Bulb Myths Debunked

A variety of CFL technologies are available today. The bulb shown above is a clear glass prototype of a hybrid halogen-CFL technology, which hides an instantly bright halogen capsule inside the swirl of a CFL bulb, all housed in a traditional-shaped bulb. Courtesy: GE Lighting

(NAPSI)—Here’s a bright idea: It may be time to get with compact fluorescent light bulbs (CFLs). Soon, standard incandescent bulbs are going away as a result of continued demand for more energy-efficient lighting products as well as U.S. federal lighting efficiency standards. This means energy-efficient alternatives such as CFLs are becoming even more commonplace.

Though CFLs save considerable money on electricity bills and light homes with a bright, white light, myths still surround them.


To help, industry-leading experts from GE Lighting are shedding some light on myths and questions, including lighting legislation changes, at www.gelighting.com/2012. Among the myths:

  • Myth: CFLs contain high levels of mercury. GE CFLs contain a very small amount, 2 milligrams on average, which is smaller than a ballpoint pen tip. By comparison, older home thermometers contain 500 milligrams of mercury. It would take literally hundreds of CFLs to equal those amounts.
  • Myth: If I break a bulb, I need to see a doctor. Scientists employed by the Environmental Energy Technologies Division at the Lawrence Berkeley National Laboratory found that the amount of mercury a person is exposed to in cleaning up a broken lamp is equivalent to a bite of tuna, and even the worst-case CFL breakage scenario measured by one state EPA was equivalent to eating just a single meal of albacore tuna.
  • Myth: CFLs are too expensive. CFL costs have decreased significantly in recent years. Some cost less than $2 when part of a multipack.
  • Myth: CFLs produce an unattractive blue light. Today’s CFLs can produce a soft, white light in color ranges similar to incandescents. Look for Kelvin numbers on packaging. Bulbs with a 2,700 to 3,000 Kelvin (K) number emit a warmer, yellower color. Those with a 3,500 K to 6,500 K number emit a bluer or whiter light.
  • Myth: CFLs give people headaches. Anecdotal reports of headaches are very rare, and there is currently no scientific evidence that CFLs cause headaches. While older, long-tube fluorescent bulbs in industrial settings could have caused headaches due to their noticeable flicker rate, today’s CFLs operate at a faster frequency to eliminate flickering.

    Yeah, I’m sure that one bulb’s mercury content won’t pose a grave danger in your home, however I would assume (As an American), most American’s are too lazy to properly dispose of CFL’s when they no longer function. these bulbs end up in landfills and contaminate the water supplies nearby and the wildlife. LED’s are the best and most modern lighting. They are relatively inexpensive now and when I buy mine from EarthLED I have a 3 year warranty on my lights, so I feel better about spending the extra money on longer lasting and warranty backed products.
