A light-emitting diode or LED is a kind of crystalline or amorphous solid that has electrical properties and can be acted as a light source through a process called electroluminescence. LED is widely employed in numerous areas ranging from domestic to industries. On top of being a kind of illumination, LEDs are also used as visual indicators in conveying messages as in the case of traffic lights. Furthermore, LEDs are often involved in signal transmission such as data communication between fiber optic cables.
Most people started using LED because they are trying to save the amount of electricity consumption at home or in workplace. By saving energy also means to reduce electricity bills. This is to why LED is more popular than halogen bulbs as they are able to give off stronger beam at a lower cost. Normally, a LED light which is equivalent to a 50-watt halogen bulb will only burn off about six to seven watts. Even though the purchase and installation of LED cost a lot higher than a halogen bulb, it is actually more economically viable in the long run.
Besides, LED is longer lasting than halogen bulbs. A 30 US dollar LED light will last for several years as compared to a three-dollar halogen bulb which at most runs for six months depending on how often it is being used. LED also does not give off as much as heat as compared to halogen bulb, minimising the possibility of a fire hazard when overuse.
Basically, LED comes in three tones – the warm, neutral, or cool, simulating actual lighting. While getting a LED light to replace the old halogen bulb, one needs to ensure several things. First of all, ensure that the LED bulb has the right base fitting and it is able to fit into the existing circuit without interfering other electrical appliances. Examine the sizes of the original bulb, some LED may by of a bigger size than the current bulb.
Next, Identify the wattage of the bulb and rating of the transformer that one is using at the moment. Transformer rating tells us the maximum and minimum loading which signifies how many wattage of LED bulb you should be looking out for. In the case if transformer is required, look out for those that are equal or above the sum of the wattage rating of all the lights on the same circuit.
Last but not least, it is possible to have LED and halogen bulbs within the same light structure (i.e., chandelier) as long as the overall wattage does not exceed the maximum load in which the product can carry. Old halogen bulbs do contain a certain amount of mercury; thus it is recommended to dispose them back to the retailer or at other proper outlets.
LED is getting more and more popular so if you not in the line, probably you can give it a short today.
