Lighting is often taken for granted in our modern world. But, it is now seen as important because it has a role to play in creating the atmosphere in any room. Good lighting can instantly and dramatically change the look of any room. In an office, for example, an appropriate lighting system can help reduce eyestrain, promote concentration, reduce fatigue, and create a relaxed and productive atmosphere. Apart from atmosphere, lighting plays a major role in helping people recognise and identify people and objects. For this reason, it is necessary to choose the right lighting. There are five main types of lighting available, each of which has their own advantages. Natural lighting is the most preferred type, as it is soft and flattering. For more controlled lighting, task lighting and ambient lighting are the best choices. They provide a more directional light and have distinct purposes. Accent lighting, such as up lights and down lights, are then used to highlight specific areas and features. Finally, decorative lighting can be used to provide an attractive touch to any room. Lighting should be considered carefully when decorating a room. It has the power to change and enhance the atmosphere of any room, and so it should be chosen to reflect the needs of the user. With a carefully planned lighting system, any space can be beautifully lit and the ambience of a room can be transformed.
