Optimizing the Lamp
Optimize the lamp after replacement, or if there is a “hot spot” of brightness anywhere other than
the center of the light beam.
1. Orient the fixture so that the beam will
project onto a flat, white surface at least
10 feet (3m) away.
2. Turn the lamp on. Ensure the light beam is
round and not oval. If necessary, adjust
the pan and tilt construct values until the
beam is round.
3. Adjust the focus until the edge of the light
beam is sharp.
4. Set the DIM to full (see Chapter 4: Fixture
Programming on page 41).
5. Locate the three lamp optimization screws (x, y, and z).
6. Look at the wall where the beam is projected and use the optimization screws to adjust the
lamp’s position within the fixture until the “hotspot” of brightness is at the center of the beam
and diffused. The
x and y screws move the hotspot. The center z screw adjusts beam
flatness.
