spot lights

I have added three spot lights to my scene arranged as if they were above a pool table. When I rise the intensity of one light it deminished the intensity of the other lights. If I drop the intensity of one of the lights the intensity in the others go up. I’m not fully understanding why one light is effecting other lights in the scene in such a way. Is there some limitations with lights in Unity as far as the number you can have in a scene?

Solved. I was not in fantastic mode.
