UV protection question
I've got a lot of items displayed in my home office that are in "uv protected" cases (mostly plastic, some glass). Has anyone ever tested to see how good this protection actually is? I am not too worried, since I have heavy curtains and a bookcase in front of the window, and the lights are only on for a few hours each day. I was just wondering if the advertised protection is really that effective.
