From the start I had decided to have the house wired for Christmas window candles. Although I wanted to be able to flip one switch and have them all come on, some of them are in bathrooms and are on a GFI circuit so it takes two switches. I bought the LED bulbs last year but things weren't far enough along to use them until this year.
I am surprised that C6 LED bulbs aren't more available. They are readily available online, but I have not yet found them locally. The LED's don't put out quite as much light, but they run much cooler and use maybe 1/10 of the electricity. They didn't even measure 1 watt each on my Kill A Watt. You certainly don't need to worry about singeing the window shades.
This year I ran the LED light strings around the porch and deck, but next year I'll probably get more energetic and run them up the gables and across the front of the house.
Our tree is from Balsam Hill. Although artificial, it's quite realistic.
The LED lights look just like the incandescent mini Christmas lights. The outer branches are moulded to resemble an actual tree and the inside of the tree is the cheaper twisted plastic strip branches. If you look closely at the enlarged photo you can see them, but they're not very apparent.
