Currently my pool and spa lights are on separate switches, one switch controls the spa light and the other switch controls the pool light...so I can turn them on and off separately right now. I was considering changing both bulbs to color changing LEDs and was considering rewiring them both to one switch, so that when I turn that one switch on...both the spa and pool lights come on simultaneously. What do you guys think? Also, for those of you with an attached spa...are your spa and pool lights on separate switches are one switch?
