Fluorescent Lamps

Usually used as indoor lighting; the most common is the tube style, which serves as overhead lighting in offices and businesses. A newer style is the compact globe shape for a variety of home or office use. Average life: 4 years.

Amount of Mercury: From less than 10 milligrams to 50 milligrams per tube, depending on size and model.

Alternative Devices: Fluorescent lamps are an excellent lighting choice because they use up to 50% less energy than other lamps. This reduces the amount of mercury produced at the power plant, where mercury is given off by coal and oil combustion. Thus, even though incandescent bulbs contain no mercury, their inefficient energy use results in more mercury being released to the environment. However, it is essential that fluorescent lamps are disposed of properly, so as not to allow the mercury to enter the environment. The best disposal method is recycling.

A new type of long-life fluorescent lamp has been developed which contains such a small amount of mercury that it is no longer considered a hazardous waste. The typical fluorescent lamp has a lot of "extra" mercury in it because mercury loses its effectiveness over time due to physical and chemical reactions. This new lamp has a buffering system that blocks these physical and chemical reactions so that the lamp contains less than 10 mg of mercury. These lamps should still be recycled.

How to Locate the Device: Fluorescent lamps are located in offices and businesses. The most common style is the long, skinny tube used in overhead indoor lighting. Compact globe styles are also used in homes and offices.

Safe Removal: Caution should be taken to avoid lamp breakage. Breakage may result in mercury released into the environment. Lamp recyclers also generally require that the lamps arrive unbroken. The best way to protect them is putting old lamps into the boxes the new lamps came in or boxes from a lamp recycler. Most bulbs are removed in one of two ways:

  • With some bulbs, the technique to remove them is to push them in one direction against a spring located in the socket and then they can be removed (much like removing AA batteries from devices)
  • Other bulbs can simply be twisted to be removed, similar to incandescent bulbs

The bulbs are very delicate and should be carefully removed and then placed in boxes for disposal. Often, mercury recyclers rent or provide cylindrical cardboard containers for fluorescent bulbs.

Safe Disposal:

  • Store lamps in containers that prevent them from breaking, such as in their original boxes or in boxes supplied by lamp recyclers. Mark the container "Fluorescent Lamps for Recycling".
  • Breakage of these lamps could result in mercury release. If lamps are broken, store them in a sealed container. Any spilled powder should also be picked up and added to the sealed container.

Either:

  • Send or take lamps to a mercury recycler. Discuss proper shipping methods with the recycler.
  • Take advantage of subsidized mercury collection/drop-off services for small businesses if your city, county or state environmental or solid waste program offers them.

Mercury is one of the group of elements known as heavy metals. Many of these (including lead, cadmium, and selenium) are toxic to living things. Mercury too can kill living things, from bacteria to human beings. In particular, it can be converted into an organic form, methylmercury, which is especially toxic. Learn More...
