We just got our new beardie today! I bought a kit set up, only because it was a wicked sale, and cheaper than buying just the tank itself. It came with a 75 watt basking bulk (which is not heating his basking spot to 110 degrees, which I knew it wouldn't), and a 13 watt desert UVB bulb (again, bought it knowing full well I needed to get fluorescent tube lighting). They were out of a lot of lighting, and told me I could come home and set up his habitat, and then order the lighting on amazon prime.
I am getting so confused with all the lighting though... can someone help me and tell me exactly what I need to order? We went for a 20 gallon tank with a mesh top, which we will keep until he gets bigger and then switch him to a 40 gallon.
As for UVB preferences I prefer the Reptisun T5HO 10%. The fixtures come with a 5%, you will have to buy the 10% separately.
Buy a 2ft fixture so when you get the 40, you will already have the UVB for it.
The fixture can be placed on top of the screen as long as your basking spot is within 10" of the light.
