Redfoot Tortoise sun bulb?
I am a total newbie and I'm setting up a viv for my very first Redfoot tortoise. I am going to buy an Arcadia mercury basking lamp 100w. And I was hoping someone could suggest a sun bulb to use. I understand that it has to put out UVB and UVA. But I am getting really confused when looking to purchase on the net. What wattage should I be buying? I'd be grateful for any info and suggestions if you think this is the wrong basking lamp to go for.
