A5.209.3.2 Luminaire Cutoff Requirements

All outdoor luminaires that use lamps rated greater than 175 watts in hardscape areas including parking lots, building entrances, sales and nonsales canopies and all outdoor sales areas shall be designated Cutoff for light distribution. To comply with this requirement, the luminaire shall be rated Cutoff in a photometric test report that includes any tilt or other nonlevel mounting condition of the installed luminaire. Cutoff is a luminaire light distribution classification where the candela per 1000 lamp lumens does not numerically exceed 25 at or above a vertical angle of 90 degrees above nadir and 100 at or above a vertical angle of 80 degrees above nadir. Nadir is in the direction of straight down, as would be indicated by a plumb line. 90 degrees above nadir is horizontal. 80 degrees above nadir is 10 degrees below horizontal.

Exceptions:

1. Signs.
2. Lighting for building facades, public monuments, statues and vertical surfaces of bridges.
3. Lighting required by a health or life safety statute ordinance or regulation, including but not limited to, emergency lighting.
4. Temporary outdoor lighting.
5. Lighting used in or around swimming pools, water features or other locations subject to Article 680 of the California Electrical Code.

6. Replacement of existing pole mounted luminaires in hardscape areas meeting all of the following conditions:

   1. Where the existing luminaire does not meet the luminaire cutoff requirements in A5.209.3.2; and
   2. Spacing between existing poles is greater than 6 times the mounting height of the existing luminaires; and
   3. Where no additional poles are being added to the site; and
   4. Where new wiring to the luminaires is not being installed; and
   5. Provided that the connected lighting power wattage is not increased.
