Environmentally friendly options for replacing light bulbs are usually compact fluorescent lamps (CFLs) or Light Emitting Diode (LED) lamps.
Compact fluorescent lamps
Energy saving lamps are similar to conventional fluorescent lamps, which uses electricity to mercury vapor that is in the glass tube to activate. The actual impact on the atoms of mercury with ultraviolet light (UV), does not make them visible to the naked eye. The photons from ultravioletThe light hit a phosphor coating inside the lamp emitting photons of visible light, light emitted from the tube. Ultraviolet light can cause discoloration in the images or textiles. The mercury in the lamp means that the bulbs to be disposed of properly, such as compact fluorescent burst deposited in landfills, the mercury is released into the soil drainage, contamination of the food chain to the end. Some states, like California, the ban on the disposal ofmercury-containing lamps in the trash. Some state laws require the collection of fluorescent lamps as hazardous waste or recycled properly. Check with the EPA place to ensure proper disposal procedures for your condition, or you can find a recycling center in your area Earth911.
Unlike fluorescent tubes, which are not integrated circuits, compact fluorescent lamps, in general, all the circuitry required at the base of the light from the single device used in a standardBulb light socket. Compact fluorescent lamps in a variety of styles and forms, but often are seen in a tube or spiral. Larger surface area allows more light output in compact fluorescent lamps.
LED Lighting
Solid-state lighting, better known as known LED (Light Emitting Diode) lighting is an integral part of the semiconductor light source that is not a gas pipe as the CFL. Light from an LED is when the current is applied across the semiconductor doped with impuritiescreating half, the "p-side", the other half, the "n-page" forms. The charge carriers (electrons and holes) flow into the pn junction where the two halves to meet, and releases energy in the form of a photon, so light. The color of light emitted depends on the materials forming the pn junction. There is no filament to burn out, and in contrast with energy-saving lamps, LED lamps do not contain toxic mercury, no ultraviolet light.
An emission of light, many elderlyModels of LED lamps have many individual LEDs used in a home, driving many of the new LED lights feature a single high-power LEDs. These LED lamps are much smaller than their counterparts in the CFL, and are offered in the form factors to produce a directed beam of light provided by the use of a lens of glass or plastic, and enclosed behind a frosted diffuser broader lighting .
Summary of benefits
Less expensive powerBill:
Although the cost of the bulbs are more expensive initially, CFL and LED bulbs save money in the long term. Less electricity is used, and the lamps are replaced less frequently. LEDs consume about half the amount of current compact fluorescent lamps, which use the same light output.
Long term:
Execution times of the CFL bulbs typically range from 6,000 hours to 15,000 hours, while the typical lifetime of a bulb is about 1,000 hours. An LED bulb can last50000-60000 hours, which equals about 5 or 6 years (10 times longer than a CFL).
High-quality lighting performance:
Both CFL and LED lamps, now offers a range of color temperatures. Consumers are no longer limited to blue, "cool white" bulbs of the past and can now warmer colored lamps. Inferior quality CFL bulbs, which use a magnetic ballast flicker. Look for an electronic ballast when you buy a CFL. The LEDs are controlled so as not toflicker.
Versatility:
Interior, exterior, home or commercial LED and CFL bulbs can be used in many different types of applications where traditional light bulbs were once used. LED lamps and compact fluorescent lamps can be used in track lighting, table lamps, outdoor lighting, recessed lights and ceiling lights. Both types of lamps are dimmable models for use with a dimmer standards.
Duration:
Because the LED bulbs do not use a filament like incandescent lamps,They are shock resistant and can be used in high vibration.
Summary of disadvantages and limitations
Compact fluorescent lamps:
No spotlight - Because CFLs do not project a focused beam is used as an LED lamp, which are best for lighting the area.
Sensitivity to temperature - energy saving light bulbs are sensitive to heat, their lives will be diminished if the device will not heat properly discharged. CFLs are also affected by the cold. CFL takes much longer to reach full brightness in coldWeather. In extreme situations, can not heat properly.
Warm-up time - LED on immediately, while compact fluorescent lamps take a few minutes to heat and provide maximum brightness.
Hazardous waste - energy saving bulbs contain mercury and must be disposed of properly. The EPA provides the proper disposal site. LEDs contain no mercury.
Cycling often reduces the life - in high traffic areas such as bathrooms at home, where energy saving lamps and out often, theirLife is sinking fast.
CFL bulbs can emit UV light that can not be desirable for some applications - UV.
LED:
High cost - The LED lamps themselves are expensive, but the initial investment is recovered quickly in lower bills.
Heat generation - Some high-power (5 W and higher) can cause significant heat LED lamps. Heat sinks are often made in the same light bulbs and can some LED devices to ensure the necessaryadequate airflow.
LED lights are the right choice for energy efficient lighting because of their different lighting options, and the ease with which the light emission can be layered and controlled when compared to CFL bulbs.
