Citizens push back on LED lighting

If you don't like what you see, why don't you fight it?
If you know there's something wrong why don't you right it?

TLDR: Citizens around the world are raising hell over LED streetlights they don't like. Cities should consult with citizens before undergoing a citywide replacement.

Around the world, people are seeing the LED streetlights that their city is installing, and many don't like it. In this situation, there are two possible responses: living for a few decades with light you don't like, or pushing back against city hall.

In Berlin, citizens challenged the city's intention to switch from gas lighting to LEDs. The city listened, and a compromise was reached: The Technical University of Berlin invented LED lamps that perfectly mimic the color and brightness of gas lamps.

In Davis, California, a citywide replacement was halted when enough citizens complained. The city listened, and set up a test street to let citizens have a choice in which LED lamps should be installed. The citizens chose lamps that were warmer and less bright. In fact, the citizens choice to reduce the brightness below what the city had planned meant that the city ended up saving even more money than it had originally planned!

But cities don't always listen. The mayor of Honolulu is so far ignoring citizen complaints about a plan to install lights similar to the hated ones in Davis. The city also won't consider dimming or turning off lights in low-traffic areas after midnight, despite the fact that a recent study in the UK showed that this has no measurable impact on traffic accidents or crime. (UPDATE 2015.11.04: Honolulu cancelled their original plan, presumably due to citizen action! Hopefully this will lead to better lights for the city.)

Here is an example of a city official from another city trying to "answer citizen concerns" by telling them how it's going to be, rather than coming up with a solution together:

LED street lighting has a lot of potential benefits. If properly installed, LED streetlights are less likely to shine directly into the sky than older lamps. With careful design, it's possible to avoid illuminating people's bedroom windows. A complete re-design with better uniformity could allow cities to use far less light with equal or greater public acceptance.

Unfortunately, it's also possible to make things worse with LEDs, and one of the aspects that really bothers some people is the color of LED street lights. If you've bought LEDs for your home, you've probably noticed that they have a "color temperature": either a number between 2000-6500K, or perhaps "warm white" or "cold white". As a rule of thumb, the higher the color temperature, the higher the luminous efficiency of the LEDs. But as color temperature increases, LEDs are also generally perceived as harsher, more glaring, and colder. To reduce skyglow and glare, the International Dark-Sky Association recommends using lamps with 3000K or lower.

The lesson from Davis, Berlin, and other cities, is that citizens don't have silently accept what city hall decides is best. If you and your neighbors "raise a little hell", you could end up with lighting that's much better and more comfortable than you have today, with a reduced impact on the environment.

Trooper says:

Nobody's going to help you
You've just gotta stand up alone

But that's not true in this case. Plenty of your neighbors will also share your concern, you can find support from local environmental and city beautification groups, and you can get technical information about what's worked for other cities from the International Dark-Sky Association.

Attractive and effective lighting is something everyone from conservatives to greens can support. So if your city is about to do something stupid, don't be afraid to raise a little hell!
