I don't like using the artificial lighting any more than

I have to in the winter, because I'm still

leary of the neg. effect on the eyes. If your tort gets outside

most of they day, that's plenty of sunshine "tanked up".



I've read that 15 minutes of sunshine is equivalent to

8 hours under a tube UV light (the mercury based ones are

certainly more powerful, but not comparable to sun).

Plus I don't like to waste the mercury light any more than

I need to so it's put away for now. As finicky as the

Active UV lights can be, I'll probably be looking at the

new stuff in the fall.
