Why Are Led Bulbs Becoming So Popular

In these days the concentration is on developing energy efficient tools which are environment friendly. We can definitely not manage to play havoc with nature. We are already experiencing the unpleasant results of global warming happened by the excessive carbon emissions in the atmosphere. 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. Hence, it is a green alternative for lighting up spaces. A 12v LED light bulb is as powerful as a 40W incandescent bulb but uses just 2W of power. Which means that these kinds of bulbs utilize only five to ten percent of electricity consumed by the traditional bulbs.

In the beginning, LEDs were used only for indicator lights in electronic machines but now they are being used for lighting purposes too. A light emitting diode bulb is composed 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 just these bulbs are energy efficient but in addition to that they last for a longer time. They even have a life of 7 to 10 yrs depending upon their usage. A 12v LED light bulb if used only for 8 hours a day can work for up to 10 years. Though many people get rid of the idea of getting these bulbs due to their high price, they turn out to be an affordable choice for lighting in the long run. They have five times long life than compact fluorescent lamps, which usually last for only 2 years. Additionally, by using these bulbs in your own home, you can minimize your electricity bills by about 15 to 25%. They do not just reduce the cost of lighting however also the cost of air-conditioning. These bulbs do not emit excessive heat as incandescent bulbs do. For this reason, unlike traditional bulbs they do not heat up the room, which eventually reduces the burden on the air-conditioning system.

LED light bulbs are mercury free and for this reason do not harm the surroundings and the health of the residents. Even, they do not flicker. The shocks and vibrations do not easily harm them as they don't have any filament. These are generally 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 depending upon its specifications. You can get LED floodlights, dimmers, bi-pin lights, flashlights, globes, and so on in different colors. LED light bulbs do not require filters for producing lights of different colors. Companies make LED light bulbs that emit light of different colors by using different semiconductor materials. They also score over incandescent bulbs in respect of luminous efficiency. While the efficiency of a LED light bulb is 55 lumens per Watt, that of an incandescent bulb is merely 15 lumens per Watt.

While everybody is aiming to reduce their carbon footprints, such bulbs have come as a boon. The companies are looking for ways to bring down the manufacturing price of these bulbs so that they can be made available to the masses at affordable rates.
