Solar-Powered Sidewalk Lighting:Solar Powered sidewalk Lighting(ST7696-1)

NYS Department of Transportation


Solar-powered walkway lighting is a cost-effective alternative to conventional walkway lighting when low illuminance levels are acceptable. This project will mark the first time that lighting powered by a renewable energy source is used to illuminate a walkway on a New York State Department of Transportation (NYSDOT) project.

Project Description

The project demonstrated and evaluated a solar-powered lighting system, with smart controls and battery back-up, developed by Selux Corporation, Highland, NY (under NYSERDA Agreement 4868). Forty-five of these fixtures, each housing a 42-watt compact fluorescent lamp and providing an average illumination of 0.5 foot-candle of light, were installed along a 1 km (0.62 mile) portion of sidewalk. Specific tasks included: (1) development of a detailed lighting design and specification using the Selux fixtures for the walkway project; (2) installation of the fixtures; (3) pre- and post-field testing of the solar-powered lighting units by the Rensselaer Polytechnic Institute Lighting Research Center (LRC); and (4) publication of the results of the evaluation as a Field Test DELTA report.


The solar-powered lighting system offers a low cost lighting alternative to conventional sidewalk lighting for local governments, and provides walkway lighting for pedestrians after dark.

Project Results

The fixtures are installed at a pedestrian walkway in Greenwich, NY. Initially there were some operational problems during the coldest days of the winter the batteries were not sufficiently charging and the lamps were prematurely failing (burning pinkish) due to the insufficient power supply—but these design issues were corrected by installing new chargers and lower watt CFLs. The Town of Greenwich has assumed full ownership and responsibility for the fixtures.
