Dimming thermostat wise, habistat or microclimates are good. I'm not sure if you should plug the UVB into the any of the thermostats but have to admit I don't know the ins and outs of the new digi ones. All else fails get a normal dimming stat and a timer.
Go by what this lady has said and fail you shall not! Just to clarify she is correct on uv length and position, you want the 3ft version, not the 4f, for a 4ft viv.

Uv bulbs cannot be dimmed via a thermostat, you would need a dimmable ballast and a few hundred pound to buy one at that! If you still wanted two probes then I'd look at the new range from habistat, otherwise I can't recommend their old range enough and should drop significantly in price now I'd hope. You can then simply plug this in to a household timer for automation.
