Prefab asset lights differently in different scenes

Hi, thanks before hand for reading this.

I'm having trouble with a prefab asset, which is like a camera with some surrounding scenary. I use it in two scenes, one of which is a main menu scene and the other one is currently the only level of the game. The light is set at 3000 Lumen units, and you can see the light is much more stronger in the first scene than in the second one.

My guess is that this is one of those problems you can solve with just a click but I'm not seeing it. A short term solution would be to manually level the lighting, but I wanna know why this is happening

Thanks in advance for your answers.
