Step 5:
Gently slide the field lens back and forth on the rails until you get the desired width of the
beam and then finger-tighten the thumb screws.

Moving the lens towards the lamp narrows the field angle of the beam.
•
Moving the lens away from the lamp widens the field angle of the beam.
Step 6:
Loosen the two knurled thumb screws on the focus lens holder.
Step 7:
Gently slide the focus lens back and forth on the rails until you get the desired focus of
the beam and then finger-tighten the thumb screws.

•
Moving the lens away from the lamp softens the focus so that the edges are soft.
