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
refered to as a hot spot. This is due to the most intense point of the lamp source not being positioned
optimally within the reflector.
Lamp alignment screws
There are three lamp alignment screws provided at the base of
the fixture. 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. It is advisable to even out the
screws prior to lamp alignment as described in the illustration.
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 get 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.
Disconnect the power cord before replacing a fuse and always
replace with the same type fuse.
Fuse Replacement
The fuse is located
inside this
compartment.
Remove using a flat
head screwdriver.
With a flat head screwdriver wedge the fuse
holder out of its housing. Remove the damaged
fuse from its holder and replace with exact
same type fuse. Insert the fuse holder back in
its place and reconnect power.
