Each frame from 1 to 30 display a different IES file.
(last light on the right is an Octane light for reference, but can't have animated IES)
I use random primitive mesh in the scene for testing purpose, but keep in mind that using only one polygon face for one IES light is probably the better choice.
To have one IES light per face like for light 1 and 5, make sure you use "normal space" coordinate in the projection node,
this is very handy if you need for example a wall of LED
