In the News Yes, actually. The old-school, inefficient, heat-generating incandescent bulbs are all but history, CFL (compact florescent) bulbs taking the pedestal what with how relatively inexpensive and efficient they are when it comes to both electricity consumption and overhead cost. However, even these may have a short-lived supremacy as British scientists developed a new way of "growing" the material needed for LEDs on silicon instead of sapphire wafers, which was the original and somewhat expensive way of doing it. Because of this, household-grade lights of LED nature can be produced for under $5.00 and last up to sixty years. LEDs are three times more efficient than CFLs, last substantially longer, and contain no mercury, so they're even more environmentally friendly. These wonder-bulbs are supposed to be available to consumers within two years. It is estimated that if these new bulbs were to be installed in every home and office, it would cut electricity used on lighting by 75%. I'll take twenty of those, please.

You seem to be misinformed about CFL's, TechGeek.

"There's a lot of misleading information out there," said Joel Hogue, president of Elemental Services and Consulting, an Ohio-based company specializing in the cleanup of sites contaminated with mercury. "But when people learn the facts, the level of hysteria dies down."

Like with many other household products, Hogue said, the use of CFLs requires some commonsense precautions. But if a bulb breaks, his company's clean-up services are not required.

"There's an extremely small amount of mercury in those bulbs," Hogue said. "It's a very minimal risk" and can easily be cleaned up at home.

One CFL contains a hundred times less mercury than is found in a single dental amalgam filling or old-style glass thermometer, according to the U.S. Environmental Protection Agency (EPA).

A compact fluorescent bulb can produce the same amount of light for less than quarter of the energy and last eight to ten times as long. A switch to CFLs would save an average household about 50 U.S. dollars a year in electricity bills, according to government estimates.
