1. Remove screws labeled X, Y and Z and pull out lamp socket plate.
2. If replacing the lamp, remove old lamp first.
3. Holding the new lamp by its base, align the pins on the lamp with the small hole in the socket and
insert the lamp squarely until the retaining clips on the lamp socket secure the lamp tightly.
4. Clean the glass/envelope of the bulb with an alcohol wipe or equivalent.
5. Holding the lamp socket plate, insert the tip of the lamp into the fixture with extreme care.
Navigate the lamp all the way until it reaches the reflector and the lamp base plate touches the
bottom plate of the fixture.
6. Align the screw holes and fasten the screws back onto the lamp socket plate.
7. Turn the fixture on and adjust the lamp alignment screws until the brightest most even area of the
beam is in the center of your spot. It may be necessary for you to use a controller in order to
command the fixture to display a white beam on a flat surface with no colors.

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.
