After a new lamp is installed in the luminaire, it will be necessary to align the lamp to optimize the
beam.
WARNING: Backcap and alignment screws will be HOT during lamp operation. Wear gloves and/or
use tools to prevent burns.
To align lamp:
Step 1. Set intensity to 100%.
Step 2. Position beam on a white wall at a distance of 10 to 20 feet.
Step 3. If frost is in beam, use console or internal luminaire menu controls to remove. Focus to a
hard edge. Be sure that beam-size iris is completely opened.
Step 4. Using three alignment screws (as indicated with Red Arrows in Figure 2-5 ) adjust hot spot
to center of beam.
Step 5. Check color uniformity as follows:
a. Check color uniformity as follows:
b. a. Position 60% Cyan or 60% Magenta filter in beam.
c. b. Verify that hot spot is centered (if lamp is misaligned, color will be concentrated to
one side of beam). If hot spot is not centered, readjust lamp using lamp alignment
screws.
