Vita lights are a full spectrum bulb very close to sunlight.
How much UV do they produce? I dont know.
Without a UV meter its impossible to tell.
I will be ordering a solarmeter in a week or so to test the T5 lights I am running to see if they put out any uvb. Reefkeepers claim they do.
With an icecap ballast you will be over driving the the bulbs, if you use normal output bulbs of 40w they will run 80-90 watts. More light, less life of the bulb.
A t5 54w bulb is said to hold its spectrum for 20 to 24 months!
I would run t5's if you use an icecap ballast and a zoomed 5.0 on a regular ballast. That would be full spectrum and uv for sure.
The t5's run hot enough to bask under if the chameleon can get 3-4 inches from them.
