Reportedly, the Nova Scotia of Canada is reviewing the possibility of replacing 120,000 street lights across the province with LED lighting.
 
According to ministerial briefing notes prepared in January for newly installed Energy Minister Charlie Parker, the estimated cost of installing LED provincewide would be $90 million.

The documents obtained through a freedom of information request say the opportunity exists to cut street lighting electricity costs by more than 50 per cent and there would also be annual maintenance cost savings based on the 20-year life expectancy of the lights.
 
According to Bruce Cameron, the Energy Department's director of strategic policy planning, the $90-million cost would be returned through an equivalent amount in savings in energy and maintenance costs over a 10- to 13-year period.

He said any final decision on whether to proceed with a policy initiative would rest with the minister and cabinet.

It’s said that Nova Scotia has taken a number of pilot projects and last month the Transportation Department awarded a $3.2-million contract to convert 2,500 highway lights from high-pressure sodium bulbs to LED technology.

And last fall the city of Halifax purchased more than 2,000 LED street light fixtures at a cost of $1.6 million.
