LED refers to Light Emitting Diode and is a very common term in lighting and decoration. It is basically a semi-conductor lighting device that is primarily utilized as an indicator lamp as well as for lighting purposes. LED light bulbs are extensively used in homes, offices, commercial buildings as well as other establishments as an essential aspect of lighting. Earlier, LED light bulbs mainly comprised low intensity bulbs but now these can be found in visible, ultraviolet and infrared wavelengths, that assure excellent brightness.

LED light bulbs find a huge range of applications in numerous industries, mainly electric and electronics industries. These bulbs are acknowledged by their features such as excellent light emission, ample brightness, sturdiness and compact size. In reality, the compact size of the LED bulbs has allowed the development of new text and video displays and receptors. LED bulbs are applicable as replacements for conventional light sources in aviation lighting, automotive lighting (particularly indicators) and in traffic signals. Such diverse use of these bulbs, along with cost effectiveness and also other attributes, make these bulbs immensely popular on the market.

LED light bulbs are advantageous over other traditional sources of incandescent lights. These bulbs use up much less electricity and remain functional for a bit longer period. A few of the other advantages of these bulbs include improved robustness, more compact size, faster switching and greater reliability. However, these light bulbs need more precise current and heat management compared to other sources of lighting. More superior use of LED bulbs includes use in communication technology, owing to the superb switching rate. Infrared variations of LED bulbs are also utilized in the handheld remote control units of several consumer products like television sets, DVD players as well as other domestic appliances. The longer service period of these light bulbs is because of the fact that these are prone to very limited wear and tear when operated at low currents and optimum temperatures.

LED bulbs are widely appreciated for maintaining consistent light output even during cold temperatures, unlike traditional lighting methods. This attribute makes these bulbs a great replacement in areas like supermarket freezer lighting where these have lasted longer than any other lighting form. Their use in freezers is more prevalent due to the fact that these bulbs are quite power efficient and do not emit heat.

LED bulbs can be found in different colors and are made of a variety of materials. Some of the common shades of these bulbs are blue, purple, violet, red, orange, yellow and green. Importantly, almost all the types of devices using LED bulbs are very safe to use and don't cause any adverse impact on the consumer. Simply speaking, because of their salient features like reliability, vast range of shades, lightweight, coolness of light generated and energy efficiency, these bulbs are extensively employed in numerous digital and electrical gadgets. Efforts are already on to further develop the LED technology and manufacture more efficient and useful light bulbs. These light bulbs have truly been a boon to various industries thus are preferred by renowned companies and even find application in daily usage.
