Have you turned the sphere to which the IES emitter is applied the right way?

IES works best with small 0.5 cm diamenter sphere rotated to face the wall to be lit.

I think depending on the IES file you use and its measured shape, the object you apply it to will turn black. You could just add a second weak emitter material to it to avoid this I guess.
