Small tweak to the ambient lighting within the Vault 88 cavern, it allows for a much more natural environment with less dark patches as well as eliminating the amount of lights needed to achieve a satisfactory look.

Note: As this increases the ambient lighting, it does mean that the cavern is unnaturally bright even without player placed lights.

Goes well with: Vault-Tec SimuSun Lighting & Settlement Objects Expansion Pack by ccmads 

Compatibility: Should be okay with most mods.
