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
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.
