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. 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 spot 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
Your product is equipped with switch-selectable AC power setting.
Warning! Verify that the power select switch on your unit
matches the line voltage applied. 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.
