Lighting is not only used to light your home, it can also be used to beautify your home and emphasize certain aspects. There are 4 types of lighting - ambient lighting, task lighting, accent lighting, and decorative lighting. Using a combination of these lighting types will allow for proper lighting of a room as well as visual interest.
Ambient lighting is used to illuminate an entire room evenly. Ambient light is usually one light in the center of your ceiling from a light fixture or ceiling fan, several recessed lights spread evenly over the ceiling, or natural lighting from windows or skylights. Bright ambient light is important to enable proper cleaning of a room and so you can see where you are going.
Task lighting is used in a concentrated part of a room where more lighting is needed to perform a task. Several examples are a reading lamp, a piano lamp, a billiard table lamp, a bedside table lamp, under cabinet lights, or an appliance light.
Accent lighting is used to highlight certain things. Examples of accent lighting include art lights, plant uplights, Christmas tree lights, lights inside a china hutch, and uplighting that emphasizes a beautiful ceiling.
Decorative lighting is lighting in which the light fixture is a focal point in the room. Chandeliers, decorative candles, light from a fireplace, and beautiful decorative lamps are examples of decorative lighting. Decorative lighting is often the focal point of the room.
Not every room needs all 4 types of lighting, however having multiple types of lighting in a room adds interest. Don't forget to add dimmers to your lights to be able to adjust your lighting and set the perfect mood for your room (and make sure the light bulbs you have allow dimming).
