How do I turn a primative into a light only?

How do I turn a primative into a light only?  I wanted to convert a light in the scene from a primative but I do not want the primative to be visable.  How do I do that?

In Iray, after applying the Emissive preset set the Cutout Opacity to a very small but non-zero value. That will, however, stop the light from being reflected too so it may not have the impact you desire.

Cutout Opacity value of 0.0001 will work
