What are the pros and cons of compact fluorescent light bulbs?
Compact fluorescent light bulbs (CFLs) are poised to replace those familiar incandescent bulbs we’ve been using since electricity became a household necessity. Among their benefits: • CFLs use 90 percent less energy than incandescent bulbs. • They emit very little heat. Unlike CFLs, incandescents waste energy because they spend 90 percent of their energy on heat and only 10 percent on light. That also adds heat to your home’s air and makes your air conditioner work harder. • CFLs last about 10 times longer than incandescents, so you don’t have to change your light bulbs nearly as often. The quality of CFLs continues to improve. Early versions of fluorescent light bulbs were an odd white color, took a long time to light up when you flicked the light switch and gave off a buzzing sound. Today’s CFLs are smaller, come on almost instantly, appear close in color to the traditional incandescent bulb and are silent. A few drawbacks: • Most CFLs are not dimmable.
