Before I put up my flourescent lighting many years ago, I researched how museums and archives protect artifacts. I was especially concerned by all the stories of color fading on plastics due to extended exposure to UV. All my ceiling lighting pass through UV sheet film from GAM which has long supported the TV and movie industry, and selling products used by museums:
LEDs are not known for generating any significant amount of UV so it is now the safe choice for museums, archives, and train rooms.
If there is any doubt, you can always add an ultraviolet protective film to the lens of the LED light fixture.
