This may be the wrong category but I am not sure where to ask for help about my situation.
I am trying to make a hanging light bulb and it works but it’s very glitchy and unrealistic.

Maybe just anchor it? That should make it less laggy.
If I anchor it then it won’t be able to swing.
It looks like you are using SurfaceLight/SpotLight. Try to use PointLight and disable the grey part’s “CastShadow” above the light bulb if needed.
