Please don't troll to hard as I'm new to using forums and have only posted one other time. Here's the deal. I spent months researching for my new beardie. First I ordered a uvb all in one mercury bulb. Then upon reading lots, decided to get an arcadia uvb tube t5 and a heat lamp instead. Yesterday got my dragon. Temps were all good. then at night turned off my lights. This morning I went to turn on the lights. The heat lamp is fine. The uvb bulb flickered as I turend the dial on. It then won't turn on. I tried reinserting the bulb, putting the bulb in different sockets, nothing. I was waiting to return my UVB heat bulb. It took Reptiles R us THREE weeks to get me my uvb bulb. What should I do? Should I put the mercury all in one bulb in and just wait for the arcadia bulb to be replaced? my dragon's name is Sarge, he's two months old and a few days and he is in a 36 x 18 x 18 enclosure. Thanks in advance for your help. If any experts can help, myself and my daughter would appreciate it. My email is [email protected]. Thanks in advance from BC canada
