We wish everyone a good night of sleep. But while some sleep, others are
being affected by BAD, BLUE-WHITE, LED lighting across Phoenix.
Companies have demonstrated they will do LED lighting correctly. Now is
when the City Council should cap LED at 2700K! Waiting ten years for the
1992 Lighting Code to be updated to INCLUDE LED LIGHTS is LONG
ENOUGH.
Phoenicians helped city staff and City Council Members learn about LED
lighting and the harmful effects of LED light fixtures at 4000K & 5000K. In fall
of 2016 City Council voted 9-0 in favor of 2700 Kelvin streetlights!
YET - A DECADE LATER Phoenix is falling behind 24 other Arizona cities and
towns that have an updated Lighting Code. Last year, the Director of
Planning & Development said LED would not be addressed until 2032. But he
added 2034 is more likely before LED lighting will be considered.
While this time line was due to limited staff we provided an “excellent”
example of a modern lighting code. However, that gift did not help.
Much like in 2016, when a key city street staffer said, “I never went to
see the LED lighting test area because I don’t work after 5:00 pm” aka
streets lights on at night. Today - or night - seems like a repeat.
> Horrible LED outdoor lighting continues to grow city wide.
> Blinding LED, and unhealthy LED are still allowed every night.
> Both health and environmental issues are being ignored.
> LED use less energy; but oddly. more outdoor lighting is occurring.
Let your City of Phoenix Council Member know about this serious mistake
made by the City Staff - AGAIN.

NEW 2025 apartment complex
has harsh blue-white 5000K
LED fixtures outside and over
the parking lot. While correctly
shielded, you can see a few soft-white
3000K fixtures mixed with the bad LED
lighting on the exterior of all the
buildings. Nearby is Shaw Butte Mtn.,
that’s within the Preserves. This lighting
is harmful to wildlife and the apartment
residents.
Edison’s incandescent light bulb (2600K)
had almost no blue within our visual
spectrum. Much like a fireplace.

Phoenix had High Pressure Sodium (HPS)
street lights for over 50 years. These
light fixtures only came with one color
level at 2200 Kelvin. Pittsburgh PA
recently installed new LED street lights
rated at 2200K - AMBER wins!
