Global trial shows LED lamps cut street lighting costs up to 70%

NEW YORK: LED outdoor products can cut energy consumed by lighting by more than half, LED products have now reached technological maturity for applications such as street lighting, and Canada and Québec are well positioned to benefit from an LED scale-up. These are the main conclusions of the final report from the global LightSavers project, authored by The Climate Group and LightSavers Canada, released at the Brighter Tomorrow conference, co-sponsored by the Ville de Montréal and Hydro Québec, Québec, Canada.

The report summarizes the results of 14 trials of 29 different LED outdoor luminaire products undertaken between 2009 and 2012 in seven cities, including Toronto, New York, London, Sydney and Hong Kong.

The unprecedented global project, called LightSavers, was undertaken and coordinated by The Climate Group in collaboration with the Toronto Atmospheric Fund, who piloted the original initiative in the Greater Toronto Area.

“Almost a fifth of global electricity is used for lighting, so cutting lighting energy by half would eliminate CO2 emissions equivalent to taking a third of the world’s passenger vehicles off the road,” said Jim Walker, The Climate Group’s International Programmes and Strategy Director.

The primary aim of the global LightSavers trials was to assess the quality and performance of LED illumination over 12-16 months in a variety of climactic conditions. The trials compared performance of LED street and parking area luminaires with conventional technology in each city, typically high pressure sodium (HPS) lamps. Key findings were:

  • Average of 58% energy savings among 29 LED products, nearly a third showing energy savings of 70% or more;
  • Only 10 failed units out of 553 LED tested, a low failure rate of 1.8%;
  • Most LED products achieved compliance with local lighting standards;
  • LED products exhibited greater color stability than conventional lamps on average;
  • 16 out of 26 LED products maintained or showed increased light output over 4,000 to 6,000 hours of operation;
  • Public survey respondents in four cities agreed LED lighting made them feel safer.

As the market matures, Canada stands to benefit from the LED revolution in terms of innovation and job creation. “Evidence from the global LightSavers trials should give government and investors greater confidence in Canadian innovation and manufacture of solid state lighting components,” said Philip Jessup, Director of LightSavers Canada and principal author of the report.

With over 100 solid state lighting firms and organizations and domestic sales of US$200 million annually in Canada, the report concludes that the country’s municipal and provincial governments should take steps to assure a prosperous domestic SSL industry by collaborating to rapidly increase market demand.
