Lighting is a very important part of our lives. We turn on the lights when it's dark outside; we provide light to read books; and lighting can even create a special atmosphere in a room. Since the invention of electricity, the ways we produce light have changed drastically. Before electricity, our light sources mainly came from flames. Such families, or businesses would have to rely on firewood, oil, and candles for light. As an alternative, some of them may opt for oil lamps or lanterns, which offered more light with less risk of fire. Today, electricity is one of the main sources for lighting. There are many options available that bring energy savings and improved lighting quality into our lives. For general lighting applications, LED lights are increasingly popular due to their low power consumption and long life. They can be found in many home, office, and commercial settings. Other technologies, such as Compact Fluorescent Light (CFL), are also becoming more and more widespread. High quality LED lighting is also being used to create special atmospheres in commercial and residential settings. Color-changing and dimmable lights can be used to bring a whole new level of atmosphere to a room. Lighting has always been essential to human life, and now with the advent of new technologies and lighting options, it is easier than ever to create the right lighting for whatever situation we want to create.
