Lighting is extremely important in any living environment. It can affect how comfortable and relaxed, or energetic a person feels. Lighting is also an element of design. It can be used to create an environment that conveys a certain style and serves a function. The type of lighting chosen for a home or business can be determined by the purpose of that space. Natural lighting, such as sunlight, is an important source of light in most spaces. It is free and abundant, and it provides a sense of connection to the outdoors. Artificial lighting is also necessary in most spaces, whether that be to provide illumination in dark areas or to set a certain atmosphere. In residential spaces, accent lighting, overhead lighting, task lighting and natural lighting are all essential. Accent lighting is used to highlight and bring focus to certain elements such as artwork or architecture. Overhead lighting is often installed in the form of ceiling lights, pendant lights or chandeliers to provide general light to the room and to brighten up darker areas. Task lighting, such as desk lamps, are used to provide direct light for activities such as reading or cooking. In commercial environments, lighting can be used to export the brand identity, create a welcoming atmosphere or provide task-oriented illumination. Its important to choose lighting that is appropriate for the size and layout of the space. LEDs or halogen lights are often used in commercial spaces because of their energy efficiency and long life. No matter what type of lighting is chosen, a combination of light sources can be used to create an overall effect in any space. Lighting is an essential tool for creating a desired atmosphere and providing illumination for everyday activities. It is an integral part of any living space and can often make the difference between a drab and uninviting space and a warm, inviting one.
