The ultra vitalux is a much more powerful light than the 6% Arcadia lights most of us are using over our cages everyday. How many cages can it light at one time?

Leland, as you may already know, this bulb that Andreas is using is a very powerful UV emitter with a spot effect (halogen as opposed to linear bulb).
To that point, it could only light one cage at a time in its area of spot effect.
In addition, it seems this bulb is only made and sold for European use.
I will say that I am using the 6% Arcadia bulb over my Parsons cages. The bulb is 4" above the screen in a 5' tall cage. The animals closest perch gets them within 10" of that top of screen, with an average reading from a Solar meter of 45 µW/cm².
That being said, they are seen to bask directly in that UV light very minimally. As Andreas info would suggest, it does not seem they need a large amount of UV exposure as we are used to with other species like pardalis.
In addition, to make sure all info is clear, I am providing supplemental D3 in the form of the Repashy LoD product once a month and indoor Minerall once a month.
Hope that provides you some comparable info in regards to the Arcadia Bulb you are using.
On a side note, I use them for all of my different species and I do not believe that they would lead to Edema, at least I have not witnessed that. I would look elsewhere such as gut load and other areas for over use of vitamins.
