The City of Edmonton is replacing all its 98,000 traditional street lights with high-efficiency LED lighting as part of the Neighbourhood Renewal Program.

This year 4,500 light fixtures will be installed in 12 neighbourhoods.  The new lights are 40 per cent more efficient and are expected to last between 15 and 20 years, Coun. Don Iveson said.

The city estimates the conversion will save $4,300 in each neighbourhood per year in electricity and maintenance costs.

The conversion will occur at the same time as streets and sidewalks are replaced, so should result in minimal additional disruption for residents.

"This is one of the largest LED replacement programs in Canada, and contributes to our goal of making Edmonton a national leader in setting and achieving the highest standards of environmental preservation and sustainability," Iveson said.
