PREFACE
THE STRONG TrussTrouper 1.2 Type 41080 is a high intensity, lightweight follow
spotlight designed for high performance and ease of operation and portability. The light source is an
OSRAM 1200 watt HMI Metal Halide bulb mounted transversly in a fixed, deep ellipse type metal
reflector. The bulb is warranted for (500) hours of operation, and it is advisable to have a spare bulb
available for each unit.
THE SPOTLIGHT is shipped with a yoke adaptable for truss mounting. An optional
folding floor stand assembly, and overhead Hanger Kit, are available from Strong International. Lens
mechanisms are available in Long, Medium and Short throw configurations, and are readily mounted
to the TrussTrouper as the application or venue require.
THE SOLID STATE POWER SUPPLY is mounted below the head assembly. The
power supply and lamphouse are forced-air cooled by built-in blowers. Lamphouse and power supply
are controlled by means of fixture-mounted pushbutton switches at the rear of the base pan.
POWER REQUIREMENT for the TrussTrouper is 120 V.AC, 15 amperes, 60 Hertz.
Approximate line draw is 12 amperes. A 220 V.AC, 50/60 Hertz model is available under Type
Number 41080-03 or -04. A 12 foot, three-wire power cord is mounted to the power supply.
THE OPTICAL SYSTEM, designed for left- or right-hand operation, includes a vari-
able focus lens mechanism which intensifies light output as the spot size is reduced from flood to spot.
The (2) rear mounted controls operate the fade out/douser and the iris. Control levers for the six color
self-cancelling boomerang are located on the top of the housing. A pattern slot for gobos is accessible
in front of the iris.
REPLACEMENT BULBS are available through authorized Strong International and
OSRAM Dealers. Use only the OSRAM 1200W HMI in this unit. Bulbs returned for warranty
adjustment must be returned through the original supplier, shipped prepaid, with all relevant warranty
papers completed and enclosed.
IF AT ANY TIME you have a suggestion, or desire aid in securing anticipated results,
write directly to STRONG INTERNATIONAL, 4350 McKinley Street, Omaha, Nebraska 68112.

INSTALLATION - OPERATION
INSPECT THE UNIT upon receipt. Any damage must be reported to the freight
carrier immediately. It is the responsibility of the consignee, not the shipper, to file damage claims.
THE HMI BULB is included in the accessory kit packed with the spotlight. DO NOT
touch the quartz envelope when handling the bulb; fingermarks will burn into the vessel, reducing
light, and contributing to premature bulb failure. Handle the bulb by the metal base caps only. The
HMI bulb is not polarized, and the iginter lead can attach to either end.
DISMOUNT THE LAMPHOUSE COVER from the rear of the lamphouse by loosen-
ing the (4) captive screws. Loosen the top bulb mounting bracket and remove the threaded nuts from
the ends of the HMI bulb. Pull the upper bulb mount clear of the reflector and insert the bulb through
the reflector holes. Slide the lower bulb end cap through the lower mounting opening; attach the
igniter lead and secure using the knurled nut. Swing the top bulb mounting bracket over the upper end
cap; attach the upper lead, and secure using the knurled nut. Tighten the top mounting bracket.
IF USING THE OPTIONAL FLOOR STAND ASSEMBLY, drop the legs to the hori-
zontal position and pin in place. The floor stand may then be moved on its casters to desired location.
IMPORTANT: Once the floor stand has been positioned, lower the leveling feet to transfer the weight
of the unit from the casters to the leveling feet. If the unit is to be permanently installed, it is advisable
to remove both casters and leveling feet, and bolt the stand to the floor.
INSERT THE POST of the yoke assembly into the nylon bushing at the top of the floor
stand tube. Position the yoke for right- or left-hand operation (as desired). Place the spotlight head on
the yoke assembly, making certain that the friction plate of the spotlight saddle is between the yoke
and the brake clamping plate. Tighten the (2) handwheel knobs on each side of the yoke allowing
adequate end play for free operation, and tighten the (2) lock knobs. Vertical movement of the spot-
light head can be adjusted by the amount of torque applied to the spring-loaded clamping knob against
the friction plate.
SET THE BALANCE of the head assembly. Loosen the (2) hex nuts on each side
securing the saddle brackets to the spotlight base rail. Slide the spotlight head inside the slots until the
proper balance is achieved, and retighten the hex nuts.
THE SPOTLIGHT YOKE, as supplied, is designed for use with standard truss fix-
tures. Truss mounting the TrussTrouper will depend largely on its application in any given venue.
TT/02

