Simulating accurate caustic effects within Iray can be cumbersome and computationally expensive, but Iray Water Caustic Lights provides a workaround. Within this set, you will find a set of 3 lights: a point light, a spotlight, and a rotational spotlight. The spotlight and point light project a simple, caustic gobo, which can be modified and recolored as needed. The rotational spotlight provides a set of adjustable lenses that can be randomized and animated.

The lights are completely drag-and-drop; simply load them into the scene and point them in the right direction.
