Ok so I ordered the Reptisun 10.0 bulb to replace the ReptiGlo 10.0. I got it, put it in and was so excited that Beardie had a new, powerful UV bulb. The problem is that every since I put the new bulb in, he stays in his log most of the day. He's healthy and eating well but refuses to bask. I'm not sure if it is a coincidence that he decided to hide after I got the bulb or if there is something wrong with the bulb. How would one know if there was a prob?
