Lighting, also known as illuminance, is the means by which we bring light into a space in order to provide visibility and to affect our environment. Lighting can be provided by natural or artificial sources, depending on the needs of the space and its inhabitants. In the past, natural light was the only form of lighting available, but with advancements in technology there are now various forms of artificial lighting to choose from. Artificial lighting can provide a number of functional and aesthetic benefits in various spaces, from illuminating a workspace or living area to creating a specific atmosphere or highlighting certain features. Different types of light fixtures offer different levels of brightness and color, which can be adjusted to suit the needs of the space. From an energy efficiency perspective, LED lighting is the most efficient choice for most applications, using around 90% less energy than traditional incandescent lighting. LED lighting is also longer-lasting and more durable, making it a good investment in the long run. Overall, lighting is a significant factor when it comes to designing and creating a comfortable, functional, and attractive environment. With the right combination of natural and artificial lighting, you can create a space that suits your individual needs and speaks to your personal style.
