Save the Night | Be the Solution, Stop Light Pollution
General requirements
- Must be 2700K or less in color temperature (Section 102-4B)(2400K or less is recommended to be the most dark-sky and neighbor friendly)
- Flagpoles can only be illuminated when a flag is hoisted (Section 102-5D(3))
- Flag lighting counts for purposes of the lumen limits stated in Section 102-4C
Under the bylaw, flag lighting may be used throughout the night if it meets these general requirements and the additional requirements discussed next. However, the most dark-sky and neighbor friendly thing to do would be to take your flag down at sunset and not use any flag lighting.
See below for restrictions on lighting a flag using uplighting.
Flagpoles Taller than 20 Feet
Flagpoles taller than 20 ft can only be illuminated using downlighting, using either a fixture attached to the top of the flagpole or mounted above the flagpole on a structure within 15 ft of the flagpole.
The lumen output is limited to 800 lumens per fixture.
See Section 102-5D(1).
Uplighting
Flagpoles that are equal to or less than 20 ft tall may be lit from below provided that:
- There are no more than two spotlights per flagpole.
- The lumen output does not exceed 600 lumens per fixture.
- The light points directly towards the flag(s).
See Section 102-5D(2).
