CMY color mixing
The CMY color mixing system is based on graduated cyan, magenta, and yellow color filters. A
continuous range of mixed colors may be achieved by varying the amount of each filter from 0
to 100%. Note that mixing 3 colors results in a loss of light - the light is blacked out when all 3
colors are fully applied. For maximum brightness, mix only 2 colors at a time.

Color wheel

The color wheel has red, green, and blue dichroic color filters plus a 5600K to 3400K color
correction filter and an open (no filter) position. The color wheel can be used independently of
the CMY system or together with CMY color mixing to increase color saturation. The wheel
scrolls in full steps.

On Narrow and Medium models, the beam angle can be varied remotely using a motorized
zoom feature. Depending on the optical configuration of the luminaire, the one-tenth peak
beam angle can be varied within the following limits:
• Exterior 1200 Wash Narrow, 14° - 31°
• Exterior 1200 Wash Medium, 20° - 50°
The zoom is disabled if the temperature inside the luminaire falls below -10° C (14° F).

The speed at which effects fade, that is, move from one position to another, can be controlled
in two ways known as tracking control and vector control:
• With tracking control, fades are programmed using the controller's fade time. The controller
divides the fade into small elements that the luminaire "tracks." The Exterior 1200 Wash has a
digital filter algorithm that averages several updates to ensure smooth movement.
• Vector control provides a way to program fades on controllers without programmable fade
times or cross-faders. With vector control, instead of breaking up the movement into many
small positions, the controller sends one position value and one speed value and the
luminaire's own software controls the movement. Vector control may provide smoother fades
than tracking control with some controllers, particularly when the controller is busy with a
large number of processor-intensive operations, and particularly on very slow fades.
You can select tracking or vector control using your DMX controller, but you cannot use both at
the same time.
