Lighting is the use of light, both natural and artificial, to create an environment. It has a significant effect on the appearance, safety, and functionality of any space. Natural lighting is an essential part of good design; it can provide both visual and emotional benefits to any space. Artificial lighting is important too, especially in interiors that lack natural light. With the right lighting, any room can be transformed from dull to exquisite. The fixture, shade, and bulb type should be carefully considered to create the desired atmosphere. In addition, a combination of different lighting to provide task and ambient lighting is also important to create an enjoyable space. Modern lighting technologies, such as LED, have made it easier to increase efficiency while also creating a more visually appealing space. LEDs cost less to operate, are more environmentally friendly, and produce a better quality of light. Overall, lighting is key for a successful interior design and it provides an opportunity to create a unique and enjoyable space. Good lighting design will enhance the beauty of any space, maximise its functionality, and improve its overall safety.
