inside the searchlight housing. When inserting and connecting the lamp, care must be
taken to prevent any twisting or bending forces from being transferred to the lamp body.
Insure proper current connections and polarity. Incorrect polarity will immediately dam-
age the lamp. Remove the protective cover and tighten the lamp using a lamp extractor
tool (Perko Figure # 9582 000).
WARNING!
Before taking the protective cover off the lamp, put on a
protective mask, chest protector and leather gloves.
If the quartz body of the lamp is accidentally touched, clean it with alcohol and dis-
tilled water. Wear appropriate safety equipment when doing this job. Do not use clean-
ing rags (or material that can leave a residue). To avoid damage to the quartz envelope,
clean with a lint free cloth or a soft paper product.
OPERATION OF LAMPS
Before initial operation, polarity of the electrical connections should be checked to
avoid reversed polarity. Reversed polarity can destroy the negative electrode in seconds
making the lamp unusable.
Lamps operate best at their rated current. Over the life of the lamp, current may be
increased to its maximum value to compensate for loss of light, however, initial opera-
tion must begin at the rated current to avoid excessive arc instability (commonly
referred to as flicker). The output of the lamp can be reduced by operating the lamp at
its minimum current. NEVER EXCEED THE MAXIMUM CURRENT VALUES STATED
IN THE TABLE.
INSTRUCTIONS FOR USING XENON LAMPS
The lamp housing must be closed during ignition and lamp operation.
WARNING!
Never look directly at an operating lamp. This may damage your eyes. Always use
appropriate eye protection. Avoid direct exposure of the beam on your skin. Burns
can result.
The base temperature of the lamp should never exceed 230 degrees C. Forced air flow
should never be directed at the lamp. When operating lamps with forced cooling, care
should be taken to assure that the velocity of the cooling air stream is correct.
Convection cooling air velocity at the lamp equator should be 10 ft./sec. Fan cooling air
speed should range from 16 to 32 ft. / sec. and should continue for at least 5 minutes
