1. A luminaire, comprising:
a head comprising a light source, wherein the head is rotatable about a tilt axis (T) and about a pan axis (P);
a first pan absolute encoder;
a second pan absolute encoder;
a controller configured to determine a pan position of the head, wherein the controller is configured to determine the pan position of the head based on first rotational position information received from the first pan absolute encoder and second rotational position information received from the second pan absolute encoder; and
a drive pulley and a driven pulley that are connected by a belt, wherein a ratio of a first gear or diameter of the driven pulley to a second gear or diameter of the drive pulley is a non-integer number.
