THE FUTURE OF CFLs....A couple of years ago I went on a binge and replaced a whole bunch of incandescent bulbs in our house with CFLs. Unfortunately, I discovered that their burnout rate was surprisingly high. Out of 20 bulbs or so, I think I had to replace four or five within 18 months. CFL expert Michael Siminovitch confirms that my experience wasn't just a fluke:
Consumers have an expectation that compact fluorescents will last a very long time significantly longer than the incandescents that they're replacing. This is technically achievable. Compact fluorescents can last a very long time. Unfortunately, I think we've compromised greatly on quality with many compact fluorescents and these things are not lasting quite as long as consumers have been led to believe. This is an issue.
He says that color and dimming issues with CFLs (which I was aware of before I bought mine) can also be addressed, but only with tighter standards and higher prices. If we got serious about it, though, economies of scale would drive down the price of high-quality bulbs fairly quickly. More here.
