Relight

The Relight node takes a 2D image containing normal and point position passes and lets you relight it using 3D lights. Essentially bypassing the need to return to a 3D application and re-render the lighting, Relight provides a quick and interactive way to relight a 3D scene in a 2D environment.

Relight works by applying a 3D shader to a 2D image using the normal and point position passes stored in separate image channels, and lets you attach and manipulate a 3D light (or multiple lights via a Scene node).
