Align Lamp for Flat Field
The design of the VL2000 Wash wash luminaire optical system is based on a flat field. A flat field is
one where there is no detectable hot spot.
After a new lamp is installed, it will be necessary to align the lamp to optimize the beam. Knobs
located at the luminaire’s backcap will allow adjustment.
WARNING: Backcap and adjustment knobs will be HOT during lamp operation. Wear gloves and/or
use tools to prevent burns.
To align lamp:
Step
1. Using internal menus select Lamp test to set beam. See
“Controls Operation” on page 52
for more information. (If using console, set intensity to 100% and adjust diffusion to
produce a tight beam.)
Step
2. Position beam on a white wall at a distance of 10' to 20'.
Step
3. At backcap, using Vertical and Horizontal knobs, adjust hot spot to center of beam.
Step
4. Using Focus knob adjust beam for flattest field.
