As this is an Exo Terra, it will be covered by mesh with the UVB outside the tank. I would recommend using an Arcadia UVFlood, mounted about an inch above the mesh, which will give a great gradient for Anoles. Then make sure you provide areas of open basking, interspersed with areas of cover, preferably from live plants.
For the plants, a 9 or 13w Arcadia Jungle dawn would be sufficient, mounted next to the UVFlood, then a Halogen on a dimming thermostat as a heat source.
