Lighting, also known as illumination or light, is an essential feature of any residential and commercial environment. Lighting helps to set the mood, create an atmosphere, and can be used to focus or direct the eye to certain features of a room. There are many types of lighting available for home and business use. Natural lighting, such as sunlight, is always beneficial and can light up a room in the most natural and cost-effective way. Artificial lighting can also be used to supplement natural light and to provide light in areas where natural light is lacking. Common types of artificial lighting include incandescent, halogen, fluorescent, and LED lighting. Another popular form of lighting is task lighting. Task lighting is used to brighten areas of a room where specific activities take place, such as studying, cooking, or crafts. Task lighting is available in many forms, such as pendant lights, wall sconces, track lighting, and recessed lighting. Finally, accent lighting is used as to create a certain ambiance and to emphasize elements in a room such as art pieces. Types of accent lighting include wall washers, picture lights, and track lighting. Lighting is an important part of any space and should be considered when designing a room or an outdoor space. A combination of ambient, task, and accent lighting can make a room feel comfortable and inviting.
