Align Lamp For Maximum Beam Irradiance
After a new lamp is installed in the luminaire, it will be necessary to align the lamp to optimize the
beam.
WARNING:
Backcap and adjustment 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. Using console or internal luminaire menu controls, set zoom to zero and focus to a hard
edge. If installed, be sure that beam-size iris and shutters are open.
Step
4. Using three adjustment screws, adjust hot spot to center of beam (
Figure 2-8
).
Step
5. Check color uniformity as follows:
a.
Position one of the color stages at 30% of maximum. (Cyan or Magenta work best.)
b. Verify that beam color is uniform (if lamp is misaligned, color will be concentrated to
one side of beam). If color is not uniform, readjust lamp until color is uniform across
entire beam field.

Note:
The nature of the CDM lamp used in the VL1100CD ERS Luminaire prevents it from restriking
when it is hot after use. It takes approximately 15 minutes for the lamp to cool enough to restrike.
* Do not remove or use to access lamp.
