I was sick of having to plaster my vault rooms with lights just so i could see anything at all. My solution was to cut the falloff, fade, and increase the radius of all the lights buildable in the Vault-Tec DLC.

There's not much else to say, installation should be simple, either use a mod manager, or chug it into your data folder.

If you want to see just how much brighter the lights are check out Oxhorn's video: 

The changes to the lights in the current version are:
  • Radius set to 600
  • Falloff exponent set to .1 from 10 
  • Fade set to 1/2 of original value

Generally this means that the area where the lighting is constant is now 600 "units," the light extends farther while getting dimmer, and the transition between light and dark is twice as soft.

  • Reduce the radius on coloured wall lights, and normal wall lights to prevent clipping through walls 
  • Improve brightness on some lights to make tall atriums less spoopy 
  • Create "brighter" version so suntanning indoors is possible. 

There is a PC version on Bethnet if you prefer to download there, the mod ID is: 2396543

The name of this mod comes from FO3, where the tour through a simulated vault says that the vaults have "Simusun lighting," this was pronounced "Sim-u-sun" because it simulates the sun.
