No-texture 2D light?

I want smooth 2D lights, just like in 3D, but since it requires a texture to work, that means I would either need to make specific textures to specific scenarios or make a 2048x2048 texture that can be scaled as much as I want.

But I’m concerned that the first option is not viable and the second is going to cause performance issues, since I don’t actually need so much resolution in small lantern for example.

What’s the best way, then?
