I have an artists lightbox that uses some type of chemical ballast to run the flourescent light and it smells horrible. I would like to rewire it using an electronic ballast similar to what is on my fish aquarium light. Would this be a simple proceedure? There is a little cylindrical screw in component on my fish aquarium light but there is also a rectangular square thing that the wires run through as well. What is this? Could I more or less copy the way the fish aquarium light is wired and be sucessful with the lightbox?
