Simu-Sun

Simu-Sun is a technology used in vaults to simulate the effect of the sun. According to a Vault-Tec advertisement, Simu-Sun reproduces the feeling of being outside, with only a fraction of the sunburn potential. 
It was one of the technologies on display at the Vault-Tec demonstration exhibit at the Museum of Technology in Washington, D.C. when the Great War began.
