Alright, thanks. I'll try to see which one will work better for my game.Or any other lighting effects script. Take note though that Lighting scripts are a huge performance hogger. I suggest going far from them unless really needed.
Anyway, it depends on what you want to achieve... If the lights are static (not moving), I suggest just using overlays. They can do much better effects and consume negligible performance than lighting scripts. There is also BustedEd's tutorial for evented lightings.
