Can someone give me a brief breakdown of what lights are necessary for russian, red foots, or leopard tortoises?

I go to some pet shops and they have sulcatas under flourescent aquarium lights? I understand they need a bulb for uva/uvb, a basking light, and a night light for heat.

How many clamp lights and bulbs am I looking at here? Or do all these bulbs serve the same purpose? Doing some research Thanks!
