Our pool, just about complete now, has a pair of Pentair 12v Intellbrite 5G lights in it. Last night, I wanted to see what they looked like, and the look is absolutely awesome.
However, we noticed a noticeable "buzzing" sound coming from the equipment pad when the lights were on. I had no idea what this sound was last night when we were looking, but this morning I remembered we had 12v lights, which must have a transformer to operate. Sure enough, I looked this morning, and saw the transformer, which must have been emitting the buzzing sound last night.
Is it normal for these transformers to buzz when the lights are on, or is this something I should have my PB look at?
