Align Lamp
The design of the VL3500™ Wash luminaire optical system allows for a flat or peaked field. A flat
field has no detectable hot spot. A peaked field has more intensity at the center of the beam than at the
perimeter.
After you install a new lamp, align the lamp to optimize the beam. Use the knobs on the luminaire
backcap to make the adjustments.
WARNING: Backcap and adjustment knobs are HOT during lamp operation. Wear gloves to prevent
burns.
To align lamp:
Step 1. Strike lamp.
Step 2. At Menu Display, select
Test
and then select
Lamp
. This setting facilitates lamp
alignment by disabling the pan and tilt motors, opening the dimmer, and opening the internal
lenses.
Step 3. Position beam on a white wall at a distance of 12 to 20 feet.
Step 4. At backcap, using X, Y and Z adjustment screws, adjust beam as required.
