b) Lamp Optimization

The lamp orientation and optimization must be adjusted after every lamp change. This

procedure centers the lamp in the reflector. Proper optimization will increase lamp life and

ensure a bright crisp output. Improper optimization may add a yellow tint to the lamp output

and reduce intensity. The minimum deviation amount is 1.0mm. Running the fixture within a

lower deviation can cause damage to the lamp and/or lens.

The Focus Spot 250™ lamp holder is aligned at the factory. However, due to slight

imperfections in all lamps, fine adjustments will improve light performance. Please follow the

procedure below for proper lamp optimization:

1. Using either a DMX controller or the control panel on the unit, strike the lamp and

focus the light on a flat surface (beam open, white, no gobo, no effects).

2. Center the hot-spot (the brightest part of the beam) using the 3 adjustment screws.

Turn one screw at a time to drag the hot-spot diagonally across the projected image.

If you cannot detect a hot-spot, adjust the lamp until the light is even.

3. To reduce a hot-spot, pull the lamp in by turning all three screws clockwise 1/4-turn at

a time until the light is evenly distributed.

4. If the light is brighter around the edge than it is in the center, or if light output is low,

the lamp is too far back in the reflector. "Push" the lamp out by turning each the

adjustment screws ("A, B, C") counterclockwise ¼-turn until the light is bright and

evenly distributed.
