International. After two and a half years of research, in which LED lights were installed on the streets of 12 cities, including New York, London and Sydney, the LightSavers project revealed that they achieved 85% energy savings compared to the areas that were not intervened.
According to the study, the failure rate of LED products before 6,000 hours of use is around 1% compared to, for example, the 10% of conventional lighting during a similar period of time of use.
In addition, he points out that the LED market is at a tipping point, with the white light of the LED (used in outdoor lighting) in the first stage of the technology curve. Market penetration will accelerate to an expected figure of close to 60% in 2020.
Responses to surveys conducted in Kolkata, London, Sydney and Toronto, included in the study, indicated that citizens prefer LED lighting between 68% and 90% of respondents support the deployment of this technology throughout the city.
The LightSaver study concludes that LEDs are now sufficiently developed to be used in most outdoor applications, bringing economic and social benefits to society.
Based on these arguments, The Climate Group, in partnership with manufacturers such as Philips, are calling for an international lighting standard that creates and guarantees citizens around the world access to energy efficient outdoor lighting, a proposal set out in the document Illuminating Clean Revolution: The Rise of LED in Street Lighting and its Meaning for Cities, presented at the last Rio +20 summit, held in Brazil.
