Description
Is the city looking into adopting better regulations for shielding and/or lowering the color temperature of the new LED streetlights being installed? The American Medical Association has recently adopted a guidance that urges communities to think carefully when upgrading streetlights to LED. Despite the many benefits (longer life, efficiency, etc) the LED lights being installed in many cities, including New Haven, increase glare and disrupt the sleep health of human and non-human citizens alike. The AMA suggests minimizing blue light (the most disruptive during night), properly shielding lamps, and dimming lights during off-peak hours. What is New Haven doing about this issue?

[Sorry for this lengthy note]
The relationship of street light and crime is an understandably sensitive issue especially in high crime neighborhoods. The Police and City like to repeat street lighting, and more so, house lighting by you, makes you safer [deferring cost to you], vs providing actual security to the homeowner [i.e the Hill district project]. Counter to everything we have been told, in part to sell lighting: Light and intensity [how bright] does not correlate to reducing crime. It turns out criminals don't like the dark either. Or wireless security systems. The Dark Skies group reports [among others, please see National Institute of Justice, below] on a study in Chicago to reduce crime by increased lighting and saw an increase, or no decrease: bright lights created darker shadows to hide in. In some neighborhoods street lighting is being removed [Seattle] or wattage reduced. San Francisco lighting is now referring to its newer standards as "moonlight", related to reduced intensity. Much of street light is wasted with 30% as sidelight glare - into your house instead of on the ground plan. If you can recover that lost energy you can then reduce the wattage for the same brightness. Everyone might sleep better. Please see:
