CFL bulbs are made of glass tubes filled with gas and a small amount of mercury.
A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to glow. A fluorescent lamp tube is filled with a gas containing low pressure mercury vapor and argon, xenon, neon, or krypton. The pressure inside the lamp is around 0.3% of atmospheric pressure. A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. A CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime. Like all fluorescent lamps, CFLs contain toxic mercury which complicates their disposal. In 2008, the A-shaped CFL bulb was introduced. This bulb is made by fitting a spiral CFL inside a regular light bulb shape, giving it a kind of ship in a bottle look. Globe CFLs feature spiral bulbs tucked inside round bulbs, and are designed for bathroom vanities and ceiling fan lights. How Fluorescent Bulbs Are Made. Compact fluorescent bulbs (CFLs) are made using the same basic technology as the traditional fluorescent bulb, which has been in use for nearly a century. They are made from two main parts, which include a simple glass tube and a electric ballast. The inside of the tube is coated with phosphoru Dimmable CFLs are not a 100% replacement for incandescent fixtures that are dimmed for mood scenes such as wall sconces in a dining area. Below the 20% limit, the lamp may remain at 20% or flicker or the starter circuitry may stop and restart. Above 80%, the bulb may operate at 100%. A CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime. Like all fluorescent lamps, CFLs contain toxic mercury which complicates their disposal. CFL benefits. CFLs are four times more efficient and last up to 10 times longer than incandescent light bulbs. A 22 watt CFL has about the same light output as a 100 watt incandescent. Compact fluorescent light bulbs use 50 - 80% less energy than incandescent light bulbs. CFL light bulbs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets, and give off light that looks just like the common incandescent bulbs-not like the fluorescent lighting we associate with factories and schools. Netlore Archive: Forwarded email claims CFL light bulbs made in China and sold under the brand name Globe pose a serious fire hazard and should be avoided. .

Four inch flames were spewing out of the side of the ballast like a blow torch! I immediately turned off the lights. Text example: Email contributed by an AOL user, Jan. 17, 2011: Subject: CFL light bulbs.  CFL bulbs, on the other hand, are made of glass tubes filled with gas and a small amount of mercury. The amount is so small that an old-fashioned glass thermometer holds 100 times as much mercury as one CFL bulb. The mercury in a CFL bulb also means that you should not toss burned-out bulbs in the trash. Many municipalities offer recycling services, as do retailers such as Home Depot, Wal-Mart and IKEA, although not necessarily at all locations. Electric lighting consumes up to 25% of the average home energy budget. The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of a cfl bulb or compact fluorescent light bulb.

They screw into standard lamp sockets, and give off light that looks just like the common incandescent bulbs-not like the fluorescent lighting we associate with factories and schools.
