The RingArray addon is an elegant intuitive solution for simply and rapidly creating circular arrays from any source object, light, camera etc.    Typical workflow for creating arrays of meshes means either manually copying, setting the pivot and rotating objects after doing the angle math. Or creating a linear array modifier, creating a second curve modifier, creating curve, sliding the numbers etc.  And even then the end result is bent objects, rather than linked duplicates.
