We used a simple on/off wall thermostat inside the incubator to control a small bulb.

Are you looking to have a closed loop control system? Just trying to figure out how to actually drive the bulb with a specific voltage that is precisely controlled by microcontroller? You haven't said what type of controller you are using. More information would be very helpful.
