XG4/006
For use in a Gladiator IV lamphouse, it is necessary to remove the
anode lead (if attached) from the anode end cap of the xenon bulb.
Observe all bulb safety procedures and leave the bulb in its protective
cover. Grasp the bulb by the anode (+) end cap. Use small channel
locks or slip-joint pliers and grip the bulb lead tting at the crimp joint
nearest the end cap, and unscrew the lead. If the bulb manufacturer
uses a brazed rather than threaded connection, cut the lead from the
end cap, cutting as close as possible to the end cap.
The standard bulb support collet (7200285) measures 4-11/16 inches
(120mm) overall and is designed for a 4000 watt “HS” xenon theater
bulb. When using a smaller, lower wattage bulb, a longer support col-
let (7200638) measuring 6-7/16 inches (164mm) must be installed in
place of the standard collet, and a chromed cathode adapter (7201174)
must be mounted to the bulb’s cathode pin. These components are
included in the optional Bulb Kit 7201175, and both the collet and the
bulb adapter should be mounted prior to installing the bulb.
PRIOR TO INSTALLING BULB, PLEASE NOTE:

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reectorandotherlamphousecomponentsarefrequentlydamaged.
Thexenonbulbmanufacturerwillextendno creditforareplacementreectorifthedefectivebulbisbeyond
warranty.Explosion-damagedreectorsaretobereturnedtothebulb supplier,NOTStrongEntertainment
Lighting,unlessthebulbwassuppliedbyStrong.

 THESECONDMETHODoffocusingthexenonbulbistoprojectthespottothestage,and
workingwiththeabovelamphousecontrols,adjustthesecontrolstoobtaina“hotspot”ontheprojectedspot.
Centerthis“hotspot”ontheprojectedlightbymovingtheentirecontrolsectionaroundthetwothumbscrews.
Oncethis“hotspot”iscenteredintheprojectedlight,lockthecontrolinpositionwiththetwothumbscrews
andturnthecentersectiontoobtainaspotwithanevendistributionoflight.Rotatethelensspotfocuscontrol
knobtoobtainasharpedgeontheprojectedspot.

THESEADJUSTMENTSshouldnotbedisturbeduntilafterreplacingorrotatingthexenon
bulb.Atthattime,theprocedureonobtainingasmooth,roundblackspot,or“hotspot,”mayhavetobere-
peated.Replacethecoverplateoverthebulbpositioningcontrolsandtightenthe(2)thumbscrews.
 BECAUSEOFNORMALBULBAGING,andmanufacturingtolerancesbetweenindividual
xenonbulbs,itmaybenecessarytooperatedifferentlampsatslightlyhigherorlowercurrentsettingsto
achievebalanced,uniformlightoutputwhentwoormorespotlightsareusedinoneinstallation.Thisentails
aslightcurrentoutputadjustmentatthexenonpowersupplies.Seethepowersupplymanual.

 TOEXTINGUISHthearc,placetheLAMPswitchontheinstrumentpanelto“OFF.”The
lamphouseblowerswillcontinuetooperateuntilthexenonpowersupplyisde-energized.Allowtheblowers
tooperatefortenminutesbeforeturningoffthepowersupply;aforced-airbulbcoolingcycleatshutdownis
requiredbyallbulbmanufacturerstocomplywiththeirwarrantyterms.
 BEFOREOPENINGthelamphouseenclosureforservicing,allowtheblowerstooperatefor
twentyminutes,oruntilthebulbhascooledtoroomtemperature.
HANDLING THE SPOTLIGHT
 GENERALLYTHEBESTPOSITIONfortheoperatortostandisnearthecenterofthespot-
lightontherightside.Theangleoftilt,thesizeoftheporthole,andthelayoutofthespotlightpositionmay
dictateanotherlocation.
 EACHOPERATORwill,afterafewminutesofoperation,generallydevelophisownsystem
andpositionformostconvenientoperation.

THEHORIZONTALSWINGandverticaltiltareindividuallyadjustabletogivethedesired
degreeoffrictiontosuittheoperator.Thelockingclampsarelocatedontherightsideoftheyokeassembly.
 ANEXPERIENCEDOPERATORwillusuallykeeponehandonthespotsizecontrolhandle.
Thisallowsbothdirectingthespotandchangingspotsizesimmediatelyuponcue.Compressingthebrake
leverpermitsfreemovementofthelargelensforwardandback,andreleasingtheleverlocksthespotsizeat
