Lighting is the use of light to achieve a practical or aesthetic effect. Indoor lighting is commonly accomplished using electric light sources, such as incandescent bulbs, LED, compact fluorescent lamps and/or other forms of illumination such as rope lights, or by natural light from windows or skylights. Outdoor lighting systems are used to illuminate building exteriors, securing grounds, outdoor recreational areas, or other areas. The right kind of lighting in the right area can be beneficial and even comforting. The right kind of lighting can be energy efficient, cost effective, and provide the necessary level of illumination for any given activity. From a psychological perspective, lighting can affect mood, feelings, behavior, and productivity. Good lighting can therefore promote a positive mood and feelings of safety and comfort. Lighting is also important for aesthetic appeal. The right lighting will make a space look bigger and brighter, helping to create a pleasant atmosphere. There are various types of lighting fixtures to choose from, such as recessed lighting, pendant lighting, wall sconces, and chandeliers. Overall, lighting plays an important role in everyday life, whether it is for practical or aesthetic purposes. It enhances safety, increases the functionality of a space, and can even affect ones mood. The right kind of lighting should be carefully selected to fit the needs of the environment.
