LIGHT LEVELS


The general approach toward lighting has always been "the more the better." This is not necessarily true as the proper amount of light need must always take into account the visual requirements of the task in the particular environment.

Lighting that is good for one task may be inappropriate for another. This section covers some interior lighting guidelines when specifying or evaluating lighting levels.

Outdoor lighting must provide sufficient lights for safety and security reasons. Although there may be some aesthetic reasons, the more upscale the neighborhood, the more important it would be. Lights can enhance the architectural features of the building.

Many downtown skylines had become quite interesting and beautiful because of specialty lighting on the building facade and also attract more business, giving revitalizing feel of "we are open for business after dark." Therefore light levels may be well above recommended level.
