Lamp adjustment
The lampholder is aligned at the factory. Due to differences between lamps, fine adjustment may improve
light performance.
Strike the lamp, open the shutter and the iris, set the dimmer intensity onto 100 % and focus the light on a
flat surface (wall). Center the hot-spot (the brightest part of the beam) using the 3 adjustment screws
"A, B,
C”
. Turn one screw at a time to drag the hot-
spot diagonally across the projected image. If
you cannot detect a hot-spot, adjust the lamp
until the light is even.
To reduce a hot-spot, pull the lamp in by turning
all three screws
"A, B, C”
clockwise ¼-turn at a
time until the light is evenly distributed.
If the light is brighter around the edge than it is
in the center, or if light output is low, the lamp is
too far back in the reflector. "Push” the lamp out
by turning the screws
"A, B, C”
counterclockwise ¼-turn at a time the light is
bright and evenly distributed.
Focusing
