I have my house set to 5 for lighting and it is absolutely dimmer then it was, HOWEVER I believe it's due to how the lights work now, before they seemed to behave as if walls didn't exist and "shined through" for lack of a better word but now if there's a wall the light is stopped on the side it's on (the light reflection on the wall is blinding). More realistic yes but not something I gave a chocobos backside about and my kitchen & bedroom areas look like they're being lit with something not cleaned in a hundred years.
