A method of making an optical filter wheel of a device synchronizable with an internal, rotatable virtual reference wheel, created in a memory of a motor controller of the device, is disclosed. The method includes a single trigger event that initializes rotation of the virtual reference wheel. The controller determines the orientation of an optical filter wheel of the device and maintains an ongoing representation of said orientation over time. The controller controls the motor, which causes the filter wheel to become coincident with the virtual reference wheel after the trigger event. A self- contained light fixture is also disclosed, which includes an optical filter wheel driven by an electric motor that is synchronizable with an internal, rotatable virtual reference wheel of the fixture. The method and light fixture permits optical filter wheels of multiple light fixtures, which may be identical, to synchronize with one another.
