Compact Fluorescent Lamp Basics Compact fluorescent lamps are an energy-efficient option to common incandescent light bulbs. With compact fluorescents, an integral lamp and ballast unit with screw-in base and capsule type enclosure providing the appearance of an incandescent source.Tubular, globe, or other shaped enclosures may be used. Compact fluorescent lamps are an exception; many are available with screw-in bases for use in standard sockets. www.healthgoods.com /Education/Healthy_Home_Information/Lighting/cfl_basics.htm   (735 words)

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 regular light bulb socket or plugs into a small lighting fixture. Another type of CFL is the electrodeless lamp (sometimes called a radiofluorescent lamp or RFL), which uses radio waves instead of an electric current to ionize the mercury to produce the ultraviolet light used to excite the phosphors. Another variant of the CFL is coated (outside the bulb) with titanium dioxide, which the manufacturer claims reduces odors by ionization and oxidation. en.wikipedia.org /wiki/Compact_fluorescent_lamp   (2271 words)

Compact fluorescent lamp having a helical lamp envelope - Patent 5751104 1, a compact fluorescent lamp 10 constructed in accordance with the teachings of the prior art, includes a lamp envelope configuration 12 with a plurality of extension tubes 12a, 12b, 12c and 12d, each of which extend upward from a housing 14 in a parallel manner to one another. The discharge occurs within the lamp envelope 12 in a standard manner whereby a fill of mercury and a noble gas is excited to a discharge state by introduction of the operating signal generated by the ballast circuit arrangement 20. If one were to utilize the compact fluorescent lamp 10 of the prior art in a lighting fixture designed for downlighting or for a reading light application, it is important to have light radiating from the top of the lamp similar to the manner of a conventional A-line incandescent lamp. www.freepatentsonline.com /5751104.html   (3804 words)

Reference.com/Encyclopedia/Compact fluorescent lamp CFLs can also be operated with solar powered street lights, using solar panels located on the top or sides of a pole and luminaires that are specially wired to use the lamps. LED lamps have current efficiencies of 30% with higher levels attainable, and a lifetime of around 50,000 hours, but currently are struggling to deliver the required intensity of light output for domestic uses while maintaining a reasonable working lifespan, at a reasonable cost. CFLs, like all fluorescent lamps (e.g., long tubular lamps common in offices and kitchens), contain small amounts of mercury and it is a concern for landfills and waste incinerators where the mercury from lamps may be released and contribute to air and water pollution. www.reference.com /browse/wiki/Compact_fluorescent_light_bulb   (5686 words)

Compact fluorescent lamp fixture ventilation method and apparatus invention Lamp chamber ventilation is passive and/or active through the use of vents in the lamp chamber and/or the use of a fan to induce air flow. Compact fluorescent lamp fixtures do not run optimally at high temperatures and thus are at a competitive disadvantage to metal halide units and some of the other HID fixtures. CFL fixtures create a significant amount of heat that may be constrained in the lamp chamber, reflector, refractor or dome of the luminaire resulting in the production of less lumen output, than would be optimal or is theoretically available from a given lamp. www.freshpatents.com /Compact-fluorescent-lamp-fixture-ventilation-method-and-apparatus-dt20061019ptan20060232984.php   (1746 words)

Fluorescent lamp at AllExperts Compact fluorescent light bulbs may have a conventional ballast located in the fixture or they may have ballasts integrated in the lamps, allowing them to be used in lampholders normally used for incandescent lamps. 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. en.allexperts.com /e/f/fl/fluorescent_lamp.htm   (4702 words)

UV Lighting for Reptiles: Compact Fluorescent Lamps Because compact lamps may be mounted vertically or horizontally in the vivarium, and they have a complex three-dimensional shape, Spread Charts were constructed in both orientations to obtain a fuller picture of their output. The beam from a compact fluorescent lamp is, roughly speaking, an extension of the shape of the lamp into the air around it, forming a flattened sphere with a UVB gradient increasing sharply as the lamp is approached. Compact fluorescent lamps would appear to be useful in the small vivarium in which there is a requirement for a localised zone of fairly diffuse UV light. www.uvguide.co.uk /compactlamps.htm   (1642 words)

Fluorescent lamp   (Site not responding. Last check: ) Fluorescent lights are more efficient than incandescent lamps because less of the energy is converted to heat. The fluorescent lamp was invented in 1900 by Edmund Germer. Bulbs are typically identified by a code such as F##T## where F is fluorescent the first number indicates the power watts (or strangely length in inches in very long bulbs) the T for tube and the last number is diameter in eighths of an inch. www.freeglossary.com /Fluorescent_lamp   (656 words)

compact fluorescent lamp (CFL) Lamps that combine the energy efficiency of fluorescent lighting with the convenience and popularity of incandescent fixtures. CFLs can replace incandescents that are roughly 3—4 times their wattage, saving up to 75% of the initial lighting energy. CFLs are most cost effective and efficient in areas where lights are on for long periods of time. www.daviddarling.info /encyclopedia/C/AE_compact_fluorescent_lamp.html   (539 words)

