Lighting is an important tool in architecture and interior design. Good lighting can set the mood, create ambiance, and give a room more depth by highlighting architectural features and colors. Design elements such as window, wall, and ceiling treatments can be used to reflect natural light in a room, while fixtures illuminate a space in more direct ways. Outdoor lighting is also an important part of landscaping and can provide subtle illumination for garden pathways, highlight trees or shrubs, or provide a more practical purpose such as security. Motion sensors are often used to provide light only when needed and save energy. Choosing the right lighting for your home or business depends on the space and the type of atmosphere you want to create. When selecting light fixtures, consider the shape, size, and style to ensure it fits with your existing furnishings and decorating style. Lighting affects the way a space is experienced. A room without proper lighting can appear dull and lack texture. With the right lighting, a room can look inviting, alluring, and luxurious. Lighting designers are professionals who have the ability to manipulate light in a space to create the desired effect with both natural and artificial light sources.
