LED Street & Safety Lighting Conversion
The City of Poway currently has approximately 3,300 low pressure sodium (LPS) street and safety light fixtures that are operated and maintained through funding by the Lighting District. As of June 2019, LPS light fixtures are no longer being produced. Light emitting diodes (LEDs) are more energy efficient and many cities have already converted their LPS lights to LED. Therefore, the City has embarked on a project to convert all the LPS light fixtures to LED.
Conversion of the decorative lighting in the Old Poway Park and Civic Center Drive areas will be completed as part of a separate project due to the complexity of the retro-fit required for those fixtures. Additionally, a third project will convert the City’s parks and parking lot fixtures.
In July 2019, the City Council awarded a design-build contract to Tanko Streetlighting, Inc. to help the City select a product that not only meets the Poway Municipal Code standards for LED lighting but is field dimmable and allows for installation of light trespass shields. The goal is to select a product that will present the most savings to the City through a combination of installation costs, energy use, and long-term maintenance costs. The light selection will also take into account conservation of the night sky, in that the brightness of the lights is enough to meet but not exceed the needs of the Safety Services Department.
Tanko Streetlighting, Inc. has completed an audit of the City’s street lighting system. The audit was conducted during the day and provides additional information for our streetlight database such as more accurate pole locations, pole height, mast arm length and distance from the street to the light pole. This information was important for completing photometrics for the lighting which was part of the design process. The photometrics show how much light is being cast by the proposed fixtures.
With assistance from Tanko Streetlighting, GE was the manufacturer selected to provide new LED street and safety lights. Staff selected two different wattage fixtures, an 84-watt unit for arterial and collector streets and 39-watts for residential type streets. Both fixture types have 2700 Kelvin color temperature which meets the maximum allowable for residential streets and is lower than the maximum on arterial and collector streets.
Sierra Pacific will be completing the physical conversions starting the week of February 18. Below is a link to a GIS map showing where installations have been completed. The gray icons show where installation is complete. This map will be updated on a daily basis.
