Lighting is the application of lights to purposeful tasks or activities, usually as a means of providing visibility. In terms of interior design, lighting can be used to enhance the look and feel of interior spaces, as well as to provide functional lighting for tasks like reading, cooking, and cleaning. It is also used to create dramatic moods and to highlight certain features of the space. Lighting is achieved by fixtures such as chandeliers, wall sconces, ceiling fixtures, table lamps, and floor lamps, among others. For outdoor lighting, lanterns and floodlights are common. Color is another important factor to consider when selecting lighting. Warm colours such as yellow, orange, and red will create a warmer, softer atmosphere; whereas cool tones like blues and greens can be soothing and provide a calming effect. The intensity of light is also important. Too little light can cause eye strain, while too much can cause glare and discomfort. The intensity of light should also be adjusted according to the size of the space and the activity that is occurring. Finally, proper positioning of lighting fixtures is key. To create a balanced look, fixtures should be evenly distributed throughout the space. The fixtures should also be placed in such a way that shadows are minimized and the light evenly illuminates the desired area. Overall, lighting can drastically affect the look and feel of a space. When chosen wisely, lighting can be used to create a warm, inviting atmosphere that encourages people to stay and linger.
