New Report Shows LED Streetlights Give Huge Energy Savings

0 80

The latest worldwide study into the benefits of LED street lighting has concluded that this new lighting technology can deliver electricity savings of up to 85% when compared to current lighting solutions.

The study has taken place over a two and a half year period, testing LED lamps in cities across the world including New York, London, Hong Kong, Toronto, and Sydney. The findings were first presented at the latest G20 summit in Rio, with the aim to speed up the implementation of eco-friendly outdoor LED lighting technology in order to take immediate advantage of the proven energy-saving benefits.

Some of the key findings of the study include:

  • The typical energy savings produced by the LED street lights tested achieved 60-70%, but this was improved to up to 85% when combined with intelligent lighting controls.
  • In conjunction with the LED lamp tests, surveys were carried out with residents of the cities in question and an overwhelming majority of respondents were in favour of a city-wide implementation of the new LED lighting technologies.
  • The LEDs tested had bulb lifespan ranges of between 50000 and 100000 hours, providing a host of other benefits including reduced maintenance and replacement cost and increased return on investment.
  • The failure rate of the LED lamps when tested over 6000 hours of operation was just 1%, compared to up to 10% for ceramic metal halide fixtures over a similar time period.

So confident are the report authors in the potential of LED lighting they want LEDs to become the global lighting standard. “All new public lighting – both street lighting and in public buildings – should be LED by 2015, with the aim of all public lighting being LED by 2020,” said a spokesman for the Climate Group in a statement.
