Lighting is a term used to describe the use of illumination in a space, room, or other area. It is used both for practical reasons, such as providing safety, security, and aesthetic purposes. Lighting is the use of lights to provide visibility, to emphasize or highlight certain elements and create a specific atmosphere, or mood, in a room or place. Common uses of lighting include task lighting, such as kitchen and bathroom lighting, as well as general lighting, like chandeliers and pendants, which are more decorative and are used to add ambiance. The right kind of lighting can dramatically change the look and feel of a room. Using a combination of various types of lighting, such as accent lighting, can make the space look more inviting, while the right kind of task lighting can make a room brighter and more efficient. Different types of lighting also have different effects on energy performance, both in cost and in terms of energy savings. LEDs, for example, are more energy efficient than traditional light bulbs because they emit little to no heat, and can last up to 25 times longer than traditional lighting. During the day, natural light can be used to brighten and warm up a space. Light from the sun can be controlled through the use of window treatments and shading devices, for example shutters, curtains, and blinds to allow natural light in and block it out selectively when needed. Lighting is an essential part of any space, and it can help to create a unique and inviting atmosphere. Whether its for practical or aesthetic purposes, the proper lighting can make a huge difference in a space.
