Project Overview

The Town of Chester has been working with Tanko Lighting since spring 2017 to convert the Town’s streetlights to high-efficiency Light Emitting Diodes (LED) fixtures from the existing High-Pressure Sodium (HPS) system. This project will replace approximately 312 streetlights throughout the Town of Chester, including standard streetlights (called “cobra heads”) and decorative streetlights.

LED Technology & the Benefits of LED Streetlights

LEDs are a technology that has been used in solid state lighting for decades. More recently, LED technology has advanced to streetlight applications. LED streetlights are more energy efficient than HPS fixtures, have an expected lifespan of over 20 years, and produce a higher quality of light than HPS streetlights. The higher quality of light allows the human eye to see more details and colors.

LED streetlight fixtures also have greater control over the lighting distribution. This creates a lighting pattern that distributes light efficiently across the street decreasing light trespass into residents and light pollution caused by light bleeding upwards into the sky. This combined with higher light quality allows the wattage of the fixture to significantly decrease. For example, the Town will be replacing many 50W HPS fixtures with 22W LED fixtures.

The Town of Chester is interested in reducing its energy consumption and maintenance costs associated with streetlighting. Installing LED streetlight fixtures will save energy, require less maintenance, and will provide citizens with better light quality on streets and roadways. The Town also wishes to complete the LED conversion to create more consistent streetlighting throughout the Town.

The Town has chosen the 3000 Kelvin light temperature which is a warm white color but still warmer compared to early generation LEDs. This is the recommended color temperature and will provide a clear but soft light.

Each year, the Town is estimated to save approximately $45,000 in energy costs. By converting its streetlights to LED technology, the Town expects to prevent 65,762 tons of carbon dioxide emissions per year.

To minimize the environmental impact of the program, the existing High-Pressure Sodium (HPS) streetlights will be recycled in accordance with federal and state environmental guidelines.

Streetlight Conversion Schedule

The Town is working with a local contractor to convert the majority of Town-owned streetlights starting the week of 10/30/2017 and continuing through November 2017. The Town will convert a small group of decorative streetlights in the future as part of the Main Street Project.