Compact Fluorescent Lamps: What You Should Know - NRC-IRC Compact fluorescent (CF) lamps are lamps of choice for those looking for an energy-efficient alternative to incandescent lamps: they are praised for consuming as little as one-fifth of the power and lasting up to 13 times longer than incandescent lamps. The coldest spot on the lamp surface is the temperature that controls the light output of a compact fluorescent lamp. Compact fluorescent lamps have a CRI of 82 (out of 100), which is considered excellent for fluorescent sources and good for artificial light in general. irc.nrc-cnrc.gc.ca /pubs/cp/lig3_e.html   (2878 words)

Compact Fluorescent Lamps: Selecting Compact fluorescent lamps are available with integral reflectors or diffusers to improve light distribution, as shown in Figures 1 and 4. Fluorescent lamps emit light strongly in a few narrow bands of color that are created by the mercury vapor in the lamps. Compact lamps are smaller and they draw less current than conventional fluorescent fixtures, so they have the potential of emitting less electromagnetic radiation. oikos.com /library/eem/cfl/selecting.html   (1578 words)

Compact Fluorescent Lighting Compact fluorescent lamps are a fairly recent innovation, and are primarily targeted for use in residential situations, but it is also common to find them in commercial situations such as hotels and restaurants. The lamp and ballast were usually separate components so that the lamp could be replaced (some lamps also had the starter built into the lamp connector so that the starter would be replaced at the same time as the lamp), but this modular design also added more length and weight to the complete assembly. The compact fluorescent lamp is almost the same size, and when fully illuminated, it produces a brighter light than the 40 watt incandescent lamps did, all for 13 watts or so per compact fluorescent lamp. nemesis.lonestar.org /reference/electricity/fluorescent/compact.html   (4146 words)

Compact Fluorescent Lamps are among the simplest and cheapest solutions available to the average person to reduce greenhouse gas emissions. CFL's are the best solution toward extending the useful life of the earth's fossil fuel reserves, and toward the future of reduced use of energy by replacing high energy using items with more energy efficient products. www.spiceplace.com /compact-fluorescent-13-watt.php   (628 words)

Compact fluorescent lamp 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. CFLs use about 20% of the power, and so in the simplest case when compared with incandescent bulbs, they can be responsible for about an 80% reduction in electricity costs and therefore also in the environmental impact of generating that electricity. CFLs with UVA generating phosphor, are an efficient source of long wave ultraviolet "fllight", much more efficient than incandescent "fllight" bulbs, since the amount of UV light that the filament of the incandescent lamp produces is according to flbody radiation, and the UV radiation is only a fraction of the generated spectrum. www.homestayfinder.com /Dictionary.aspx?q=Compact_fluorescent_lamp   (3789 words)

Compact fluorescent lamp Compact fluorescent lamps have some benefits in comparison with classic light bulbs. Compact fluorescent lamp use vacuum pipe similar to classic strip lamp and princip of energy transformation to light is same. Because there are used switched converter, which works on tens of kilohertz, that CFL lamp doesn't "blink" in comparison to classic strip tube lamp. www.pavouk.org /hw/lamp/en_index.html   (1214 words)

Compact Fluorescent Lamp Basics and Pitfalls Compact fluorescent lamps usually do not produce full light output until they warm up for a minute or two. One not-so- compact "circline" unit designed to fit into table lamps is about as bright as a 100 watt bulb, or slightly brighter, but is claimed to be as bright as a 150 watt bulb. Like other fluorescent lamps, compact fluorescent lamps should only be used where they are left on (on an average) at least 15 minutes, preferably at least a half hour, once they are turned on. members.misty.com /don/cf.html   (804 words)

Energy-Efficient Compact Fluorescent Table Lamp The relationships between the lamps, the septum and the lamp shade have been designed to maximize the efficient distribution of light as well as to provide soft and even shade brightness. The lamp was designed by the same Berkeley Lab research group that developed the compact fluorescent lamp-based alternative to the dangerous and inefficient halogen Lamp features were designed to enhance lighting quality and user visibility particularly in office applications with computer tasks. www.lbl.gov /Science-Articles/Archive/cfl-tablelamp.html   (641 words)

Recessed lights, under-cabinet lamps and picture lights are all examples where the light itself is the eye-catching element, not the source that it comes from. CFL bulbs come is several shapes and sizes, including a unique spiral shape that can disperse light much more evenly than a traditional bulb. www.shopnbc.com /product/?familyid=V34538   (1079 words)

Panasonic 11 Watt Performance Collection Compact Fluorescent Lamp EFS11E27 Review at Epinions.com With some lamps, the ballast may be too broad to fit into the "harp", or the metal frame that comes from the socket, and supports the lamp shade. While an incandescent and a fluorescent bulb may be rated the same number of watts, and make the same amount of light (as measured in lumens), to your eye the fluorescent light may appear dimmer, because of the way the light is emitted. Explained a different way, you may want a fluorescent light a notch or two brighter than the one which is advertised on its package as being "equivalent to" an incandescent light of a certain number of watts. www.epinions.com /content_126639902340   (1198 words)
