Lighting has been an essential part of human life since ancient times. Without light, there would be no sense of security or safety for people. Throughout history, people have adapted to different sources of lighting to suit their needs. Initially, people used natural light such as sunlight to brighten up their environment. As civilization progressed, people discovered ways to create and store artificial light. Candles, lamps, and oil lamps were the earliest forms of light sources, providing humans with much needed illumination in times of darkness. As technology improves, so have modern sources of lighting. Today, we have the capability to produce both bright and efficient lights that illuminate our living spaces. Common household bulbs can range from compact fluorescent lights to LED (Light-Emitting Diode) technology. LED lighting is quickly becoming the most popular due to its energy-saving properties and long-life span. In addition to providing illumination, lighting also plays a big role in decorating our environment. From accent lighting for wall art to decorative chandeliers, lighting can drastically alter the ambience of any room. For example, a simple dimmable light can completely turn a room from an average, dark environment to one that is alive and inviting. Whether its natural or artificial, lighting is an important commodity that will continue to evolve with time. With improved technologies, lighting will gain better illumination and energy-saving properties, giving us more options to choose from in the future.
