may cause irritation of eyes, nose and throat. The essential trace element molyb­denum is no longer processed correctly which can lead to disorders of the stomach/intestinal tract.

Remove the xenon lamp only after it has cooled off completely (10 to 15 minutes).

Remove the broken xenon lamp from the lamp socket.

Remove any remaining mercury using adhesive tape, paper or a syringe.

Place any material that was in contact with mercury into an airtight non-metallic container, and dispose

of it in line with official regulations.

Ensure that these steps are carried out with adequate ventilation, and wear protective goggles and pro-

tective clothing.

Clean the affected areas with a mild soap or detergent and water, and prevent any further contact. Con-

sult a doctor if necessary.
