Page: 10 / 44

ESTABLISH A ROUTINE of periodically checking all electrical connec tions for tightness.
Loose contacts, particularly in the DC circuit, will cause overheating and damage the xenon bulb and other
components. Normal xenon bulb warranties allow no credit for bulb damage caused by overheating.
REFER TO THE BULB MANUFACTURER’S INSTRUCTIONS regarding bulb rotation.
Most bulb manufacturers recommend rotating the bulb 180° at 50% of warranty hours. After rotating the bulb,
operate at maximum allowable current for several hours, and then return to the nominal operating current.
IN THE EVENT of a bulb warranty claim, the bulb must be packaged in its original shipping
container, and returned with all required warranty forms completed. Contact the dealer through whom the
bulb was originally purchased for correct procedures and Return Authorizations.
IT IS A COMMON PRACTICE to replace the bulb at the expiration of its warranty period.
If a xenon bulb explodes in operation, the reflector and other lamphouse components are frequently damaged.
The xenon bulb manufacturer will extend no credit for a replacement reflector if the defective bulb is beyond
warranty. Explosion-damaged reflectors are to be returned to the bulb supplier , NOT Strong Entertainment
Lighting, unless the bulb was supplied by Strong.

ARC STABILIZATION MAGNET
THE XENON BULB used in the Gladiator IV lamphouse requires use of an arc stabilization
magnet. This magnet is located below and behind the reflector. The magnet is preset at the factory and should
not require adjustment. Should it become necessary to adjust the magnet, the following procedure must be
followed. Observe all bulb safety procedures when working in the lamphouse compartment.
A NORMAL ARC should appear as shown in Figure “A,” and represents the correct magnet
position. Figure “B” shows the position of the arc when the magnet is too low; Figure “C” shows the position
of the arc when the magnet is too high. Condition “B” or “C” will cause arc flicker. If flicker is apparent in the
projected spot, raise or lower the magnet on its slots as required to position the arc as illustrated in Figure “A.”
THE MAGNET must always be installed with the longest portion of the magnet
uppermost (nearest the bulb), and with the NORTH (N) pole pointing toward the operator side access
door. Reversing the magnet will cause bulb flicker, and may inhibit bulb ignition. In new equipment,
the magnet is normally in the center of the adjustment range. Changes in the magnet position are required
only
to correct an improperly burning arc (Figure “B” or “C”).
ANY REPLACEMENT MAGNET should first be installed in the center position of the
adjustment range. Raise or lower the magnet as required to center the arc as illustrated in Figure “A.”
