We're fairly health-conscious. I bake my own organic bread, feed us organic whenever possible, cook healthy meals, recycle and try to use environmentally friendly products. So it just made sense to switch to compact fluorescent (CFL) light bulbs a couple years ago.
But after two years of trying to use CFL's exclusively, I'm done. I have no desire to continue pouring money into extremely expensive bulbs that contain mercury (my kids have knocked over lamps and broken four of them), burn out way before their advertised 25,000 hour life span (I've lost count of how many have become too dim to read by, or even worse just stopped working, after just a few months), melt and smoke and die in the fixtures (this happened three times), and take half an hour to warm up enough to see with (again, lost count). There's NO WAY that these things are more "efficient" with their current design flaws. Maybe in 10 years, after the technology has improved.
For now, it's back to the old reliable: the Edison incandescent that lasts our family an average of two years, doesn't cause toxic environmental contamination or require special cleanup procedures if it gets broken, doesn't cost a fortune, and has beautiful color.
My life is warm again. Ahh...
