Save The Enviorment?
Answer:
A compact fluorescent lamp (CFL), also known as a compact fluorescent light bulb or an energy saving lightbulb, is a type of lamp (light bulb) designed to fit into roughly the same space as an incandescent lamp, but with the advantages of a fluorescent lamp. Many CFLs can directly replace an existing incandescent lamp.
Compared to incandescent lamps of the same luminous flux, CFLs have a longer rated life and use less energy. A CFL can save over US$30 in electricity costs over the lamp’s lifetime compared to an incandescent lamp.[2] However, the initial purchase price of a CFL is often significantly higher than an incandescent lamp of the same output (but this cost is quickly recouped in energy savings assuming average bulb use).
Although CFLs do radiate a different spectrum of light than incandescent lamps,[3] recent technological advances have reduced that difference dramatically. The light emitted by "soft white" CFL's available today are, for practical purposes, indistinguishable from standard bulbs.[4]
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. This light then causes a phosphor to fluoresce, producing visible light.
Unlike incandescent lamps, fluorescent lamps always require a ballast to regulate the flow of power through the lamp. In common tube fixtures (typically 4 ft (120 cm) or 8 ft (240 cm) in length), the ballast is enclosed in the fixture. 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.
It's a lightbulb that uses less energy, but puts out the same amount of light. Oh yeah, and it gives off really harsh, blue-ish light, and I hate them. But "Save the Environment" has nothing to do with it. CFL's don't save the environment, which, by the way, doesn't need saving.
It is a lamp consisting of a tube coated on the inside with a fluorescent material; mercury vapor in the tube emits ultraviolet radiation that is converted to visible radiation by the fluorescent material
If a fluorescent bulb is broken mercury is disbursed into the air so if this happens indoors.you are advised to open a window and leave the room for 15 min. then discard the material safeguarding your skin from coming in contact with any part of the broken bulb
To me this seems to be good in one respect yet extremely HAZARDOUS in another..
