On all the rabbit trails of this thread:
I've always hated CFLs. Count me among those who can't figure out why they fail so quickly when they are supposed to last for years. We are replacing the ones in our kitchen light and basement light on probably a yearly basis. I chucked them and went back to incandescents for now.
If a very efficient incandescent came along, I'd gladly use it. But for my RV, I'm sticking with the LEDs I bought last year to replace all the incandescent bulbs. As others have said, I'm sure it will be years before we see anything available commercially.
About mercury: In 5th grade science class, we built a barometer, which had a large glass tube about 4 foot high sitting in a large beaker full of mercury. We'd take the mercury out and pour it on the table - one huge blob and poke at it...with the science teacher right there encouraging us. She lived to a ripe old age and I hope to as well.
