	Fluorescent Lamp
		While the phrase fluorescent lamp may not be the appropriate term technically, it is called so because of the fluorescent coating inside the bulb that converts the ultraviolet light created by the bulb into a visible light that is visible to that naked eye.
		The fluorescent lamp was first made commercially available in the 1920’s, the fluorescent lamp is now being used extensively in all the fields of energy applications.
		Fluorescent lamps are good for human health, but in some case these have been found to pose a serious health hazards in women who are pregnant, children, and infants.

	Mini-fluorescent lamp with automatic on/off - Patent 5459373
		Fluorescent lamps of all types are very popular for use in the home or office because of their high operating efficiency as compared to incandescent lamps.
		A typical fluorescent lamp is constructed from a glass tube that contains two electrodes at opposite ends, a coating of powdered phosphor covering the interior of the tube, and small amounts of mercury.
		Starter ST is a convention starter used to initiate the arc between the fluorescent lamp filaments.

	Fluorescent Lamps, Ballasts, and Fixtures
		Fluorescent lamps are a type of gas discharge tube similar to neon signs and mercury or sodium vapor street or yard lights.
		Fluorescent lamps are about 2 to 4 times as efficient as incandescent lamps at producing light at the wavelengths that are useful to humans.
		Lamps with the longest lifetimes typically use the heavier noble gasses as the buffer gas, (Xenon or Krypton instead of Argon) because the sputtering that occurs at the cathode is due to fast ion bombardment from the ionized gasses in the tube.

	Fluorescent Lamp
		Typical fluorescent tube is filled with inert gas and a small amount of mercury that creates vapor.
		While a standard incandescent bulb might last 1000 hours, a fluorescent lamp might last 9000, with 6000 to 7500 hours being average.
		Warmer, more flattering lamps have been around for years, but they generally produce less light, and are more expensive to operate.

		During the war, 20W daylight fluorescent lamps were to light submarines, since it gave of very little heat.
		The 12W green fluorescent lamp was used for landing lights on aircraft carriers, due to its high impact resistance.
		Almost all other fluorescent lamps were delivered to the navy and used as shrouded lamps.

	Fluorescent lamp Summary
		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.
		Fluorescent lamps require a ballast to stabilize the lamp and to provide the initial striking voltage required to start the arc discharge; this increases the cost of fluorescent luminaires, though often one ballast is shared between two or more lamps.
		Lamps are typically identified by a code such as F##T##, where F is for fluorescent, the first number indicates the power in watts (or strangely, length in inches in very long lamps), the T indicates that the shape of the bulb is tubular, and the last number is diameter in eighths of an inch.

	Fluorescent Document
		Fluorescent lamps are a type of gas discharge tube similar to neon signs and mercury or sodium vapor street or yard lights.
		These lamps are marketed as germicidal lamps, and ones in standard fluorescent lamp sizes have part numbers that start with G instead of F. These lamps will work in standard fluorescent lamp fixtures.
		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.

		Most full-size fluorescent lamps are rated to last 20,000 hours when left on for 3 hours every time they are turned on.
		However, you are paying energy costs for the operating time of the lamps, and the most efficient lamp is the one that is not on when it is not needed.

	landrecwaste: Fluorescent Lamp Recycling
		Options for managing lamps include managing them as hazardous waste, managing them under the universal waste rule, or using a type of lamp that is not hazardous.
		The effect of this regulation is that, in Pennsylvania, all fluorescent lamps, if hazardous, must be managed as either a universal waste or manifested as hazardous waste.
		Lamps from households are not subject to these requirements because household waste is excluded from regulation as hazardous waste at 40 CFR 261.4(b)(1) which is incorporated by reference in the PA regulations.

	The Fluorescent Lamp: a plasma you can use
		The resistance of your fluorescent lamp is not fixed, it depends on the current carried: the greater the current, the smaller the resistance.
		The solution is to coat the inside of the tube with a glow-in-the-dark (fluorescent) paint, which absorbs the UV and re-emits its energy as visible light.
		If a fluorescent lamp were not protected by a ballast, it could in principle draw a huge current.

	Fluorescent Lamp and Bulb Recycling (Site not responding. Last check: )
		Fluorescent bulbs last 10 times longer, operate at a cooler temperature, and use less energy while providing the same brightness and color as incandescent bulbs.
		Fluorescent lamps and light bulbs are considered hazardous waste because they contain mercury and other toxic heavy metals.
		Store your fluorescent bulbs that have reached the end of their life span in an area and in a way that will prevent them from breaking, such as in the box the replacement bulbs came in.

	Energy Conservation Program for Consumer Products: Fluorescent Lamp Ballasts Energy Conservation Standards \| Federal ...
		Based on comments and the growing popularity of electronic ballasts with T8 lamps, the Department solicited further comments specifically on the issue of whether market shifts (e.g., from T12 to T8 lamps) should be considered in determining the impact of an energy conservation standard on commercial and industrial consumers, manufacturers and the nation.
		In the fluorescent lamp ballast industry, there is one ``small'' manufacturer who produces both ``affected'' magnetic and electronic ballasts.
		Since only one of the seven manufacturers of fluorescent lamp ballasts is ``small,'' the Department concludes that today's final rule would not affect a ``substantial'' number of ``small'' manufacturers.
