Letter: Worried about impact of LED streetlights

Original post made on Mar 20, 2013

A few nights ago I went out at midnight and saw that new LED streetlights had been installed on our block on Pope Street. I was shocked to see how bright they were — with a sickly, electronic light — and immediately wondered about the health impact on sleep cycles of people, animals, and even plants.

I am a big fan of LED lighting. Their beam shaping possibilities and high speed modulation make for interesting possibilities. Their relatively broad band emmission (compared with sodium or mercury lamps with strong spectral lines) renders them less light polluting.
Modulation of these lamps could provide critical messaging to vehicles with appropriate receptors.

I like the lights. Thank you, Menlo Park! I heard the brightness can be adjusted; please don't dim the lights unless all neighbors near it agree.

As usual, cost is an issue. If it weren't, there'd be a simple solution: put motion detectors on these streetlights. Many Menlo Park households, including mine, have motion-sensor-activated floodlights on their property to discourage prowlers and make it unnecessary to carry a flashlight into the back yard after dark. There's an initial cost to purchase and install these things, but it amortizes over many years.

The city should consider making this investment. That way, the lights would deliver the safety benefit of greater visibility without contributing to the overall light pollution from our urban area.

[Portion deleted.] You didn't want us to have plastic bags. You got what you wanted. Now you are complaining about LED lights? Could it be that electricity demand for PG&E will drop. No worries. PG&E will make it up with electric cars.
