Compact Flourescent Lamp and the Environment
Technological advances have come a long way since the incandescent light bulb. Today, the compact fluorescent lamp (CFL) is the most energy efficient light bulb on the market. In the beginning, consumers had resistance toward the CFL. With governmental support in establishing energy-efficient lighting programs, the CFL have been able to stay in the market and improve throughout the years.
With the advances in technology today, we are able to produce a variety of energy-efficient products, one of which is the compact fluorescent lamp (CFL). Having come a long way from the energy-absorbing incandescents, CFL is clearly the choice for the future. CFLs…show more content… (Rigdon and Wadman, 1992). One must wonder why this new and improved technology is left in the dark and why the resistance to the CFL?
The incandescent light bulbs dates back to Thomas Edison’s 1879 design which was a marvelous invention for the 19th Century. The incandescent light bulb heats a filament by electric resistance inside a sealed glass globe and makes the thin tungsten wire glow white hot (Luoma, 1991). The incandescent blub is very inefficient because only 10% of the electricity flowing into the filament becomes light and the remaining nine-tenths is lost at heat (Luoma, 1991). A standard blub is hot to the touch because it expends more than 90% of the electrical energy keeping its tungsten filament hot enough to glow (Roodman, 1993).
A more advanced alternative to the standard incandescent light bulb is the CFL. Fluorescent tubes, developed in the 1930’s, utilize a chemical-physical process involving the ionization of argon gas (Luoma, 1991). The fluorescent bulbs use one-fifth to one-third as much electricity to deliver the same number of lumens as conventional incandescent light bulbs (Petrowski, 1995). However, fluorescent’s adaptability to everyday household lamps have been hampered by the bulkiness of its long tubes and by problems with flickering and unpleasant light. With
