I wonder, what is the deleterious effect, Richard.....something we can see today or something we have to wait years to see? I have one of these in my darkroom since Christmas... my darkroom now smells like... well... a waterfall. It's a pleasant, clean smell but I wonder if that's not a hint of ozone. It does not smell like the ozone smell you get with arcing of an electrical current. I know waterfalls have an extremely high level of electrons and I was associating the smell with the electron levels. J.R.
