The lightning from those lamps looks weird (like the circle in the ground is too big...?)
Those lamps do look wierd. I assume you're using env_projected texture? If so then use a different material, and alpha, something with a very feathered edge.
If it's not that, then your lightmap scale is way to high. I would keep it at 16, just so it wouldn't take so long to compile, and your file size would stay lower. :P
The circle isn't the worry its the fall off.
lighting looks seriously unrealistic!!!
