Lamp Adjustment
The objective is to achieve an evenly bright projection field, with the center slightly
brighter than the rest of the field. If this is the case, adjustment won’t be required.
The bulb position in the lamp head is pre adjusted but due to variations in the
different light bulbs, it may be required to re-adjust the bulb position.
Procedure (see illustrations below)
If available, place an empty gobo holder into the projector.
Focus the beam by positioning the lens barrel to achieve a hard edge beam.
Turning one screw tilts the lamp towards or away from the screw position. This is
used for centering the beam.
Turning all screws the same amount in one direction moves the lamp in or out of
the reflector.
All screws counter-clockwise: Hot Spot in center
All Screws clockwise: Dark Spot in center
Find a position where the dark spot just becomes an evenly bright center The
smaller the contrast between center and rest of the field, the better. An extremely
bright center (hot spot) can damage the gobo due to overheating.
