Those were two of the studies that I found within a page or two of google scholar.

Thanks. I will need to expand my vocabulary when using scholar. I didn't use any variation of "transmitting" or "transparency". Dumb. Lesson learned.

Evaluation of UVB reduction by materials commonly used in reptile husbandry - Michael Burger - 2007 - Zoo Biology - Wiley Online Library requires a fee... I cant afford it. Bugger. The joys of college.

Now I feel stupid and poor

Added it to the list of articles to read when I can...

And... I don't feel quite as stupid. There are many articles dealing with additives to glass that absorb/block UV, or UV blocking plastics, but very few that actually refer to or measure UV transparency, and those only mention it in passing. Looks like most researchers are interested in blocking UV. Not much interest in allowing it through, apart from flora/fauna related interests.
Interestingly, http://www.guardian.com/stellentdev/.../gi_004941.pdf only provided manufacturers specs. Lots of information on glass, but no independent studies. Looks like "Evaluation of UVB reduction..." moves to the top of the reading list.

Did you check for this through your university library system? They may already be paying for access to it - as a result you could access. I know that our university (a rather small one) provides access. You could also request an interlibrary loan for this article (probably free maybe 3 bucks for the copy).

Go to your library page search for the Wiley Library database then find the Zoo Biology journal.

If that proves unsuccessful pm me.

I will definitely try that. Now that I think about it, I have barely touched the school's library system. They definitely have intersystem loans. I'm going to see what they have. Thanks for suggesting that. Its strange, I guess mostly because of the convenience of google, I don't think of using the library. I am going to change that now!

Good answer!

Keep in mind, your student fees pay for things like access to the journal in question and many many others. Our uni provides access to all sorts of things that many people don't know about but pay through the nose for (e.g., access to tons of high end software through remote desktop services).

This is what I use......... not sure if IKEA is in the US.....................

As most of you know I put real importance on providing UVb for all my frogs. I made up a lamp a few years ago that did the job but was a bit of a pain to use - bring a chair to rest it on to light some of the viv.

So I decided that this week while it was half term that I would 'build' something more practical. We had been over to Ikea and Global light (£14) caught my eye as being perfect for adaption. It bends and twists in all directions and fastens to any shelf and all of my vivs are on some sort of shelf I thought I'd give it a go.

Here's the lamp before I 'adapted it.

Then using the Arcadia parts I already had

Lampholder

Reflector

and bulb D3+ 10%UVb

Then it was just a matter of removing the lamp fitting and rewiring in the Arcadia lampholder which fits really neatly on the swivel head that the Ikea lamp comes with.

Here's a close up of how the original wiring that is internal to the lamp fits the Arcadia lamp

and finaly a couple of shots of the new UVb set up in action - I am really pleased with it and it will make UVb day (once a week each viv gets one hour of UVB lighting) so much easier.

here it is on the Retic viv
