CFLs have been around since 1990 and since then, the quality has improved vastly. They are available in a wide variety of sizes, turn on almost immediately, and are as bright as you need them to be. A 2007 test by Popular Mechanics revealed that people judged the light of CFLs to be better than that of incandescents. You can choose between warm light (yellow) and daylight (blue) bulbs by checking the package.
CFLs save 75 percent of electricity. This is not a small number. The average U.S. household has 45 light bulbs—replacing that number of 75-watt incandescent bulbs with CFLs will save $880 per year, considering Maui’s high electricity costs.
The expected lifetime is seven years; however, there are often bulbs that don’t work right away or burn out fast. If you look for the ENERGY STAR symbol on the packaging, you can select better quality bulbs. Manufacturers producing ENERGY STAR-qualified CFLs are required to offer at least a two-year limited warranty for CFLs used at home.
Mercury has been a big issue for a while. A CFL contains four milligrams of mercury, just enough to cover the tip of a ballpoint pen. Should a bulb break, it is advisable to air the room, wipe it up with cardboard and a wet paper towel, and then wash your hands. Used CFLs can be recycled at Home Depot. But to keep the problem in perspective, you should know that CFLs don’t break as easily as fluorescent tubes, which contain more mercury.
The United States puts 50 tons of mercury into the air by burning coal for electricity. Switching to CFLs reduces mercury emissions by twice of what the bulb contains.
And here is the good news: In 2007, enlightened Americans reduced greenhouse gas emissions by the equivalent of two million cars—just by switching their lightbulbs.
