Lighting
Lighting is one of the most important features within an indoor space. Lighting can help draw attention to a certain area or object, brighten or die down a room, and help mkae certain tasks easier. The main types of lighting include ambient, task, and accent lighting.

Ambient-
provides an area with illumination. Also known as general lighting, it radiates an even level of brightness without glare. Having a central source of ambient light in all rooms is fundamental to a good lighting plan.
How to be accomplished-
Chandeliers, ceiling or wall-mounted fixtures, recessed or track lights.
Task-
For specific tasks- reading,  preparing and cooking food, doing homework, working on hobbies, or playing games.Task lighting shouldn't have any distracting glare or shadows.
How to accomplish-
Recessed and track lighting, pendant lighting and undercabinet lighting, as well as by desk lamps.

Accent-
Adds drama to a room by creating visual interest.  Can be used to draw attention to houseplants, paintings, sculptures and others. It can also be used to highlight the texture of a brick or stone wall, or window treatments. Requires at least three times as much light on the main focal point as the general lighting surrounding it.
How to accomplish-
Recessed and track lighting or wall-mounted picture lights.
