Lighting is essential in any environment, no matter residential or commercial. Good lighting can dramatically change the feel of a room, provide the necessary illumination to undertake daily activities and highlight the special features of a space. The aim of lighting is to create moods, atmospheres and functionality in different spaces. Poor lighting can cause eyestrain, fatigue, and headaches. It can create an oppressive, dark atmosphere and have a depressing effect. The correct balance between ambient lighting and task lighting should be struck. There are many types of lighting, with the main types being ambient, task lighting, accent lighting and natural lighting. Ambient lighting is designed to provide overall illumination in a room and may be provided by ceiling, wall and floor lights. Task lighting focuses on specific work surfaces in order to reduce glare and provide additional light for completing a task. Accent lighting is used to draw attention to art, design elements or architectural features and is usually in the form of spots, strips or uplighters. Natural light has the ability to transform a room and gives a sense of brightness. Lighting should be tailored to individuals and their personal needs, whether that is providing an energetic environment or somewhere that is tranquil and calming. The possibilities with lighting are close to endless and many combinations and permutations can be explored and achieved.
