WARNING: The plastic shields preventwater spray from splashing on theglass reflector and lamp. Do not

operate light unless plastic shields are inplace. Shields provide protection in case oflamp explosion.

Reflector: The dichroic-coated reflector reflectsdesired light and allows unwanted heat to passthrough the back. The shape of the reflectorcollects light from a wide angle and produces ahigh intensity glare free pattern approximately3” (7.6 cm) to 8” (20.3cm) wide of distancesfrom 18” (45.7cm) to 36” (91.4cm). Each part ofthe reflector becomes a light source, whichcontributes to the total pattern. The large sizeof usable pattern requires less light headrepositioning during an operation. The reflectoralso offers other demonstrative advantagessuch as greater energy efficiency, cooler lightand increased lamp life.

Lamp: The miniature quartz halogen lamp lastsmany times the life of conventional lamps. Itsself-cleaning process maintains constant lightintensity. The lamp may be replaced in secondsand requires no tools. Refer to the “Mainte-nance and Adjustments” section for lampreplacement.

CAUTION: The handle and the lighthead become very hot during

operation. Do not touch these areas while lightfunctioning.

One light may be placed over the headand the other in front to overcome difficultlighting conditions. Variable length columnsare available to accommodate 8' (2.44 m) to13' (3.97 m) ceiling height installations.

Track Assembly: The track assembly con-sists of a plywood pallet, an aluminum trackchannel, aluminum dress covers, panels andend caps. Proper installation to ceiling sub-structures will ensure drift-free and vibration-free operation of the light head.

Transformer Box: A fuse located on the endof the transformer is provided for circuitprotection of the light. The single track lightrequires a 3AG SLOW BLOW, 2 amp, 125 Voltfuse (little-fuse #313002/S). The dual tracklight requires a 3AG SLOW BLOW, 4 amp,125 Volt fuse (little-fuse #313004/S).

Trolley: The trolley rolls freely at the touch ofthe hand and serves as the portable andpositive mount for the light column throughwhich the electrical wiring passes.

Vertical Column: The column length andassociated power cable determine heightoflight and are the only two variable factors withdifferent ceiling heights. If light is moved to anew office with a different ceiling height, anew column and associated power cable maybe purchased to easily modify the light.

Column Stop: The entire arm and light maybe rotated approximately 322° with respect tothe column. Location of the column stop maybe varied to provide optimum operatingpositions. To adjust, refer to the "Maintenance& Adjustments" section of this manual.

CAUTION: Do not rotate arm morethan 360° with respect to thecolumn or twisting damage to the
