Light Cut's of at a certain distance from the lamp, the lighted area "turns off when away from the lamp (not happening with vanilla lamps) maybe a bug/game limitation?

Yes that's one vanilla limitation (as far as i know) and possibly reason it doesn't exist in vanilla... i'll try to investigate that still.

yeah, thought so, i am also tinkering with it to see if i can narrow it down,but so far no luck

So far only things are reducing the light radius and / or not zooming too far. Not satisfactory...
If any better ideas i can include them of course.
