General Lighting
Also known as ambient lighting, general lighting provides an area with overall, non-specific illumination. General lighting radiates a comfortable level of brightness, enabling one to see and walk about safely. It can be accomplished with chandeliers, ceiling or wall-mounted fixtures, recessed or track lighting or with outdoor fixtures. A basic form of lighting that replaces sunlight, general lighting is fundamental to lighting a home.
General Diffuse Lighting
General illumination from light cast evenly in all directions. Typical fixtures include pendant globes, chandeliers, and some table lamps.
Glare
Bright lighting that causes discomfort and impairs good visibility. Possible causes may be light sources that are too bright for the application, or fixtures that may not conceal bulbs sufficiently, among many others.
Grazing Light
Directional light at an acute angle, which emphasized texture. The sources of grazing light must be close to the surface. See also Wall Grazing.
Ground or Grounding
Connecting electrical components to earth for safety.