THE TRUSSTROUPER SPOTLIGHT may be suspended from a ceiling or overhead
truss by means of an optional Hanger Kit. This kit is available through your authorized Strong Inter-
national Dealer.
ELECTRICAL CONNECTION for the 41080-01 or -02 (120 V.AC, 60 Hz.) requires
a 120 V.AC, three prong 15 ampere grounded outlet. The Type 41080-03 or -04 (240 V.AC, 50/60
Hz.) may be fitted with a plug acceptable for the local electrical supply. Cooling fans are either 120
V.AC or 240 V.AC and not interchangeable; see Data Plate on unit for correct voltage. Sustaining line
draw of the TrussTrouper is (12) amperes; observe local electrical codes.
ENERGIZE THE AC LINE as required. When the power switch at the rear of the
spotlight head is closed, the bulb will ignite, and the cooling fans will operate. Allow one to five
minutes for the bulb to reach full intensity. Rotate thethree adjusting screws below the lamphouse
base pan to center and focus the bulb inside the reflector. Alternate adjustments until the light field is
as flat as possible at highest intensity.
WHENEVER THE SPOTLIGHT is moved, either from one position to another, or
one show site to another, the bulb mount should be inspected at the new installation site to determine
that the bulb is firmly seated in its socket. The above bulb alignment procedure must then be repeated
after the bulb mount assembly is replaced.
MAINTENANCE
THE TrussTrouper requires very little maintenance to keep it in good working order.
Cleanliness is the most important factor. Clean the surface of the reflector regularly using a clean, dry
cloth. If excessively soiled, a good, spray-on commercial glass cleaner may be used. The bulb enve-
lope may be cleaned with alcohol, and rinsed with distilled water on a clean cloth.
THE COOLING FANS are permanently lubricated, and require no oil. Fan impeller
blades and intake grilles must be cleaned regularly to prevent restriction of air flow, particularly after
events such as tractor pulls or rodeos.
OPTICAL SYSTEM LENSES may be cleaned with an optical grade lens cleaner and
Roscoe Lens Tissue. Light lubrication of the lens carriage slide rods using WD-40®or equivalent may
be desirable; do not use graphite lubricants, and do not lubricate the iris assembly.
TT/03

OPERATION OF OPTICAL SYSTEM
THE OPTICAL SYSTEM of the TrussTrouper consists of a spot size selector, an iris
assembly to reduce the size of the spot aperture, and a fade-out chopper assembly to permit reducing
light output from full intensity to complete douse. The iris and chopper controls are mounted on the
back of the lamphouse and are fully accessible from either side of the unit. The spot size is selected by
setting and locking a control knob located on the right side (as viewed from rear) of the unit.
INSTALL A LENS MECHANISM compatible with the desired throw. The three lens
mechanisms are designated as Short, Medium, and Long Throw. The throw specifications listed
below may serve as a guideline when first setting up the TrussTrouper, but optimal performance at a
given throw distance may vary with ambient light levels, projection angles, and other variables unique
to the venue.
Short Throw 20 - 50 feet (6.0 - 15.2 m)
Medium Throw 40-100 feet (12.2 - 30.5 m)
Long Throw 50-130 feet (15.2 - 39.6 m)
IGNITE THE LAMPHOUSE and allow the bulb to stabilize. Open the iris to project
the largest aperture by rotating the iris control (left) fully counterclockwise. Open the chopper blades
by rotating the chopper control (right) fully clockwise. Rotate the spot size control knob (right side)
counterclockwise to unlock, and slide the knob forward or back to set the desired spot size. Lock the
spot size control at the desired point.
TO REDUCE SPOT SIZE, or to project a “head”
spot, rotate the iris control clockwise to the desired spot size.
The spot cannot be doused by means of the iris control; do not
force the control beyond its stop.
ROTATING THE FADE-OUT CONTROL will
decrease the light output, and dim the spot to complete douse-
out. It is adviseable to use the dousing capability of this control
to cut off the light between cues instead of extinguishing the
bulb. The HMI bulb requires a relatively long warmup period,
and repeated ignitions decrease bulb life.

OPERATION OF COLOR BOOMERANG
THE COLOR BOOMERANG is equipped with six color holders. Additional filter
holders can be supplied by an authorized Strong International Dealer.
TO OPERATE INDIVIDUAL COLOR FILTERS, engage the desired filter selector
lever. A rocker catch located in the color disc housing holds the filter in position.
TO RELEASE A COLOR, push the filter release button or engage another color, thus
releasing the previous color automatically.
NOTE: WHEN PLACING COLOR FILTERS in the boomerang, the less dense col-
ors (pink, amber) should be placed in the holders toward the rear of the boomerang (toward arc), and
those of greater density (red, green) should be placed in the holders toward the front of the boomer-
ang (away from the arc). Use high temperature filter material (RoscoLux®or equivalent).
COLOR TEMPERATURE REDUCTION FILTERS, required for use with televi-
sion and videotape, are available from theatrical supply dealers.
