I have several sets of flourescent lights in my kitchen which up until tonight, were all controlled by a wall switch. Today, I replaced several of the tubes and now, when I turn the switch on/off, only some of the lights come on. There are several other switches in the kitchen which we have never used but now they turn on/off the lights NOT being controlled by the master switch!!

It seems insane but it seems that previously, all of the fixtures were on the same circuit and not poof, for some reason they have been separated into different ones. I didn't do anything else other than replace some bulbs..

Can anyone help?!!
Thanks

You should never replace a subset of a set of fluorescent lights. You should always replace all of them at the same time.

Thanks for your reply..why would not replacing "sets" of the lights cause the problem I am experiencing?

Because the ballast fires up all the bulbs at the same time, and how one bulb reacts influences how the other bulbs in the same fixture react.
