Lighting is something that has been around since the beginning of time. The sun, the moon, and even fire can be thought of as one of the oldest forms of lighting. Through the years, people have used various sources of lighting to help them get around. Today, the use of lighting is much more sophisticated and efficient. Different types of lighting may be used for different purposes. For instance, incandescent bulbs are often used for general lighting in homes and businesses. LED lighting is often used for task and accent lighting. Fluorescent lighting is popular for fluorescent tubes and are often found in commercial and industrial settings. Different lighting techniques are often used to help create specific effects. Indirect lighting and up lighting are often used in areas such as lobbies and desks as it adds a pleasant atmosphere. Downlighting is often used to create dramatic shadows and focus attention to architectural elements. Interesting lighting fixtures, such as wall sconces and chandeliers, can add visual interest to a room. In addition to aesthetics, lighting plays an important role in safety. Proper lighting in a stairwell or hallway can help provide enough illumination for people to safely navigate the space. Outdoor lighting can be used as a deterrent to crime and increase the feeling of safety in public spaces. Lighting can be used to enhance the atmosphere in any room. With its wide array of uses, it is no wonder that lighting has become such an important part of our lives.
