Go up to 120-130 on the basking spot, around 100 on the warm end, mid-80's on the cool end.
Don't use a basking spotlight that doesn't create a hotspot at least as large as the lizard's body. Might have to use two, depending on how far above the basking site the lamp is. Lizards will move off a basking site when their core temp is where they want it, and rapidly heating a small area on a medium-large sized lizard can cause thermal burns. (One light should do for a baby just fine, though.)
