[]Adjusted night sky brightness to vanilla values.
ABOUT MOD
This mod aims to fix the out blown lights in Fallout 4 both indoors and outdoors and remove skylights a.k.a FakeLights indoors. It does also remove bloom if you want to (look in file section). It goes very well with Unforbidable's Darker Nights. I'm using Darker Nights Level 1 with this mod and it looks great.
I've spent many hours tweaking for "correct" values in the lightning system so i hope it looks good in the whole game.
To remove FakeLights on the character and enemies go to Documents\Mygames\Fallout4\Fallout4.ini and under add this line
sStartingConsoleCommand=cl off or you can download ENBoost and disable it from there.
If you want to remove fog too you can also add setfog 1 0 like this sStartingConsoleCommand=cl off;setfog 1 0 however radstorm and misty days looks kinda wierd with all fog disabled, you may want to get a mod that disables just specific fogs.
INSTALLATION
1. Install Nexus Mod Manager
2. Download mod with Nexus Mod Manager and install it from there.

✅ Pros
- Massive community trust – 39,567 endorsements and 1.2M downloads speak for themselves.
- Simple premise: just tweaks lights, no bloat or extra features to fiddle with.
- Still relevant for many players despite its age – a testament to its quality.
⚠️ Cons

For Fallout 4 players who want a quick, no-nonsense lighting improvement without overhauling the whole game. If you're a purist who prefers subtle tweaks over big visual overhauls, this is for you. Skip if you need up-to-date mods or want extensive customization options.
💡 Beginner Tips
- Since it's an older mod, check if you have the latest Fallout 4 patches – you might need to use a compatibility fix.
