Greg,
My home was built in '41 with a fireplace in the living room. When I moved in there was an old fake log set in it - the kind that has a motor driven drum with red/orange printed plastic covering. You put a lightbulb inside and it's supposed to similate flames. But the noise of the motor kind of kills any ambience, lol.
Around 1975, the kitchen and one bedroom of the house were remodeled into a continuous kitchen/family room, with a fireplace added in the family room. There was another fake log set in that fireplace - this one used thermal curents from the light bulb to spin the drum. That fireplace has never seen a real flame, and I've kept it that way. In fact although I enjoy a fire on a rainy night, I've never lit a fire in either one (the original one from '41 of course has seen plenty of fires). I picked up a cheap insert on Craigslist a while back, but it's so ugly (think thin brass plating over steel) that it's been sitting the carport ever since.
As part of weatherizing the home I serviced the dampers so they close properly, and also fitted plexiglass inserts into the openings. You can't tell they are there with the screens in place. I know they are doing the job because the thermally driven fake log set won' work any more - there's not enough air circulation in there to create a thermally driven air flow.
The only time I exercised bad candle ettiquette was when I was in high school and a girl friend gave me a handmade candle - one of those big ones - about the size of a coke can. It was a dark blue some some sort of abstract design on it (it was SF in the 60's). I set it on the end table by my bed and lit it. Then I fell asleep, waking in the morning to a nearly completely consumed candle, flame very low. Luckily nothing caught fire, but after that I've been very careful with candles.
Nowadays I don't even have many incandescent bulbs at home. Nearly all the lighting is fluorescent, which of course is somewhat safe, temperature-wise, than a hot traditional light bulb. Of course the fireplace fake logs use incandescent, though.
