	Household Lighting
		To produce light in the visible range, the inside of the tube is coated with a phosphor powder.
		In the case of the fluorescent lights, a carefully selected and blended set of phosphors is used so that the wavelengths at which it fluoresces are distributed evenly over the visible range.
		Fluorescent lights are much more efficient light sources than incandescent bulbs, but they are harder to control.

	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.
		Compact fluorescent light bulbs may generally be used in enclosed fixtures as long as the enclosed fixture is not recessed.
		Most light sources, including fluorescent bulbs, emit a small amount of UV, but the UV produced by fluorescent light bulbs is far less than the amount produced by natural daylight.

	Light - why fluorescent?
		Fluorescent lamps are energy efficient, cost effective alternative lighting sources with many benefits to you, the user, and the environment.
		Fluorescent lamps are 8 times more efficient, using only 25% of the electricity required by an incandescent lamp to produce the same amount of light.
		If the light is too bright or too dim, if the contrast of the task is too high, or if there is too much glare, the eye becomes overworked as it struggles to compensate for the environment.

	How Things Work - Fluorescent Lamps
		Light in such a lamp is created by an electric arc--electricity is passing through a gas in the lamp and causing violent collisions within the gas.
		The spectrum of light from a fluorescent lamp is not simple or featureless--many wavelengths are essentially missing and the intensities of the remaining wavelengths don't vary smoothly with wavelength.
		Light that falls in between those wavelength ranges stimulate the three groups of cells to various extents and our brains use their relative stimulations to assign a color to the light we're seeing.

	Fluorescent lamp - Wikipedia, the free encyclopedia
		The earliest ancestor of the fluorescent lamp is probably the device by Heinrich Geissler who, in 1856, obtained a bluish glow from a gas which was sealed in a tube and excited with an induction coil.
		The inner surface of the bulb is coated with a fluorescent (and often slightly phosphorescent) coating made of varying blends of metallic and rare-earth phosphor salts.
		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.

	Wayne Schmidts Fluorescent Plant Lighing Page
		Light at this frequency is yellow-green and is the color to which our eyes have adapted for maximum sensitivity.
		This is gives an advantage to artificial lighting because it enables the spectrum of the light source to be tailored to match the plant's requirements without wasting a lot of power generating light at frequencies that the plant can't use.
		The light from a point source like a normal incandescent bulb falls off by the square of the distance: doubling the distance from the bulb reduces the intensity by a factor of four.

	Fluorescent Light Principles
		Whereas the incandescent system relies on light emission from thermal characteristics, the fluorescent system operates through the principles of electron flow and photo-phosphorescence.
		A fluorescent tube is constructed in its most simple form with a filament similar to an incandescent light bulb at either end, and a coating of a phosphorescent material on the inside of the glass envelope.
		Characteristics and properties of pertinent lighting devices may be found in the Fluorescent Tubes section.

	FAQs: Fluorescent: GE Commercial Lighting Products
		The combination of gas, electricity, and coating in a fluorescent bulb is so effective at producing light that, without something to regulate the electricity flowing into the bulb, the light will continue to gain intensity until the bulb stops working.
		It cites a study in which it was determined that UV exposure from sitting indoors under fluorescent lights at typical office light levels for an eight-hour workday is equivalent to just over a minute of exposure to the sun in Washington, D.C. on a clear day in July.
		Blacklight lamps emit light in the 350-400 nanometer region of the spectrum.

	Fluorescent Light Tube Recycling
		Fluorescent light tubes are used to provide illumination in numerous facilities on the University of Michigan (U-M) campus.
		All spent fluorescent light tubes replaced during preventative maintenance and renovation activities are sent to a recycling contractor for processing.
		Spent fluorescent light tubes are removed from fluorescent light fixtures and packaged in cardboard boxes specifically designed for individual tube types to prevent breakage.

	Fluorescent Lighting - FIM 282 - NCSA School of Film
		You cannot use different types of lighting (such as tungsten fixtures and fluorescent fixtures) of differing color temperatures to simultaneously light the same frame and expect the lab to be able to correct for ALL of them at once.
		Correcting fluorescent lighting in the lab has an apparent build up of print contrast and is never a total correction.
		Because you need the entire frame to have one overall color balance, all the lights at your location, as well as the units you bring to light with, should be made to color match one another as closely as possible.

	Compact Fluorescent Light Bulbs
		But fluorescents have not been popular with homeowners, who found they had too many disadvantages: they needed their own, extra large fixtures, they were too noisy, they often flickered annoyingly, they were oddly colored, and they took several seconds to light.
		Compact fluorescents in the 9 watt, 18 watt, and 25 watt sizes provide approximately the same amount of light as 40 watt, 75 watt, and 100 watt incandescent bulbs.
		Another disadvantage is that the compact fluorescent bulbs run somewhat dim in cold weather, so they may be unsuitable for use in outdoor lights or in unheated garages or other spaces.

		Fluorescent lamps are a type of gas discharge tube similar to neon signs and mercury or sodium vapor street or yard lights.
		For fluorescent fixtures using rapid start or instant start ballasts, it is often necessary for the metal reflector to be connected to the electrical system's safety ground.
		Why fluorescent lamps may not be as bright as you thought?: ----------------------------------------------------------- "I recently replaced a kitchen overhead fixture with two 75 watt bulbs with a fluorescent one having two 20 W bulbs.

	Howstuffworks "What is the difference between a fluorescent light and a neon light?"
		A neon light is the sort of light you see used in advertising signs.
		A fluorescent light, on the other hand, is most often a long, straight tube that produces white light.
		The light we see from a fluorescent tube is the light given off by the phosphor that coats the inside of the tube (the phosphor fluoresces when energized, hence the name).

	EPA Region 10 - PCBs in Fluorescent Light Fixtures
		Light ballasts are the primary electric components of fluorescent light fixtures and are generally located within the fixture under a metal cover plate.
		Fluorescent lamps/tubes should be changed in pairs; new lamps should not be used with old lamps.
		Before EPA banned the manufacture of PCBs in 1978, PCBs were commonly incorporated in the manufacture of fluorescent light ballasts.

	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 screws 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.

	Compact Fluorescent Light Bulbs : ENERGY STAR
		If every American home replaced just one light bulb with an ENERGY STAR, we would save enough energy to light more than 2.5 million homes for a year and prevent greenhouse gases equivalent to the emissions of nearly 800,000 cars.
		To get the most energy savings, replace bulbs where lights are on the most, such as your family and living room, kitchen, dining room, and porch.
		To get a CFL with the right amount of light, choose one that offers the same lumen rating as the light you are replacing.
