I did the same thing, but didn't know about the afterglow until I had the damned thing hanging from the ceiling. I didn't test to see if it would fog paper, but being blue/green, I assumed it would have *some* effect. I also assumed it would fog film, so I changed it. The only way to know for certain would be to do some testing, as I think different tubes have different amounts of glow. The ones I had seemed very bright - I could read the black print on my white t-shirt. On a related note, I have a lightbox next to my paper safe that has fluorescent tubes in it, but I can detect no afterglow. I think the frosted plastic "glass" is enough of a filter to block it out. You might be able to fashion something like this for your fixture. tv - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
