Floodlights

• Must be 600 lumens or less in brightness per fixture (Section 102-4A)*

• 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)

* Note that there is a limit on the total lumens allowed for all fixtures (combined) that aren't fully shielded (see Section 102-4C(2)). For this reason, we recommend using fully shielded fixtures, whenever possible. In some cases, a shield can be added to floodlights with exposed bulbs to convert them to fully shielded fixtures. (See examples of add-on shields for floodlights here.)

Exception:  

Floodlights used for safety and security that are on only temporarily (e.g., on a motion sensor) are not subject to these restrictions. (Section 102-7C)

• Must be 1500 lumens or less in brightness per fixture (5000 lumen or less on nonresidential properties) (Section 102-4C(3))

• 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)

• Nonresidential properties: On nonresidential property, floodlights used for safety and security may be used throughout the night only if any fixture with a lumen output above 600 lumens is dimmed by at least 50% (Section 102-4D(2)).  Otherwise, they must be turned off within one hour after closing and not turned on more than one hour before opening (Section 102-4D(1)).

There is a cap on the total lumens allowed per site (Section 102-4C(1)), all fixtures combined, so we recommend using only 700 to 1300 lumens per fixture for this kind of lighting.

* To qualify as fully shielded, floodlights with adjustable aiming must be installed and aimed so that no light is emitted upward (Section 102-3, definition of "Fully Shielded Luminaire").

Exception: 

Floodlights used for safety and security that are on only temporarily (e.g., on a motion sensor) are not subject to these restrictions. (Section 102-7C)
