Articles about Convert Fluorescent to Electronic

I need advice about fluorescent ballasts replacements. I have 3×48″T12 lamps installed in a line: one 2 tube fixture,and a single tube fixture The lamp of the single fixture will not illuminate (even after changing the tube). Can a light fixture with a electronic ballast share the same circuit with a light fixture with a magnetic one?
