Conversion to LED Streetlights

This page updates the community about the conversation of existing conventional lamps to brighter, whiter LED bulbs.

BACKGROUND

In summary, the conversion from sodium vapor streetlights to LED streetlights hasn’t been as good as many hoped. Expected & desired improvements (lower cost, lower energy use, potential improvements in safety) have been counterbalanced with notable undesirable outcomes (light intrusion, detrimental health/environmental impacts, a sterile looking streetscape) that were unknown or unexpected before LEDs bulbs were installed in our neighborhood.

The streetlights we are used to - lights that have sodium vapor bulbs - have a warmer color (closer to a “candle light”) than the new LED bulbs which emit colder, bluer, “daylight balanced” light. LED lights are experienced as brighter and harsher than sodium vapor lights resulting in a more sterile feeling. In addition, numerous Upper Monroe residents are reporting unwelcome light intrusion into their private spaces, interrupting sleep in cases where LEDs are positioned such that the lights are shining, unobstructed, into second floor bedroom windows. Add to this international studies that reveal a host of negative impacts resulting from municipal-wide LED lighting systems on human/animal/environmental health in general; not something Rochester has had to confront until now.

Everyone agrees LEDs deliver on their promise to reduce energy use and reduce cost burdens. At the same time, some residents perceive LED lights as a tool to reduce crime even though most independent studies (Those studies not funded or supported by commercial LED interests.) are inconclusive on the effectiveness of the sort of incremental changes in illumination provided by LEDs (i.e., whether LEDs are factually more effective than sodium vapor bulbs). Of course, the benefits of lower operating costs and lower energy usage can only me improved with even lower wattage settings on LEDs.

Perhaps most importantly, while sodium vapor lights can not be adjusted LED bulbs provide multiple adjustments to both the light wattage/intensity and color. The best outcome will result from adjustments to minimize the negative impacts while maintaining any marginal increase in effectiveness.

UPDATE: August, 2025

After careful consideration and discussion on August 17, 2025 the UMNA leadership team approved the following position on LED street lights in our area:

"UMNA will pursue reducing the brightness of streetlights to the lowest level (35 watts) and adjusting streetlights to the warmest color (3K)."*

*Undertaking this effort may take an extended amount of time and will require reaching out to UM residents about the pros and cons of adjustments to lighting controls before advocating with the City administration.

BACKGROUND | Published in the January 8, 2025 UMNA e-Newsletter

Over the past couple of months new LED bulbs have become apparent on a number of side streets in Upper Monroe. Conversion to LED bulbs has been taking place on main roads in the City of Rochester for some time. (All of Monroe Avenue in the City is now lit by LEDs.) The replacement of lights on the side streets, however, is just getting underway in UM. The older, yellow-er “conventional” bulbs are being phased out. As they fail the street lights are retrofitted with new LED bulbs. City representatives we talked to were unclear about when to expect wholesale replacement.

As you can see in the photo of Shepard Street above, the new “daylight” white LED bulbs are very much whiter and very much brighter than the old bulbs. LED bulbs are expected to be cheaper to run, last longer and cheaper to replace according to the City of Rochester’s Office of Environmental & Sustainability.

Some of the neighbors living in proximity of the new LED streetlights, however, aren’t at all happy about the changeover. Informal reports from affected residents indicate the whiter, brighter LED bulbs throw light further than the current bulbs. As a result, the stronger bulbs have been illuminating nearby street-facing rooms. Even at some distance, neighbors tell us the brighter light can be perceived as intruding into living spaces to a greater degree than conventional lights.

Recognizing that eventually ALL the current conventional bulbs will be replaced by the new LED bulbs, a number of neighbors are decrying how the combining effects of even stronger lights along city streets will disturb the natural environment. We know how concentrated, intense lighting reduces visibility of the night sky. Brighter lights are certain to worsen the problem. These factors are known to adversely affect humans; physically as well as psychologically.

There are neighbors concerned about crime who see the new bulbs as a desired feature they associate with deterrence. Cost conscious neighbors welcome the long term economic savings they hope will reduce the size of future tax rate increases. Those concerned about climate impacts have expressed support for the benefits of a reduced carbon footprint in this energy usage category. Why isn’t it happening faster, they ask. So, it’s a mixed bag.

There may be ways to mitigate at least some of the concerns and retain most of the benefits. A group of interested neighbors is poised for action. If you would like to learn more, please reach out to [email protected].

2025 January 25 | Discussion: Conversion to LED Streetlights

Community conversation about the conversion to LED streetlights held on Saturday, January 25, 2025 at a private home in Upper Monroe

Attendees: Michael Amy (Shepard Street), Rome Celli (Werner Park), Mary Anne Cole (Jersey Street), Elizabeth Goins (Crosman Terrace), Tim Guyot (Alliance Avenue), Adam Herdzik (Crosman Terrace), Laurie Kash (Shepard Street), Robert Sandgrund (Shepard Street), Kerria Weaver (Democrat & Chronicle) and Jeanne Weber (Alliance Avenue).

Next Steps:

  • Advocate for the usage of "amber" colored LED bulbs;

  • Generate and examine field data from around Rochester to determine LED performance relative to dark skies compliance;

  • Generate and examine field data to determine the actual level of illumination, intensity and throw;

  • Advocate for more effective shielding in cases where affected neighbors experience light intrusion;

  • Advocate for deeper community engagement in ongoing efforts to convert to LED lighting across the city;

  • Take a look at municipalities in other areas of the United State that have adopted overarching "dark skies" standards. What were their goals? What data was used to decide their standards? What are the demonstrable, objective outcomes since the standards have been implemented?

  • Based on what we have learned update/revise any potential opportunities for individual residents;

  • Be mindful of other related potential impacts such as digital billboard signage proposed along Rt. 490 in sight of Upper Monroe and Cobbs Hill Park; and

  • If potential widespread modifications are available for the neighborhood, gather and share broad-based information about what is possible and then solicit many perspectives and inputs to see if a consensus emerges.
