LIGHT BEAM CONTROLS


The width of the light beam is controlled by the larger, 
middle knob on the sides of the lamp arm.

The height of the beam is controlled by the knob near 
the bottom of the illumination tower.

The top knob of the light tower 
rotates the light beam.

The wheel on the back of the 
light tower is used to put cobalt 
and green filters in the light 
beam.
