Legislation going into effect starting this year is pushing all of us into the brave new world of Light-Emitting Diode (LEDs) and Compact fluorescent lightbulbs (CFLs). According to the 2007 Energy Independence and Security Act, most screw-in light bulbs must use at least 27 percent less energy by 2014. Here’s the timetable for phasing out the old-school incandescent bulbs that Americans have used for 100 years:
- 2012: As of January 1, 2012, 100-watt bulbs are no longer being made or imported, but they can be sold until supplies run out
- 2013: The 75-watt incandescent bulb can no longer be made or imported
- 2014: 60- and 40-watt bulbs get phased out
Why are incandescent bulbs going away?
When you look at the energy used by the 3 billion incandescent bulbs currently in use, less than 10 percent produces light; the rest creates heat. That’s a lot of wasted electricity. Here’s a quote from the EnergyStar program:
If every American home replaced just one light bulb with a light bulb that’s earned the ENERGY STAR, we would save enough energy to light 3 million homes for a year, save about $600 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to those from about 800,000 cars.
I don’t like the light quality of the new bulbs.
The latest LED bulbs offer several shades of white light, depending on your needs and preferences: warm (the closest to the yellowish light of incandescent bulbs), cool white or daylight, a bluer shade. (See a demo here.) CFLs also come in a complete range of hues, including a warm white light (2,700 to 3,000 Kelvin) that’s identical to the incandescent glow you’re used to (learn more here).
I heard that CFLs are dangerous because they contain mercury.
They do contain a minute amount of mercury, but in much smaller amounts than the original CFLs- risk is very low. Read the EPA CFL information page to get the facts.
I don’t want to pay the extra money for the new-fangled bulbs.
Compared to the old, inefficient incandescent, there can be a bit of sticker shock with the high-efficient bulbs. But first off, prices have dropped considerably (you can find 60-watt CFLs now for under $2). A typical CFL uses less than 1/4 of the energy of an incandescent bulb of comparable wattage—and lasts 10 times longer. LEDs are more expensive than CFLs, though prices are getting lower all the time. ENERGY STAR-qualified LED bulbs use about the same amount of energy as CFLs and last 20,000 to 50,000 hours. If you use an LED three hours a day, that’s between 18 and 46 years!
