Mercury is an element found naturally in the environment and emissions are both natural and man made. CFL light bulbs contain 4 milligrams (mg) of mercury, but by comparison, the older home-use thermometers contained 500 mg of mercury!  The majority of mercury released in the U.S. actually comes from coal-fired power plants (51%).

Burning coal to provide electricity creates large mercury emissions we might overlook — but using CFL bulbs helps reduce the draw of electricity, thus creating a WIN-WIN, which we love around here.

Do you wonder about the mercury in these bulbs?

  1. CFLs are a better solution, both economically and environmentally, than incandescent bulbs, which ultimately result in greater mercury exposure than CFLs. While incandescents do not contain mercury, they still contribute to its release into the environment. Because burning coal to generate electricity releases mercury into the air and incandescent bulbs use more electricity over their lifetimes, they are responsible for more energy consumption and ultimately more mercury emissions than CFLs. In comparison to their incandescent counterparts, CFLs emit approximately the same amount of visible light and last 8 to 15 times as long. With a proven packaging configuration and proper disposal, CFLs can be used effectively without releasing harmful mercury vapor.

    If a bulb is broken or burns out, it should be properly cleaned up and recycled—it should not be disposed of in landfills. To reduce the risk for mercury vapor exposure, CFLs and fluorescent lamps should be safely handled, stored and transported to recycling facilities in a package that is proven to effectively contain hazardous mercury vapor.
