High Voltage Input and Output Microcontroller

I am new to this, but I am looking to regulate a few ballast controlled fluorescent lamps with a micro-controller. Everything I look at has a low operating voltage and below 10 volt input/output voltage. I want to have a/c hookup to the microcontroller with full power output to the ballast (when told to do so by the program on the chip). Am I misinterpreting what the input/output and operating voltages mean, or are high voltage applications of microcontrollers not too common? I was looking at some arduino products or something similar. Any direction or clarification is much appreciated.

Thanks,

Connor

The circuit you want will consist of a microprocessor IC controlling a flourescent lamp power supply controler IC, a HV transistor, a HV transformer, an EMI filter and a few other things.
