I just installed a set of 4 under-cabinet fluorescent fixtures. These are GE's with T5 tubes. The fixtures come with a 3-prong plug so they have to be plugged in to their own receptacles or daisy chained together. I plugged in the first one and daisy-chained the other three with the connecting cables supplied with the fixtures. I want to be able to be able to turn them all on from a wall switch instead of individually with the little rocker switches on each fixture. But I noticed a warning label on both the power cord and the connecting cables that said something like "not for interrupted power" or something like that. Does that mean I cannot turn these lights on with a wall switch? I was going to leave the first one plugged in to one side of a duplex receptacle and replace the other side of the receptacle with a switch. Why wouldn't that work?
