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 double-ended HMI

®

metal halide bulb mounted transversly in a xed, deep

ellipse type metal reector. The bulb has an expected life of (500) hours of operation, and it is advis-

able to have a spare bulb available for each unit.

THE SPOTLIGHT is shipped with a yoke adaptable for truss mounting. An optional

folding oor stand assembly or tripod base are available through Strong International Dealers.
Interchangeable lens mechanisms are supplied in Long, Medium and Short throw congurations,

and are readily mounted to the TrussTrouper as the application or venue requires.

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 sup-

ply are controlled by means of xture-mounted 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 intensies light output as the spot size is reduced from ood to
spot. The two 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 Entertainment
Lighting and OSRAM Dealers. Use only the OSRAM 1200W double-ended 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,

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 le damage claims.

THE HMI BULB, if ordered with the unit, is included in the accessory kit packed with
the spotlight. DO NOT touch the quartz envelope when handling the bulb; ngermarks 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 loosening
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 reector and insert the bulb through the
reector 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
horizontal position and pin in place. The oor stand may then be moved on its casters to desired
location. IMPORTANT: Once the oor 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 oor.

INSERT THE POST of the yoke assembly into the nylon bushing at the top of the

oor 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 semicircular friction plate of the spotlight saddle

(see Figure 2, Item 41) 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 spotlight head can be adjusted by the amount of torque applied to

the lower, spring-loaded braking 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 (see Figure 2, Item 66). 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 xtures.

Truss mounting the TrussTrouper will depend largely on its application in any given venue.

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 tted with a plug acceptable for the local electrical supply. See the Equipment Data

Plate for the correct voltage before connecting the unit. Sustaining line draw of the TrussTrouper is

(12) amperes; observe local electrical codes regarding line protection.

ENERGIZE THE AC LINE by closing the POWER circuit breaker at the rear of the
spotlight head, and the cooling fans will operate. Close the LAMP switch and the bulb will ignite.
Allow one to ve minutes for the bulb to reach full intensity. Rotate the three adjusting screws below
the lamphouse base pan to center and focus the bulb inside the reector. Alternate adjustments while
observing the spot until the light eld is as at 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 rmly 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 reector regularly using a clean,
dry cloth. If excessively soiled, a good, spray-on commercial glass cleaner may be used. The bulb

envelope may be cleaned with alcohol on a clean cloth, and rinsed with distilled water.

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 ow, 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.

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 specications listed below
may serve as a guideline when rst 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. Use the fade-out chopper blades to

ROTATING THE FADE-OUT CONTROL will

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.
