Global Trials Show That LED Public Lighting Can Save up to 85% of Energy
The results of the Led Public lighting(Classic) streetlight test confirmed that these luminaires can save up to 85% of electricity compared to the prior art. The two-and-a-half-year pilot, named LightSavers, tested 533 LED lights in 15 trials in 12 cities, including New York, London, Hong Kong, Toronto, and Sydney.
The main findings of the report illuminate the clean revolution: the rise of LED public lighting and its implications for the city, including:
LEDs can achieve the expected 50% to 70% energy savings, combined with intelligent control can save up to 80% of the cost. The energy savings in the test ranged from 18% to 85%, with 20 of the 27 products saving 50% or more and 10 saving 70% or more.
Surveys in Kolkata, London, Sydney, and Toronto show that 68% to 90% of respondents support the promotion of LEDs throughout the city. Outstanding benefits include increased security and visibility.
LED public lighting lifespans range from 50,000 to 100,000 hours, indicating a high return on investment.
The "catastrophic" failure rate for LED products over 6,000 hours is about 1%, for example, up to 10% for ceramic metal halide lamps in similar time periods.
