Have some way to create limit area to light actor?

Hello, i wanna know if is possible create a limitation to specific light actor by BP or any other set up. I get some problems with lights that are overlaping mesh face even with the high res lightmaps and corrects uv’s, and i think that maybe i can create a limitation to specific light actor to not overlaping the walls ( in this case ).

Thanks for your atention.

I would look into light channels
