washing, showers and similar areas of high humidity to insure proper

fixture operation and longevity.

such as fluorescent, high intensity discharge (HID) or high pressure

sodium. Do not use low-pressure sodium.

(b) Consider safety and security for the public in the lighting design.

Installation of lighting fixtures should limit spill light and

excessive glare to adjacent private and public property.

Illumination Levels of this manual, shall be the minimum maintained

values for interior parking facilities.

garages to ease the adjustment from daylight to the low-level lighting

inside the garage. Provide a photoelectric sensor to switch these

fixtures on during daylight hours and off at night.

fixtures. Provide details and/or manufacturer's name and catalog

number, if possible.
