What is diectional lighting?
Lighting applications are primarily categorized as general lighting,directional lighting,and aesthetic lighting.whereas general (or ambient) lighting provides a uniform amount of lighting throughout an area,directional lighting provides illumination on a work surface (such as a desk or countertop),on an object (such as artwork),or in a particular direction.
Directional lighting is typically used to provide a higher light level than that of the surrounding area and can be used alone or as a complement to ambient illumination.Directional lighting is used when high light levels are required for demanding visual tasks or for accenting purposes.For the purposes of this discussion,direct,task,and accent lighting all belong to the directional lighting category.

The three pnmary types of directional lighting are accent lighting, downlighting, and track lighting. These may be "dedicated" fixtures, where the same type and style of lamp must be used every time or the fixture must be replaced; or"non-dedicated" fixtures, where any replacement lamp that fits the fixture, regardless of the type of light source, can be used.
Accent Lighting Fixtures.
The most common use of directional lighting is for accenting purposes. Accent lighting is used to highight works of art, architectural features, plantings, and other items of interest. Most accent lighting fixtures can be aimed to direct light where it is needed for emphasis, usually with an adjustment range of 35 degrees from vertical, meaning from the ground up to a certain height on the wall, and 350 degrees around, meaning the fixture could swivel horizontally almost all the way around. The most important feature of accent lights is their ability to provide a controlled beam of light.
Recessed accent lights are similar to downlights (see below), but the fixture opening is cut at an angle so that the bulb, or lamp, can be aimed without blocking any light. Some also look like an"eyeball. Average aperture (i.e, fixture)
