We have the tubes with the black plugs on the ends installed at our historic site.  They were easy to install and seem durable.  It's very easy to change bulbs (as the old bulb just slides out of the tube and the new one slides in).  We purchased ours at ErgoMart which offers a GSA discount www.ergomart.com

However, is anybody aware if any independent tests have been conducted to determine if the tubes actually cut the UV that the manufacturer says they cut?  I looked for studies before I purchased; but, I couldn't find any so I opted to trust the manufacturer.

I have used both the thin wrap-around UV filters and the solid tube type with black plugs on the ends. The wrap around types were actually much easier to deal with in terms of handling but my understanding was that they were only effective for a few years - nothing like the 10 years described in the link you included. The only other thing that I remember about them - in the past at least - is that as some bulbs burned out the extra heat (typically at the ends of the bulbs) caused the filters to bubble and stick. Even though most - with effort - could still be removed from the bulb I always wondered if their effectivness was reduced. I am curious to hear others experiences.

Hi all,
Apologies for cross-posting.
I was wondering if any of you had experience/advice relating to wraparound UV filters for fluorescent tubes (like these, from Gaylord: http://www.gaylord.com/adblock.asp?abid=2424&search_by=desc&search_for=uv&mpc=WW).

Thanks!
