HOW TO LIGHT IT
Once you have analyzed the space and decided what to light, you can decide how best to light it, using three basic lighting techniques:

Ambient Lighting provides general, overall illumination that:

- enables one to move about easily and safely

- defines the space

- makes for a comfortable visual environment

General lighting- brightens objects and surfaces in the lower part of the room creates a feeling of warmth and intimacy, whereas indirect lighting, directed to the upper walls and ceiling, gives the space a cooler, quieter, more spacious look.

Accent Lighting- light to view what's special. Accent lighting directs extra light and thus extra attention to selected objects and surfaces. Accent lighting draws the eye, provides dramatic interest, adds excitement. It says, "Look Here!"

Task Lighting- light to work by. Task lighting illuminates areas where work is performed: reading, paperwork, food preparation, laundry, games and hobbies. Paperwork and reading generally require plentiful, well diffused light coming from over the shoulder or from the side. For kitchens and hobby tasks, a concentrated light from above usually works best.
How Much Light
The amount of light required for goodvision depends on three factors:

- The age of the people using the lighting

- the speed and accuracy required

- the reflectance of the task

Older people require much more light; (at age 55 we need twice as much light to see as well as we did at age 20) they are also much more sensitive to glare, so their lighting must not only be plentiful, but well shielded.

Where To Place The
Lighting

A key element in how to light is where to place the lighting. This is especially important in avoiding glare and veiling reflections. It is also a determining factor in whether a surface texture is to be emphasized or minimized.
