O.K. I am reading in some recommended material to use a 5.0 UVB light. I went to the pet store and they had 5.0 and an 8.0. They recommended 8.0 for dragons. Is this right? What is the difference??
Also. I bought a probe thermometer awhile back. It was reading properly, I guess, and my heating was in good shape. Now it reads low temps even right underneath my basking light. Do bulbs go bad or themometers.
