LAMP ALIGNMENT HOW-TO
Often, after a new installation of a lamp, you will find that there is an uneven field of light or what is
referred to as a hot spot. This is due to the most intense point of the lamp source not being positioned
optimally within the reflector.
There are three lamp alignment screws provided at the base of the projector head, behind the back
cover plate. Turning these screws allow you to
optimize the projection quality of the spot as well
as the overall intensity of the beam.
1. Project a white flood against any flat surface.
Preferably the surface should be white or
pastel in color.
2. Turning the lamp alignment screws, try to
position the hot spot in the center of the beam
as best as possible. This could require many
attempts on your part.
3. Once the hot spot is in the center of the spot,
do your best to turn all screws equally as to
affect movement up or down within the reflector.
4. As you move in and out of optimum lamp focus, you will see the hot spot either gets wider or
narrower. The goal is to either totally diminish the hot spot by having it widen and spread across
the entire spot or moving the hot spot so that it covers as much of the beam spot area as possible.
Power
Warning! Verify that the internal multi-tap transformer is set to match the line voltage applied and
that the proper fuse is installed for the appropriate voltage setting. All fixtures must
be connected to circuits with a suitable Earth Ground.
To determine the power requirements for
a particular fixture, see the label affixed
to the back plate of the fixture or refer to
the fixture’s specifications chart.
A fixture’s listed current rating is its
average current draw under normal
conditions.
All fixtures must be powered directly off a
switched circuit and cannot be run off a
rheostat (variable resistor) or dimmer
circuit, even if the rheostat or dimmer
channel is used solely for a 0% to 100%
switch.
Before applying power to a fixture, check
that the source voltage matches the
fixture’s requirement.
All fixtures must be connected to circuits with a suitable Earth Ground.

CAUTION!
This lighting
fixture comes
from the
factory with a
120V fuse pre-
installed. To
operate this
fixture in 230V,
please replace
the external
fuse with the
supplied 230V
fuse.
CAUTION!
Voltage selector switch is
accessible by removing the
front cover of the fixture.
Re-wiring of the transformer
should be conducted by a
certified electrician or
lighting professional.
