I was just wondering what % UVB rays I need for my RES. I've been shopping around for his new set-up and equipment and realized the cheap lights have a low uvb %. I never even looked at %, I just made sure the lights were uva & uvb in one, which is what I would like. But, while I was on the PetCo web site I read a customer review that said a few of the bulbs were too low on uvb and don't bother buying them. So, how high do I need the UVB to be?
