Here's my question: do those fluorescent bulbs really last longer than the old bulbs? I feel like I'm replacing bulbs about as often as I ever did. Has anyone done studies since more people started using the newer energy-saving bulbs?

I think the article is referring to the newer LED lights shown in the photo above which are still expensive but quickly becoming more affordable. You can buy an equivalent 60W bulb for about $15 if you shop on line. They last for 25,000 hours and use about 9-10 watts. I expect the price to drop down well below $10 in about a year. They are starting to show up everywhere. I have purchased 16 bulbs for my house so far, some that are only 2.5 watts costing about $5 each but have good illumination as outdoor lights. I can leave the lights on all night and use almost no electricity. Hope to replace all my lights by the end of the year. They now have LED lights which are a soft white color, as opposed to the bluish ones, and are much more comfortable to the eyes.
