The lights are too intense after last update, they don't look right, they look like more pronounced individualized light spots. Revert them back to previous brightness. The complaint was that the lights radius didn't reach far enough, not necessarily the brightness.
What game are you playing? I have never experienced anything but the darkness of utter despair in all of my houses, regardless of how many lights I have placed. It's like the light is just a picture of light. I can see it, but it doesn't illuminate anything.
