Focus Adjustment
The effect focus can be varie d by moving the projection lens. This may be accomplished without opening the
unit case. Two small thumb screws on the upper or lower surface of the unit secure the lens mount. Loosen
both screws slightly, (but do not remove either screw) and use one of them as a handle to slide the lens mount
forward or back until the desired focus is achieved, then tighten both thumb screws securely.
Filter or Gel Installation
A slot for a color filter is provided at the front of the Firelight. Due to the high light output from the fixture,
only glass or dichroic color filters are recommended. Typical gel filters will tend to bleach or burn quickly due
to the high light output from the fixture, and would require frequent replacement. Color filters should be cut to
two inches by two inches, or 50mm square in size, and be no thicker than 1/16 inch, or 1.5mm. A
thumbscrew at the front of the unit retains the filter. Both color filters and shaped apertures may be used to
change the general character and appearance of the projected display.
To install or change a filter, disconnect power to the unit, remove the thumbscrew next to the output port, and
slide the filter into the slot in the case top or bottom nearest the thumbscrew. The filter should be pushed into
the slot until it stops, or at least until the edge of the filter or mount is clear of the thumbscrew hole. Reinsert
the thumbscrew and gently tighten it to retain the filter. If it is possible to invert the Firelight unit when
installing a filter, the filter can be simply dropped in or out of the slot after removing the thumbscrew. Be sure
to replace the thumbscrew before turning the Firelight right side up to hold the filter in place. Reconnect
power, then aim and focus the unit for normal operation.
