STRONG INTERNATIONAL'S XENON GLADIATOR IV Model 47070 is a direct current
follow spotlight system complete with a lamphouse, xenon power supply, op t ical system, color boomerang,
and base stand assembly. The spotlight assembly consists of the arc lamp, variable focus lens system, color
boomerang, and base. The separate xenon power supply completes the installation. Only these special power
supplies furnished by Strong Entertainment Lighting can be used with the Gladiator IV. For installation and
operation of the power supply, see the instruction manual furnished separately.
THE XENON LAMPHOUSE utilizes a xenon bulb designed for horizontal operation, and a
deep ellipse metal reflector, as a light source. The reflector operates in a fixed position, and is dichroic ("cold")
coated to reduce heat in the projected light. A lens blower and heat filter, mounted in the spotlight optical
system, further reduce heat at the projection lens and color media.
ONLY XENON BULBS specifically designed for horizontal operation should be used in this
follow spot. The Gladiator IV lamphouse is designed to use the LTIX-4500W-HS watt bulb, and replacement
bulbs (4000-4500 watt, not exceeding 4500 watts) must be certified as 100% interchangeable with this bulb.
Lower wattage (2000-3000 watt Type "HS") bulbs may be installed in the Gladiator IV using an optional anode
support collet and cathode adapter kit supplied by Strong. All required bulb cabling and contact clamps are
provided in the xenon lamphouse.
ADJUSTMENT CONTROL for the xenon bulb is located at the rear of the lamphouse behind
the access cover. The adjustments control the horizontal, vertical and focal movement of the bulb.
INSTRUMENTATION of the lamphouse includes a DC ammeter and a running time meter.
The ammeter continuously displays the operating current (amperage) applied to the bulb; pressing the VOLTS/
AMPS switch below the ammeter momentarily indicates the DC voltage at the arc. The running time meter
records the elapsed hours of the bulb. A second rocker switch controls lamp ON/OFF.
TWO LAMPHOUSE COOLING BLOWERS are internally wired and operate on AC voltage
derived from the xenon power supply. These blowers are required to maintain a safe operating temperature
at the bulb seals. A third blower cools the optical system and the center-mounted color boomerang. These
blowers operate continuously until the xenon power supply is de-energized.
THE LAMPHOUSE is supplied with a 13 foot (4 meter) cable containing the DC leads, the
AC control wires, and the ground wire. The cable terminates in a mul t iple-pin, quick-disconnect plug keyed
to mate with the receptacle on the power supply cabinet.
WHEN TRANSPORTING THE SPOTLIGHT, it is necessary to remove the xenon bulb and
place it in its original shipping container to prevent breakage. See the SAFETY PROCEDURES section fol-
lowing, and permit only trained and authorized person n el to handle the xenon bulb.
