[Sidefx-houdini-list] instance light + light mask

hello all. I hope this is a simple question.

I'm instancing a light to an object with one point ( because the  
light needs to be placed inside/stay with a translucent object  
animated in DOPs)
I also have other lights in the scene.

I want this one object to only be illuminated by the instanced light  
and not any other lights in the scene.
However, I'm not sure how to enter this in the light mask.

It seems that if I enter anything other than * I don't get any  
illumination on that object.
I've tried entering the instanced object and the source light  
I've also tried entering * and then eliminating lights with  a ^  
string ....

but unless I enter a wide open * I don't seem to get any illumination  
on this surface.

Any thoughts??
