How to edit the light shape and brightness attached to an object mesh?

[Dimensionlord1]

Hello, so the children of atom bottle lanterns have always bothered me how they use the incorrect light and are not very bright to be a reliable light source. Inside the nucleus the same bottles light the whole area up nicely, and have a solid light. Whereas the versions we get craftable for settlements have a weird fractal light which makes no sense given its just normal bottle and should produce a solid glow, and they are VERY weak - barely producing any light. I've tried looking through the creation kit to see if there is a way to change the attached lights with no luck. Not sure how to go about changing the lights on the object, and haven't had luck finding any information or tutorials anywhere.
