subject: The Reason Why Led Bulbs Are Becoming So Popular [print this page] Nowadays the focus is on developing energy efficient devices which are environment friendly. We can definitely no longer manage to play wrong with nature. We are already experiencing the bad effects of global warming caused by the excessive carbon emissions in the environment. Keeping this in mind, LED light bulbs have been introduced and they are soon substituting incandescent bulbs and compact fluorescent bulbs (CFLs). LED light bulbs use only a fraction of the energy used by the incandescent and compact fluorescent bulbs. Therefore, it is a green option for lighting areas. A 12v LED light bulb is as powerful as a 40W incandescent bulb however uses just 2W of power. Which means that these types of bulbs use only five to ten percent of electricity used by the standard bulbs.
In the beginning, LEDs were used only for indicator lights in electronic machines but now they're being utilized for lighting purposes too. A light providing diode bulb consists of a few LED light bulbs clustered together. They emit light in ultraviolet, visible, and infrared wavelength. The color of the light is based on the doping material of the semiconductor.
Not only these bulbs are energy efficient however in addition to that they last for a longer time. They have a life of 7 to 10 yrs depending upon their usage. A 12v LED light bulb if used merely for 8 hours daily can work for up to 10 years. Even though many people ditch the idea of purchasing these bulbs due to their high cost, they turn out to be an inexpensive choice for lighting in the long run. They actually have 5 times longer life than compact fluorescent lamps, that last for only 2 years. Moreover, by using these bulbs in your own home, you can reduce your electricity bills by about 15 to 25%. They do not merely reduce the cost of lighting but also the cost of air-conditioning. All these bulbs do not release excessive heat as incandescent bulbs do. For this reason, unlike traditional bulbs they do not heat up the room, which in the long run lessens the burden on the air conditioning system.
LED light bulbs are mercury free and therefore do not harm the surroundings and the health of the residents. Even, they do not flicker. The shocks and vibrations do not easily damage them as they don't have any filament. They are available in a wide selection of wattages. The most largely used ones are the 12v LED light bulbs that give illumination equivalent to a 40 or 60 Watt incandescent bulb based upon its specifications. You can get LED floodlights, dimmers, bi-pin lights, flashlights, globes, and many more in different colors. LED light bulbs do not need filters for producing lights of different colors. Companies manufacture LED light bulbs that emit light of different colors by using various semiconductor materials. Additionally they score over incandescent bulbs in respect of luminous efficiency. While the efficiency of a LED light bulb is 55 lumens for each Watt, that of an incandescent bulb is only 15 lumens per Watt.
When everybody is aiming to reduce their carbon footprints, such bulbs have come as a boon. The companies are finding ways to reduce the manufacturing cost of these bulbs so that they can be made available to the masses at affordable costs.
