Lighting is an essential part of life in the 21st century. Without it, our lives would be much more difficult, as it is used to light up dark and confined spaces, and to provide a source of light during the nighttime or in extreme climactic conditions. Even though it has become an indispensible part of our modern lives, lighting has been used for centuries to create atmosphere in a home, to illuminate a work environment or entertainment space, and for safety and security purposes. Electric lighting, commonly known as artificial lighting, has seen a dramatic rise in use since the early 20th century. This type of lighting is widely used today and includes a variety of different options from incandescent and fluorescent bulbs to LED and halogen lights. It is an affordable and versatile choice in many circumstances, and allows users to control the intensity of the lighting. Natural lighting, or daylight, is also used to light many indoor and outdoor spaces. This type of lighting requires minimal effort to achieve and can be a very affordable option. It is most common in houses, decks and patios with glass windows or skylights, as it does not need to be used as often as artificial lighting. Natural lighting also brings in natural warmth and can create a more comfortable atmosphere. Lighting, whether it be electric or natural, can affect our lives in various ways. It can influence our mood, help to create a positive or relaxing atmosphere, and allows for tasks to be accomplished when it is dark outside. Choosing the best lighting option for a particular space will depend on the purpose and how much light is needed. Some people may prefer to have one type of lighting over the other, and may also mix various types of lighting to create the desired atmosphere for their home or workplace.
