Lighting is the most important element of any room. It can create a mood and atmosphere, it can set the tone for a room and it can even change the way that people feel in that space.
There are many different types of lighting, but they can be broken down into two main categories: ambient lighting and task-specific lighting. Ambient lighting is what you see when you walk into a room - it's general light that fills every corner of the room evenly. It also includes overhead lights or lamps. Task-specific lighting is used for specific tasks like reading or cooking.
