Lighting is the deliberate application of light to achieve some aesthetic or practical  effect. Lighting includes use of both artificial light source such as lamps and natural  illumination of interiors from daylight.

Lighting design fixtures for home lighting come in a wide variety of styles for various functions.  The most important functions for interior lighting are holders for the light source, to provide directed light and to avoid visual glare Some are very plain and functional, while some are pieces of art in themselves. Nearly any material can be used, so long as it can tolerate the excess heat and is in keeping with safety codes.

An important property of lighting design for interior lighting fixtures is the wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture for home lighting using replaceable light sources can also have it's efficiency quoted as the percentage of light passed from the "bulb" to the surroundings. The more transparent the lighting fixture is, the higher efficacy. Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability.

Lighting design for home lighting or interior lighting as it applies to the built environment, also known as 'architectural lighting design', is both a science and an art. Comprehensive lighting design requires consideration of the amount of functional light provided, the energy consumed, as well as the aesthetic impact supplied by the lighting system.

The portable or table lamp is probably the most common fixture, found in many homes and offices. The standard lamp and shade that sits on a table is general lighting, while the desk lamp is considered task lighting.
