Weird light effect on sprites

I’m stuck in a couple of issues, that are beyond my level of expertise. I’m just trying to add basic point light over lit sprites.

How to remove this flare?

And why does point light illuminates more to the left than right? o_O

Bump bump…

Dudes, don’t use sprites as backgrounds. Make lit surface material, apply it on plane and you won’t have any issues.
