Energy Efficiency of LED Bulbs

June 01, 2012 | Comments: 0 | Views: 197

LED lamps have been in use for the past two decades, owing to their energy efficient technology and longevity. They have been widely used as indicator lights fixed on sockets because of their faint glow and minimal power consumption. However, they have made a mark in the bulb industry for their energy saving property. The following paragraphs discuss the advantages of LED bulbs in terms of energy efficiency and long-term cost-effectiveness.

In the early stages of its invention, LED (Light Emitting Diode) technology had restricted applications because of the limited illumination levels. However, the technology has evolved dramatically, enabling the manufacture of high-powered LED lamps that produce light levels equal to incandescent light bulbs of various sizes. Advancements in technology have also allowed for diverse sizes of LED lamps, allowing for proportional similarity with traditional bulbs. Though they have made a successful debut in the energy-saving bulb market, their costs remain considerably high. However, their long-term performance and energy-conserving capacity outweigh the cost factor. For instance, a 3W LED bulb will give the same lumens level as a conventional 25W incandescent bulb. Therefore, it renders a huge saving in electricity bills. Additionally, LED lamps last longer than incandescent light bulbs.

Advancements in LED technology have given rise to LED bulbs that can fit in existing sockets and lamps. Therefore, it is a good idea to upgrade the existing bulbs in a home to newer energy-efficient LED bulbs. These bulbs are also becoming a sought-after option for commercial lighting because of their higher quality of illumination, better brightness, improved definition and lesser energy consumption when compared to their incandescent equivalents. They are also advantageous over energy-efficient CFL bulbs in terms of safety and environmental friendliness. This is because LED bulbs do not contain mercury as in CFL bulbs, which can lead to hazardous cleanup process if they break. Further, LED technology does not involve heat generation, which makes it safer to handle even when the bulbs areon. The cool operation allows them to last longer as well. High quality LED bulbs have a life expectancy of about 40,000 hours. Wholesale packs provide an economical solution to meet the lighting needs of the entire home. Most of these packs contain bulbs that can be fixed into existing sockets without installing new hardware. New homes have sockets that are especially designed for various types of LED lights.

LED bulbs are considered the next generation lighting solutions as they provide environment-friendly illuminations and economical retrofitting solutions for existing buildings. In addition to providing long-term savings in energy bills, they provide better visibility and reduce maintenance needs. The commonly used 12V LED bulb is as good as a 40V incandescent bulb, yet consumes only 2 watts of power. LED light bulbs use different semiconductor materials,instead of filters to produce differently colored lights. When it comes to energy efficiency, they provide 55 lumens per watt, against the incandescent bulbs that provide 15 lumens per watt. LED bulbs are a boon for people who are trying to decrease their carbon footprints. Manufacturers are looking for means to bring down the cost of these bulbs and make them affordable to all.
