Thanks guys for your response. For the time being, I will leave the lights on. I will assume that I will be replacing bulbs on a regular basis.
No problem with the F/C out side readings. I spent a couple of years in Italy and email frequently our winter temps (25C) to our friends in Turino with (3-4C) temps.
And yes, I don't understand the opposition to the metric system. it is so much easier than 29/64ths of an inch!!
