As we were swimming all three pool lights turned off simultaniously. No fuse seems to be flipped, inside controls as well as board say the lights are on. We did replace one bulb three months ago. Any ideas?
BTW: 23,000 gallon, in ground pool, gunite, "regular lights" - not LEDs. And if you couldn't tell by my technical jargan, I'm a homeowner and first time pool owner (4years), who takes care of own pool and I must say- I feel a great sense of satisfaction by doing so!
