How can I get one light to turn on while the other turns off automatically?
This might be a complex question, but I don't know where else to ask.
I am working on a lighting system for my aquarium. I have a 17W fluorescent bulb and a blue 12V LED strip to act as a moonlight for the aquarium. The 12V LED light has already been wired up to a converter, so it will run off of house current.
My question is this- how can I wire things up, to have my LED strip to come ON automatically when I turn the 17W fluorescent bulb OFF? and vice versa.
Is this even possible? I plan on having this setup on a timer switch as well.
Thanks in advance.

Another solution would be to use a three way switch. Power in on the common terminal. The two switch controlled hots on the travellers. With this setup one light source will always be on. You could install a single pole switch ahead of the 3w if the lighting needs to be off.
