Hello, I am about to purchase my beardie in the next few weeks, will be my first one! I've done a ton of research, gathered everything I'll need for him and got the terrarium all set up. The only thing I seemed to have messed up on, is that I bought a Reptisun 10.0 UVB Compact. I knew I needed a reptisun 10.0 but I didn't realize the huge difference with the tubes vs. the compacts. So now I am obviously going to buy another, but I really want to save money where I can, without impacting his health of course. So the three things it seems most people recommend are the Reptisun 10.0 T5, T8, or the Mercury bulbs. IF the mercury bulbs are just as good, that seems like the cheapest option for me. So I guess my question is, which one do I get?
