Long rectangular light looks wrong

Hi,

for my train interiors I tried to use long rect lights but I got a wrong look with a point light effect in the middle. I tested it at my test interior and it's the same. Could the light distribution be fixed for a more natural look?

Jonathan Knoefel I found the new version and install it. Hmmm, it's not the result I would expect.

If I move the light particular outside so that only a part is active, than the light distribution looks nearly perfect. Could this implement for the full used light?

And here the worst case - a long thin wall washer.
