Light is important in life. Without light we would not be able to see, nor would plants be able to absorb necessary energy. Light is a complex phenomenon that has been studied throughout time. Lighting is the deliberate use of light to achieve a practical or aesthetic effect. In respect to interior design, lighting forms an important part of the feel and atmosphere of a room. The type of lighting used in various rooms can heavily influence the style, mood, and function. In general, a consistent, bright light is necessary for task-based areas such as the kitchen and the bathroom, while some subdued indirect lighting is more suitable for living rooms and bedrooms. In respect to architecture, lighting can be used to add drama and draw attention to certain features. It is also used to accentuate certain details during night time. In a world of increasing energy consumption, it is important to make sure that lighting is used efficiently and responsibly. Overall, adequate lighting is necessary in both interior design and architecture in order to ensure health, safety, and practicality. Each room has its own needs in terms of lighting and those needs should be carefully considered in order to maximize the functionality of the area. Furthermore, tasteful use of light can create a suitable atmosphere that enhances the overall look of the room or building.
