For a full size adult beardie's tank (about 4ft L x 2ft W x 2ft tall) I recommend the following lighting:
>>>> basking globe = 80W - 100W MVB or par38 clear colorless incandescent / halogen style spotty
>>>> UVB , a 24W t5 UVB tube rated at least 10%UVB with a reflector behind it mounted about 8-10" from beardie's basking spot.
substrate:
>>>> loose laid ceramic floor tiles , or slate tiles are very good and ultra easy to clean simply by lifting out the soiled tile and giving it a blast with the hose.
