Spot Light lights the whole room?

So Im trying to make a room thats kind of like an interrogation scene with the blinding lights pointed at you. But the problem is that my Spot Lights start lighting the entire scene rather than what their cone is pointed at. It looks fine before I build the lighting though.

This is what it looks like before the lighting is rebuilt, which is exactly how I want it to look:

This is what it looks like after I build the lighting (not what I want):

Any help would be very much appreciated!

Looks like global illumination.
on the spotlight in question, try changing “Indirect lighting intensity” to 0, then it doesnt contribute to GI
