I put a point light inside of a glass lightbulb (turned off multiple importance) and then put those in a collection and then instanced that collection within a Geometry Nodes network and put all of that in a collection. I think linked that collection into another scene.
At 100% scale it behaves like normal. At 200% scale it seems the light objects don’t scale up with the rest of the object and wind up inside of the mesh and no longer contribute to the lighting.
This screenshot is at 200% scale and the lights are inside of the glass:
This screenshot is at 100% scale and the lights are outside of of the glass:
The light strength is set to over nine thousand.
