Got a call the other day from a lady. She lives a few blocks away from my home and had noticed my landscape and lighting and was impressed. So she called me because her previous landscaper had recently gone out of business and she wanted a new one. Specifically, right now, she needed someone to replace a light fixture that had been broken. So I went over and I was in the middle of replacing the fixture and she mentioned that she is always having to replace the light bulbs in her fixtures. So I said, "Hmmmm. That shouldn't be happening. Lemme check it out." I went and got my Fluke and hooked it up. And what'd'ya'know.... 17.6 Volts!!!! " "Holy smoking lightbulbs, Batman! Yah, I bet you were replacing some bulbs!!!" Needless to say I corrected the situation. Unfortunately, the yahoos who installed the system installed a transformer that was a little TOO large for this job. They had installed all of the circuits on the 18, 19, and 20 taps. The lowest tap was a 12V tap. Even on that tap, I was getting 11.6, at the fixture. Which is acceptable. But I bet with a 11V tap I could have got it down to the 10.6-11V range, which I would have preferred. Anyway, that was hilarious. Thought I'd share the story.
