Map: 10 locations for LED streetlight testing across Capitol Hill

New glow on 16th Ave E

We interrupt our normal flu pandemic reporting for this coverage of a less serious but still quality-of-life affecting topic: the new LED streetlights being tested by the city at 10 different locations across Capitol Hill.

Neighbor John writes:

Maybe you've posted about it, but the city recently installed l.e.d. streetlights along the 1100 block of 16th ave. e. (and some other spots, I've heard) to test them vs. the older sodium lights. On our block, neighbors are flipping out about how strange the newer lights are. The funny thing is that the city didn't let people know about the lights ahead of time. I learned about it from the guy in the truck installing them. Maybe you've heard more about what they're up to and what the benefits of the new lights might be.

I talked again to Mike Eagan, spokesperson for Seattle City & Light. He provided information when we came calling looking for details on another area where the city is testing these new streetlights on Capitol Hill at Aloha and 10th.

Here's what he told us then about the potential value of LED streetlights:

LEDs have the potential to lower energy use and maintenance costs, but we want to see how they work in the field before making any decisions.  Our hope is that they will align closely with our overall conservation goals as captured in our Five Year Conservation Action Plan.  However, any additional efforts to expand the LED project will depend on available budgets.

The city has more to say about the pluses of going LED in this press release. Here's the map of Capitol Hill locations that either already have the new lights or will get them soon.

So, back to neighbor John and some of people on 16th Ave who may be, as John put it, 'flipping out.' I decided against knocking on doors in the area -- hopefully a 16th rep or two will chime in here in comments -- but I did ask Eagan why there wasn't more notice and what his department was planning to do to gather feedback.

Eagan said the city did not flyer or send out mail notices of the tests but did issue a media release. "We want comments from the community," Eagan said, adding that a consultant is being hired by the Department of Energy who is helping to run this trial. "We're still working on the survey," Eagan said. "It will be available online and taken to the doors."

In the meantime, you can contact City Light customer service with any issues you'd like addressed in a shorter timeframe. That number is (206) 684-3000.

Eagan said the trial will continue for several weeks with a goal of delivering a final report to City Light brass by the end of July. You might notice different lighting at different locations as the city is testing bulbs from six different manufacturers.

I like them
I was driving through the 10th/Aloha area with a friend last night and she saw them for the first time. She exclaimed how much better she liked them than the sodium lights, and I tend to agree. Looking forward to the Broadway/Roy installation!

Maybe....
They didn't tell anyone, because the moment they did all sorts of weirdos would crawl out from under their rocks and voice opposition to it.

This way, they can just put them in and see what people say. No chance for the professional hand wringers to wring their hands ;-)

yes
I like these!

They seem brighter than necessary, but I think they are an improvement over the old ones which suddenly seem very yellow.

Yes let us emerge from the Time of the Yellow Nights which we hadn't even realized was upon us.

creepy
I'm all in favor of new lighting technologies, but take a stroll down the 1100 block of 16th ave. e. and see if the new street lights don't cast an unfamiliar, if not downright unpleasant, glow. I want to like these, but lighting the whole neighborhood/city this way would take a lot of getting used to. The traditional sodium lights radiate at wavelengths much more comfortable to the human eye. (That's why you can grow plants under them.) The l.e.d. spectrum seems like the beam from an alien saucer just before you and your family are abducted.
I'm curious how much these lights save on energy use, especially when factoring in the disposal of functional older lights.

RE: creepy
I'm not an expert but my understanding is the energy savings are one benefit, but the maintenance of LEDs over traditional lighting represents a bigger financial benefit. The old lights have to be replaced far more frequently at great cost -- and that's if they even are replaced. My wife and I see a ton of lights out all the time, we'll be happy to have reliable lighting, even if it's a space-age hue.

Not bright enough
I live on Summit Ave E and we have 3 of the new l.e.d. lights on our block. I have to say the color is better but not nearly bright enough. Maybe the poster who thought they were too bright has a different brand, but ours are quite dull at street level. I don't think they light up the street sufficiently at all. I find it curious that the city did nothing to tell us about the test and that they wanted feedback! So typical Seattle--they don't really want feedback--they have already decided on what they are going to do and only want to appear as if they care what we think.

deathly....zombie light
they are testing different kinds all over the city. the ones on 16th are awful. horrible.

the new led's emit a deathly blue light that makes people look like zombie's at night. and they are REALLY bright. the one across the street from where i live lights my whole house up to the point where i can read a book in the darkness of my house at midnight.

also the pollution they emit is outrageous. they may not emit light upwards, but one light makes the street look like a runway at sea-tac.

is there no light that has a warmer glow? these are cold and very blue/white.

lighting fail, city. go back to the drawing board.

How bright is too bright?
Two important features of street lighting, clarity of color and amount of lumens, are important safety features of outdoor lighting. Current sodium lights eliminate much of the usable color spectrum, rendering cars and clothing either "dark" or "light". Was that car that just hit you black? blue? green? In daylight, the color differences will be profound, under sodium lights, well...you know...it was dark...

The same holds true for clothing on people, and for facial recognition on the sidewalks. Can you really see through those shadows to make a good i.d. of someone that just stole your wallet? Even in low-level LED light you can get a color-correct sense of those things.

Lumens - how bright the thing really is...the human eye needs time to adapt to seeing in low light conditions, and then again, 20 minutes to fully adapt to dark conditions after exposure to bright light. This is important because if the streetscape is too bright, your retina will be "bleached" and you will not be able to see what is crouching on your porch when you go home. Is that a dog? a person? a gnome? Oh, Joey returned my shopping cart.

Successful and safe street lighting will be color correct, and not so bright that it makes deeper shadows or impairs human vision in nighttime conditions.

You might be surprised at just how little light needs to be present when it's the *right* kind of light. As you are walking through these areas, check out how clearly you can recognize details of faces and car colors. You might get a sense of what the differences are between the different test zones.

CPTED = "crime prevention through environmental design" (honoring the human physiological needs in creating safe environments)

Here is a somewhat clear explanation of CPTED ideas: http://www.mesaaz.gov/police/literature/cpted.aspx
