Lighting is a key element in the design of a home or office. The quality and type of lighting can create a dramatic effect on the mood and atmosphere of any room. Properly selected and placed lighting can provide the correct balance of brightness and contrast. Natural lighting is available from the sun, so it is important to consider window placement when designing a home or office. Natural sunlight can be filtered and spread throughout a room so that it isn't blinding, but still provides a bright and comfortable atmosphere. It can be used to highlight an object or wall, as well as provide an overall soft light. For those times of the day when natural light isn't available, artificial lighting is often used. There are three main types of artificial lighting: overhead, task, and accent. Overhead lighting is a general lighting source, providing a broad illumination that covers the entire room. Task lighting is directed to provide a more concentrated illumination, such as a desk lamp or floor lamp. Accent lighting can be used to highlight a wall or object. Lighting should be considered carefully before making a purchase. It is important to consider the size of the room, the desired level of brightness, and the types of activities that will take place in the room. There are many different styles and types of lighting fixtures, so it is important to find one that is the best fit for the space. Lighting can really transform a room and create a unique atmosphere. Careful consideration and thought can help to create a space that is comfortable and inviting.
