In the light fixture (above) the
spectrum, has an unusually high
amount of blue. This blue is like
daylight and is problematic.
Located on Hatcher street the
horrible, blinding, plus bad glare are
what folks have described as
problematic for bicycles riders and
pedestrians.
This cobra head streetlight (above)
is considered unhealthy for people and
wildlife because it is 4000 Kelvin - the
daylight at nighttime effect.
This ‘daylight’ streetlight is on
Hatcher Street near Central Ave.
(2017). Update: LED bad streetlights
are being replaced with better 2700K
fixture - 2019 about 100,000 have
been replaced in City of Phoenix.
YUCK

This LED streetlight 4000K
SUNNYSLOPE is a neighborly
area we love. Once part of the
county, today Sunnyslope is
within the City of Phoenix -some
folks even call it ‘downtown’.
Many positives exist for
Sunnyslope including the
Mountain Preserves, parks, good
restaurants and new neighbors.

New 2700 Kelvin Light Emitting
Diodes (LED) streetlights are popping
up everywhere in the City of Phoenix!
A few years ago the city decided to
replace old High Pressure Sodium
(HPS) streetlights with new LED
streetlights. Soon many
neighborhoods began seeing the
‘horrible’, blue, 4000 Kevin LED
streetlights. The unusual ‘blue spike’
of LED lights was not understood and
the city survey had basic flaws. Yet
the majority of residents showed that
they did not like the ‘test’ 4000K LED
streetlights.
Based on professional experience
of several neighbors who recognized
and explained the potential health
issues to aids and council members.
The points related to bad LED lights
for us, wildlife, and our quality of life
that Phoenicians cherish became a
base line. The team helped block-
watch groups, city staff, and council
members learn about the LED
problems and a solution. The newer
2700K LED street and park lights
matched with excellent energy
efficiency.
The Phoenix City Council,
approved 9-0 the bid for 2700 Kelvin
streetlights (about 100,000) on 11-30-
16. Soft White Wins!
Installation since then make the
transition of streetlights nearly
complete in 2019. However, new
lights in Parks will be more
incremental over a decade.
Many towns and cities are now
choosing ‘soft-white’ LED. More
about LED here. Channel 12
report showing many folks don’t like
painful, bright, LED lights (10/7/16).

City of Phoenix
survey was unclear
on web site…
…but more then half the
Phoenicians that took the
survey did not like the
4000K LED streetlights.
Neighborhood groups
and many associations
also asked the City to
reconsider new street
and park lighting.
Neighborhood Block
Watch leaders asked the
City to reconsider LED
lights and specify 2700K
fixtures for most
applications!
Phoenicians found the
city departments willing
to take a second look at
the rapidly improving LED
technology. A second
look found the request of
neighborhoods of 2700
Kelvin LED possible with
excellent energy
efficiency. So everyone
got better, safer, LED
lighting on our streets
and parks!
The blue hue from LED lights like this
one on Hatcher are being avoided now
as the City of Phoenix replaces this
fixture with newer ‘soft-white’ LED
rated at 2700K!
AVOIDING Blue Hue from
Light Emitting Diode (LED)
for night lighting is the
smart thing to do!
