General or Ambient lighting as it is called, provides for basic lighting
needs. The best way to describe it is a comfortable level of light. Not
enough to do specific tasks but enough to navigate through rooms,
hallways and stairways safely. Using incandescent for general lighting a
basic rule is 2-3 watts per square foot. With fluorescent light about 1.5
watts per square foot is adequate. This is just a basic rule of thumb.
Many factors can alter the amount of light such as paint color, furniture
color and size, heights of ceilings etc.
General lighting can be achieved by means of different types of light
fixtures including but not limited to recessed cans, ceiling mounted
fixtures, wall sconces, table lamps etc. The choices depend on the light
output of a fixture and the style one is trying to achieve.
