Abstract
A lighting fixture having a color-changing mechanism, such as a color wheel, for cycling through a plurality of colors, such as by rotating, at a first speed and a second speed. The second speed is faster than the first speed. A position pulse device, such as a position sensor, generates a reference position pulse when the color-changing mechanism is at a predetermined color or position. A circuit periodically generates a master pulse. A control device causes the color-changing mechanism to cycle through the colors at the second speed when the reference position pulse is generated after the master pulse.
