Edison is said to have acknowledged that this was tedious and very demanding work, particularly on those he employed to help him. Having done its work for over 100 years, the bulb, as invented by Edison, is gradually being replaced by a light emitting diode (LED).
While LED lighting has been around for some years now, many questions about it still exist. Is it worth changing to LED lights? Are LED lights more expensive? Do they truly last as long as they are said to? Will they save energy? Do they increase the amount of heat in a room? Will they one day completely replace the traditional light bulbs we have known for over a century? In this article, we took some time to answer the most common questions about LED lighting. We start by defining what it is and its technical details, how it differs from other sources of light, how LED light works, and the categories into which it falls. We then look at the cost and efficiency of LED lighting and its advantages and disadvantages. Finally, we look at what the future of LED looks like...
