Color/Gobo Control
The VL2500 Spot Luminaire’s color system is composed of a CYM color mixing mechanism and a
fixed color wheel. The following sections describe these components.
CYM Crossfade Color Mixing and Dimmer
The color mixing mechanism is made up of three graduated color disks: Cyan, Yellow, and Magenta
(CYM). These disks provide full-spectrum color crossfades from pastel to saturated colors. Also
included on the color mixing bulkhead is a graduated glass dimmer wheel for smooth time-controlled
fades from full light output to absolute black.

Color/Gobo Wheel Positions
The standard configurations for color and fixed gobo wheels
are: all color filters installed on Wheel 1 (wheel nearest lamp)
and all gobos installed on Wheel 2 (wheel nearer to front lens).
These wheels each have 12 positions, one being open.
All rotating gobos are installed on the Rotating Gobo Wheel
(nearest to front lens). This wheel has six positions, one being
open.
Color and gobo wheels offer partial frame control and various
spin rates in either direction.
