- Compact Fluorescent Lighting - How Much Mercury? (EarthTalk.org)
"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)."
"For environmentalists, the clincher is that by requiring less energy, CFLs will actually cut down on mercury pollution produced by coal burning, and EPA agrees."
"If recycling is not possible, used CFLs should be sealed inside a plastic bag and taken to a household hazardous waste disposal site, just as should batteries, oil-based paint, and motor oil, EPA recommends."
"Web sites such as Earth 911 and Light Recycle can provide local disposal options." 12-07

"If every U.S. household replaced just one standard 60 watt bulb with a CC Vivid LED bulb, we could save 24,184,400,000 watts or 24,184.4 mega (million) watts per day." 11-07

LED bulbs are mercury-free, unlike fluorescent lights, and last up to 50,000 hours compared to 1,000 hours for an incandescent bulb. Bulbs cost around $25 each. Visitors sometimes misspell as flourescent, flourecent, or flouresent. 12-02
- Mercury and Flourescent Bulbs (theBostonChannel.com)
"Consumers were cautioned to avoid using the energy-saving bulbs on tables or in other places where they can be easily broken. Even so, the reports said, the bulbs, which use 75 percent less energy and last 10 times longer than incandescent bulbs, are still the best way for homeowners to try to save on electricity, adding that the benefits of using them outweigh the risks." 02-08

- Compact Fluorescent Natural Lighting (FullSpectrumSolutions.com)
Provides compact fluorescent lights that offer "full spectrum" or "natural" light. The cost is $17 each for 26 watt bulbs (100w equivalent), $26 for 55w bulbs (250w equivalent), and $29 for 65w bulbs (300w equivalent). Explains why full spectrum lighting is desirable. "Independent meter readings of natural sunlight were taken on a sunny day in Michigan on April 19th, 2005 at approximately 4:09pm. The sunlight readings were then compared to measurements of light emitted indoors from the BlueMax Desk Lamp (away from any sunlight) for comparison. The meter readings in the photographs below show that sunlight and BlueMax™ are essentially identical." 6-05

- Compact Fluorescent Natural Lighting Explained (FullSpectrumSolutions.com)
"High CRI of 96 and correlated color temperature of 5900 kelvin makes objects appear as they are supposed to be seen." CRI is "A measurement of the amount of color shift that objects undergo when lighted by a light source as compared with the color of those same objects when seen under a reference light source of comparable color temperature. CRI values generally range from 0(worst) to 100(best)."
Kelvin or color temperature is "A measure of the color of a light source relative to a black body at a particular temperature expressed in degrees Kelvin (K). Incandescent lights have a low color temperature (approximately 2800K) and have a red-yellowish tone; daylight has a high color temperature (approximately 6000K) and appears bluish (the most popular fluorescent light, Cool White, ia rated at 4100K). Today, the phosphors used in fluorescent lamps can be blended to provide any desired color temperature in the range from 2800K to 6000K." 6-05
