Align Lamp for Flat Field
The design of the VL2000 spot 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 for the flat field. 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 “Lamp” on page 72
for more information. (If using console, set intensity to 100%, open beam
size iris and focus for hard edge.)
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 best spot.
