With that being said, CFL light bulbs are not appropriate for all applications. They provide a longer warm-up time and generally aren't dimmer compatible see our dimmable CFLs if you need a dimmable style. We have popular, standard options such as watt CFL bulbs plus high-lumen CFLs for extreme brightness and styles in a broad selection of bases. While not as energy efficient as LEDs, spiral CFLs are also significantly cheaper, making them the perfect choice for those looking to upgrade from incandescent bulbs without making the jump to LEDs. At BulbAmerica, we carry a wide range of spiral CFL bulbs available in a wide range of colors and wattages.

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 light bulb ; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp. Compared to general-service incandescent lamps giving the same amount of visible light , CFLs use one-fifth to one-third the electric power, and last eight to fifteen times longer. 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. In many countries, governments have banned the disposal of CFLs together with regular garbage. These countries have established special collection systems for CFLs and other hazardous waste. The principle of operation remains the same as in other fluorescent lighting : electrons that are bound to mercury atoms are excited to states where they will radiate ultraviolet light as they return to a lower energy level; this emitted ultraviolet light is converted into visible light as it strikes the fluorescent coating, and into heat when absorbed by other materials such as glass. CFLs radiate a spectral power distribution that is different from that of incandescent lamps. Improved phosphor formulations have improved the perceived color of the light emitted by CFLs, such that some sources rate the best "soft white" CFLs as subjectively similar in color to standard incandescent lamps. The parent to the modern fluorescent lamp was invented in the s by Peter Cooper Hewitt. The first fluorescent light bulb and fixture were displayed to the general public at the New York World's Fair. Hammer , an engineer with General Electric, [7] in response to the oil crisis. This was the first successful screw-in replacement for an incandescent lamp, using new rare earth aluminum lattice phosphors to solve the problem of lumen depreciation that would normally occur quickly in such a thin tube; however, it was not widely adopted, because of its large size, weight over half a kilogram , pronounced 50 Hz flicker and 3-minute warm up time. Volume was an issue in CFL development, since the fluorescent lamps had to fit in the same volume as comparable incandescent lamps. This required the development of new, high-efficacy phosphors that could withstand more power per unit area than the phosphors used in older, larger fluorescent tubes.

Electronic devices operated by infrared remote control can interpret spiral bulb infrared light emitted by CFLs as a signal; this may limit the use of CFLs near televisions, radios, remote controls, or mobile phones, spiral bulb. The study's authors suggest that the ultraviolet exposure could be limited by the use of "double-walled" bulbs manufactured with an additional glass covering surrounding the phosphor-coated layer.

For expert help, call: Are you searching for an alternative to incandescent lighting for your home or business? Then take a look at our compact fluorescent CFL light bulbs. CFL bulbs, or spiral light bulbs are self-ballasted and do not require an external ballast to operate like fluorescent tubes do. CFL light bulbs come in a variety of wattages, sizes, and color temperatures making them a very versatile addition to your overall lighting plan.

New Scientist. No recently views items. Accessed 1 January Cold-cathode CFLs can be dimmed to low levels, making them popular replacements for incandescent bulbs on dimmer circuits. Download as PDF Printable version. This radiation could aggravate symptoms in people who already suffer skin conditions that make them exceptionally sensitive to light. In the United Kingdom , a similar program is run by the Energy Saving Trust to identify lighting products that meet energy conservation and performance guidelines. CFLs have two main components: a magnetic or electronic ballast and a gas-filled tube also called bulb or burner. Archived from the original on February 28, This means that the CFL may not fit well in existing light fixtures. LSD 40, retrieved One of the most important characteristics that changes with different adaptation levels is the just noticeable difference.

Non-integrated CFLs have the ballast permanently installed in the luminaire , and usually only the fluorescent tube is changed at its end of life.

The Fairmont Press. Electronic ballasts contain a small circuit board with a bridge rectifier , a filter capacitor and usually two switching transistors , which are often insulated-gate bipolar transistors. The U. Environmental Protection Agency estimated that if all million CFLs sold in were sent to landfill sites, around 0. Go to Wish List. View as Grid List. Many municipalities are purchasing such machines. Non-integrated CFLs can also be installed to a conventional light fixture using an adapter containing a built-in magnetic ballast. California Energy Commission. Show 12 24 They are best used in light fixtures that stay on for longer periods.
