	GE Consumer & Industrial Lighting: Ask Us: FAQs - Compact Fluorescent Light Bulbs
		Fluorescent light bulbs (including compact fluorescents) are more energy-efficient than regular bulbs because of the different method they use to produce light.
		The first compact fluorescent bulbs flickered when they were turned on because it took a few seconds for the ballast to produce enough electricity to excite the gas inside the bulb.
		Compact fluorescent light bulbs may generally be used in enclosed fixtures as long as the enclosed fixture is not recessed.

	Fluorescent Lights and Neon Signs
		Since their development in the 1940÷s, fluorescent bulbs have become the lighting fixture of choice in offices, factories, and schools, and they are beginning to be found more widely in homes as well.
		The light from fluorescent light bulbs looks white in most cases, and that white color is a combination (as it is with sunlight) of all of the colors of the visible spectrum.
		In the fluorescent bulb, high-energy ultraviolet light from within the tube is absorbed by the phosphor, which then re-radiates the energy by emitting two or three lower-energy light waves.

	Bruce of Stone Marmot explains compact fluorescent light bulb basics
		Fluorescent bulbs use about one quarter of the electricity of an incandescent bulb with the same light output.
		If a light bulb is used an average of four hours a day, a CFL will save enough in electricity in typically five months to offset the initial purchase price difference compared to an incandescent bulb.
		Many people actually feel most comfortable and perceived the light to be brightest when the color temp is around 4000, which is between incandescents (typically in the low 3000s) and lights advertised as "cool white," "daylight," or "full spectrum," which are closer to 5000 in color temp.

	Fluorescent lamp - Wikipedia, the free encyclopedia
		A fluorescent lamp is a gas-discharge lamp that uses electricity to excite mercury vapor in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light.
		Compact fluorescent light bulbs may have a conventional ballast located in the fixture or they may have ballasts integrated in the bulbs, allowing them to be used in lampholders normally used for incandescent lamps.
		The UV light is absorbed by the bulb's fluorescent coating, which re-radiates the energy at lower frequencies (longer wavelengths: two intense lines of 440nm and 546nm wavelength appear on commercial fluorescent tubes) (see stokes shift) to emit visible light.

	About Fluorescent Light Bulbs - Fluorescent Ballast, Benefits and Usage
		The most modern of lighting designs for business and industry utilize electronic, though there are various tube designs requiring specialized ballasts to accommodate the specific current and voltage levels their usage requires.
		Operation cost takes into account not only the price to purchase the bulb, but the bulb's lifespan (meaning how often it has to be replaced), the labor cost to replace lights, as well as less cooling costs which result from the bulbs running cool rather than hot and throwing off less heat when in operation.
		An electronic fluorescent ballast is key to energy savings for two reasons: first, their rate of operation is more controlled; second, electronic fluorescent ballasts operate at cooler temperatures, compared to magnetic ballasts, and can thus reduce office cooling costs.

	Fact Sheet
		Lighting accounts for about 20% of all electricity use in the country and about 15% of electricity use in our homes.
		The typical household spends about $110 per year on lighting and most of this is wasted on inefficient incandescent light bulbs.
		These bulbs are actually heaters in disguise, converting 90% of the electricity to heat and only about 10% to visible light.

	Lighting
		It is a small fluorescent light bulb that uses at least 2/3 less energy than a traditional incandescent bulb and can be screwed into a regular light socket.
		The UV light hits the white coating inside the fluorescent bulb and the coating changes it into light.
		While all fluorescent bulbs contain a trace amount of mercury, the quantity is so minute that disposal is not regulated by federal standards (established by the EPA, the Environmental Protection Agency).

	Switch to Compact Fluorescent Light Bulbs
		Use compact fluorescent light bulbs to replace ordinary incandescent light bulbs, and you will be taking a significant step toward reducing greenhouse gases and overall fossil fuel use.
		So, if you stall a compact fluorescent light bulb into a lamp on your child’s first birthday, that same light bulb will most likely be casting light on his or her sixth grade homework ten years later.
		Use of compact fluorescent bulbs is very helpful for older people or anyone who has difficulty replacing their light bulbs, especially in hard-to-reach places like in ceilings, stairways, hallways, and outdoors.

	Compact fluorescent lamp - Wikipedia, the free encyclopedia
		A compact fluorescent lamp (CFL), also known as a compact fluorescent light bulb or an energy saving lightbulb, is a type of fluorescent lamp that fits into a standard light bulb socket or plugs into a small lighting fixture.
		Size: CFL light output is roughly proportional to phosphor surface area, and high output CFL bulbs are often larger than their incandescent equivalents.
		Improving efficiency of household lighting is a part the effort to fight global warming.

	How Many Lightbulbs Does it Take to Change the World? One. And You're Looking At It.
		The bulbs come on quickly; their light is bright, white, steady, and silent; and the old U-shaped tubes--they looked like bulbs from a World War II submarine--have mostly been replaced by the swirl.
		In a fluorescent bulb, the glass tube is filled with gas and a tiny dot of mercury.
		The ballast--built into the bulb rather than in a separate fixture, as with traditional fluorescent tubes--hummed and didn't cycle the electricity quickly enough; it had to be made electronic and miniaturized.

	GE Soft White Spiral 13w Compact Fluorescent Light Bulb 16460 Review at Epinions.com
		With the fluorescent bulb, the electricity stimulates the mercury vapor within certain gasses that, in short, produces short-wave ultraviolet light which in turn, causes the phosphor to fluoresce.
		The fluorescent emits a soft glow where the incandescent is much stronger and harder on the eyes.
		The fluorescent, even at 13 watts, is bright enough to use for my reading, crosswords and in the lamp on my nightstand where a soft but bright light is needed.
