Another way to make a quick disconnect for lighting systems is to use an extension cord. Cut the cord so the male end is short, coming from the light fixture. The cord with the female end is longer and is wired into the ballast/power source. Having the female end be the power source is a safety measure because if the open prongs of the male end was powered...

shocking.
As I think about this, if there is not an inline ballast, then have the cut male end from the fixture plug into a complete extension cord. I hope this makes sense.
