The CFL (compact fluorescent lamp), created in response to the 1973 oil crisis is commonly known as fluorescent lighting. It is a more efficient application of electricity. Over the years the technology has improved. CFL’s come in a variety of choices fix most household fixtures. They aren’t recommended for motion activated lighting or those with dimming features. The expectant lifespan diminishes by 85% with frequent ‘flicks of the switch’. The light they radiate emits 72 lumens (a measurement of light as seen by the naked eye) per watt verses the 17 lumens per watt of the more common household bulb.
The Conversion of electricity to radiant energy is 21% more effective. It is estimated they use 20-33% less power to run. The life expectancy is 8-15 times greater, with a rated life span of 15000 hours compared to the 1000 hours of the standard bulbs. The cost (average 10 x higher) per bulb is offset by the efficiency. It is estimated that if every household used just one CFL the energy saved would light 3 million homes. It is comparable to eliminating emissions from 800,000 – 1 million cars each year.
They are good at saving electricity but there are hazards too. Namely the gases used. Argon is a colorless, odorless, tasteless and non-toxic gas. It is found naturally in the air we breathe. In confined areas it can cause asphyxiation. It is heavier and dis-places oxygen.
Each bulb contains up to 4 milligrams of mercury. Mercury is a liquefied and extremely toxic metal. It can be absorbed through the skin, the mucus membranes and the lungs. Exposure to Mercury is associated with nervous system disorders and can lead to psychosis in long-term concentrated amounts.
To reduce the effects of mercury on the environment, it is recommended that burned-out bulbs be recycled. To lower the chance of exposure, put the bulb inside of 2 plastic bags before disposing of it.
If a bulb is broken, immediately turn off any heating or cooling units. Open exterior windows and doors to the room. Wait for 15 or more minutes. Wear disposable gloves. Use a damp disposable towel to pick up the shards of glass. Use a strip of duct tape or packing tape to collect the smaller pieces. Place all of the contaminated items, including the towel, gloves and tape, into a glass jar fitted with a metal lid. A sealed plastic bag, like a large zip-lock can be used as well.
If the contamination occurs on carpet, follow the same guidelines, except after vacuuming, the bag needs to be removed and put into sealed plastic prior to proper disposal. Do this the next few times you vacuum.
Properly dispose of all clothing or bedding that has come directly in contact with the broken CFL. Do not place the items in a washing machine. Always wash your hand after handling contaminated items.
Check with your local agencies to find a recycling center near you.
