Thanks - I am not having the problem AFAIK, but maybe I just need to look more. This is really just a curiousity for me and goes along with my LED lights hobby. That is why I asked if anyone had an old yellow lens I can borrow to test it out - then return it.

I don't think so, but then again, I have not really looked into the photon energy required either. Obviously there is some kind of photochemcail reaction occuring, but I am still unclear on exactly what it is. I would have originally guessed that it is the adhesive holding the glass elements together yellowing, but others report that it is the glass itself, so I am not sure.
I was going to first use 455nm (royal blue) to see if this works, then move down to 405nm (near UV) if needed. There are 365nm (UV ) LEDs out there, but since the UV lamp worked for Ovim, this is probably not needed.
