I question that you really have a 220 volt flourescent fixture. These flourescent fixtures usually come in 120 volt or 277 volt. 120 volt is usually found in a dwelling, other single phase wiring designs, or even 3 phase wye connected three phase 110v/208v.
The 277 volt flourescent is usually found in the three phase wye connected 480 volt wiring systems.

Check you name plate rating and confirm the voltage rating of the ballast. Once we know for sure what you have then we should be able to provide some guidance.

Remember that 277 volt flourescent ballast are not compatable with any single phase system that is rated less than 480/277 volts without installing a tansformer to make it compatible. The transformer would most likly be cost prohibitive in this described post.

See ya soon on a repost

Run a rigid or flexible conduit between the fixture JB and the switch, and run 4 insulated wires (EG 2 red, 2 Black), none grey or white, and a ground if necessary.

Use a 2 pole switch.

Another way would be to get a 2 pole relay with either a low voltage or 115 volt coil,
and use conventional wiring to control the coil, and wire the relay to be between the power and the fixture.
